1. Field of application

The MKA is a powerful function automatic to control and monitor combustion engines for sprinkler, emergency power, generator parallel and mains parallel systems. The automatic comes in different assembly variants. Modern parameter-based software is used to adapt to the different units and systems. This also can be carried out directly on the equipment display. Depending on expansion stage and variant assembly, analogue values can be connected as stan-dardised signals or direct (mains, generator voltage and generator currents). This allows the integra-tion of various protection and function units such as power control, power system protection, synchro-nisation and differential protection. Likewise, supply voltage and optional transmitters (pick-up) can be monitored. The mains and generator switch are controlled automatically or manually according to the selected operating mode. This also applies to starting and stopping the combustion engine. In using the widely adjustable times and counters, the automatic can be adapted easily and optimally to any requirement. The presetting of all parameters corresponds to DIN6280 or VDE0108. All parameters are stored zero voltage safe in a flash memory. Extensive internal and external (inputs for error messages) monitoring circles guarantee a safe opera-tion of the system, in which all electrical, mechanical operating equipment and system parts are monitored. From expansion stage 3 a generator/mains parallel operation is possible (overlapping or permanent parallel operation). Synchronisation and power system protection are integrated from this stage. The expansion stage 4 enables a direct power test with power control, current protection, differential protection etc.

2. Functioning

2.1. Generator programme

2.1.1. Isolation operation

In automatic operation the unit is started via the input "remote start" (term.B5). If the generator voltage

exceeds the limit value (TAB NO:2 LINE:5+6 COLUMN:3), the output “GLS ready“ (term.D25-26) is

closed. In order to switch on the GLS, the input “initial connection release/pilot” (free DE function no.

19) also must be set. If the input remains set even after the connection, the 50Hz control is enabled. If

the input is deactivated again after connection, the power control is enabled.

GLS is deselected by deactivating the input "remote start". If the 50Hz control is enabled, the GLS is

switched off immediately and the unit stops once the preset follow-up time expires (TAB NO:9

LINES:5 COLUMN:3). If, however, the power control is enabled and the power output is greater than

the limit value "unit charged", this is unloaded first. After unloading or after the "unloading time" is up,

the GLS is switched off.

2.1.2. Parallel operation

The selection and de-selection of GLS is made just as in isolated operation. Should the bus bar

voltage be available, the GLS is not switched on via the input “initial connection release/pilot”, but the

synchronisation is activated and the GLS is switched on via the syn pulse, which affects the output

“GLS On”.


2.1.3. Special Synchronising function

The selection and de-selection of GLS is made just as in isolated operation. The synchronisation de-

scribed in parallel operation is not in function with the “special synchronising function”. As soon as the

bus bar voltage is available and the GLS is closed, the syn pulse is displayed from the output “NLS on/

Syn pulse” (term.31-32). For giving the syn impulse while gen cb is open, the DI „release special syn

function“ has to be energized. The synchronisation is used as an independent function. The use of an

external synchronising device is not applicable.

2.1.4. Start up synchronising

Activating start up synchronising takes place via a pulse to the DI “RELEASE START UP SYN” and is

only effective for a specific adjustable time (START UP MAX. TIME / TAB-NO:9 LINE: 41 COLUMN:

3).

With the activation of the start up synchronisation the DO “GLS READY” is set and the connection of

the GLS takes place via the DI “GLS ON START UP SYN”. All modules with a closed GLS are started.

The voltage and the frequency of the alternators build up together and equalise with each other. If, in case of an activated start up synchronising, the machine does not start on the first try, then the DO “GLS READY” is deactivated and the GLS is switched off. If the machine only starts on the second or third try, then the connection with the synchronisation takes place. The Alarm “GEN UNDERVOLTAGE” is disabled during the start up synchronising.

2.1.5. Speed synchronising

In the options table (TAB-NO: 15 LINE: 16), the “SPEED SYNCHRONISING” must be activated.

The activation takes place via a pulse to the DI “RELEASE START UP SYN” and is only effective for a

specific adjustable time (START UP MAX. TIME / TAB NO: 9 ROW: 41 COLUMN: 3).

All modules are started simultaneously and a deexcitation of the alternators takes place. After expiry of

the deexcitation time (START UP DEEXIT. TIME / TAB NO: 9 ROW: 42 COLUMN: 3) the “GLS

READY” message is transmitted to the control centre. This takes over the connection of the GLS (DE

“GLS ON START UP SYN) in a voltage-free condition on the busbar. The excitation is switched on

again and together the voltage builds up. The frequency of the alternators equalise with each other.

If, in case of an activated start up synchronising, the machine does not start on the first try, then the

DO “AUTOMATIC OPERATION” is deactivated. The ALARM “GEN UNDERVOLTAGE” is disabled

during the start up synchronisation.

2.2. Mains/Generator programme

2.2.1. Changeover with gap

In automatic operation the unit is started via the input "remote start" (term.B5). If the generator voltage

has reached its operating value (TAB NO:2 LINE:5+6 COLUMN:3) the NLS is switched off and the

GLS switched on.

Speed reduction is effected after mains return and deactivation of the input “remote start”. For speed

reduction and stopping the unit, the speed reduction time and the follow-up time (TAB NO:9 LINE:5+8

COLUMN:3) must have expired.

8/75

2.2.2. Overlapping synchronising

2.2.2.1. Selection on remote start

The selection is made via the input “remote start”. If the generator voltage has reached its operating

value, the output “cancel locking” is set and synchronisation is triggered. If voltage and frequency are

within the preset limits, synchronous transfer takes place. During transfer both switches are closed for

approx. 0.2 seconds.

After deactivating the input “remote start”, once the speed reduction time is up, the output “cancel

locking” is set and synchronisation is triggered. If voltage and frequency are within the preset limits,

synchronous transfer takes place. During transfer both switches are closed for approx. 0.2 seconds.

After transfer the follow-up time expires and the unit stops.

2.2.2.2. Selection on mains power failure

In the event of power failure the unit starts. If the generator voltage has reached its operating value,

the NLS is switched off and the GLS switched on.

In the event of reset after the speed reduction time is up the output "cancel locking" is set and syn-

chronisation is triggered. If voltage and frequency are within the preset limits, synchronous transfer

takes place. During transfer both switches are closed for approx. 0.2 seconds. After the transfer the

follow-up time expires and the unit stops.

2.2.3. Mains parallel operation

2.2.3.1. Selection on remote start

The selection is made via the input “remote start”. If the generator voltage has reached its operating

value, the output “cancel locking” is set and synchronisation is triggered. If voltage and frequency are

within the preset limits, the GLS is switched on in the synchronous moment. Both switches are now on

and the output “parallel operation” (term.E27-28) is set. The power control is switched on.

After deactivating the input “remote start”, if the power is greater than the limit value "unit loaded" this

is first unloaded. Once unloaded or when the "unloading time" is up the GLS is switched off, the follow-

up time elapses and the unit stops.

2.2.3.2. Selection on mains power failure

In the event of mains power failure the unit starts. If the generator voltage has reached its operating

value, the NLS is switched off and the GLS switched on.

In the event of reset, once the speed reduction time has elapsed, the output "Cancel locking" is set

and synchronisation is triggers. If voltage and frequency are within the preset limits, transfer takes

place. During transfer both switches are closed for approx. 0.2 seconds. After transfer the follow-up

time elapses and the unit stops.

2.3. Operating hour counter

An operating hour counter is integrated into the automatic. The display of operating hours is found in

the measuring menu (point 4.2) in hours and minutes. The maximum time that can be counted is 1

million hours (114 years). The value cannot be reset and is also maintained in the event of power

failure.


2.4. Monitoring mains quality

Under and over voltage and under and over frequency of the mains voltage are monitored. The monitoring is only active when the mains voltage has reached its operating value (TAB NO: 2 LINE: 7 COLUMN: 3). If one of the alarm threshold values drops below or is exceeded, then the relevant malfunction alert is displayed after the malfunction alert delay. The LED for “Mains voltage available” blinks and the start procedure is initiated.

2.5. Start counter

The start is displayed in the measurement menu (point 4.2). The maximum number of counts that can

be done are 32000 starts. The value cannot be reset and is also kept in case of a power failure.

2.6. KWH counter

The kW hours are displayed in the measurement menu (point 4.2). The maximum value that can be displayed is 999.999.999 kWh. The counter increments are dependent on the configured value in the power values menu under “kWh PER PULSE” (TAB NO: 24 COLUMN: 9). The value cannot be reset and is also kept in case of a power failure.

2.7. Synchronoscope

The synchronoscope is automatically faded into the third row when the synchronisation is active. The phasing is displayed and the direction of the arrow indicates whether the revolutions must be reduced (<) or increased (>).

2.8. SD Card

2.8.1. Field of application

The display unit will be fitted with an SD Card. All MKA project data will be stored on this card. Current projects can be found in the display unit and on the SD Card. The SD Card enables you to copy the current program status easily from one automatic to another. Furthermore all modifications of parameters can be done without difficulties via the SD Card. On the card you will find the text file „STM.TXT“. This file contains the entire error message history.

2.8.2. Save data

The current data set can be found in file „STD_FILE.FMT“, in folder STD_DIR on the SD Card. With each restart of the automatic, or in case of a modification of the parameter program, project data are saved. During data storage the file „STD_FILE.FMT“ is renamed and saved again with date and time in the folder STD_DIR. Then the file „STD_FILE.FMT“ will be generated again with the current data.

2.8.3. Load data

To load the current data set the key(+) has to be pressed when turning on the power. If an older program status has to be loaded the relevant file on the SD Card has to be renamed on the PC to „STD_FILE.FMT“. Then this file can be loaded with the key(+) pressed when power is turned on. In order to reset the automatic the (+)key and the (ESC)key have to be pressed at the same time when turning on the power.

11 Function key which can be parameterised to a freely allocable output. The function can be selected as key or switch. The LED arranged in the key field can be parameterised to a freely allocable input and must be activated externally.

12 See key 11 13 See key 11 14 Acknowledging and resetting an error message. The yellow LED indicates a warning error

message. When the error message is switched off the yellow and red LED’s are illuminated. By pressing the key for the first time the LED’s go from flashlight to constant light. The horn is switched off. If the error message is corrected, pressing the key for the second time results in the LED's going out and the fault indicator texts disappear in the display. If the error message is not corrected, the second press of the key results in the LED's flashing again and the horn is set.

15 The LED function can be parameterised e.g. to display an error message. 16 With the selection of the operating mode OFF the generator switch is switched off and the

unit is stopped. The key “0” has priority over all other keys. Furthermore a general mains switch release is accorded and when there is mains power available this is switched off.

17 The unit can be started in the operating mode MAN with the key "Start". The output DA03 (term. B21/22) is active as long as the push buttons is pressed and the input “ignition speed” (term. A02) is not energized.

18 By selecting the operation mode test the gen set will be started and supervised automatically. The gen set runs without load. Mains and gen cb push buttons are active for manual on/off switching the cb’s. In case of a mains failure while test mode automatical emergency operation follows. Change back to mains supply after mains returns follows manually or by selecting the operation mode auto.

19 In the operating mode HAND manual operation is pre-selected. The unit can be started using the key "Start". Once started the function of the key changes and appears on the display as “OFF”. The unit can now be stopped again using this key. In this operation mode the control does not respond to a power failure. The switches have to be activated manually using the mains and generator switch keys.

20 E.g. NG control: With the selection of operating mode AUTOMATIC the unit is made ready for automatic start. In the event of power failure it leads to automatic replacement power operation. The unit is automatically started, the mains switch release is cancelled and the generator switch release is accorded. The consumer loads are supplied by the generator. In the case of mains return (restart), once the time stages have elapsed, the loads are auto-matically set to the mains. The unit is stopped after one cooling run. For automatic start re-mote start input can also be used, e.g. to achieve load test or top load operation with or with-out synchronisation.

21 The LED function can be parameterised e.g. to display an error message. 22 LED for unit operation. Together with the operating message “MOTOR RUNNING” the LED

also lights up. Once the unit has ground to a halt and the stopping time is up, the operating message “MOTOR STANDING” appears and the LED goes out.

23 The LED function can be parameterised, e.g. to display an error message. 24 See key 25 25 Keys for generator switch OFF and ON. The LED’s in the key fields are controlled via the

switch feedback signals. The keys are only enabled in manual and test operation with the available generator power. By means of software the generator switch release and mains switch release are locked. The generator and mains switches have to be locked externally using breakers. The internal locking is cancelled during synchronisation.

26 The LED function can be parameterised, e.g. to display an error message. 27 See key 28 28 Keys for mains switch OFF and ON. The LED’s in the key fields are controlled via the switch

feedback signals. These keys are only enabled in manual and test operation. Mains switch release and generator switch release are locked using software. These should also be locked externally using breakers. The internal locking is cancelled by introducing synchronisation.

29 The LED function can be parameterised, e.g. to display an error message. 30 LED available for mains voltage. 31 LED available for generator voltage.

carried out externally, a 0 – 10VDC signal has to be set on terminals F15 (-) and F16 (+). Evaluation of the signal can be scaled. By default the 0 – 10VDC correspond to a nominal value of 0 – 125%.

4.3.2. Mains Im./Ex. Contr.

The mains im/export controller regulates the generator power during mains parallel operation until reaching the preadjusted value. While adjusting the setpoint it is important if the power shall be exported to or imported from mains. For export the setpoint has to be negative, for import positive.

Internal preadjusting is done by using the buttons 7 and 8. The adjusted value will be maintained also

if 24V voltage supply fails. The adjusting range of the mains set point can be limited (Table:23; Line:5; Column: 3+4). For actual mains value indication the 0 – 10VDC measuring transducer signal must be connected to the terminals F13(-) and F(+). The analogue input can be scaled and has to be adapted to the measuring transducer(Table:14; Line:5; Column:8+9). Example: For an im/export regulation a measuring transducer is needed p.e. with an output from 0 – 10VDC for a power range from –500KW (export) to +500KW (import). All measuring values will be indicated in KW. To activate the regulation during mains parallel operation the DI “mains im/export controller” has to be energized.

4.3.3. Cos Phi Contr.

The Cos Phi contr. regulates the reactive power factor during mains parallel operation until

reaching the preadjusted value. Preadjusting is done by using the buttons 7 and 8. The adjusted

value will be maintained also if 24V voltage supply fails. The setpoint can be set to the current

actual value, as shown in line 2, with the key “ENTER“ 10. Further adjusting will then be done with

the buttons 7 and 8. Regulation is done via adjustment pulses at the outputs „Voltage higher“

respectively „Voltage lower“, which have to be parameterised to two free digital outputs.

The automatic is delivered for 24VDC voltage supply as standard. It is therefore also possible to build the automatic as 12VDC variant. Please specify this when ordering. The bus connection to MKA must be shielded. The maximum output length should not exceed 500m. Furthermore an output resistance of 50 Ohm should not be exceeded. A PC can be connected with serial interface via the parameterisation interface (SUB-D 9 pole jack). The programming cable is a standard 1:1 cable. By using the appropriate software it is easy to set the parameters in the MKA. The interface can also be accepted for coupling to an SPS control. 10 pole. Flat cable connectors can be connected to up to four expansion pads. There are 16 LED’s on each pad. The function of the LED can be parameterised. Error messages or operating signals can be selected. A 120 Ohm load resistor has to be connected to the term. 11/12 for the BUS.

7. Protection functions

7.1. Mains protection


The mains protection function of the MKA serves to monitor the generator for voltage, frequency and vector transfer. The limit values are adaptable to each application case. The device shall be used for 3 and 4 conductor network configurations. This is to be specified in “TAB NO:4 LINE:1 COLUMN:16". The extremely fast response times enable a unit to be separated from the network in mains parallel operation in the event of failure, in order to avoid a feedback or an asynchronous concurrence of two networks. Furthermore the MKA meets the mains protection conditions required by the VDEW.

7.1.2. Functioning

The voltage metering is a true effective value measuring. Every three measuring circuits are metered simultaneously. For the display of voltages and frequencies the measuring voltage must be between the outer conductors > 45VAC. It leads to a triggering, so the output relay (term. F17/18) is activated. The relay output is to be coded with a jumper on the circuit board for break contact (standard) or open contact. The triggering of the mains protection has no influence on the function of MKA whatsoever. If an error message is to be signalled on the display, the mains protection function is to be linked with an error message input.


For correct adaptation to each application case parameter setting is necessary. The action values have to be checked and if need be, adapted to the system (TAB NO:16).

7.2. Current protection


The current protection function of MKA monitors the current in three-phase networks. There are two configurable limit values available with magnetic disconnection reaction and a limit value with heat disconnection reaction available. There is a delay time selectable for each magnetic limit value (TAB NO:6 LINE:55,56,57 COLUMN:4). Switching reaction can be coded to working or closed current. The current measuring circuits and supply voltage are galvanically-isolated (DC) among each other and against electronic measuring equipment. For this reason direct current metering is possible even without current transformer in a nominal current range up to 5A. An influence e.g. by earth loop is excluded. It is particularly worth mentioning that the heat limit value (STM57) can work as delayed overload re-lease. This reaction is based on the heat-time overload release of motor protection switches. The MKA meets the standards VDE 0108 with 110 % nominal current within a 12 hour interval. The current-de-pendent overload trigger can be disengaged (TAB NO:13 LINE:1 COLUMN:7) When placing an order it should be specified whether the MKA is to be used for a 1A or 5A circuit.

7.2.2. Functioning

Current metering takes place as simultaneous 3-phase sampling and is a true effective value measuring. If the current in one of the three phases is greater than the pre-selected limit value (TAB NO:13), the activation delay time (TAB NO:13) starts to run. Once the delay time is up the appropriate error message is integrated into the display. In addition it is possible to link a digital output (TAB NO:11) with the error message function. If the limit value falls short again, the regulating notch without hysteresis tilts back into idle position after approx. 2 seconds.

(nom) with 110% at 3600 s=1 hour is used and 400 % nenn (nom) at 3 s.

7.3. Diff protection


The differential protection function of MKA is to be used to protect three-phase rotary current genera-tors or three-phase rotary current synchronous and asynchronous motors. It senses the residual cur-rents within the protected zone (fig. 1), triggers when reaching the preset limit values (TAB NO 12) and the corresponding error messages are displayed. When placing an order, specify whether the MKA is to be used for a 1A or 5A circuit.

48/75

7.3.2. Functioning

The differential protection measuring is the comparison of currents between generator star point and the outflow of generator or the supply in the switching gear. The sum of all currents must be zero.

Fig. 2: Metering principle

Three transformer circuits capture the current in the star point of the generator (internal electric cir-cuit), three other transformer circuits are to be arranged by the customer and capture the consumer current (external electric circuit). The measuring in the six current paths in made as simultaneous sampling of all six measuring circuits with 16 samplings per cycle and path. For each current value the real effective value is calculated and evaluated once a cycle is up. The minimal disconnection delay amounts to approx. 130 ms. There are two limit values available with parameter setting options. A delay time can be selected for every limit value (TAB NO:12) The switching reaction can be coded to working or closed current (TAB NO: 6 LINE:58,59). In order to avoid accidental triggering e.g. starting large electrical drives, the triggering can be disabled for a set time (TAB NO:12 LINE:1 COLUMN:9) If the residual current in one of the three phases is greater than the pre-selected limit value (TAB NO:12), the delay time (TAB NO:12) starts to run. Once the delay time is up the appropriate error message is integrated into the display. In addition it is possible to link a digital output (TAB NO:11) to the error message function. If the limit value falls short again, it automatically resets. The following values are used for measuring and switch off.

The difference between internal and external current is calculated from the instantaneous values of the currents, so that it is also possible to identify and evaluate a phase difference.

7.3.4. Infliction point

During operation, once the sampling interval is up, the measured values are compared with the preset limit values for pre-warning and cut-out. Upon reaching the limit values the corresponding error mes-sages is displayed. The infliction point (TAB NO:12) can be set in the range from 50% to 500%. If the phase current ex-ceeds the preset infliction point, the pre-warning and cut-out characteristic is increased by 10 % per 100 % phase current.

8. Special functions

8.1. Synchronising


Synchronisation of MKA is used for automatic parallel switching of three-phase rotary current genera-tors or to another three-phase rotary current system. Voltage and frequency are therefore adapted. Generator isolated operation is controlled to a pre-specified basic frequency or voltage.

8.1.2. Functioning

Using differential amplifiers the voltage and the frequency are captured by two three-phase rotary cur-rent supply networks. Measuring for synchronisation is made between L1 and L2. During operation the voltages and the averaged frequencies are continually display in text. If synchronising process is introduce, the corresponding output for switch "ready" is set (NLS ready D29/30 or GLS ready D25/26). The frequency adjustment pulse (F+ and F-) are specified for the speed governor of the unit to the terminals F9/10 and F11/12. In addition it is possible to use two configurable outputs with the function for the voltage adjustment pulse (U+ and U-). The syn pulse is given on the corresponding switch (NLS On D31/32 or GLS On D27/28). If the synchronisation is not made within the preset time (TAB NO:6 LINE:43 COLUMN:4) the error message „SYN TIME TOO LONG“ (STM43) appears.

8.3. Power control


In mains parallel operation or generator parallel operation the power control is used. In the MKA a comparison is made of the actual and nominal power output. The nominal value specification can be pre-selected externally using a 0–10VDC input (term. F16+/15-) or on the operator unit OP2. An overview of how the specification is set on the operator unit is found under point 4.3 in the control menu. The preset values are also kept after a power failure. In mains parallel operation the power control is always enabled. In generator parallel operation the configurable digital input "initial connection release / pilot" (function no. 19) is used to select whether the power control or the 50Hz control (pilot) is enabled after switching on the GLS. In generator switch gear the GLS needs the initial connection release for connection onto a dead bus bar. If the input continues to remain set the 50Hz control affects the unit. If the input is deactivated again after connection, the power control affects the unit.

8.4. Performance data (output values)


The limit value “unit loaded” (TAB NO:24 LINE:1 COLUMN: 3) specifies the output value, which, when exceeded, on deselecting the GLS the MKA will unload the unit with the power control. If unloading does not take place after a parameterised time (TAB NO:9 LINE:15 COLUMN:3) the GLS will be switched off under load. There are two parameter configurable limit values available each for reverse power and overload (TAB NO:24). There is a delay time selectable for each limit value (TAB NO:6 LINE:60-64 COLUMN:4). Switching reaction can be coded to working or closed current. If the limit values are exceeded and the delay time is up, the corresponding error message is displayed. In the event of an unbalanced load the cable outputs are compared. Should there be a differing load (strain) this may not be exceed the preset limit value. If the limit value is exceeded and the delay time is up, the corresponding error message is displayed. In order to display the active energy on the counter, the extent of active energy must be specified until the MKA counts, in order to release a pulse. The release of pulses must be parameterised on an out-put relay. If the activity has reached the preset limit value, a pulse is emitted. The pulse duration is 1 s.

12. Alarm settings

12.1. Alarm coding


Error messages 1 - 32 are external and can be connected to the corresponding inputs. The fault indi-cator text as well as the alarm system can be parameterised (TAB NO:5 LINE:1-19). Error messages 33 – 64 are internal. The text for these cannot be altered because a fixed function is assigned to them. The alarm system can be parameterised. A description of the internal error messages is under point 10.2 “Digital Outputs" under the function number 65 – 96.


For correct adaptation to each application case parameter setting is necessary (TAB NO:5 LINE:1-64). The alarm system has individual parameter options for each STM.

12.2. Alarm limit values


For specific error messages it is important to enter the limit values for the corresponding application case. In the table “limit values_STM” there are multiple parameters available, which can each be modi-fied.


For correct adaptation to each application case parameter setting is necessary (TAB NO:3). If the limit value is exceeded or falls short and the error message delay time is up, the STM is shown on the dis-play and the functions which are determined when the parameters are set, are carried out.
