AMF (no back synchronisation)

Auto mode description The unit automatically starts the gen-set and switches to generator supply at a mains failure

after an adjustable delay time. It is possible to adjust the unit to change to gen-set operation in two different ways.

1. The mains breaker will be opened at gen-set start-up.

2. The mains breaker will remain closed, until the gen-set is running, and the gen-set voltage and frequency is OK.

In both cases, the generator breaker will be closed, when the generator voltage and frequency is OK, and the mains breaker is open.

When the mains returns, the unit will switch back to mains supply and cool down and stop the gen-set. The switching back to mains supply is done without back synchronisation, when the adjusted ‘mains OK delay’ has expired.

See mode overview in chapter 6 on page 61 for short description.

The flowcharts below illustrate the full functionality of the mentioned gen-set modes.

This section about applications is to be used for reference using the particular gen-set mode as starting point. It is not suitable for reading from beginning to end.

AMF (with back synchronisation)

Auto mode description The unit automatically starts the gen-set and switches to generator supply at a mains failure

after an adjustable delay time. It is possible to adjust the unit to change to gen-set operation in two different ways:

1. The mains breaker will be opened at gen-set start-up.

2. The mains breaker will remain closed until the gen-set is running and the gen-set voltage and frequency is OK.

In both cases, the generator breaker will be closed, when the generator voltage and frequency is OK, and the mains breaker is open.

When the mains returns, the unit will synchronise the mains breaker to the busbar, when the ‘mains OK delay’ has expired. Then the gen-set cools down and stops.

Semi-auto description When the generator breaker is closed and the mains breaker is opened, the unit will use the

nominal frequency as the setpoint for the speed governor. If AVR control (option D1) is selected, the nominal voltage is used as the setpoint.

When the generator is paralleled to the mains, the governor regulation will be active afterwards. It will use the setting ‘generator minimum load as the setpoint’ (menu 6523). If AVR control (option D1) is selected, then the setpoint will be the adjusted power factor (6550 Fixed power setpoint).

Island operation

Auto mode description The unit automatically starts the gen-set and closes the generator breaker at a digital start

command. When the stop command is given, the generator breaker is tripped, and the gen-set will be stopped after a cooling-down period. The start and stop commands are used by activating and deactivating a digital input. If the time dependent start/stop commands are to be used, then the auto mode must also be used. In this case, the digital input ‘auto start/stop’ cannot

be used.

Fixed power/base load

Auto mode description The unit automatically starts the gen-set and synchronises to the mains, when the digital input

‘auto start/stop’ is activated. After the generator breaker closure, the unit ramps up the load to the setpoint level. When the stop command is given, the gen-set is deloaded and stopped after the cooling-down period. The start and stop commands are used by activating and deactivating a digital input. If the time dependent start/stop commands are to be used, then the auto mode must also be used. In this case, the digital input ‘auto start/stop’ cannot

be used.

Diagram, fixed power - principle

Semi-auto mode description When the generator breaker is closed and the mains breaker is opened, the unit will use the

nominal frequency as the setpoint for the speed governor. If AVR control (option D1) is selected, the nominal voltage is used as setpoint.

When the generator is paralleled to the mains, the generator power will be increased to the fixed power setpoint (6550 Fixed power setpoint). If AVR control (option D1) is selected, then the setpoint will be the adjusted power factor (6550 Fixed power setpoint).

Peak shaving

Auto mode description The gen-set will start at a predefined mains import level and run at a fixed minimum load, e.g.

10%. When the mains import increases above the maximum mains import setpoint, the gen-set will supply the extra load in order to maintain the mains import at the maximum import level.

When the load drops below the max. mains import setpoint, the gen-set will run at min. load again. When the mains import decreases below the stop setpoint, the gen-set will cool down and stop.

A 4-20mA transducer is used for indication of the power imported from the mains.

Semi-auto mode description When the generator breaker is closed and the mains breaker is opened, the unit will use the

nominal frequency as setpoint for the speed governor. If AVR control (option D1) is selected, the nominal voltage is used as setpoint.

When the generator is paralleled to the mains, the generator will be controlled according to the peak shaving setpoint. So the maximum mains import will not be exceeded in spite of the semiauto mode. If AVR control (option D1) is selected, the setpoint is the adjusted power factor (6550 Fixed power setpoint).

Test mode description

Block mode description

Load take over

Auto mode description Back synchronising ON

The purpose of the load take over mode is to transfer the load imported from the mains to the gen-set for operation on generator supply only.

When the start command is given, the gen-set will start and synchronise the generator breaker to the busbar that is being supplied by the mains. When the generator breaker is closed, the imported load is decreased (the power is being transferred to the gen-set), until the load is at the open breaker point. Then the mains breaker opens.

When the stop command is given, the mains breaker is synchronised to the busbar and after closure the gen-set is deloaded, cooled down and stopped.

See general semi-auto mode description on page 19.

A 4-20mA transducer is used for indication of the power imported from the mains.

Diagram, load take over - example

Back synchronising OFF When the start command is given, the gen-set will start. When the frequency and voltage is OK, the mains breaker is opened and the generator breaker is closed. Now the generator supplies the load, until the stop command is given. Then the generator breaker opens and the mains breaker closes. The gen-set cools down and stops.

A 4-20mA transducer is used for indication of the power imported from the mains.

Semi-auto mode When the generator breaker is closed, and the mains breaker is opened, the unit will use the

nominal frequency as setpoint for the speed governor. If AVR control (option D1) is selected, the nominal voltage is used as setpoint.

When the generator is paralleled to the mains, it will be controlled, so the imported power from the mains will be kept at 0 kW. If AVR control (option D1) is selected, the setpoint is the adjusted power factor (6550 Fixed power setpoint).

The load take over mode can be combined with the short time parallel. In that case, the generator and the mains breakers will never be closed at the same time for a longer period than the adjusted ‘short time parallel’ time.

If the imported load is higher than the nominal gen-set an alarm appears, and the load take over sequence is paused.

If the imported load is higher than the nominal gen-set power, an alarm appears and the load take over sequence is paused.

Mains power export (fixed power to mains)

Auto mode description The mains power export mode can be used to maintain a constant level of power through the

mains breaker. The power can be exported to the mains or imported from the mains, but always at a constant level.

The gen-set starts as a result of a digital start command. It synchronises to the mains and will start to export power to the mains. The amount of power exported or imported will be kept at a fixed level regardless of the load on the busbar (the factory).

The stop command will cause the gen-set to deload and trip the generator breaker. Afterwards, it will cool down and stop.

A 4-20mA transducer is used for indication of the power exported from the mains. The example below shows a situation where the setpoint is adjusted to exporting power to the mains.

Semi-auto description When the generator breaker is closed and the mains breaker is opened, the unit will use the

nominal frequency as setpoint for the speed governor. If AVR control (option D1) is selected the nominal voltage is used as setpoint.

When the generator is paralleled to the mains, it will be controlled according to the mains power export setpoint. If AVR control (option D1) is selected, the setpoint is the adjusted power factor (6550 Fixed power setpoint).

Block mode description

General semi-auto mode description

The unit can be operated in semi-automatic mode. Semi-auto means that the unit will not initiate any sequences automatically, as is the case with the auto mode. It will only initiate sequences, if external signals are given.

An external signal may be given in three ways:

1. Push-buttons on the display are used

2. Digital inputs are used

3. Modbus command.

Please notice that the set point of the mains power export can be adjusted to 0 kW. This means that the gen-set will be parallel to the mains but no power import or export.

See general semi-auto mode description on page 19.

See general test mode description valid for all gen-set modes on page 20.

See general manual mode description valid for all gen-set modes on page 21.

See general block mode description valid for all gen-set modes on page 21.

The standard AGC is only equipped with a limited number of digital inputs, please refer to page 95 in this document and the data sheet for additional information about availability.

AGC Designer’s Reference Handbook

DEIF A/S Page 20 of 168

When the gen-set is running in semi-auto mode, the unit will control the speed governor and the AVR, if option D1 is selected.

The following sequences can be activated in semi-auto:

Command Description Comment

Start The start sequence is initiated and continues until the gen-

set starts or the maximum number of start attempts has been reached. The frequency (and voltage) will be regulated to make the GB ready to close.

Stop The gen-set will be stopped. After disappearance of the

running signal, the stop sequence will continue to be active in the ‘extended stop time’ period. The gen-set is stopped without cooling-down time.

Close GB The unit will close the generator breaker, if the mains

breaker is open, synchronise and close the generator breaker, if the mains breaker is closed.

When AMF mode is selected, the unit will not regulate after breaker closure.

Open GB The unit will ramp down and open the generator breaker at

the breaker open point, if the mains breaker is closed. The unit will open the generator breaker instantly, if the mains breaker is open or the gen-set mode is island mode.

Close MB The unit will close the mains breaker, if the generator

breaker is open, synchronise and close the mains breaker,

if the generator breaker is closed. Open MB The unit opens the mains breaker instantly. Manual GOV UP

The regulator is deactivated and the governor output is

activated as long as the GOV input is ON. Manual GOV DOWN

The regulator is deactivated and the governor output is

activated as long as the GOV input is ON. Manual AVR UP

The regulator is deactivated and the governor output is

activated as long as the AVR input is ON.

Option D1 is

required. Manual AVR DOWN

The regulator is deactivated and the governor output is activated as long as the AVR input is ON.

Option D1 is

required.

General test mode description

The test mode function is activated by selecting test with the MODE push-button on the display or by activating a digital input, if one of them is configured to ‘test’. The test mode will only test synchronising, if the ‘Sync. to mains’ function is enabled. If this is the case, the gen-set will start, and the unit will synchronise and close the generator breaker to let the gen-set run in parallel, until the test time expires. If the ‘Sync. to mains’ function is not activated, then the gen-set will start and run at the nominal frequency with the generator breaker open.

It is possible to manually increase and decrease the speed/voltage when semiauto is selected. When the digital up/down input is activated, then the regulator is deactivated as long as the manual up/down inputs are activated.

Manual voltage control is option dependent (option D1).

AGC Designer’s Reference Handbook

DEIF A/S Page 21 of 168

The settings for the test function are set up in menu 6540 Test running

• Setpoint: Load setpoint when paralleling to mains.

• Timer: Engine run time during the test period

• Return: When the test is completed, the unit will return to the selected mode

(semi-auto or auto).

General manual mode description

When manual mode is selected, the gen-set can be controlled with digital inputs. The following commands are possible:

Command Comment

Start Gen-set starts. Stop Gen-set opens GB and stops

without cooling-down.

Manual increase speed Unit gives increase signal to

speed governor.

Manual decrease speed Unit gives decrease signal to

speed governor.

Manual increase voltage Unit gives increase signal to

the AVR. (Option D1).

Manual decrease voltage Unit gives decrease signal to

the AVR. (Option D1).

General block mode description

When the block mode is selected, the unit is locked for certain actions. This means that it cannot start the gen-set or perform any breaker operations.

To change the running mode from the display, the user will be asked for a password, before the change can be made. It is not possible to select ‘block mode’, when running feedback is present.

Short time parallel is ignored in test mode.

Test mode cannot be used, if the gen-set is in island operation (gen-set mode selected to island mode).

It is not possible to open and close the generator breaker or the mains breaker in manual mode.

It is necessary to configure the digital inputs through the PC utility software to use the manual commands. The number of configurable digital inputs is option dependent.

MAN mode cannot be selected, when AUTO mode is selected. To go from AUTO to MAN it is necessary to go to SEMI-AUTO to make MAN available.

AGC Designer’s Reference Handbook

DEIF A/S Page 22 of 168

The purpose of the block mode is to make sure that the gen-set does not start for instance during maintenance work.

If the digital inputs are used to change the mode, then it is important to know that the input configured to block mode is a constant signal. So, when it is ON the unit is in a blocked state, and when it is OFF, it returns to the mode it was in before block mode was selected.

Alarms are not influenced by block mode selection.

The gen-set can be started from the local engine control panel, if such is installed. Therefore, DEIF recommends to avoid local cranking and starting of the gen-set.

If block mode is selected using the display after the digital block input is activated, the AGC will stay in block mode after the block input is deactivated. The block mode must now be changed using the display. The block mode can only be changed locally by display or digital input.

Before the running mode is changed it is important to check that persons are clear of the gen-set and that the gen-set is ready for operation.

Sequences

The following contains information about the sequences of the engine, the generator breaker and, if installed, the mains breaker. These sequences are automatically initiated if the auto mode is selected, or if the commands are selected in the semi-auto mode.

In the semi-auto mode the selected sequence is the only sequence initiated (e.g. press the START push-button: The engine will start, but no subsequent synchronising is initiated).

The following sequences will be illustrated below:

• START sequence

• STOP sequence

• Breaker sequences

If island operation is selected, the digital input ‘MB closed’ must NOT be activated with a 12/24 volt input signal. A ‘mains breaker failure’ will occur, if the wiring of the mains breaker feedback inputs is wrong.

START sequence

The drawings illustrate the start sequences of the gen-set.

DEIF A/S Page 42 of 168

4 different types of running feedback can be used to detect if the motor is running. Refer to menu 4300 for selection of the running feedback type.

The running detection is made with a built-in safety routine. The running feedback selected in menu 4300 is the primary feedback. At all times all the types of running feedback is used for running detection. If for some reason the primary choice is not detecting any running feedback, the starter relay will stay activated for additionally 1 second. If a running feedback is detected based on one of the secondary choices, the gen-set will start. This way the gen-set will still be functional even though a tacho sensor is damaged or dirty.

As soon as the gen-set is running, no matter if the gen-set is started based on the primary or secondary feedback, the running detection will be made based on all 4 types.

The sequence is shown in the diagram below.

gen-set is running.

If the tacho input is to be used to remove the starter, it has to be set up in menu

6161. If the digital input is to be used as running feedback, then terminal 115 has to be used.

The only protections that can stop the gen-set/interrupt the start sequence when the ‘fire pump’ input is activated, are the digital input ‘emergency stop’ and the tacho alarm ‘overspeed 2’. Both of these must have the fail class ‘shut down’.

Mode overview

The unit has four different running modes and one block mode. For detailed information see page 11.

Auto

In auto mode the unit will operate automatically, and the operator cannot initiate any sequences manually.

Semi-auto

In semi-auto mode the operator has to initiate all sequences. This can be done via the pushbutton functions, Modbus commands or digital inputs. When started in semi-automatic mode, the gen-set will run at nominal values.

Test

AGC Designer’s Reference Handbook

DEIF A/S Page 63 of 168

The test sequence will start when the test mode is selected.

Manual

When manual mode is selected, the binary increase/decrease inputs can be used (if they have been configured) as well as the start and stop push-buttons. When starting in manual mode, the gen-set will start without any subsequent regulation.

Block

When the block mode is selected, the unit is not able to initiate any sequences, e.g. the start sequence.

Mode selection

The following drawings illustrate how the mode selection is carried out.

Pushing the MODE push-button will change the displayed text. After pushing ‘MODE’, the fourth display line indicates the selectable modes. In the third display line, the underscored (fourth line) selection will be displayed.

Two possibilities are now available:

If ‘BACK’ is pushed, the display returns to the original text without changing the mode.

Password

The unit includes three password levels. All levels can be adjusted in the PC software.

Available password levels:

Access Password level Factory setting

Customer Service Master

Customer 2000 X Service 2001 X X Master 2002 X X X

A parameter cannot be entered with a too low ranking password. But the settings can be displayed without password entry.

Each parameter can be protected at a specific password level. To do so, the PC utility software must be used. Enter the parameter to be configured and select the correct password level.

AGC Designer’s Reference Handbook

DEIF A/S Page 65 of 168

Parameter access

To get access to adjust the parameters, the password level must be entered:

If the password level is not entered, it is not possible to enter the parameters.

The customer password can be changed in menu 9116 page 167. The service password can be changed in menu 9117 page 167. The master password can be changed in menu 9118 page 167.

The factory passwords must be changed, if the operator of the gen-set is not allowed to change the parameters.

It is not possible to change the password at a higher level than the password entered.

6. Additional functions

This chapter describes the additional functions.

Start functions

The unit will start the gen-set when the start command is given. The start sequence is deactivated when the remove starter event occurs or when the running feedback is present.

The reason for having two possibilities to deactivate the start relay is to be able to delay the alarms with run status.

If it is not possible to activate the run status alarms at low revolutions, the remove starter function must be used.

An example of a critical alarm is the oil pressure alarm. Normally, it is configured according to the shutdown fail class. But if the starter motor has to disengage at 400 RPM, and the oil pressure does not reach a level above the shutdown setpoint before 600 RPM, then, obviously, the gen-set would shut down, if the specific alarm was activated at the preset 400 RPM. In that case, the running feedback must be activated at a higher number of revolutions than 600 RPM.

Digital feedbacks

If an external running relay is installed, then the digital control inputs for running detection or remove starter can be used.

Running feedback When the digital running feedback is active, the start relay is deactivated and the starter motor

will be disengaged.

Remove starter When the digital remove starter input is present, the start relay is deactivated and the starter

motor will be disengaged.

The diagram illustrates how the remove starter input (terminal 118) is activated, when the engine has reached its firing speed. At the running speed the digital running feedback is activated.

DEIF A/S Page 69 of 168

Breaker spring load time

If the breaker needs time to reload the spring after it has opened, then the AGC can take this delay into account. This can be controlled through timers in the AGC or through digital feedbacks from the breaker, depending on the breaker type.

Principle

The diagram shows an example where a single AGC in island mode is controlled by the AUTO start/stop input.

This is what happens: When the AUTO start/stop input deactivates, the GB opens. The AUTO start/stop is reactivated immediately after the GB has opened, e.g. by the operator through a switch in the switchboard. However, the AGC waits a while before it issues the close signal again, because the spring load time must expire (or the digital input must be activated - not shown in this example). Then the AGC issues the close signal.

Digital input

This can be used e.g. when the breaker is able to send a feedback to the AGC when its spring is reloaded.

There is one input for the generator breaker and one for the mains breaker. The input configuration is done through the PC utility software. The names of the inputs are ‘GB spring loaded’ and ‘MB spring loaded’. In the example below they are configured to terminal 91 and 92.

AGC Designer’s Reference Handbook

DEIF A/S Page 70 of 168

When the feedback is not activated, the breaker cannot close. The LED above the breaker symbol will be flashing (yellow), and the AGC will not attempt to issue a close signal before the spring load feedback is on.

Timer-controlled

On breakers where no feedback can be issued when the spring is in loaded position, timer settings can be used instead. There are timers for all breakers that can be controlled by the AGC, i.e. the generator breaker (menu 6252), the mains breaker (menu 6615) and the tie breaker (option G5, menu 7632).

When the timers are counting, then the remaining time is shown in the display, the LED above the breaker symbol will be flashing (yellow) and the AGC will not attempt to issue a close signal before the timer has expired.

Alarm inhibit

The purpose of the alarm inhibit function is to avoid nuisance alarms when the gen-set is in a controlled operational state (stop). For example it is not necessary to have the low lubricating oil pressure alarm displayed when the gen-set stops.

Four possibilities exist for the alarm inhibit functionality:

1. Digital input 23 can be used.

2. The alarms can be given

RUN status.

3. Selectable alarms can be given

Parallel status.

4. Selectable alarms can be ‘custom inhibit’ by using a configurable input in the utility SW.

Digital input 23

The functionality of the alarm inhibit input is indicated in the table below:

The inhibit LED on the unit and on the display will activate when the voltage is below 30% of the nominal voltage.

On the AGC mains unit (option G5) the spring load feedback from the tie breaker can be connected instead of the GB spring load feedback.

Custom inhibit input

The custom inhibit function is made to give the user a possibility to decide which protections should be inhibited when an input is activated.

To activate the custom inhibit function two things are needed:

1. Configure an input in the input settings in the utility SW.

2. Enable the function as shown in the dialog box below.

If an alarm is configured to activate a limit relay, the relay will activate in spite of the fact that the inhibit input is ON.

If the protection is configured to ‘RUN’ or ‘PARALLEL’ the custom inhibit will overrule these functions, if the input is active after the conditions for ‘RUN’ or ‘PARALLEL’ have been removed.

Function inputs such as running feedback, remote start or access lock are never inhibited. Only alarm inputs can be inhibited.

DEIF A/S Page 78 of 168

Access lock

The digital input number 114 is preconfigured to the function ‘access lock’. The purpose of access lock is to deny the operator the possibility to configure the unit parameters and change the running modes.

Access lock will typically be activated from a key switch installed behind the door of the switchboard cabinet.

Short-time parallel

The purpose of the short time parallel function is to be able to define a maximum paralleling time between the generator and the mains supply.

The function is typically used, if there are local requirements to maximum allowed paralleling time.

The short time paralleling function is only available in the automatic mains failure and load take over gen-set modes.

AGC Designer’s Reference Handbook

DEIF A/S Page 80 of 168

The diagram shows that when the generator breaker is synchronised, the mains breaker will be opened automatically after a time delay (t). Later the mains breaker is synchronised, and the generator breaker is opened after the time delay (t).

The time delay is measured in seconds and can be adjusted from 0.10 to 99.90 seconds.

The short time parallel function is set up in

2700 Short time paralleling

Digital mains breaker control

The unit will normally execute the automatic mains failure sequence based on the settings adjusted in the system setup. Besides these settings it is possible to configure a digital input that can be used to control the mains return sequence. This input is the ‘mains OK’ input. The purpose of this function is to let an external device or an operator control the mains return sequence. The external device can e.g. be a PLC.

The flowchart below shows that if the input is configured, it needs to be

deactivated in order to

initiate the mains return sequence. The load will continue on generator supply, if the input is still activated.

The mains OK delay is not used at all when the ‘mains OK’ input is configured.

The same time delay is used for both generator and mains breaker synchronisation.

If the function is used in a Power Management (option G5) application, then the short time paralleling will occur between the mains breaker and the tie breaker on the AGC mains.

The time delay typed in the set point is a maximum time. This means that if 0.10 seconds are used, the two breakers will never be closed at the same time for a longer delay than the set point.

AGC Designer’s Reference Handbook

DEIF A/S Page 81 of 168

Time dependent start/stop

The purpose of the time dependent start/stop function is to be able to start and stop the gen-set automatically at specific times each weekday or certain weekdays. If auto mode is activated, this function is available in island operation, load take over, mains power export and fixed power operation. Up to 8 commands can be used for either start or stop. The settings are set up through the PC utility software. Each command can be set for the following time periods:

• Individual days (MO, TU, WE, TH, FR, SA, SU)

• MO, TU, WE, TH

• MO, TU, WE, TH, FR

• MO, TU, WE, TH, FR, SA, SU

Select the correct relay number in output A and output B and enable the function. Change the relay function to limit in the I/O menu. Then the relay will activate, but no alarm will appear.

Derate gen-set

The purpose of the derate function is to be able to reduce the maximum output power of the gen-set, if specific conditions require this. An example of such a condition is the ambient

Adjust the derating speed. The adjustment is in percent per unit, i.e. if the 4…20mA input is used (analogue 100), then the derating will be in %/mA, and if the PT100/VDO input is used, then the derating will be in %/C.

The derate function is typically used when cooling problems are expected.

Refer to the type label for information about engine interface selection.

Be aware that the 4…20mA input can be configured with different minimum and maximum settings. In this case the settings ‘start derate point’ and ‘slope’ use these new settings.

Idle running

The purpose of the idle run function is to change the start and stop sequences to allow the genset to operate under low temperature conditions.

It is possible to use the idle run function with or without timers. Two timers are available. One timer is used in the start sequence, and one timer is used in the stop sequence.

The main purpose of the function is to prevent the gen-set from stopping. The timers are available to make the function flexible.

The function is typically used in installations where the gen-set is exposed to low temperatures which could generate starting problems or damage the gen-set.

Description

The function is enabled and configured in 6310 Idle running. It has to be noted that the governor itself must handle the idle speed based on a digital signal from the unit (see the principle diagram below).

When the function is enabled, two digital inputs are used for control purposes:

No. Input Description

1 Low speed input This input is used to change between idle speed and

nominal speed. This input does not prevent the gen-set from

stopping - it is only a selection between idle and nominal

speed.

2 Temperature control input When this input is activated, the gen-set will start. It will not

be able to stop as long as this input is activated.

The speed governor must be prepared for the idle run function, if this function is to be used.

The input must be configured through the PC software at commissioning.

One extra relay output must be available on the unit. Notice that this is option dependent.

Turbo chargers not originally prepared for operating in the low speed area can be damaged, if the gen-set is running in ‘idle run’ for too long.

AGC Designer’s Reference Handbook

DEIF A/S Page 87 of 168

Examples

Idle speed during starting and stopping In this example both the start and the stop timers are activated.

The start and stop sequences are changed in order to let the gen-set stay at the idle level before speeding up. It also decreases the speed to the idle level for a specified delay time before stopping.

The run status is deactivated, when idle run is active. This means that all protections set to ‘RUN’ will be inhibited.

The oil pressure alarm will be enabled at all times, no matter if it is set to ‘RUN’ or ‘ON’.

Master clock

The purpose of the master clock is to control the frequency of the gen-set in order to obtain the correct number of periods.

In a 50Hz system one period lasts 20 ms. If this changes, e.g. due to the dead band setting of the frequency controller, a difference will exist between the actual number of periods and the theoretical number of periods.

Equipment that works based on the zero crossings will be affected by the surplus or missing zero crossings. The most common example of such equipment is alarm clocks.

The unit’s internal clock is a timekeeper which is included in the battery backed memory circuit. The timekeeper function works based on an oscillating crystal instead of zero crossings of the AC measurements. Due to the accuracy of the timekeeper, it is recommended to synchronise the clock on a regular basis, e.g. once every month.

Compensation time

The time for the compensation can easily be calculated at a given adjustment of 6403 and 6404 (example):

• 6403 = 30 seconds

• 6404 = +/- 0.1Hz

This function can only be used, if island operation is selected.

If the power management option is selected (option G5), then the adjustment is made in the command unit.

Battery test

This function gives the possibility to test the condition of the battery. The battery test initiates with a digital input and is available when the gen-set is in semi-auto mode.

If a mains failure occurs during the battery test sequence, the test will automatically be interrupted, and the automatic mains failure start up sequence will be activated.

During the test the battery voltage will decrease, and an alarm will occur if it drops to the setpoint.

The drawing shows that test #1 is carried out without a large voltage drop of the battery voltage, whereas test #2 reaches the alarm setpoint.

As there is no reason to wear the battery down even more, the test stops when the battery test alarm occurs.

The test is typically used at periodical intervals, e.g. once every week. The engine must be at a standstill when the test is started. Otherwise, the test command will be ignored.

The stop relay will act depending on the coil type selection in

Input configuration

If this function is to be used, it is necessary to configure a digital input that initiates the function. This is done in the dialog box below.

Fail class

All activated alarms must be configured with a fail class. The fail classes define the category of the alarms and the subsequent alarm action.

Six different fail classes can be used. The tables below illustrate the action of each fail class when the engine is running or stopped.

Start relay

Run coil

Stop coil

Start test

If AUTO mode is selected, the mains failure sequence will be initiated, if a mains failure occurs during the battery test.

AGC Designer’s Reference Handbook

DEIF A/S Page 94 of 168

Engine running

The table illustrates the action of the fail classes. If, for instance, an alarm has been configured with the ‘shutdown’ fail class, the following actions occur.

• The alarm horn relay will activate

• The alarm will be displayed in the alarm info screen

• The generator breaker will open instantly

• The gen-set is stopped instantly

• The gen-set cannot be started from the unit (see next table)

Fail class configuration

The fail class can be selected for each alarm function either via the display or the PC software.

To change the fail class via the PC software, the alarm function to be configured must be selected. Select the desired fail class in the fail class roll-down panel.

In addition to the actions defined by the fail classes, it is possible to activate one or two relay outputs, if additional relays are available in the unit.

The fail class ‘trip and stop’ will only deload the gen-set before opening the breaker, if option G5 (power management) is included.

AGC Designer’s Reference Handbook

DEIF A/S Page 95 of 168

Service timers

The unit is able to monitor the maintenance intervals. The menu is available in the system setup.

6090 Service timer

The function is based on running hours. When the adjusted time expires, the unit will display an alarm. The ‘alarm acknowledge’ function resets this alarm.

When acknowledging the alarm, the timer will be reset and a new service timer alarm will only reoccur after the adjusted time has elapsed. The running hours is counting, when the running feedback is present.

Wire break detection

If it is necessary to supervise the sensors/wires connected to the analogue inputs (4-20mA, VDO and PT100), then it is possible to use the menus 4370-4430 depending on the HW options available in the unit. If the measured value on the input is outside the normal dynamic area of the input, it will be detected, as if the wire has made a short circuit or a break. An alarm with a configurable fail class will be activated.

Wire failure area Normal range Wire failure area

4-20mA Below 4mA 4-20mA Above 20mA

VDO 104 0…40% - 60…100% VDO 105 0…40% - 60…100% VDO 106 0…40% - 60…100%

PT100 – 106 0…40% - 60…100% PT100 – 109 0…40% - 60…100%

The fail class drop down panel is activated, and the user wants to select the ‘trip of GB’ fail class.

AGC Designer’s Reference Handbook

DEIF A/S Page 96 of 168

Principle

The illustration below shows that when the wire of the input breaks, the measured value will drop to zero. Then the alarm will occur.

PT100 settings

The alarm setpoint of the PT100 inputs can be calculated in percent like this:

Example:

Required setpoint is 200 °C. The adjustment must be:

VDO settings

The alarm setpoint of the VDO inputs can be calculated in percent like this:

VDO 104, oil pressure:

VDO 105, cooling temp.:

VDO 106, fuel level:

The deviation is the alarm value entered in percent, and the setting is the required alarm setting

in ohms.

Example:

Required setpoint of VDO104 is 180Ω. The adjustment must be:

Functional description

1. Fire pump This input deactivates all protections except the overspeed protection and the emergency stop

input. The number of start attempts is 7 by default, but it can be configured in

6180 Start

attempts

. Also a special cool down timer is used in the stop sequence after an activation of this

input.

2. Access lock Activating the access lock input deactivates the control display push-buttons. It will only be

possible to view measurements, alarms and the log.

3. Running feedback The input is used as a running indication of the engine. When the input is activated, the start

relay is deactivated.

4. Remote start This input initiates the start sequence of the gen-set when semi-auto or manual mode is

selected.

5. Remote stop This input initiates the stop sequence of the gen-set when semi-auto or manual mode is

selected. The gen-set will stop without cooling-down.

6. Semi-auto Changes the present running mode to semi-auto.

7. Test Changes the present running mode to test.

8. Auto Changes the present running mode to auto.

9. Manual Changes the present running mode to manual.

AGC Designer’s Reference Handbook

DEIF A/S Page 99 of 168

10. Block Changes the present running mode to block.

11. Remote GB ON The generator breaker ON sequence will be initiated and the breaker will synchronise, if the

mains breaker is closed, or close without synchronising if the mains breaker is opened.

12. Remote GB OFF The generator breaker OFF sequence will be initiated. If the mains breaker is opened, then the

generator breaker will open instantly. If the mains breaker is closed, the generator load will be deloaded to the breaker open limit followed by a breaker opening.

13. Remote MB ON The mains breaker ON sequence will be initiated and the breaker will synchronise, if the

generator breaker is closed, or close without synchronising if the generator breaker is opened.

14. Remote MB OFF The mains breaker OFF sequence will be initiated, and the breaker will open instantly.

15. Remote alarm acknowledge Acknowledges all present alarms, and the alarm LED on the display stops flashing.

16. Auto start/stop The gen-set will start when this input is activated. The gen-set will be stopped, if the input is

deactivated. The input can be used when the unit is in island operation, fixed power, load take over or mains power export and the AUTO running mode is selected.

17. Remove starter The start sequence is deactivated. This means the start relay deactivates, and the starter motor

will disengage.

18. Reset analogue GOV/AVR outputs The analogue +/-20mA controller outputs will be reset to 0mA.

19. Manual GOV up If manual mode is selected, then the governor output will be increased.

20. Manual GOV down If manual mode is selected, then the governor output will be decreased.

21. Manual AVR up If manual mode is selected, then the AVR output will be increased.

When block mode is selected, the running mode cannot be changed by activatin

the digital inputs.

All analogue controller outputs are reset. That is the governor output and the AVR output, if option D1 is selected.

If an offset has been adjusted in the control setup, then the reset position will be the specific adjustment.

AGC Designer’s Reference Handbook

DEIF A/S Page 100 of 168

22. Manual AVR down If manual mode is selected, then the AVR output will be decreased.

23. Alarm inhibit Specific alarms are inhibited to prevent the alarms from occurring. Refer to page 69.

24. Generator breaker closed feedback (GB position ON) The input function is used as an indication of the generator breaker position. The unit requires

this feedback when the breaker is closed or a position failure alarm occurs.

25. Generator breaker open feedback (GB position OFF) The input function is used as an indication of the generator breaker position. The unit requires

this feedback, when the breaker is opened or a position failure alarm occurs.

26. Mains breaker closed feedback (MB position ON) The input function is used as an indication of the mains breaker position. The unit requires this

feedback, when the breaker is closed or a position failure alarm occurs.

27. Mains breaker open feedback (MB position OFF) The input function is used as an indication of the mains breaker position. The unit requires this

feedback, when the breaker is opened or a position failure alarm occurs.

28. Emergency stop The input shuts down the engine immediately. At the same time it opens the generator breaker.

29. External engine failure This input is an alarm input that can be given one of all the selectable fail classes.

30. Low speed Disables the regulators and keeps the gen-set running at a low RPM. All alarms set to ‘RUN’ will

be inhibited as long as the function is active.

31. Temperature control This input is part of the idle mode function. When the input is high, then the gen-set starts. It

starts at high or low speed, depending on the activation of the low speed input. When the input is deactivated, then the gen-set goes to idle mode (low speed = ON), or it stops (low speed = OFF).

32. Battery test Activates the starter motor without starting the gen-set. If the battery is weak, the test will cause

the battery voltage to drop more than acceptable, and an alarm will occur.

The manual governor and AVR increase and decrease inputs can only be used in manual mode.

Essential protections might also be inhibited, if this input is used.

The governor must be prepared for this function.

The shut-down fail class must be selected.
