Accuracy notes

Work on the devices only may be exported to the avoidance of heavy bodily injuries or considerable damages to property by qualified persons. These persons must carefully read the manual before the installation and getting started. Besides the manual and the national obligatory rules to the ac-cident prevention the recognised technical rules have to be adhered. (UVV, VBG, VDE etc.)

Repairs at the device may done only by persons, which are authorised by the manufacturer for the repair jobs.

The guarantee goes out at opening unauthorised and not qualified interventions!

The speed controllers are assembled in the steel sheet case (protection class IP54). This protection class is guaranteed only at inferred device!

Dangerous electrical voltages lie with open regulation device freely. The protection class of the open device is IP00! At work on regulation devices standing under voltage the valid national accident prevention prescriptions (UVV) have to be observed.

Use as agreed

Make sure that fuses may be replaced only in the said strength and not repaired or bridged. Voltage freedom may be checked only with a two-pole voltage indicator. The regulation device is exclusively meant for the tasks agreed in the job acknowledgement. A use which is other or this going beyond valid when not regulation appropriately. The manufacturer isn't liable for damages arising from this. Adhering to the approach described in this manual also is part of the use as agreed at packaging, mode and maintenance. Are the technical data as well as the details on terminal occupations to take from the types signpost and the instruction and to adhere absolutely.

In principle, electronic equipment’s aren't loss safe! The user has to take care for this therefore that his installation is led into a sure status at loss of the device. Damages to body and life as well and assets don't lie in the responsibility of the manufacturer at no observance of this point and at im-proper use. The electrical installation has to be executed after the appropriate prescriptions. Details going out are contained in the documentation on this. If the regulation device in a particular application area comes in use, then the standards demanded for this and regulations have to be adhered absolutely (e.g. EN 50014 and EN 50018).

Indication for the getting started

Before putting into service of the control equipment has to be checked, whether perhaps remains humidity scolded himself in this-cabinet has educated himself. The device has yes, so to be dried if. With larger condensed water crowds (Large drops of water on the walls or the components) these have to be removed manually. After the first getting started may the electrical power supply as well as the internal control voltage not switched out a longer time period any more be. Is this mode con-ditionally nevertheless required then a suitable humidity protection is to provide.

1.General Information

The GWR/GIRW is a microprocessor controlled Controller for regulating the speed of motors in ac-cordance with the phase cut principle. The output voltage can be adjusted from 0 to 100% of the mains voltage. They operate as a PT1 - Regulator (Proportional Regulator with fixed Reset Time).

Difference between GWR and GIRW:

The difference is, that the GWR has only 1 Output and no Main Switch, and the GIRW has 1-3 Out-puts and a Main Switch. Also, each output of a GIRW is protected by fuses, and the thermo contact of the fan is watched by the controller to switch off a faulty fan with a relay. The other fans are then still running.

1.1 Safety notes, Use for Determination

To prevent heavy bodily injuries or considerable material losses works on this equipment have to be done by persons with qualifications in mounting Speed Controller. These persons must carefully read the instruction before the installation and putting into operation. Besides the instruction and the national obligatory rules to the accident prevention there are the technical rules are to be take into account (the recognised technical rules have to be adhered safety-and professional work to UVV, VBG, VDE etc.)

Repairs at the piece of equipment only may be carried out by the manufacturer or repair places authorised by him. The guarantee goes out at opening unauthorised and improper interventions!

The speed controller is built in a steel sheet system-unit with IP54 protection. This protection is only guaranteed with closed unit!

Dangerous electrical tensions lie open if the equipment opened freely. The open equipment has IP00 protection! At work on rule pieces of equipment standing under tension the valid national accident prevention regulations (UVV) have to be observed.

Please note, that Fuses have to change with the same value that was built in. Fuses should not re-paired or bridged. Tension liberty may be checked only with a bipolar voltage indicator.

The Controller is only constructed for the usage that is specified in the order note. As agreed a use which is other or this going beyond is valid when not. The manufacturer isn't liable for damages arising from this. Adhering to the approach described in these operation instructions also is part of the use as agreed at packaging, operation and maintenance.

Are the technical dates as well as the details on terminal occupations to take from the type signpost and the instructions and to adhere absolutely.

In principle, electronic equipment’s aren't failure safe! The user has to take care for this therefore that his installation is led into a sure state at failure of the equipment.

The electrical installation has to be carried out after the appropriate regulations (e.g. management cross-cut, protections, protection ladder connection ...). Details going out are contained in the documentation on this.

If the controller in a particular application range comes to use, then the standards demanded for this and regulations (e.g. EN 50014 and EN 50018) have to be adhered absolutely.

1.2 Model number (Ordering key)

1. Controller Type GWR (GWR/GIRW = Phase control) or GIRW

Explanation: GWR = standard type with 1 Fan Output. GIRW = with main switch, Motor Control, load relay and up to 3 Motor groups with departure protectors. The faulty motor on a GIRW becomes galvanic seperated from the net. At the GWR switched off the motor power supply in the error case.

2. Nominal current /5 = 5 Ampere (1 x 5A or 2 x 2,5A or 3 x 1,65A) or /10 = 10 Ampere (1 x 5A or 2 x 5A or 3 x 3,35A) Explanation: This detail refers to the complete Motor current. If

several Motors are attached, the complete nominal current of all Motors mustn't exceed this value.

3. Protection class IP = IP54 Explanation: IP stands for the IP54 protection class. This class is

only reached in a closed case.

3.1 Main switch GIRW with main switch declared by EN60204 1/VBG4

4. Control system U = Unifunction (1 Control system, 1 Sensor) or M = Multifunction (2 Control systems, 1 or 2 Sensor) Explanation: The /U controller has 1 regulation system, the /M

controller has 2 regulation systems. You can attach 1 standard signal, 1 temp. probe or 1-2 Pressure Transmitter to every regula-tion system.

5. Number of Motor groups 1 = 1 Motor group 2 = 2 Motor groups 3 = 3 Motor groups

Explanation: The GIRW is deliverable for 1-3 Motor group(s), in which the number of Motor groups is indicated with /1, /2 or /3 at the end of the type key.

Examples:

GWR 5 IP U = Alternating current controller (5A), Unifunction, 1 Motor Output (The GWR have always only 1 Motor Output; if you need 2 or 3 Outputs, you have to order a GIRW.)

GIRW 5 IP U 2 = Alternating current controller (5A) for 2 Motors, Unifunction, with Main switch and Motor monitoring

GIRW 10 IP M 3 = Alternating current controller (10A) for 3 Motors, Multifunction, with Main switch and Motor monitoring

Special functions aren't covered with this equipment’s key. An adaptation to special control func-tions is possible in the work by special software for the short term.

2. Assembly

2.1 installation using the EMV rules

The controllers of the series GWR/GIRW...IP fulfil the requirements to the EMV interference immu-nity in accordance with EN 50082-2 and in accordance with disturbing emission EN 50081-1. It becomes the respectively stricter standard fulfilled with that. To ensure this EM compatibility, the following points have to be observed:

• The equipment must be grounded well

• All of them measure- and signal lines (only measuring wires use e.g. LIYCY 3 x0.5² no tele-phone lines) must be screened.

- the screening of measure- and signal lines single-sided to ground - ground the screening of the motor wires -- on both sides

• Signal and control lines are too in embarrassment, e.g. separated from net and Motor wires in separate cable channels.

2.2 Assembly and ventilation

If the equipment was taken from a very cool bearing place, you let it rest at space temperature and open lid before the installation 1-2 hours to let possible remains humidity escape and avoid break-downs at the putting into service so. The Silicagel bag (dry average bag) must be removed.

To the packaging 4 fastening straps are appropriate at the case. The fastening may be carried out only at these straps, any manipulations at the case (e.g. drills of new fastening holes) are forbidden.

The cable inlets must always be below. No packaging may be carried out with lateral or above lying cable inlet!

If all available cable inlets are used, then a cable inlet can at least be provided with a hole so that an air exchange is ensured by condensed water to the avoidance.

Pay attention to good accessibility! For possible maintenance work the equipment must be attain-able easily, special then, if a main switch is integrated.

The warmth arising in the power part is led away about the case directly, a warming is therefore normal. For this reason, however, a sufficient ventilation of the equipment also must be ensured so that the arising warmth can be led away! Take into account therefore:

• at packaging in the control cubicle this must be ventilated or air-conditioned.

• to prevent heat concentration, it is not allowed to assemble the controller above each other. The line up of arbitrarily many equipment’s besides each other (50 mm) permissible.

• a weather protective roof is specified outside.

• assemble you so, that the controller is protected about direct sunshine, and you choose an as weather-protected place as possible.

• to the top and bottom you have to keep a minimum space of 100mm, for the circulation of air must be possible.

2011-03-31 of 37 Version 4.1 GWR5

2.3 Wiring, Protection

For the Motor wire no screened line is specified.

Control lines must be lay separate, if they are immediate with other lines in the same line way or if they are longer than 20m. Otherwise there are couplings of drop-ins.

In principle, sensor lines are separated from the motor and too embarrassed therefore not in one common to mains power lines cable channel. Screened wire is recommended.

3. AC Power- and Motor Connection

The terminals for the load circuit and the volt-free reporting outputs are on the lower power board. The connections for the control inputs (regulator release etc.) and sensors are on the upper control board.

3.1 AC power supply

The Main connections (230V / 50Hz) are:

L = Phase (Line) N = Neutral PE = Protection Earth

The terminals are made for a maximum wire cross-cut of 2.5 mm². At use of wire braids wire-end sleeves must be used.

The power supply is to protect with a fuse automate of protection characteristics „B“ or „C“. For the controller types

GWR5/GIRW5 a 10A fuse and for GWR10/GIRW10 a 20A fuse is to use.

The controller himself has a fast fuse (6,3x32mm) to protect semiconductors and motors.

The value of the fuses are listed in the following table:

Controller Type Fuse for AC supply Fuse for output GWR5 FF 10A --- GWR10 FF 20A --- GIRW5 FF 10A FF 8A GIRW10 FF 20A FF 12,5A

Take of the characteristics „FF“ (super fast) and „T“ (slowly) of the fuses.

IMPORTANT: Switching on or off the regulator may not done by switching on or off the power sup-ply. The only way is to switch the release contact (FG, „Freigabe“).

3.2 Motor connection, Thermal contact

The Motor is to connect on following terminals:

U1, N1 = Terminal for Motor 1 U2, N2 = Terminal for Motor 2 U3, N3 = Terminal for Motor 3 PE = Protection earth TK = Thermal contacts of the Motors

To each motor terminal there belong two terminals „TK“, on which the thermal motor protection (Klixon, Bimetal) is to connect.

General: Not used TK-terminals must be bridged with wire!

2011-03-31 of 37 Version 4.1 GWR5

All available TK-terminals are bridged with wire ex works. Remove only a wire bridge if a motor with thermal contact is connected.

NOTICE: Only the connection is of voltage adjustable motors permissibly!

If you have doubts about the usability of the motor, you ask the manufacturer so whether an opera-tion is possible.

If several Motors must be attached to one terminal, the following has to be taken into account:

• the thermal contacts are to connect in succession!

• the complete Motor current mustn't exceed the permissible controller nominal current!

• connect the Motor wires in suitable place (e.g. with separate sticking box) and cram no more veins into the terminals with force!

At the settlement of fans by means of phase control (GWR/GIRW) vibrations arise which can make themselves noticeable as Motor noise. These however don't affect the Motor function life time nega-tively.

4. Volt-free reporting outputs

The potential-free reporting outputs (change contact) are so designed, that if an error appears, the contact opens also as if there is no power supply. The change contact therefore closes and it is pos-sible to switch on a bypass circuit for the fans to take the cooler into a failsafe state.

4.1 Fault warning relay („Sammelstörung”)

The fault reporting relay has the contacts 11/12/14. A fault is reported to the following situations:

• motor overheat (thermal contact has switched) • sensor defect (e.g. cable disruption)

If a trouble appears, the red fault warning LED lights up and the fault reporting relay is switched i.e. the change contact 11/12 closes. This volt-free contact may be loaded with max. 250V/1 A.

In case of a sensor fault (and only then) flashes in addition the green LED „Run“.

4.2 Threshold relay (Relay 1):

You can adjust the threshold value by the „Xe“ knob. If the sensor signal rises above this value, the threshold relay will be switched. For example, with this relay you can activate a bypass circuit.

sensor signal under threshold value, contact 21/24 closed sensor signal above threshold value, contact 21/22 closed

The red threshold LED light up, in order to display the condition. (LED „SW-1“). If you have a control System with 2 regulators, a additional second red LED „SW-2“ is inside the case.

Notice: The threshold is not a fault, it is only a switch point.

This volt-free contact may be loaded with max. 250V/1 A.

5. Control Inputs and RESET

The control inputs are designed for small voltage and are to be connect via volt free contacts (e.g. relay, switch, etc.) to +24V (terminal P).

You may under no circumstances lay out the line voltage here or work with another voltage!

This controller is designed with a microcontroller and therefore a RESET button is available.

5.1 Release contact (FG, „Freigabe“)

The controller is released via the terminal „FG“. The control voltage is 24V. If the terminal FG is switched to +24V, the controller is released and the green LED "Run" is illuminated. If the contact is left open, the motor is switched off and the green „Run“-LED is dark.

If the release function is not required, the terminal FG is to bridge by wire to +24V (terminal P)!

External Release Contact

The release terminal is bridged by wire ex works.

IMPORTAND NOTE: You may under no circumstances disable the regulator by the fact that you in-terrupt the line voltage! Switching the supply tension permanently can lead to damages to the con-troller. There isn't a right to claim under guarantee at such damages!

2011-03-31 of 37 Version 4.1 GWR5

5.2 Speed Limitation (Night Limit)

With the terminal „NB“ the night limit can activated. If the terminal NB is switched to +24V, the night limit takes effect. The value of limit is to adjust with the potentiometer „Begr.“.

0% = full limitation, no output voltage at night 50% = half output voltage at night

100% = no limitation will be done at night

Night Limit with volt-free contact

5.3 Switching to Control System 2 (only /M-Controller!)

With terminal „RS2“ you can switch to the second control system by connecting RS2 to +24V (P). Control system 1 is disabled and takes no effect to the Fan regulation. Is there no connection to RS2, control system 1 is at work.

Switching from RS1 to RS2 with a volt-free contact

5.4 Reset-Button

With this button the control unit will be restarted. If the controller is blocked or so affected by ex-treme external conditions that it is not working properly, this button should be pressed briefly.

2011-03-31 of 37 Version 4.1 GWR5

6. Sensor connection, Adjusting the controller

6.1 Differences Unifunction / Multifunction (/U and /M)

The Unifunction Controller has one regulation system and one sensor input. The Multifunction Con-troller has two regulation systems and two sensor inputs.

Each sensor input can be connected to two pressure transmitter, one temperature sensor or one standard signal 0..10V switched at the controller. Only one type of sensor can be used at the same time. For two different cooling circuits or switching between Summer/Winter (2 Set Points) you have to use a M/ Controller.

Both regulators are the same in function and work to the same power output.

6.2 The Control parameter Set Point, P-Band and Threshold

There are setting knobs to adjust the regulator. These are Set-Point Xs, P-Band Xp and threshold Xe.

6.2.1 Set Point Xs:

The SET POINT determines the point at which the controller operates (starting point) . At this point the motor is not yet running, because the output voltage is very low (fans start at ≈30-40V). If the motor is required to start earlier, the set point is to reduce. The Set Point is shown in % of the sen-sor value (see below).

pressure transmitter 0-25bar: 0-100% = 0...25bar rel. temperature sensor GTF210: 0-100% = -30...+70°C standard signal 0-10V: 0-100% = 0...10V

Diagram Set Point Xs

2011-03-31 of 37 Version 4.1 GWR5

6.2.2 P-Band Xp:

The P-Band is used to set the working range of the controller. In this range the motor power is con-trolled from 0..100%. In an example:

You have set the Set Point to 12bar, the P-Band to 5bar, then the working range of the controller is between 12bar with motors stand still and 17bar were the motors have full speed.

Full motor speed reduces the pressure in the cooler, so the motor power will be reduced and so on. This works as long, till an even point is reached.

To adjust this even point, you have to regulate the Xs Knob. If there is an oscillation by the even point, you can reduce this by enlarging the P-Band.

All this regulation has to be done carefully.

The P-Band is shown in % of the sensor value (see below).

Pressure transmitter 0-25bar: 0-100% = 2...25bar Temperature probe GTF210: 0-100% = 5...+40°K Standard signal. 0-10V: 0-100% = 1...10V

6.2.3 Threshold Xe:

With this button you can adjust the THRESHOLD value. If the sensor signal is above this value, the threshold relay will switch (Contact 21/22 is closed).

The threshold has no effect to the Set Point or the P-Band.

Application examples:

1: Bypass wiring

With the threshold relay a Bypass is steered for which connects the regulator output with the net directly (regulator detour).

The Bypass is attached so, that it puts on when closing the contacts 21/22, i.e. if the threshold relay falls.

With this measure you obtain an additional safety:

• If the sensor signal rises about the oriented limiting value now, the fans are operated at the net under detour of the regulator directly. e.g. because the power part of the regulator is faulty. This is known as 2-Point regulation.

• Even if the controller is suddenly current-free, a need operation is ensured to the installation since the threshold value relay in this case also falls and the Bypass wiring is activated. e.g. short-circuit which leads to the failure of the tension supply for the controller.

2: Fan operation report

If you need an operation report for the fan, you can create this with the threshold value relay:

Adjust the threshold value exact to the set point value, e.g. if the set point is set to 12bar, adjust the threshold also to 12bar. The threshold value relay switches now as soon as the regulator produces an output voltage and steers for the fan.

Note: The threshold value of the just active regulation system is always effective at the /M regulator with 2 regulation systems. You recognise this by the LED "RS1" or "RS2" (green) corresponding to this one at coming on.

6.3 The Adjust Buttons „Sockelspannung“ and „Begrenzung“

These two Potentiometer have an effect on the power part independently of the Regulator type (/U or /M) directly and have influence on the settlement no. You can take the position of the Potenti-ometer from the graphic at picture 8.1.1.

6.3.1 Speed Limitation (Begrenzung):

With the knob „Begrenzg.“ the output signal „Q“ becomes limited to the value of the potentiometer. Therefore the fan speed is also limited. The value of limitation is in range of 0..100%. That means:

100% = there is no limitation. The output voltage is 230V 50% = there is a limitation to an output voltage of 115V 0% = there is a maximum limitation. The output voltage is 0V

To activate this function, the terminal „NB“ = (Nacht- Begrenzung) is to connect with an external volt-free contact to the terminal „P“ (+24V). Is there no connection to terminal „NB“, no limitation is done.

To activate and adjust the speed limit do following steps:

• adjust the potentiometer „Sockelspannung“ to 100%. All fans must run with full speed. • activate Speed limit (e.g. with a wire bridge from NB to P) • adjust with potentiometer „Begrenzg.“ to the fan speed you want • adjust „Sockelspannung“ to 0% and remove the wire bridge • done

6.3.2 Manual Button (Sockelspannung):

A minimum output voltage can be adjusted with the Potentiometer "Sockelspg". With these mini-mum revolutions per minute the fan runs as soon as the regulator is released even if the regulation signal zero is.

This function can serve as hand plate for test and examining purposes (e.g. at the putting into ser-vice).

At normal regulation function this Potentiometer must stand on 0%!

The Potentiometer value is from 0 to 100% and refers on the line voltage (230 V). The value 50% means 115V output voltage. Since fans have a square characteristic, half tension doesn't mean halved revolutions per minute automatically either! If you liked to provide definite minimum revolu-tions per minute with the manual button, lets himself determine this only by practical trials.

2011-03-31 of 37 Version 4.1 GWR5

6.4 Selecting the type of regulation (only /M-Controller!)

Two regulation systems and two sensor inputs are available at the multifunction controller. Every sensor input can connected with 1-2 pressure transmitter or 1 temperature probe or 1 standard signal 0-10V.

There are three ways to use the two regulation systems. First, you connect only one sensorinput 1 to measuring transducer and switch between regulation system 1 and 2 with different set points. Sec-ond, you connect a measuring transducer to each sensor input and switch extern between the two different regulation systems. e.g. pressure and temperature. Third, the same as second, but the con-troller switches himself between the two regulations systems. He selects the sensor input with the maximum sensor value.

To change the controller function, a switch „Regelfunktion“ is on the controller board.

The 3 Functions are: Position 1 (left): MAX-Selection (2 Sensors) Position 2 (middle): Set Point switch (1 Sensor) Position 3 (right): System switchover (2 Sensor)

6.4.1 Set Point switch

With the function Set Point switch one measuring transducer is to connect to Sensor input ES1. It is used for both regulation systems (RS1 and RS2).

Switch the input selector to the corresponding position.

Input selector ES1 up P (1-2 Pressure transmitter) middle S (1 Standard signal 0-10V) down T (1 Temperature probe)

The sensor signal is passed on to the two regulation systems RS1 and RS2. Both regulation systems cause adjusting appropriately a rule signal (Q) for the output voltage now. Which of these two sig-nals is led to the common power part actually and the fan speed regulates are fixed by the alloca-tion of the input terminal "RS2":

Terminal „RS2“ open -> RS1 working (Set Point 1) Terminal „RS2“ closed to +24V („P“) -> RS2 working (Set Point 2)

This switch over will be shown by the green LED‘s „RS1“ or „RS2“. The threshold relay takes effect from the working regulation system.

Application example: Day/night or summer/winter switchover at condenser or dry cooler.

6.4.2 System switchover:

Two sensors are attached at the system switchover:

Sensor for regulation system RS1 to terminal ES1 Sensor for regulation system RS2 to terminal ES2

You don't have attach but be able to combine arbitrarily two equal-type feelers. You only take, that you care have adjusted the attached feeler type ES1 and ES2 at the choice switch correctly:

Selector ES1/ES2: up P (1-2 Pressure transmitter) middle S (1 Standard signal 0-10V) down T (1 Temperature probe)

The sensor signal on terminal ES1 is connected to regulation system RS1 and the sensor signal on terminal ES2 is connected to RS2. Each regulation system has his own sensor. Both regulation systems built an own output voltage, but only one system at once is connected to the power output. Terminal RS2 shows which system is connected to the power out-put.

Terminal „RS2“ open (no connection): RS1 steers fan speed Terminal „RS2“ closed to +24V („P“): RS2 steers fan speed

This switch over will be shown by the green LED‘s „RS1“ or „RS2“. The threshold relay takes effect from the working regulation system.

2011-03-31 of 37 Version 4.1 GWR5

6.4.3 MAX-Selection:

The MAX-Selection is the same as system switchover: 2 regulation systems, 2 sensors. The differ-ence is the switching of the regulation systems.

It will not be switched by an external signal. Internal the regulation system, which produced the maximum output voltage will be connected to the power output.

The terminal „RS2“ has no effect.

Application example: A cooler with two circulation and different frost medium. The pressure in each circulation is detected by separate pressure transmitters. Therefore you need different charac-teristics for the fan speed. The circulation, which needs the highest fan speed will be used to gener-ate the output voltage. That’s the meaning of MAX selection.

On following illustration you see the position of the 3 switches and see the connection-sticking on the upper Regulator circuit. In addition be able to recognise you the position of the light-emitting diodes and the regulation knobs.

The following graphic makes easier adjusting the regulation system:

Front Panel

2011-03-31 of 37 Version 4.1 GWR5

You can read the regulation range for the adjusting of Xs and Xp directly. You can the other way round determine the parameters of Xs and Xp for a desired regulation range.

Diagram of Controller Adjust

Xs is prepared for 50% and Xp on 15% in the example. You plumb from these two points to the right up to the diagonals and you can read the corresponding results on the horizontal axis for pressure, temperature or standard signal . Xe was elected freely, here for 70%.

You can the other way round select your field of work on the horizontal axis and determine the re-sults on the vertical axis for Xs and Xp correspondingly.

2011-03-31 of 37 Version 4.1 GWR5

6.5 Sensor Connection

The Unifunction Controller has one regulation system and one sensor input (ES1). The Multifunction Controller has two regulation systems and two sensor inputs (ES1 and ES2).

Each sensor input can be connected to two pressure transmitter, one temperature sensor or one standard signal 0..10V. Only one type of sensor can be used at the same time. Which sensor type you use is to adjust on the input selector switch.

Input selector ES1/2 up P (1-2 Pressure transmitter) middle S (1 Standard signal 0-10V) down T (1 Temperature probe)

The connection is described to the two sensor inputs following.

6.5.1 Sensor Connection on regulation system 1 (Terminal ES1)

6.5.1.1 Pressure Transmitter

One or two sensors (2 wire sensor) can be attached:

+24V = Common supply voltage (GS4003: red wire, GSW4003: wire „1“) 1B1 = Signal 4-20mA of sensor 1 (GS4003: blue wire, GSW4003: wire „2“) 1B2 = Signal 4-20mA of sensor 2 (GS4003: blue wire, GSW4003: wire „2“)

Connection of 1 or 2 Pressure Transmitter to ES1

If you attach two pressure transmitter, the respectively larger signal is escorted further and con-sulted to the speed control (MAX-Selection)

Note: Older 3 wire sensors with 4-20 mA signal output can be attached also, however need a chassis ground potential in addition. You can attach this at the terminal "GND".

If you have to connect a pressure transmitter with a 0..10V signal output, you have to select on ES1 the Standard signal option. Therefore, only one pressure transmitter can be connected to terminal 1Y.

Important: Please, consider that at use of purchased parts which don't date from GÜNTNER there isn't a guarantee!

2011-03-31 of 37 Version 4.1 GWR5

6.5.1.2 Temperature Probe:

The connection of a temperature probe is always carried out at the terminals

GND = Ground 1B3 = Signal Input

At this not cares about the order of the wires.

Connection of a Temperature probe to ES1

The GÜNTNER temperature probe GTF210 is used in the range of -30...+70s ° C. Please, for other temperature ranges contact us.

If you have the suspicion that the probe is faulty, you can disconnect him from the regulator and measure the resistor of the probe (with a ohmmeter). With the following table you can check whether the probe shows the right resistor at a known temperature.

Resistor Temperature Resistor Temperature 1040 Ω -50°C 2152 Ω 35°C 1095 Ω -45°C 2230 Ω 40°C 1150 Ω -40°C 2309 Ω 45°C 1207 Ω -35°C 2390 Ω 50°C 1266 Ω -30°C 2472 Ω 55°C 1325 Ω -25°C 2555 Ω 60°C 1387 Ω -20°C 2640 Ω 65°C 1449 Ω -15°C 2727 Ω 70°C 1513 Ω -10°C 2814 Ω 75°C 1579 Ω -5°C 2903 Ω 80°C 1645 Ω 0°C 2994 Ω 85°C 1713 Ω 5°C 3086 Ω 90°C 1783 Ω 10°C 3179 Ω 95°C 1854 Ω 15°C 3274 Ω 100°C 1926 Ω 20°C 3370 Ω 105°C 2000 Ω 25°C 3467 Ω 110°C 2075 Ω 30°C

2011-03-31 of 37 Version 4.1 GWR5

6.5.1.3 Standard signal 0-10V:

The connection of a standard signal (0-10 V) is always carried out at the terminals

GND = Ground (negative) 1Y = Signal input 0-10V (positive)

Pay attention to the right polarity (chassis ground to GND, signal to 1 Y)!

Connecting a Standard signal or Handpoti GHP on ES1

You also can alternatively attach a Güntner Handpoti GHP as a remote control. The terminals of the GHP are either with 1/2/3 or +/- Y labelled. + or 3 to +24V - or 1 to GND Y or 2 to 1Y The controller then has to be adjusted as follows: Set point Xs = 0% (=0V, on the left stop) P-Band Xp = 100% (=10V, on the right stop) You then can use the controller for rotation control (or step control) manually. This is used also for external control with a frost machine. In this case, the frost machine generates a control signal for fan regulation. 6.5.1.4 SLAVE-Control:

If you use the regulator as 'Slave' in a Master-Slave combination, you have to adjust the set point and P-Band in the same way (Xs = 0%, Xp = 100%).

2011-03-31 of 37 Version 4.1 GWR5

6.5.2 Sensor connection to regulation system 2 (Terminal ES2)

6.5.2.1 Pressure Transmitter:

1 or 2 sensors can be attached:

+24V = power supply (GS4003: red wire, GSW4003: wire „1“) 2B1 = signal 4-20mA from sensor 1 (GS4003: blue wire, GSW4003: wire „2“) 2B2 = signal 4-20mA from sensor 2 (GS4003: blue wire, GSW4003: wire „2“)

Connecting 1 or 2 pressure transmitter to ES2

If you attach two pressure transmitters, the respectively larger signal is passed on to the regulation system RS2 and consulted to the speed control (Max choice between the two pressure transmit-ters).

Note: Older 3 wire sensors with 4-20 mA signal output can be attached also, however need a chassis ground potential in addition. You can attach this at the terminal "GND".

If you have to connect a pressure transmitter with a 0..10V signal output, you have to select on ES1 the Standard signal option. Therefore, only one pressure transmitter can be connected to terminal 1Y.

Important: Please, consider that at use of purchased parts which don't date from GÜNTNER there isn't a guarantee!

2011-03-31 of 37 Version 4.1 GWR5

6.5.2.2 Temperature Probe:

The connection of a temperature probe for RS2 is always carried out at the terminal:

GND = Ground 2B3 = Signal input

At this not cares about the order of the wires.

Connecting a temperature probe to ES2

For further details look at the description of connecting a temperature probe to ES1

6.5.2.3 Standard signal 0-10V

The connection of a standard signal for RS2 is always carried out at the terminals:

GND = Ground 2Y = Signal input 0-10V

Pay attention to the right polarity (chassis ground to GND, signal to 2Y)!

6.6 System panels (Status-LED’s)

You inform the lettered light-emitting diodes about the current regulator status.

LED “Run“ (green): off = no release flashing = Sensor defect (therefore the LED ‘Fault’ is also on) on = controller is working

LED “RS1“ (green): on = regulation system 1 has effect to the fan speed off = regulation system 1 has no effect

LED “RS2“ (green): on = regulation system 2 has effect to the fan speed off = regulation system 2 has no effect (LED „RS2“ only at M-type controller)

LED “STÖRUNG“ (red): on = there is a defect (Motor defect, Sensor defect) off = no defect

LED “SW-1“ (yellow): on = threshold of RS1 exceeded off = threshold of RS1 not exceeded

LED “SW-2“ (yellow): on = controller is switched OFF (Q > 5%) off = controller is switched ON

6.7 Service unit GSGM (Available as accessories)

The service equipment GSGM makes easier adjusting the regulator and is helpful at the fault diag-nosis. With this handheld you can question on the single adjust potentiometer and information about the current system parameters. The GSGM is usable for all microprocessor controlled speed controllers.

Connection to the controller:

The service equipment is to contact to the 15 pole Sub-D sleeve. This can be done under process.

After carried out connection you must push in every case of the Reset button briefly so that the report "Guentner Elektro" appears.

The standard display is then represented (dependently) on the regulator type on the display, i.e. the current system value (pressure, temperature or tension), and the output (Q) in per cent is displayed.

E.g. if there is a trouble, then the error is shown instead of the standard display: "Keine Freigabe!", “Drucks. defekt!“ or „Motorstoerung!“

Adjust and queries of the operation parameters:

The controller is only to adjust, if there isn’t any fault. If e.g. the release is missing, the net rotating field is wrong or there is a Motor fault, the regulator is disabled and cannot be adjusted . Clear you in this case, before you adjust the regulator.

You find the following keys on the operating panel of the GSGM:

The operating panel of the GSGM

The keys are (of on the left to the right): Up, down F1 (function key) and enter.

The procedure was simplified fundamentally here: Attach the GSGM and look for the message „Guentner Elektro“. If it is not displayed within 5

sec., press the RESET button. Now the standard display appears (System value and signal "Q"). Now you can adjust the parameter with the corresponding potentiometer. To change to the

other parameter press the UP and DOWN buttons. You can leave the adjust menu every time by pressing the ENTER button.

Remove the GSGM. That’s all!

7. Primer to the fast getting in

The most important details are contained on this side to take the controller fast in operation.

This primer replaces under no circumstances the studies of the operation instructions!

Ac power supply: Ac power supply at the terminals L, N, PE (230V/50Hz) For the semiconductor and Motor protection fine protections are built-in in the regulator. Replace these only by the same types (size, current intensity, slow or fast).

Motor connection: Motor connection at the output terminals

U1, N1, PE = Motor 1 U2, N2, PE = Motor 2 U3, N3, PE = Motor 3

Don't exceed at most permissible regulator nominal current! (=Complete nominal current of all attached motors). For a short term, e.g. during the high run phase, are +20% permis-sible.

Thermal contact: For each motor group connection are scheduled 2 thermos contacts (TK). Therefore at fault each motor group can disconnected separately. The thermal contact isn't needed or the engine has about no overheating protection, the corresponding clamps must become shorted by wire!

Disturbing report: At a disturbance (Motor overheat, sensor defect or net fault), the disturbing reporting relay is switched (relay contact falls) i.e. the relay contact 11/12 closes.

Threshold relay: If the threshold value Xe of the active regulator is exceeded, the threshold value relay switches off (falls) i.e. the contact 21/22 closes. You occur for Bypass wiring mostly (regu-lator detour). This usually isn't a disturbance!

Regulator release: (LED the clamp "FG" is connected to +24 V (clamp "P"), are the regulator opened and be drive ready (green LED "Run" shone out), otherwise jammed. Is terminal „FG“ connected to +24V (Terminal „P“), the regulator is released and clear for operation (green LED „Run“ shines), in other way the controller is locked (LED off). Never connect extern voltage to FG. If the release isn't needed, this connection is to bridge with clamp "P" forever!

Clipping: If the terminal „NB“ (Night limit) is connected to +24V (terminal „P“), the Fan speed is limited to the value which is adjusted with the potentiometer „Begrenzg.“

System switching (only /M-Controller): If the terminal "RS2" gets connected to +24 V (terminal "P") regulation system 1 (RS1) is switched over on regulation system 2 (RS2), otherwise is RS1 active.

Regulation function (only /M-Controller): The mode switch „Regelfkt.“ selects the regulation function: Pos.1 =MAX-Ausw.: 2 sensors,2 RS; both RS active, max signal controls fan speed Pos.2 =Sollw.: 1 sensor, 2 regulation systems (RS) Pos.3 =2Regels.: 2 sensors, 2 regulation systems (RS).

RESET-knob: If the regulator works no longer correctly, you push this knob. Briefly a regulator lock by repeated Fan defaults is lifted hereby also.

2011-03-31 of 37 Version 4.1 GWR5

Sensor connection: Sensor for regulation System RS1 to terminal ES1 (Eingangs-Signal 1): Pressure transmitter (4-20mA): „+24V“ = Supply voltage (wire ‘1’)

„1B1“and/or „1B2“ = Sensor 4-20mA (wire ‘2’) Temperature sensor GTF210: „GND“ = brown wire

„1B3“ = white wire Standard signal 0-10V: „GND“ = Ground (Minus)

„1Y“ = Signal 0-10V (Plus)

Sensor for regulation System RS2 to terminal ES2 (Eingangs-Signal 2, only /M-Controller): Pressure Transmitter (4-20mA): „+24V“ = Supply voltage (wire ‘1’)

„2B1“and/or „2B2“ = Sensor 4-20mA (wire ‘2’) Temperature sensor GTF210: „GND“ = brown wire

„2B3“ = white wire Standard signal 0-10V: „GND“ = Ground (Minus)

„2Y“ = Signal 0-10V (Plus)

The attached sensor type must be adjusted at the corresponding select switch "ES1" or "ES2": above = pressure, middle = standard signal, down = temperature.

Adjusting the regulator: Both regulation systems are identical in their function and have an effect on the same power supply:

• Set point Xs: The set point determines the cut-off of the settlement. Is this point exceeded, produces the regulator an output voltage (at the beginning still low: motor beginning only as of approx. 30-40 V, motor specific)

• P-Band Xp: With the proportional band the field of work of the regulator is adjusted. This value marks the end of the regulation range, going out of the set point. e.g. Set point = 12 bar, P band = 4 bar == > working area = 12-16 bar.

• Threshold Xe: Has no effect to the regulation, sets only the switch point for the threshold re-lay. Exceeds the sensor signal the threshold value of the regulation system, contact 21/22 switches.

• Manual button: A minimum output voltage (least revolutions per minute) can hereby be ad-justed. Serves for test and examining purposes as hand plate, must otherwise stand on 0%!

• Limitation: The output voltage is limited to the adjusted value in percent of the line voltage (e.g. 50% = 115V). External activation with terminal "NB" necessary.

8. Special Functions

Special functions aren't available at the standard regulator!

A special speed controller is marked with an preceding „S“ in the model number (e.g. S-GIRW 5 IP 3 M). Added features not explained here are described on a con-sheet which is enclosed with these mode instructions. Always keep both papers together!

9. Faults and their repair

9.1 General notes

Most errors which appear at the getting started have to be put down to errors the wiring or faulty sensors. The speed controller is actually faulty in fewest cases. Please, before you order a spare equipment, check the following points:

Ac power supply:

• Ac power correct?

• Ac voltage high enough? (230V +15% / -10%)

Motor connection:

• Thermal contacts of the fans OK?

• Not used thermal contacts are really shortened at the terminals?

Sensor connection:

• Correctly connected? Compare chapter sensor connection!

• Sensor OK? (Measure! pressure: 4-20mA, temperature: 1.2-2.7kΩ, standard signal: 0-10V)

• Loose contact? Put on to screws?

• Sensor wires lie in immediate proximity of power cords or motor cords? Maximising separation if necessary!

• Sensor wires screened? If not: Exchanges!

• Screening established at the controller single-edged?

Fuses: • Controller output fuses OK? (Measuring motor nominal current)

• Main fuses in the regulation device OK? (Test the fuses only fully developed!)*

• Protection against the lead to the controller OK?

Status light-emitting diodes: • Is the green „RUN“ LED on? If not: Checking release! (Put for testing wire link to +24V)

• The green LED flashes? If yes: Sensor defect! Check the sensors and the sensor connection.

• The red LED „Störung“ is on? If yes: Check the thermal contact of the motor! If this one flashes in addition green "RUN" LED, then they check the sensors.

Table for the fault diagnosis

fault Possible causes, proposals for solution Device doesn't deliver any output voltage, fan doesn't revolve.

Check the built-in fuses: If when switching the regulator on nothing happens and none LED comes on, the main fuses can have blown.

Is the green „RUN“ LED shining? If not, check if the release terminal is connected correctly.

Check the lead (phase loss) and the line for errors (cable disruption etc.) to the motor. Has the thermal contact of the motor triggered?

Is the sensor faulty? Check it:

2 wire pressure transmitter: there must be a sensor current of 4-20mA. You can also check the sensor voltage between GND and sen-sor. The value of 0,4-2,0V is OK.

Temperature sensor: Measure the resistance, it must have the value 1200-2700 Ohm. Smaller values indicate short-circuit (e.g. water in the connection box), higher values indicate loosen contacts or Cable disruption.

Standard Signal: Voltage can lie between 0-10V. If it lies permanently with 0 V, a defect is probable.

Motor doesn't reach his maximum revolu-tions per minute or turns in the normal mode too slowly.

Is the clipping active? The maximum motor speed is limited on the value here adjusted. Check the setting!

Perhaps the controller isn't adjusted correctly.

If you maximise the set point, the fan revolutions per minute in-crease. If this doesn't help either, you can carefully change the P Band. If the P Band is reduced, the motor reaches his maximum revolutions per minute earlier. Note: A too strong reduction of the P Band can create regulation vibrating! Increase P Band again, if this happens.

Does the sensor deliver a correct signal? If this is too low, the fan doesn't reach the required revolutions per minute. Check following things:

Temperature sensor: Was the sensor assembled correctly? In the proximity of heat sources or e.g. at direct sun ray treatment a wrong value is included. Check the sensor and the wiring!

Is the polarity correct? The ground of the sensor signal must be con-nected to terminal "GND."

Standard Signal 0-10V: Check the signal at the terminals with a mul-timeter. It must matter to a voltage between 0-10. Right polarity?

Pressure transmitter: The 2 wire sensor delivers 4-20 mA. Check this value (Ampere meter). The value doesn't lie in this range or the value remains constant also at pressure modification, the pressure trans-mitter is faulty.

You also can alternatively test the tension on the signal input against minus (GND). This value must between 0.4 -- 2.0 V.
