The frequency of testing or calibration is generally determined by local regulation or standards.There are two concepts that need to be differentiated: bump test and calibration

Bump Test: This consists of exposing the sensor to a gas. The objective is to establish if the sensor is reacting to the gas and all the sensor outputs are working correctly. A qualified bump test is a test carried out using ampoules or cylinders of known concentration.

Calibration: This consists of exposing the sensor to a calibration gas setting the zero or Standby voltage, the span or range, and checking/adjusting all the outputs, so that they are activated at a specified gas concentration.

Danfoss recommends annual checks by qualified bump test and replacement of the sensor PCB with a Danfoss pre-calibrated certified sensor PCB every two years. The mother PCB is at the same time tested with the GD tester.

The alternative to this is a full on site calibration. Sensor replacement should be more cost effective, eliminates end of life concerns, and constantly renews the detection system.

Procedures for bump test and calibration vary depending on the sensor technology used and the gas in question.

The GD is available in four sensor versions: Semiconductor (SC), Electrochemical (EC), Catalytic (CT), and Infrared (IR) for CO

2.

Before you carry out the test or calibration:

1. Advise occupants, plant operators, and supervisors.2. Check if the relays (Con6 and Con7) are connected to external systems such as sprinkler systems, plant shut down, external sirens and beacons, ventilation, etc. and disconnect as appropriate.3. Deactivate alarm delays with JP1 and JP2. See fig. 1. For this the GD must be powered off.4. For Bump Test the GD should be powered up overnight.

NOTE: If unit has been installed and running for about 24 hrs, and you need to power it off to set the delay at 0 min, then the warm-up is 2 min and you can begin the testing or calibration.

Ideally bump tests are conducted on site in a clean air atmosphere.

The bump test can be carried out on following types of GD (see table 1)GDA (qualified bump test)GDC (qualified bump test/ restricted bump test)GDHC (restricted bump test)GDHF (restricted bump test)GDHF-R3 (restricted bump test)

See table 1, to find the GD type and the corresponding Bump test method.

Checking the zero (0 Voltage output).See Appendix 1. (not required for IR sensor)

1. Remove the cover of enclosure of the GD

2. Make sure that both the ampoules and the calibration beaker are clean and dry (see fig. 5).

3. Unscrew the beaker hold screw and place the ampoule so that is sits in the base of the beaker (see fig. 2).

4. Tighten on the screw ampoule without breaking it.

5. For the models: Standard Basic Standard Basic with LCD display IP 56 enclosure IP 56 enclosure Low Temperature Screw in: EC/SC/CT-Adaptor or M35-Adaptor into the Beaker according to table 1.

Place the beaker with the EC/SC/CT-Adaptor over the sensor. It should be as tight fitting as possible to allow maximum exposure to the gas (see fig. 5).

BUMP TEST (every year)

For the GDC (CO2)models:

Standard BasicStandard Basic with LCD displayIP 56 enclosureIP 56 enclosure Low Temperature

Place the beaker over the sensor in a 45 degree (see fig. 3). This allows gas to flow through the back of the sensor and through the calibration ports.

For the models:IP 65 for High RH and Fast responseEExd modelEExd model Low TemperatureIP 66 enclosure 5 m remote IP 65 sensorIP 66 enclosure 5 m remote IP 65 EExd sensor

Screw/fit the beaker (possibly with M35 Adaptor) on the remote sensorhead (see fig. 4). It should be as tight fitting as possible to allow maximum exposure to the gas.

7. Connect volt meter to monitor sensor response. (Con3 pin 1 and 3 - see fig. 1).

8. Tighten on the ampoule until it shatters allowing the content to diffuse in the beaker. It should be left in place for approximately 5 min.

9. Voltage output will increase. This confirms that the sensor is responding. See Pass test criteria in table 1.

10. Carefully remove any ampoule remains from the gas detector, and reassemble the sensor enclosure.

Fill out the GD Bump Test Certificate (literature no.: PZ.S00.A).

Installation

General procedure for all GD types (fig. 2, 3, 4)

All GD products are for wall mounting.

Removal of GD top cover:- For Standard and LCD display types: Unscrew two front screws For IP 65, IP 56 and EExd types (fig. 3, 4): Unscrew four front screws

Electrical installation (fig. 5 and 6)The Earth/Ground connection must be made when using the standard, LCD display, or EExd enclosuretypes. The safety of the equipment is dependent on the integrity of the power supply and the earthing of the enclosure.

Apply voltage at CON 1 and the green LED will light up (fig. 6).

Stabilisation PeriodOnce the GD is initally powered up it takes some time to stabilise and will give a higher analog output (4-20 mA/0-10 V/0-5 V 1) ) at the start before reverting to the actual concentration reading (in clean air and no leaks, on the analog output reverts back to: (~ 0 V/4 mA / ( ~ 0 ppm)) 2).

The stabilisation times specified below are only intended as a guide and may vary due to temperature, humidity, cleanliness of the air, storage time 3) e.t.c

ModelGDA with EC sensor ...........................20-30 SecGDA with SC sensor ............................... 15 min.GDA with CT sensor ............................... 15 min.GDA with CT sensor, EExd model ........7 min.GDHC/GDHF/GDHF-R3 with SC sensor ............................................1 min.GDC with IR sensor ..................................10 sec.GDC with IR sensor, EExd model .................................................20 sec.GDH with SC senso ..................................3 min.

When changing any jumper position, the power must be disconnected (CON1) to enable the new jumper setting.

Adjusting Low/High alarm values (fig. 7)All GD have been preset by the factory to realistic values related to the actual ppm range of the GD product. The actual Low and High alarm ppm limits are detailed on the external GD label. The factory preset value can be adjusted, with a voltmeter measuring the 0-5 V d.c output.0 V corresponds to the min. ppm range (e.g. 0 ppm)5 V corresponds to the max. ppm range (e.g. 1000)E.g. if a setting of 350 ppm is required then the voltage shall be set to 1.75 V (35 % of 5 V)

Adjusting the Low alarm limit valueBetween TP0(-) and TP2(+) a voltage between 0-5 V can be measured and with that the ppm Low alarm limit setting.The voltage/ppm setting can be adjusted at RV1.

Adjusting the High alarm limit valueBetween TP0(-) and TP3(+) a voltage between 0-5 V can be measured and with that the ppm High alarm limit setting.The voltage/ppm setting can be adjusted at RV2.

Connecting GD to a Danfoss monitoring system (fig. 8 and 9)Wiring (fig. 8)All GD must be connected A-A, B-B,COM COM (screen)When connecting to the Danfoss monitoring system panel the same terminals are connected to each other i.e. A-A, B-B, Com Com.

On the last GD and Danfoss monitoring system, fit a 120 ohm resistor across terminal A and B to terminate the communications system.

A maximum of 31 GDs can be connected.If more than 31 units are needed, please contact Danfoss for further information.

GD address (fig. 9)The sensor address is set by S2 and S3, adjusting these dials between 0 and F will give the sensor its own address as shown in fig. 9. A conversion chart between Danfoss monitoring system channel numbers and the hexadecimal address of the GD is attached. Power must be removed when setting addresses on the GD.

1)Always use the voltage 0-10 V to check the output for stabilisation check.

2)GDC IR goes back to about 400 ppm as this is the normal level in air. (~4.6 mA/~0.4 V/ 0.2 V)

3)If the GD have been in long-term storage or have been swiched off for a long period, stabilisation will be much slower. However within 1-2 hours all the GD types should have dropped below the low alarm level and be operational. The progress can be monitored exactly on the 0-10V output. When the output settles around

zero (400 ppm in the case of IR CO2 sensors) the

GD is stabilised. In exceptional circumstances particularly with CT sensors the process can take up to 30 hours.

AnvendelseGD-testeren kan installeres i alle til rdighed stende gasdetektortyper.GD-testeren er derfor uafhngig af det anvendte klemiddel, det valgte ppm-omrde samt gasdetektormodel.

Med GD-testeren er det muligt at simuleregasdetektorens drift i hele ppm-omrdet,uden at det er ndvendigt at anvende klemiddel-kalibreringsgas p stedet.

Det er derfor muligt at teste alle funktio-nerne p gasdetektorens hovedprintkort. F.eks.: Digital alarm for lavt niveau / gul LED Digital alarm for hjt niveau / rd LED Forsinket responstid ved alarmer Analog udgang 4-20 mA Analog udgang 0-5 V Analog udgang 0-10 V Display (hvis installeret) Buskommunikation til Danfoss m2 (hvis installeret)

Ved det rlige (eller hyppigere) eftersyn af gasdetektoren anvendes GD-testeren i forbindelse med udskiftning af flerprintkortet til at udfre en endelig funktionstest af gasdetektoren og efterflgende udstede GD-kalibrerings-certifikatet.

InstallationFrakobl strmmen til gasdetektoren. Fjern CON1 (fig. 3).

Afmonter flerprintkortet. Lsn de tre skruer, som holder flerprintkortet p plads (fig.1, pos. 1). Fjern flerprintkortet ved forsigtigt at trkke printkortet lodret op og ud af hovedprintkortet.Monter GD-testeren. Installer GD-testeren i CON4 (fig. 3). Kontroller, at alle GD-testerens seks ben sidder korrekt i CON4.Genetabler strmmen til gasdetektoren. Geninstaller CON1 (fig. 3).

Drift af GD-testerenVed hjlp af potentiometeret VR1 (fig. 2) er det nu muligt at simulere hele gasdetektorens faktiske ppm-omrde med den installerede GD-tester.

VR1s faktiske indstilling kan overvges. Der kan tilsluttes et voltmeter (0-10 V d.c.) mellem TP (+VE 1) og TP0 med henblik p at simulere alle vrdier inden for ppm-omrdet.

Hvis VR1 drejes med uret, simuleres et faldende ppm-signal.

Hvis VR1 drejes mod uret, simuleres et stigende ppm-signal.

F.eks.Det originale flerprintkort har et ppm-omrde p 0-1000 ppm.

0 V mlt mellem TP (+VE 1) og TP0svarer til 0 ppm.

5,75 V mlt mellem TP (+VE 1) ogTP0 svarer til 575 ppm.

10,00 V mlt mellem TP (+VE 1) andTP0 svarer til 1000 ppm.

Det er sledes muligt at kontrollere neden-stende funktioner p gasdetektoren: Digital alarm for lavt niveau / gul LED Digital alarm for hjt niveau / rd LED Forsinket responstid ved alarmer Analog udgang 4-20 mA Analog udgang 0-5 V Analog udgang 0-10 V Display (hvis installeret) Buskommunikation til Danfoss m2 (hvis installeret)

GenmonteringNr alle funktionerne p gasdetektorens hovedprintkort er testet, skal GD-testeren fjernes.

Frakobl strmmen til gasdetektoren. Fjern CON1 (fig. 3).

Fjern GD-testeren.Installer nyt (eller eksisterende) fler-printkort. Kontroller, at alle seks ben p flerprintkortet sidder korrekt i CON4.

Tilslut strmmen til detektoren. Geninstaller CON1 (fig. 3).

DANSK

ApplicationGD tester can be installed in all types of available GD.The GD tester is thus independent of type of refrigerant used, selected ppm range and GD model.

With the GD tester it is possible to simulate GD Operation within the full ppm range, without any need for refrigerant calibration gas locally.

That means that all functions on the GD Mother PCB can be tested. E.g. Digital Low Level Alarm / Yellow LED Digital High Level Alarm / Red LED Delayed response time on Alarms Analog output 4-20 mA Analog output 0-5 V Analog output 0-10 V Display (if installed) Bus communication to Danfoss m2 (if installed)

At annual check (or more frequently) of GD, the GD tester is needed when replacing the sensor PCB in order to carry out a final function test of GD Gas Detector and sign the GD Calibration Certificate subsequently.

InstallationDisconnect power to GD.

Remove CON1 (fig.3).Dismount sensor PCB. Unscrew the 3 screws that holds the sensor PCB (fig.1, pos 1). Remove sensor PCB by carefully pulling the PCB vertically upwards from the Mother PCB.Mount GD tester. Install the GD tester at CON4 (fig 3). Ensure that all 6 pins on GD tester fit correctly into CON4.Reconnect power to GD. Reinstall CON1 (fig.3).

Operation of GD testerWith potentiometer VR1 (fig.2) it is now possible to simulate the whole actual ppm range of the GD with the GD tester installed.

The actual setting of VR1 can be monitored. Between TP (+VE 1) and TP0 a volt meter (0-10 V d.c ) can be connected in order to simulate any value within the ppm range.

Turn VR1 clockwise Correspond to simulate decreasing ppm signal.

Turn VR1 counter clockwise Correspond to simulate increasing ppm signal.

E.g.The original sensor PCB had a ppm range of0-1000 ppm.

0 V measured between TP (+VE 1) and TP0 correspond to 0 ppm.

5.75 V measured between TP (+VE 1) and TP0 correspond to 575 ppm.

10.00 V measured between TP (+VE 1) and TP0 correspond to 1000 ppm.

It is thus possible to check below mention functions of the actual GD: Digital Low Level Alarm / Yellow LED Digital High Level Alarm / Red LED Delayed response time on Alarms Analog output 4-20 mA Analog output 0-5 V Analog output 0-10 V Display (if installed) Bus communication to Danfoss m2 (if installed)

ReassemblyAfter all functions on the GD Mother PCB have been tested, the GD tester must be removed

Disconnect power to the GD. Remove CON1 (fig.3).

Dismount the GD tester.Install new sensor PCB (or exsisting sensor PCB). Ensure that all 6 pins on the sensor PCB fit correctly into CON4.

Reconnect power to the GD. Reinstall CON1 (fig.3).

Signal dampingSignal damping is factory-set at 15 seconds. This setting can be altered by activating the calibration switch. The setting range is 1 to 120 seconds. Settings can also be made whilst the system is operating.

Procedure:1. Connect the supply voltage.

2. Push the calibration switch once for each second by which you want to increase the damping. Example: 1. push to 1 sec. 2. pushes to 2 sec. etc. 120. pushes to 120 sec. 121. pushes to 120 sec.

10 seconds after the last push, the value will be saved in the memory and the green LED will start flashing again. After 10 seconds, a further push will start 1-second signal damping again.(If the damping setting is set too high, restart the procedure from step 1).

Min. calibration when minimum refrigerant level must be different from 4 mA:1. Bring the refrigerant liquid level to desired minimum level.2. Press the calibration pushbutton and keep it activated in approx. 5 seconds, until green LED stopps flashing.3. Activate, within the next 10 seconds, the calibration pushbutton once and keep it activated. (If calibration pushbutton is not activated within 10 seconds, it will automatically leave calibration mode and return to normal operation)4. Observe the output mA signal increasing fast starting at 4 mA.5. Release the calibration pushbutton when the output signal is approx. 0.5 mA from the desired point.6. All the next activations will increase the output signal by approx. 0.05 mA7. Approx. 10 seconds after the latest activation the LED starts flashing8. Output now corresponds to the value measured at the latest activation.

Max. calibration when maximum refrigerant level must be different from 20 mA:1. Bring the refrigerant liquid level to desired maximum level.2. Press the calibration pushbutton and keep it activated in approx. 5 seconds, until green LED stopps flashing.3. Activate, within the next 10 seconds, the calibration pushbutton twice and keep it activated. (If calibration pushbutton is not activated within 10 seconds, it will automatically leave calibration mode and return to normal operation)4. Observe the output mA signal decreasing fast starting at 20 mA.5. Release the calibration pushbutton when the output signal is approx. 0.5 mA from the desired point.6. All the next activations will decrease the output signal by approx. 0.05 mA7. Approx. 10 seconds after the latest activation the LED starts flashing8. Output now corresponds to the value measured at the latest activation.

Reset to factory settingAKS 41 can always be reset to factory setting regardless of any revised calibration values.1. Press the calibtation pushbutton and keep it activated in min. 20 sec, until green LED starts flashing2. Release calibtation pushbutton3. When LED starts flashing, reset to factory setting is completed.

InstallationBefore AKS 45 is fitted on the valve, the system must be emptied, shut off, etc. to prevent damage or injury.

AKS 45 is supplied with a nipple to suit the valve itself (see table above).1. Screw out the valve bottom plug. 2. Loosen the grub screw (fig. 3) on

AKS 45 so that the nipple turns freely.3. Screw AKS 45 with nipple into the valve

and turn it to the required position. Lock by retightening the grub screws.

AKS 45 transmitter for PM and MEV/MRV valves:Transmitter type AKS 45 - 26 AKS 45 - 67 (fig. 1) (fig. 2)Code no. 084H4045 084H4046For PM 5 - 65 PM 80 - 125valve size PML 5 - 65 PML 80 - 125 PMLX 5 - 65 PMLX 80 - 125 PMC PMFH PMFL MRV MEV Nipple M 24 M 35 (A/F 32) (A/F 41)

ENGLISH CalibrationWhen calibrating, AKS 45 will always apply an output signal of 4 mA at the first calibration point and an output signal of 20 mA to the second calibration point.AKS 45 is therefore able to indicate both a direct valve function, (PM, MEV/MRV valves) and a reverse valve function (PMFL valves).

AKS are calibrated as follows: 1. Apply voltage to the transmitter for

at least 5 minutes before starting calibration is begun and:

2. Remove the slotted screw that protects the two light emitting diodes and the calibration button.

3. Move the valve to the position (open or closed) in which an output signal of 4 mA is required and press the calibration button once. The red LED will light up constantly for 10 s.

4. When the red LED flashes, move the valve to the opposite position (open or closed) in which an output signal of 20 mA is required and press the calibration button for the second time. The red LED will light up constantly for 10 s.

5. When the red LED goes out, calibration is complete and AKS 45 is set for normal operation (see LED indication on page 4).

6. Replace slotted screw protecting LED's and calibrating button.

Note:If AKS 45 has been calibrated by moving the valve pressure pin manually between open and closed valve positions, it is not possible to open/close PM/PML/PMLX 65 - 125 and PMFH 500 completely with the manual spindle (accessory). PMFL must be calibrated during operation or before the valve is installed because AKS 45 and the manual spindle cannot be mounted together.

After calibration, AKS 45 will register the pressure pin travel by producing the following output signals:

- A variable output signal via terminals 2-3 of between 4 and 20 mA.

- A 24 V d.c. signal (with d.c. supply only) via terminals 2-4 (D1) when AKS 45 is in its 4 mA position, and via terminals 2-5 (D2) when AKS 45 is in its 20 mA position.
