1. INSTALLATION 
1.1 Introduction to the Control Panel 
 
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 R to neutral 
Mains voltage phase S to neutral 
Mains voltage phase T to neutral 
Mains voltage phase R-S 
Mains voltage phase S-T 
Mains voltage phase T-R 
Gen voltage phase U to neutral 
Gen voltage phase V to neutral 
Gen voltage phase W to neutral 
Gen voltage phase U-V 
Gen voltage phase V-W 
Gen voltage phase W-U 
Gen current phase U 
Gen current phase V 
Gen current phase W 
Gen frequency  
Engine speed (rpm) 
Gen total KW 
Gen total cos 
Battery voltage, 
Coolant temperature 
Oil pressure 
Fuel level 
Gen frequency  
 
1.2 Mounting the Unit 
 
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 183x134 
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. 
 
 
Engine body must be grounded for correct operation of 
the unit, otherwise incorrect voltage and frequency 
measurements may occur. 
 
  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 necessary 
to use an external charge lamp.

1.3 Wiring the Unit 
 
 
WARNING: THE UNIT IS NOT FUSED. 
Use external fuses for 
Mains phases: R-S-T 
Generator phase: U-V-W  
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. 
 
 
WARNING: ELECTRICITY CAN KILL 
 ALWAYS disconnect the power BEFORE connecting the unit. 
 
 
1)  ALWAYS remove the plug connectors when inserting wires with a screwdriver.  
2)  ALWAYS refer to the National Wiring Regulations when conducting installation. 
3)  An appropriate and readily accessible set of disconnection devices (e.g. 
automatic fuses) MUST be provided as part of the installation. 
4)  The disconnection device must NOT be fitted in a flexible cord. 
5)  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). 
6)  Use cables of adequate current carrying capacity (at least 0.75mm
2
) and 
temperature range.

4. ALARMS AND WARNINGS 
  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 related 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 relays output 
to operate, (if selected via programming menu) 
 
2-  LOAD_DUMPS: These fault conditions cause: 
-  The related alarm led to be on steadily, 
-  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 relays output to 
operate, (if selected via programming menu) 
 
3-  WARNINGS:  These conditions cause: 
-  The related alarm led to flash, 
-  The Horn and Alarm+Load_dump+Warning relay outputs to operate, (if selected via 
programming menu) 
 
If the ALARM MUTE button is pressed, the Horn relay 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 or load_dump is present, following alarms, 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 (LOAD TEST / TEST / OFF / AUTO). 
  Most of the alarms have programmable trip levels. See the programming chapter for adjustable alarm 
limits.

      - 10 -   
 
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 (P_015) and alarm (P_016) limits 
are separately programmable for the oil pressure sender input. This fault will be monitored with holdoff timer 
(P_023)  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 the oil  pressure led  will flash. 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  (P_017)  and  alarm 
(P_018) limits are separately programmable for the temperature sender input. 
SPEED:  Set if the generator frequency is outside programmed limits (overspeed/Underspeed). This fault will 
be  monitored  with  holdoff  timer  (P_023)  delay  after  the  engine  is  running.  Different  low  and  high  limits  for 
warning and alarm are separately programmable. (P_008/P_009/P_010/P_011) 
START FAIL (alarm): Set if the engine is not running after programmed number of start attempts. (P_035) 
STOP FAIL (warning): Set if the engine has not stopped before the expiration of the Stop Timer (P_034).  
OVERLOAD: Set if at least one of the genset phase currents goes over the Overcurrent Limit (P_002) or if 
the  genset  power  (KW)  supplied  to  the  load  goes  over  the  Excess  Power  (P_003)  limit  for  Overcurrent  / 
Excess  Power Timer  (P_24).  If  the  currents  and  power  goes  below  the  limits  before  expiration  of  the  timer 
then no alarm will be set. 
VOLTAGE: Set if any of the generator phase voltages goes outside programmed limits (P_006/P_007). This 
fault will be monitored with holdoff timer (P_023) delay after the engine is running. 
LOW FUEL: Set when the fuel level falls below 10%. 
COOLANT LEVEL: Set when a signal is detected from the coolant level switch input. 
BATTERY: Set if the battery voltage goes outside programmed limits. During engine cranking this fault is not 
monitored. Warning level for low battery voltage (P_012) and both warning (P_013) and alarm (P_014) 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. (P_038) 
RECTIFIER FAIL: Set if a signal is detected at the rectifier fail input. This input is only monitored when mains 
voltages are present. 
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. 
ECU FAIL (warning):   Set when an engine fault code is received from the ECU of the electronic engine. This 
fault will not cause an engine stop. If necessary, the engine will be stopped by the ECU. 
ECU FAIL (alarm): Set if no information has been received during 3 seconds from the ECU of the electronic 
engine. This fault condition is only controlled if fuel is on.

5. MODES OF OPERATION 
 
  The modes of operation are selected by pushing the front panel keys. Changing the operation mode 
while the genset is running  will result to a behavior suitable for the new  operating  mode. For example, if the 
LOAD TEST mode is selected when genset is running at TEST mode, then the genset will take the load. 
 
OFF: In this mode, the mains contactor will be energized if mains phase voltages are within the programmed 
limits. The engine will be stopped. 
 
AUTO:  It  is  used  for  genset  and  mains  automatic  transfer.  If  at  least  one  of  the  mains  phase  voltages  is 
outside limits (P_004/P_005), the mains contactor will be deactivated. 
The  diesel  will  be  started  for  programmed  times  (P_035)  after  the  wait  period  (P_0026).  When  the  engine 
runs, the crank relay  will  be immediately deactivated. The engine  will run  without  load during engine heating 
period (P_029). After this, if alternator phase voltages and frequency are within limits, then the unit will wait for 
the generator contactor period (P_032) and the generator contactor will be energized. 
When all the mains phase voltages are within the limits, the engine will continue to run for the mains waiting 
period (P_030). At the end of this period the generator contactor is deactivated and the mains contactor will be 
energized. If a cooling period is given (P_031), the generator will continue to run during cooling period. At the 
end of the period, the fuel solenoid will be de-energized and the diesel will stop. The unit will be ready for the 
next mains failure. 
If  the  operation  of  the  genset  is  disabled  by  the  weekly  schedule,  then  the  AUTO  led  will  flash,  and  the 
operation of the genset will be as in the OFF mode. 
 
TEST: It is used to test the generator when the mains are on, or keep the generator running in the emergency 
backup mode (P_041). The operation of the generator is similar to the AUTO mode, but the mains contactor 
will not be deactivated if the mains are not off. If the mains are off, mains contactor will be deactivated and the 
generator contactor will be activated. When the mains are on again, a changeover to the mains will be made, 
but the engine will be kept running unless another mode is selected. To stop the engine, select AUTO or OFF 
mode. 
 
LOAD TEST: It is used to test the genset under load. Once this mode is selected, the engine will run and the 
load  will  be  transferred  to  the  genset.  The  genset  will  feed  the  load  indefinitely  unless  another  mode  is 
selected.  
 
 
6. OTHER FEATURES 
 
6.1 Remote Start Operation 
 
  The unit offers the possibility of REMOTE START mode of operation. If the program parameter 
P_042 is set to 1 then the unit will enter to the Remote Start operation. The Remote Start signal should be 
connected to the SPARE_2 (35) input.  
 
  The REMOTE START signal may be 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 program parameter P_139 to 3 in order to prevent the alarms generated 
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. The front panels mimic diagrams mains LEDs will reflect the status of the 
REMOTE START input.

6.2 Sender type Selection 
 
  The unit has the ability to adapt to any type of oil pressure and temperature senders. The 
commonly used standard sender characteristics are recorded in memory and selectable from a list. 
However non standard senders may also be used by entering their characteristics to the table. 
 
Oil Pressure Sender Type Selection: 
The oil pressure sender is selected using parameter P_019. The selectable sender types are: 
0: The sender characteristics are defined in table using parameters P_151 to P_162. 
1: VDO 0-7 bars (10-180 ohms) 
2: VDO 0-10 bars (10-180 ohms) 
3: DATCON 0-7 bars (240-33 ohms) 
4: DATCON 0-10 bars (240-33 ohms)  
5: DATCON 0-7 bars (0-90 ohms) 
6: DATCON 0-10 bars (0-90 ohms) 
7: DATCON 0-7 bars (75-10 ohms) 
 
Temperature Sender Selection: 
The temperature sender is selected using parameter P_020. The selectable sender types are: 
0: The sender characteristics are defined in table using parameters P_163 to P_174. 
1: VDO 
2: DATCON DAH type 
3: DATCON DAL type 
 
Fuel Level Sender Selection: 
The fuel level sender input is factory set for VDO 0-100% (10-180 ohms) and not adjustable. 
 
6.3 Engine Heating Operation 
 
  Especially on engine 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 parameter P_037 is set to 0. In this mode, the engine will run 
during parameter P_029, and then the genset will take the load. 
 
2. Timer and temperature controlled heating: 
This operation mode is selected when the parameter P_037 is set to 1. In this mode, at first the engine will 
run during parameter P_029, then it will continue to run until the measured coolant temperature reaches 
the limit defined in parameter P_022. 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. 
 
6.4 Engine Idle Operation 
 
  It may be required that the engine runs at the idle speed for a programmed duration for heating. 
The idle operation duration is adjusted with the parameter P_055. 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 program parameters 
P_085/P_086. Also relays on an extension module may be assigned to this function. 
   
DKG-507-J User Manual                                                                           V-22 (30.09.2009) 
 
 
      - 13 -   
 
6.5 Engine Block Heater 
 
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 program parameters 
P_085/P_086. Also relays on an extension module may be assigned to this function. 
The engine body temperature limit is adjusted using the parameter P_022. 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 
P_022. It turns off when the body temperature exceeds P_022. 
 
6.6 Fuel Pump Control 
 
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 to 25 % the fuel pump relay output will operate. When the fuel level reaches 75 % the relay 
will turn off. Thus the chassis fuel tank level will be always kept between  and .  
The fuel pump relay function may be assigned to spare relays using program parameters 
P_085/P_086. Also relays on an extension module may be assigned to this function. 
 
6.7 Mains Simulation 
 
  The unit offers an optional SIMULATE MAINS signal input. If the program parameter P_050 is set 
to 1 then the SPARE_2 (35) input will be used for mains simulation.  
  It is also necessary to set the program parameter P_139 to 3 in order to prevent any alarm generated 
from this input. 
  The SIMULATE MAINS 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 the program parameter P_050 is set to 1 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 diagrams 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 operation. 
When both parameters P_042 and P_050 are set then REMOTE START 
operation mode is performed. 
 
DKG-507-J User Manual                                                                           V-22 (30.09.2009)

6.8 Delayed Mains Simulation, Battery Charging 
 
  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. If the program parameter P_063 is set 
to 1 then the SPARE_2 (35) input will be used for delayed mains simulation.  
  It is also necessary to set the program parameter P_139 to 3 in order to prevent any alarm generated 
from this input. 
  The SIMULATE MAINS 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 the program parameter P_063 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 voltage 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 Max Engine Run Timer (P_047). 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 
diagrams 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 P_042 and P_063 are set then 
REMOTE START operation mode is performed. 
 
 
6.9 Dual Genset Intermittent Operation 
 
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 porposes in case of a genset failure or to a 
continuous operation requesting service stops. 
The running period for each genset is adjustable between 0 and 144 hours using parameter 
P_047. If the time is adjusted as 0 hours, it will be actually set to 2 minutes for faster testing purpose. 
A flashing relay output function is provided, based on the parameter P_047. Each time the period 
programmed using P_047 elapses, the relay output will change position. 
The flashing relay function may be assigned to spare relays using program parameters 
P_085/P_086. 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. 
Please contact DATAKOM for a complete application manual. 
DKG-507-J User Manual                                                                           V-22 (30.09.2009)

6.10 Service Request Display 
 
This led is designed to help the periodic maintenance of the genset to be made consistently. 
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 SERVICE REQUEST led has no effect on the genset 
operation. 
 
The  unit  has  both  programmable  engine  hours  and  maintenance  time  limit.  The  engine  hours  is 
programmable  with  50-hour  steps  (P_044),  the  time  limit  is  programmable  between  with  1  month  steps 
(P_045). 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 display will be inoperative. 
 
When the engine hours OR the time limit is over, the SERVICE REQUEST led (red) will start to flash 
and the service request relay function will be active. 
The service request relay function may be assigned to spare relays using program parameters 
P_085/P_086. Also relays on an extension module may be assigned to this function. 
 
To turn off the led, and reset the service period, press together the  ALARM MUTE and LAMP 
TEST keys for 5 seconds. The upper display will show SER. 
 
The remaining engine hours and the remaining time limit are kept stored in a non-volatile memory and 
are not modified by power supply failures.  
 
  The remaining time and engine hours to service may be checked via the statistics menu selected by 
pressing the MENU key for 1 second. 
 
  For the engine hours, the first display will show HtS (hours to service). The second display will show 
the first 3 digits of the engine hours to service and the third display the last 3 digits. 
 
  For the time, the first display will show ttS (time to service). The second display will show the first 3 
digits of days to service and the third display the last 3 digits. 
 
 
6.11 Engine Hour Meter 
 
The unit features a non-erasable incremental engine hour meter. The hour meter information is kept in 
a non-volatile memory and is not modified by power supply failures.  
 
  The engine hours may be displayed via the statistics menu selected by pressing the MENU key for 1 
second. 
 
  For the engine hours, the first display will show EnH (engine hours). The second display will show 
the first 3 digits of the engine hours and the third display the last 3 digits.

6.12 Date & Time Display 
 
The date & time display is provided for verification. The date & time display is selected by pressing 
the MENU button twic eafter the statistics group is selected by holding the MENU button pressed. 
 
6.13 Software Version Display 
 
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 display is selected by pressing 3 times the MENU button after the statistics 
group is selected by holding the MENU button pressed. 
The software version consists of 2 numbers. The first number represent the operation software 
version and the second number represent the J1939 software version. 
   
6.14 Modem Connection 
 
  The unit is capable of making modem calls in case of alarm, as well as answering modem calls 
made from a remote location. GSM modems as well as classic cable network (PSTN) modems are 
acceptable. 
  If the modem is connected to the unit, the program parameter P_043 should be set to 1, otherwise 
faulty operation may occur. If the parameters P_043 or P_056 are different from zero, the local PC 
connection will not work. 
  A maximum of 2 telephone numbers can be defined for outgoing modem calls. In case of alarm, 
the unit will attempt to reach control centers associated with each number. In case of modem connection 
failure, the call will be repeated up to 30 times with 2 minute intervals. 
 
 
If SMS message sending is enabled, then only the first telephone number will be 
used for modem calls. 
 
  Telephone numbers can only be entered from the PC. They cannot be entered from the front 
panel. 
  Advised modems are DATAKOM types which are powered up from the same DC battery voltage 
than the unit. Most of other desktop modems with standard AT commands are also usable, but it is the 
users responsibility to provide an uninterrupted AC supply source to the modem. The necessary modem 
cable will be supplied by DATAKOM. 
  Modem calls are always terminated by the central RAINBOW software. However the unit does not 
allow connection durations exceeding 2 minutes, and hangs up the modem when this period expires. 
  The PC program used for remote monitoring and programming is the same RAINBOW software 
used for RS-232 connection.  
  Please note that the modem operation is also compatible with the MODBUS communication. Thus 
the unit can iniate and receive calls to/from a MODBUS master station. Please review chapter_8 for more 
details on MODBUS communication. 
DKG-507-J User Manual                                                                           V-22 (30.09.2009)

6.15 SMS Message Sending 
 
  The GSM SMS message sending is activated by setting the program parameter P_056=1. When the 
GSM SMS mode is activated, the PC connection will not work. If a local PC connection is necessary, the 
parameters P_043 and P_056 should be set to 0. 
  When a fault condition occurs, the unit will compose an SMS message and will send it to the second 
phone number. The telephone number can only be entered from the PC. It cannot be entered from the front 
panel. 
  The maximum number of alarms transmitted in a SMS message is 6. 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 PR. 
STOP :HIGH TEMP. 
STOP :EMERG.STOP 
STOP :COOL.LEVEL 
WARNING :ECU WARN. 
END OF ALARM LIST 
 
 
  The first line of the message carries information about the unit type and the site identity string. This 
string can only be entered  from the PC. It cannot be entered from the front panel. This line is intended for 
the correct identification of the genset. 
  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 relay to 
release and preventing more GSM SMS messages. Any new 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 cable 
modems. 
 
6.16 Remote Monitoring and Programming 
 
Thanks to its standard serial RS-232 port, the unit offers the remote monitoring and programming 
feature. 
The  remote  monitoring  and  programming  PC  software  is  called  RAINBOW  and  may  be 
downloaded from www.datakom.com.tr internet site with password login. 
  The modem and SMS modes are not compatible with the local PC connection. Program parameters 
P_043 and P_056 should be set to 0 before connection. 
The  RAINBOW  software  allows  the  visualization  and  recording  of  all  measured  parameters.  The 
recorded  parameters  may  then  be  analyzed  graphically  and  printed.  The  software  also  allows  the 
programming  of  the  unit  and  the  storage  of  the  program  parameters  to  PC  or  the  downloading  of  stored 
parameters from PC to the unit. 
 
  For PCs without a serial port, below USB to serial adapters are tested and approved :

6.17 Exerciser 
 
  The unit offers automatic exerciser operation. The exercise operation may be done on a daily, 
weekly or monthly basis.  
  The start day and time of the exercise is programmable as well as its duration. The exercise may 
be done with or without load following programming. 
  The program parameters related to the exerciser are: 
  P_175: Exercise start day and hour 
  P_176: Exercise duration 
  P_177: Exercise off_load/on_load 
  P_178: Daily / Weekly / Monthly Exercise 
  Please refer to the programming section for a more detailed description of the above parameters. 
  When the start day and hour of exercise has come, the unit will automatically switch to either TEST 
or LOAD TEST mode. The engine will run and if the on_load exercise is selected then the load will be 
transferred to the genset.  
  If a mains failure occurs during the off-load exercise, the load will not be transferred to the genset 
unless the Emergency Backup Operation is allowed by setting the parameter P_041 to 1. Thus it is 
highly recommended that the Emergency Backup mode enabled with off-load exerciser. 
  At the end of the exercise duration, the unit will switch back to the initial mode of operation. 
  If any of the mode selection keys are pressed during exercise, then the exercise will be ended. 
  Using the daily exercise mode, the unit may feed the load from the genset during predefined hours 
of the day. This operation may be used in high tariff periods of the day. 
 
6.18. Resuming to factory set parameters 
 
  In order to resume to the factory set parameter values: 
  -hold pressed the OFF and ALARM MUTE buttons for 5 seconds, res will be displayed 
  -press and hold pressed the ALARM MUTE button for 5 seconds, factory set values will be    
  reprogrammed to the parameter memory. Displays may flash during the operation. 
 
  It is not possible to revert back to the user parameters. 
 
 
6.19. Gas Engine Fuel Solenoid Control 
 
The unit provides a special function for the fuel solenoid control of a gas engine.  
 
  The fuel solenoid of a gas engine is different from a diesel engine. It should be opened after the 
cranking has been started and should be closed between crank cycles. The delay between the crank start 
and solenoid opening is adjusted using the parameter P_60.    
   
The gas engine fuelsolenoid relay function may be assigned to spare relays using program 
parameters P_085/P_086. Also relays on an extension module may be assigned to this function.

6.20. Changing the Default Engine Speed in Volvo Engines 
 
  Volvo engines equipped with EMS-II engine control unit have the engine speed selectable through 
the J1939  CANBUS. The unit offers the possibility to the user to switch between the primary and 
secondary speed using the programming menu. 
 
  The parameter used is P_062. When this parameter is set to 1, the unit will freeze for a few 
seconds and switch the engine to 1800 rpm, which is generally the secondary speed. When the parameter 
is set 0, the speed is set to the primary speed, which is generally 1500 rpm. 
 
 
The unit must be in OFF mode when speed is switched, otherwise the switching will 
not be performed. 
 
  Please note also that a fine adjustment of the engine speed in the  8 % range may be done using 
the program parameter P_058. 
 
7. J1939 ENGINE MONITORING AND CONTROL PORT 
 
  The unit offers a special J1939 port in order to communicate with electronic engines controlled by 
an ECU (electronic control unit).  
 
  The J1939 port consists of 2 terminals which are J1939+ and J1939-. The connection between the 
unit and the engine should be made with either a twisted cable pair or a coaxial cable. If a coaxial cable is 
used, the external conductor should be grounded at one end only. 
 
  The 120 ohms termination resistor is included inside the unit. Please do not connect external 
resistor. 
 
  The J1939 port is activated by setting the parameter P_051=1. The engine type should be selected 
using parameter P_052. The list of available engines is given at the programming section. Please contact 
DATAKOM for the most current list of engines. 
 
  If the J1939 port is enabled (P_51=1) then the oil pressure, the coolant temperature and the 
engine speed information are picked up from the ECU unit. Other available measurements of the engine 
are not displayed by the unit, but they are available for PC and MODBUS communications. Please check 
the chapter 8 for more details. 
 
  When the fuel output is active, if no information is received from the ECU during last 3 seconds, 
then the unit will give a ECU FAIL alarm and stop the engine. This feature prevents uncontrolled engine 
operation. 
 
  The fault conditions of an electronic engine are considered by the unit as warnings and do not 
cause engine stop. The engine is supposed protected by the ECU which will stop it when necessary. 
 
  The electronic engine fault codes are displayed on the unit as SPN-FMI pairs. A maximum of 8 
fault codes can be displayed. 
 
  The fault code group is displayed by holding pressed the MENU button after the statistics screen 
has been reached. If there is no failure, no number will be displayed. The complete list of fault codes is 
given in the engine manufacturers user manual.

8. MODBUS COMMUNICATION 
 
  The unit offers the possibility of MODBUS communication via its RS232 serial port. 
  The connection to the MODBUS master may be done in 3 ways: 
    1) RS232 connection using directly the RS232 port provided. 
    2) RS422/485 connection using external RS422/485 converter. 
    3) Modem connection using external modem. 
  The MODBUS mode is activated by assigning a controller address to the unit using parameter 
P_057. The possible address range is 1 to 144. Setting the address 0 will disable the MODBUS mode and 
allow communication under RAINBOW protocol. 
  The MODBUS properties of the unit are: 
  -Data transfer mode: RTU 
  -Serial data: 9600 bps, 8 bit data, no parity, 1 bit stop 
  -Supported functions:  
    -Function 3 (Read multiple registers)

9. WEEKLY OPERATION SCHEDULE 
 
  In most applications, the genset is requested to operate only in working hours. Thanks to the 
weekly program feature unwanted operation of the genset may be prohibited. 
 
  The unit has one programmable turn-on/turn-off time pairs for each day of week. These 
programmable parameters allow the genset to operate automatically only in allowed time limits. 
 
  The weekly operation schedule is only active in AUTO mode. In other modes it will not affect the 
genset operation.  
 
In AUTO mode, if the operation of the genset is disabled by the weekly schedule, then the AUTO 
led will flash (instead of a steady on state). 
 
  Each turn-on/turn-off time is defined in 10 minute steps. These parameters are defined in the 
parameters P_071 to P_084. On the display, the parameters are shown with 3 digits, the first 2 digit are the 
hour and the last digit is the first digit of the minutes. For example 19.3 will mean 19:30.  
   
  Unused programs should be set to 24.0. 
 
  An example setup may be as follows: 
 
  P_071: 07.0 (Monday morning 07:00 turn on) 
  P_072: 18.0 (Monday evening 18:00 turn off) 
  P_073: 07.0 (Tuesday morning 07:00 turn on) 
  P_074: 18.0 (Tuesday evening 18:00 turn off) 
  P_075: 07.0 (Wednesday morning 07:00 turn on) 
  P_076: 18.0 (Wednesday evening 18:00 turn off) 
  P_077: 07.0 (Tuesday morning 07:00 turn on) 
  P_078: 18.0 (Tuesday evening 18:00 turn off) 
  P_079: 07.0 (Friday morning 07:00 turn on) 
  P_080: 18.0 (Friday evening 18:00 turn off) 
  P_081: 07.0 (Saturday morning 07:00 turn on) 
  P_082: 13.3 (Saturday noon 13:30 turn off) 
  P_083: 24.0 (Sunday no turn on time, last operation mode continues) 
  P_084: 24.0 (Sunday no turn off time, last operation mode continues) 
 
  If the same time is used for turn on and turn off, then it will be considered as a turn-on time. 
 
  The unit has a battery backed-up precision real time clock circuit. The real time clock circuit will 
continue its operation even in power failures. The real time clock is precisely trimmed using the program 
parameter P_046. For more details check the programming section. 
DKG-507-J User Manual                                                                           V-22 (30.09.2009)

10. EVENT LOGGING 
 
  The unit keeps records of the last 32 events in order to supply information for the service personal. 
 
  The events are recorded with a date and time stamp. The date and time information comes from 
the internal battery backed-up real time clock circuit of the unit. The real time clock circuit will continue its 
operation even in power failures. The real time clock is precisely trimmed using the program parameter 
P_046. For more details check the programming section. 
 
  The events are stored in a circular memory. This means that a new coming event will erase the 
oldest recorded event.  
  In order to view the event records please hold pressed the MENU button when the J1939 alarms 
are visualized. The latest event record will be displayed. Each depression of the MENU button will cause 
the previous record to come to the display. After the oldest record, the last record will be displayed again. 
 
  The event sources are: 
-Genset on load, 
-Genset off load, 
-Alarms, 
-Warnings. 
 
  A sample event record is as follows:

11. STATISTICAL COUNTERS 
 
The unit provides a set of non resettable incremental counters for statistical purposes.  
 
  The counters consist on: 
 
  -total engine cranks, 
  -total genset runs, 
  -total genset on load. 
 
  These counters are kept in a non-volatile memory and are not affected from power failures. 
 
  The statistical counters are only displayed on the PC screen using the remote monitoring and 
programming software. They can not be displayed on the unit. 
 
 
12. MAINTENANCE 
 
 
DO NOT OPEN THE UNIT  
There are NO serviceable parts inside the unit. 
 
Wipe the unit, if necessary with a soft damp cloth. Do not use chemical agents 
 
13. PROGRAMMING 
 
The program mode is used to program the timers, operational limits and the configuration of the unit.  
To enter the program mode, press the MENU button for 5 seconds. The program mode is only allowed 
if the PROGRAM LOCK input is left open. If this input is tied to GROUND, the program value modification will be 
disabled to prevent unauthorized intervention. It is advised to keep the PROGRAM LOCK input tied to GROUND. 
  The program parameters are organized in two groups as SERVICE and FACTORY parameters. Entering  
the program mode normally, will allow access only to the SERVICE group of parameters. In FACTORY mode, all 
parameters may be accessed. 
  In order to enter the FACTORY mode, please press and hold pressed the OFF button, then press and 
hold the MENU button for 5 seconds. When the PGM mode is opened, all parameters are available. 
The  program  mode  will  not  affect  the  operation  of  the  unit.  Thus  programs  may  be  modified  anytime, 
even while the genset is running. 
When the program mode is entered, the upper display will show PGM. The central display will show the 
program parameter number and the lower/right display the program parameter value. The first program number is 
000 
Each depression of the MENU key will cause the display to switch to the next program parameter. If the 
MENU  key  is  hold  pressed  the  program  numbers  will  increase  by  steps  of  10.  After  the  last  parameter,  the 
display switches back to the first parameter.  The displayed parameter value may be increased or decreased using 
 and  keys. If these keys are hold pressed, the program value will be increased/decreased by steps of 10. 
  Program parameters are kept in a non-volatile memory and are not affected from power failures. 
To exit the program mode press one of the mode selection keys. If no button is pressed during 1 minute 
the program mode will be cancelled automatically.

  The parameters from P_071 to P_0847 program the weekly operation schedule feature. For each day of 
week, one turn_on time and one turn_off time are provided. Times are defined with 10 minute steps and are 
shown in the 3 digit display as the hours and the first digit of the minutes. If no operation is needed for a certain 
day of week, then the related time will be defined as 24.0; thus the last definition will continue to be valid. For 
example if the turn_on and turn_off times for Sunday are given as 24.0 then the unit will not operate automatically 
from Saturday turn_off time to Monday turn_on time. If the AUTO mode is disabled by the weekly operation 
schedule, then the AUTO led will flash, otherwise it is steadily on.

175  Exercise start day and 
hour 
-  168  This parameter defines the start day and hour 
of the exerciser.  
Values higher or equal to 168 mean that the 
exerciser is off.  
The exercise may be selected to start at the 
beginning of the any hour of the week. The 
parameter value is the hour count of the start 
time. 
Examples:  
  0 = exercise starts at Monday 00:00   
  1 = exercise starts at Monday 01:00 
  8 = exercise starts at Monday 08:00 
 24 = exercise starts at Tuesday 00:00 
167 = exercise starts at Sunday 23:00 
168 = exerciser off  
 
If a daily exercise is selected with parameter 
P_158=0, then the day information is dont 
care and the exercise will be performed every 
day regardless of the day selection. 
If the monthly exercise is selected with 
parameter P_158=2 then the exercise will be 
performed during the first 7 days of each month 
at the programmed day and hour. 
 
176  Exercise duration  min.  10  This parameter defines the exercise duration 
and programmed in 10 minute steps up to 24 
hours. 
177  Exercise off_load/on_load  -  0  If this parameter is set to 0 the genset will not 
feed the load during exercise. If it is set to 1, 
then the load will be transferred to the genset 
during the exercise.

14. TROUBLESHOOTING 
 
 
The genset operates while AC mains are OK or continues to operate after AC mains are OK: 
 
-Check engine body grounding. 
-AC mains voltages may be outside programmed limits, measure the phase voltages. 
-Check the AC voltage readings by pressing the MENU button.  
-Upper and lower limits of the mains voltages may be too tight. Check the parameters P_004 and P_005.       
Standard values are 170/270 volts. 
-The hysteresis voltage may be given to excessive. Check the parameter P_021, the standard value is 8 
volts. 
 
 
AC voltages or frequency displayed on the unit are not correct:  
 
-Check engine body grounding, it is necessary. 
-The error margin of the unit is +/- 3 volts.  
-If  there  are  faulty  measurements  only  when  the  engine  is  running,  there  may  be  a  faulty  charging 
alternator or voltage regulator on the engine. Disconnect the charging alternator connection of the engine 
and check if the error is removed. 
-If  there  are  faulty  measurements  only  when  mains  are  present,  then  the  battery  charger  may  be  failed. 
Turn off the rectifier fuse and check. 
 
 
Phase-to-Phase AC voltages are not correct although Phase to Neutral  voltages are correct:  
 
-Incorrect phase order. Please connect phase voltages in the correct order. 
 
 
KW and cos readings are faulty although the Amp readings are correct: 
 
-Current  transformers  are  not  connected  to  the  correct  inputs  or  some  of  the  CTs  are  connected  with 
reverse  polarity.  Determine  the  correct  connections  of  each  individual  CT  in  order  to  obtain  correct  KW 
and cos for the related phase, and then connect all CTs.  
 
 
Short circuit the outputs of unused Current Transformers. 
 
 
When  the  AC  mains  fails  the  unit  energizes  the  fuel  solenoid,  but  does  not  start  and  OIL 
PRESSURE led flashes: 
 
The unit is not supplied with battery (-) voltage at the oil pressure input. 
-Oil pressure switch not connected. 
-Oil pressure switch connection wire cut. 
-Oil pressure switch faulty. 
-Oil  pressure  switch  closes  too  lately.  If  oil  pressure  switch  closes,  the  unit  will  start.  Optionally  oil 
pressure switch may be replaced. 
 
 
The  engine  does  not  run  after  the  first  start  attempt,  then  the  unit  does  not  start  again  and  OIL 
PRESSURE led flashes:  
 
-The oil pressure switch closes very lately. As the unit senses an oil pressure, it does not start. When oil 
pressure switch closes the unit will start. Optionally the oil pressure switch may be replaced.

When the  AC mains fails, the engine starts to run but the unit gives START FAIL alarm and then 
the engine stops:  
 
-The generator phase voltages are not connected to the unit. Measure the AC voltage between terminals 
U-V-W  and  Generator  Neutral  at  the  rear  of  the  unit  while  the  engine  is  running.  A  fuse  protecting  the 
generator phases may be failed. A misconnection may be occurred. If everything is OK, turn all the fuses 
off, and then turn all the fuses on, starting from the DC supply fuse. Then test the unit again. 
 
 
The unit is late to remove engine cranking: 
 
-The  generator  voltage  rises  lately.  Also  the  generator  remnant  voltage  is  below  20  volts.  The  unit 
removes starting  with the generator frequency, and needs at least 20 volts to measure the frequency. If 
this  situation  is  to  be  avoided,  the  only  solution  is  to  add  an  auxiliary  relay.  The  coil  of  the  relay  will  be 
between BATTERY (-) and charging alternator D+ terminal. The normally closed contact of the relay will 
be connected serially to the unit's START output. So the starting will also be removed when the D+ pulls 
to battery positive. 
 
 
The unit is inoperative: 
 
Measure  the  DC-supply  voltage  between  terminals  11  and  12  at  the  rear  of  the  unit.  If  OK,  turn  all  the 
fuses off, then turn all the fuses on, starting from the DC supply fuse. Then test the unit again. 
 
 
Programming mode can not be entered:  
 
The program lock input disables programming mode entry. Disconnect the program lock input from 
battery negative before modification. Do not forget to make this connection again to prevent unauthorized 
program modifications. 
 
 
Some program parameters are skipped:  
 
These parameters are reserved for factory setting and cannot be modified. 
 
 
AUTO led flashes and the genset does not run when mains fail:  
 
The unit is in Weekly Schedule OFF time. Please check date and time setting of the unit. Please check 
also Weekly Schedule programs (parameters P_071 to P_084).
