The unit is a control and protection panel used in gensets. It shows the measured values on its
displays. The unit is designed to provide user friendliness for both the installer and the user.
Programming is usually unnecessary, as the factory settings have been carefully selected to fit most
applications. However programmable parameters allow the complete control over the generating set.
Programmed parameters are stored in a Non Volatile Memory and thus all information is retained even
in the event of complete loss of power.
The measured parameters are:
Mains voltage phase L1 to neutral
Mains voltage phase L2 to neutral
Mains voltage phase L3 to neutral
Mains voltage phase L1-L2
Mains voltage phase L2-L3
Mains voltage phase L3-L1

The unit is designed for panel mounting. The user should not be able to access parts of the
unit other than the front panel.
Mount the unit on a flat, vertical surface. The unit fits into a standard panel meter opening of
92x92 millimeters. Before mounting, remove the mounting brackets and connectors from the unit, then
pass the unit through the mounting opening. The unit will be maintained in its position by the mounting
brackets spring.
The output of the current transformers shall be 5 Amperes. The input current rating of the current
transformers may be selected as needed (between 10/5 and 9000/5 amps). Current transformer outputs
shall be connected by separate cable pairs from each transformer, to related inputs. Never use common
terminals or grounding. The power rating of the transformer should be at least 5 VA. It is recommended to
use 1% precision transformers.
If analogue senders (e.g. temperature, oil pressure or fuel level) are connected to the unit, it is not
possible to use auxiliary displays, otherwise the unit may be damaged. If temperature or oil pressure or
fuel level displays are already present on the generator control panel, do not connect the senders to the
unit. The unit is factory programmed for VDO type senders. However different types of senders are
selectable via programming menu. Please check the programming section.
The programmable digital inputs are compatible with both „normally open‟ and „normally
closed‟ contacts, switching either to BAT- or BAT+.
The charge alternator connection terminal provides also the excitation current, thus it is not
necessaryto use an external charge lamp.
WARNING: ELECTRICITY CAN KILL
ALWAYS disconnect the power BEFORE connecting
the unit.The fuse rating should be 6 Amps.
1) ALWAYS remove the plug connectors when inserting wires
with a screwdriver.
2) An appropriate and readily accessible set of disconnection devices
(e.g. automatic fuses) MUST be provided as part of the installation.
3) The building mains supply MUST incorporate appropriate
short-circuit backup protection (e.g. a fuse or circuit breaker) of
High Breaking Capacity (HBC, at least 1500A).
WARNING: THE UNIT IS NOT FUSED.
Use external fuses for Mains phases: L1,L2,L3, Generator
phase: L1, Battery positive: BAT(+).
Install the fuses as nearly as possible to the unit in a
place easily accessible for the user.
The fuse rating should be 6 Amps.
1.3 Wiring the Unit

Alarms indicate an abnormal situation in the generating set are divided into 3 priority levels:
1- ALARMS: These are the most important fault conditions and cause:
-The ALARM led to be on steadily,
-The genset contactor to be released immediately,
-The engine to be stopped immediately,
-The Horn, Alarm,Alarm+Load_dump and Alarm+Load_dump+Warning digital
outputs to operate, (if selected via programming menu)
2- LOAD_DUMPS: These fault conditions cause:
-The ALARM led to flash,
-The genset contactor to be released immediately,
-The engine to be stopped after Cooldown period,
-The Horn, Alarm+Load_dump and Alarm+Load_dump+Warning digital outputs to
operate, (if selected via programming menu)
3- WARNINGS: These conditions cause:
-TheWARNING led to be on steadily,
-The Horn and Alarm+Load_dump+Warning digital outputs to operate, (if selected
via programming menu)
If the ALARM MUTE button is long pressed, the Horn output will be deactivated; however
the existing alarms will persist and disable the operation of the genset.
Alarms operate in a first occurring basis:
-If an alarm is present, following alarms, load_dumps and warnings will not be accepted,
-If a load_dump is present, following load_dumps and warnings will not be accepted,
-If a warning is present, following warnings will not be accepted.
Alarms may be of LATCHING type following programming. For latching alarms, even if the alarm
condition is removed, the alarms will stay on and disable the operation of the genset. The existing alarms
may be canceled by pressing one of the operating mode buttons (TEST / OFF / AUTO).
Most of the alarms have programmable trip levels. See the programming chapter for adjustable
alarm limits.
4. ALARMS AND WARNINGS

DKG-119 User Manual V-27 (20.04.2012)
- 11 -
LOW OIL PRESSURE: Set if a signal is detected at the Low Oil Pressure Switch input or the oil
pressure value measured from the sender is below the programmed limit. Warning and alarm limits are
separately programmable for the oil pressure sender input. This fault will be monitored with Holdoff
Timer delay after the engine is running. Also if the oil pressure switch is open at the beginning of a start
attempt, then the engine will not be started and “Oil Pressure Exists!”information is displayed. When
the oil pressure switch closes, normal operation will be resumed.
HIGH TEMPERATURE: Set if a signal is detected at the High Temperature Switch input or the coolant
temperature value measured from the sender is above the programmed limit. Warning and alarm limits
are separately programmable for the temperature sender input.
LOW TEMPERATURE (warning) : Set if the coolant temperature value measured from the sender is
blow the Engine Heating Temperature limit.
LOW FUEL: Set if the the fuel level measured from the sender is below the programmed limit. Warning
and alarm limits are separately programmable for the fuel level sender input.
EMERGENCY STOP: Set if a signal is detected at the emergency stop input.
SPARE-1 / SPARE-2: Set if a signal is detected from the related spare fault input.
LOW SPEED / HIGH SPEED:Set if the generator frequency is outside programmed limits. These faults
will be monitored with Holdoff Timer delay after the engine is running. Low and high limits for warning
and alarm are separately programmable. Another high frequency shutdown limit which is 12% above the
high limit is always monitored and stops the engine immediately.
START FAIL (alarm): Set if the engine is not running after programmed number of start attempts.
STOP FAIL (warning): Set if the engine has not stopped before the expiration of the Stop Timer.
OVERLOAD (load_dump): Set if the genset phase current goes over the Overcurrent Limit for
Overload Timer. If the current goes below the limit before expiration of the timer then no alarm will be set.
EXCESS POWER (load_dump): Set if the genset phase power (KW) supplied to the load goes over the
Excess Power limit for Overload Timer. If the power goes below the limit before expiration of the timer
then no alarm will be set.
GENSET LOW VOLTAGE:Set if any of the generator phase voltages goes outside programmed limits
for Overload Timer. This fault will be monitored with holdoff timer delay after the engine is running.
GENSET HIGH VOLTAGE: Set if any of the generator phase voltages goes outside programmed limits
for Overload Timer. This fault will be monitored with holdoff timer delay after the engine is running.
LOW BATTERY VOLTAGE (warning): Set if the battery voltage goes below the programmed limit.
During engine cranking this fault is not monitored.
HIGH BATTERY VOLTAGE: Set if the battery voltage goes above programmed limits. Both warning and
alarm levels for high battery voltage are programmable.
CHARGE: Set if a charge alternator failure (or broken belt) occurs. This fault condition may result to a
warning or alarm following programming.

The modes of operation are selected by pushing the front panel keys. Changing the operation
mode while the genset is running will result into a behavior suitable for the new operating mode. For
example, if the AUTO mode is selected when genset is running at RUN mode, if mains phase voltages
are present then the genset will stop.
STOP: In this mode, the engine will be stopped.
AUTO: It is used for automatic genset operation. If the REMOTE START signal arrives, the diesel will be
started for programmed times after the preheat timer. When the engine runs, the crank relay will be
immediately deactivated. The engine will run without load during engine heating period. After this, if
alternator phase voltages and frequency are within limits, then the unit will wait for the generator contactor
period and the generator contactor will be energized.
When the REMOTE START signal is removed the engine will continue to run for the mains waiting period.
At the end of this period the generator contactor function is deactivated.If a cooldown period is given, the
generator will continue to run during cooldown period. At the end of the period, the fuel solenoid will be
de-energized and the diesel will stop. The unit will be readyfor the next REMOTE START cycle.
RUN:It is used to test the generator without REMOTE START signal. The engine will run unless another
mode is selected. To stop the engine, select AUTO or STOP mode.
The unit offers the possibility of REMOTE START mode of operation. Any digital input may be
assigned as Remote Start Input using Input Function Select program parameters.
The REMOTE START signal maybe a NO or NC contact, switching to either battery positive or
battery negative. These selections are made using programming menu.
It is also necessary to set the ACTION program parameter of the related input to 3in order to
prevent any alarm from this input.
In this mode the mains phases are not monitored. If the REMOTE START signal is present
then the mains will be supposed to fail, inversely if the REMOTE START signal is absent, then mains
voltages will be supposed to be present.

Fuel Level Sender Selection:
The Fuel Level Sender Ohms is also programmable.
Especially on engines without a body heater, or with a failing one, it may be desired that the
genset should not take the load before reaching a suitable temperature. The unit offers 2 different
ways of engine heating.
1. Timer controlled heating:
This operation mode is selected when the Engine Heating Method parameter is set to 0. In this
mode, the engine will run during parameter Engine Heating Timer, and then the genset will take the
load.
2. Timer and temperature controlled heating:
This operation mode is selected when the Engine Heating Method parameter is set to 1. In this
mode, at first the engine will run during parameter Engine Heating Timer, then it will continue to run
until the measured coolant temperature reaches the limit defined in parameter Engine Heating
Temperature. When the requested temperature is reached, the load will be transferred to the genset.
This operation mode may be used as a backup to the engine body heater. If the engine body is warm
the heating will be skipped.

It may be required that the engine runs at the idle speed for a programmed duration for engine
heating and cooldown. The idle operation duration is adjusted with the parameter Idle Speed Timer.
The idle speed will be set by the governor control unit of the engine.
Any of the spare relay outputs may be assigned as IDLE output using Relay Definition
program parameters. Also relays on an extension module may be assigned to this function.
The Idle speed operation is performed both in engine start-up and cool-down sequences.
Speed and voltage protections are disabled during idle speed operation.
The unit is able to provide a relay output in order to drive the block heater resistor.
The temperature reference is the coolant temperature measured from the the analog sender
input.
The block heater relay function may be assigned to spare relays using Relay Definition
program parameters. Also relays on an extension module may be assigned to this function.
The engine body temperature limit is adjusted using the parameter Engine Heating
Temperature. The same parameter is used for engine heating operation.
The relay will become active if the body temperature falls to 4 degrees below the limit set by
Engine Heating Temperature. It turns off when the body temperature exceeds Engine Heating
Temperature.
The unit is able to provide a relay output in order to drive the fuel pump motor. The fuel pump
is used in order to transfer fuel from the large capacity main tank (if exists) to the genset daily tank
which is generally integrated in the chassis and has a limited capacity.
The fuel level reference is measured through the analog fuel level sender. When the
measured fuel level falls below Fuel Pump Low Limit parameter, the fuel pump relay output will
operate. When the fuel level reaches Fuel Pump High Limit parameter, the relay will turn off. Thus
the chassis fuel tank level will be always kept between Fuel Pump Low Limit and Fuel Pump High
Limit parameters.
The fuel pump relay function may be assigned to spare relays using Relay Definition program
parameters. Also relays on an extension module may be assigned to this function.

The unit offers an optional SIMULATE MAINS signal input. Any digital input may be assigned
as Simulate Mains using Input Function Select program parameters.
It is also necessary to set the ACTION program parameter of the related input to 3in order to
prevent any alarms generated from this input.
The SIMULATE MAINS signal maybe a NO or NC contact, switching to either battery positive or
battery negative. These selections are made using the programming menu.
If the Simulate Mains input is defined and the input signal is active, the mains phases are not
monitored and supposed to be inside limits. This will prevent the genset from starting even in case of a
mains failure. If the genset is running when the signal is applied, then usual Mains Waiting and
Cooldown cycles will be performed before engine stop. When the SIMULATE MAINS signal is present,
the front panels mimic diagram‟s mains LEDs will reflect the mains voltages as present.
When the signal is passive, the unit will revert to normal operation and monitor the mains
voltage status.
The REMOTE START operation overrides SIMULATE
MAINS and FORCE TO START operations.
6.7 Mains Simulation (Disable Start)

DKG-119 User Manual V-27 (20.04.2012)

The Delayed Mains Simulation feature is used in battery backed up telecom systems where
batteries are able to supply the load during a certain period. The genset is requested to run only when
battery voltage drops below the critical level. Once the engine runs, the rectifier system starts charging
the batteries and the battery voltage goes up immediately. Thus the engine should continue to run a
programmed period for effective charging. The critical battery voltage level will be detected by an
external unit which provides the digital Simulate Mains signal for the genset control unit.
The unit offers an optional SIMULATE MAINS signal input. Any digital input may be assigned
as Simulate Mains using Input Function Select program parameters.
It is also necessary to set the ACTION program parameter of the related input to 3in order to
prevent any alarms generated from this input.
The SIMULATE MAINS signal maybe a NO or NC contact, switching to either battery positive or
battery negative. These selections are made using the programming menu.
If the Delayed Simulate Mains program parameter is set to 1 and the input signal is active
when the genset is not feeding the load, the mains phases are not monitored and supposed to be
inside limits. This will prevent the genset from starting when the simulate mains signal is present
(batteries charged). The genset will start when mains voltages are out of limits and the simulate mains
signal not present.
If the genset is running when the signal is applied, then MAINS SIMULATION will be
prevented during Flashing Relay Timer program parameter. After this, usual Mains Waiting and
Cooldown cycles will be performed before engine stop. When the SIMULATE MAINS signal is present,
the front panels mimic diagram‟s mains LEDs will reflect the mains voltages as present.
When the signal is passive, the unit will revert to normal operation and monitor the mains
voltage status.
The REMOTE START operation overrides DELAYED
SIMULATE MAINS operation. When both parameters
“Remote Start Operation” and “Delayed Simulate
Mains” are set then REMOTE START operation mode is
performed.

Dual genset intermittent operation consists of regular switching of the load between 2 gensets.
The use of 2 gensets instead of one is due either to safety purposes in case of a genset failure or to a
continuous operation requesting service stops.
The running period for each genset is adjustable using Flashing Relay Timer program
parameter. If the time is adjusted as 0 hours, it will be actually set to 2 minutes for faster testing
purposes.
A flashing relay output function is provided, based on the parameter Flashing Relay Timer.
Each time the period programmed using Flashing Relay Timer elapses, the relay output will change
position.
The flashing relay function may be assigned to spare relays using Relay Definition program
parameters. Also relays on an extension module may be assigned to this function.
The dual genset intermittent operation uses also the Mains Simulation feature. Please review
chapter 6.7 for a detailed explanation of this feature.
Priority In Dual Genset Mutual Standby Operation:
It may be required that the dual genset system starts the same genset at every mains failure.
This is achieved using the PRIORITY input.
Any digital input may be assigned as Priority using Input Function Select program
parameters.
It is also necessary to set the ACTION program parameter of the related input to 3in order to
prevent any alarms generated from this input.
The Priority signal may be a NO or NC contact, switching to either battery positive or battery
negative. These selections are made using the programming menu.
If a Priority input is defined, then the system will work in priority mode. If the priority signal is
applied, the unit will become master after each mains failure. If the priority signal is not applied, then
the unit will become the slave one and the other genset will start.
Please contact DATAKOM for a complete application
manual.

The periodic maintenance is basically carried out after a given engine hours (for example 200
hours), but even if this amount of engine hours is not fulfilled, it is performed after a given time limit (for
example 12 months).
The unit has both programmable engine hours and maintenance time limit. The engine hours is
programmable with 50-hour steps, the time limit is programmable with 1 month steps. If any of the
programmed values is zero, this means that the parameter will not be used. For example a maintenance
period of 0 months indicates that the unit will request maintenance only based on engine hours, there will
be no time limit. If the engine hours is also selected as 0 hours this will mean that the SERVICE
REQUEST function will be inoperative.
When the engine hours OR the time limit is over, the SERVICE REQUEST warning will occur and
the display will switch to the ALARM LIST.
The service request relay function may be assigned to spare relays using Relay Definition
program parameters. Also relays on an extension module may be assigned to this function.
The remaining engine hours and the remaining time limit are kept stored in a non-volatile memory
and are not affected from power supply failures.
The time and engine hours to service are displayed in the STATISTICAL COUNTERS menu.
The unit features a non-erasable incremental engine hour meter. The hour meter information is
kept in a non-volatile memory and is not affected from power supply failures.
Some additional features are installed within consecutive software releases. In order to be
sure of the validity of the status of the unit, the software version needs to be known.
The software version number represents the operating software version of the unit.

The GSM SMS sending is activated by setting the SMS Enable program parameter to 1.
When a fault condition occurs, the unit will compose an SMS message and will send it to up to 6
phone numbers.
The unit is also able to send SMS messages in below conditions, without creating a visible alarm
or warning:
Mains Fail, Mains Restored (enabled via SMS on Mains Change program parameter)
Fuel Theft, Fuelling (enabled by setting the Fuel Consumption / Hour parameter to other than 0)
When SMS sending is in progress, an (SMS) icon will appear at the upper right corner of the
screen.
The maximum number of alarms transmitted in a SMS message is 4. This limitation is due to the
maximum length of an SMS message which is 160 characters.
A sample GSM SMS message is given below:
DKGxxx <SITE-ID>
STOP :LOW OIL PRESSURE SW.
END OF ALARM LIST
The first line of the message carries information about the unit type and the site identitystring.
This line is intended for the identification of the genset sending the SMS message.
Each following line will give one fault information. The message will always be terminated by the
“END OF ALARM LIST” string.
When the message is sent, the existing alarms will be masked, causing the audible alarm relayto
release and preventing consecutive GSM SMS messages. Anynew upcoming alarm will result in a new
GSM SMS message. The new message will indicate all existing alarms, even masked ones.
The necessary GSM modem cable will be supplied by DATAKOM. This is the same cable as
PSTN (land) modems.
A logic level to RS-232 converter is necessary
in order to connect the unit to modem.
If SMS Enable or MODBUS Address parameters are
different from zero, the local PC connection will not work.
