4. ALARMS AND WARNINGS
Alarms indicate an abnormal situation in the generating set are divided into 2 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 and Alarm+Warning relays output to operate, (if selected via programming
menu)
2- WARNINGS: These conditions cause:
- The related alarm led to flash,
- The Horn and Alarm+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 is present, following alarms 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 settable alarm limits.
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: Set if the engine is not running after programmed number of start attempts. (P_035)
STOP FAIL: 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_024). 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.
FUEL LEVEL: 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.

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 (22) 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_119 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 diagram’s 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_131 to P_142.
1: VDO 0-7 bars (10-180 ohms)
2: VDO 0-10 bars (280-20 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_143 to P_154.

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 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.
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 upper display will show “HtS” (hours to service). The mid display will show the first
3 digits of the engine hours to service and the bottom display the last 3 digits.
For the time, the upper display will show “ttS” (time to service). The mid display will show the first 3 digits of
days to service and the bottom display the last 3 digits.
6.5 Engine Hour Meter
The unit features a non-erasable incremental engine hour meter. The hour meter information is kept in a nonvolatile
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 upper display will show “EnH” (engine hours). The mid display will show the first 3
digits of the engine hours and the bottom display the last 3 digits.
6.6 Modem Connection
The unit offers the remote monitoring and programming features over the telephone network via a
modem connection. The program used for remote monitoring and programming is the same as the program used
for RS-232 connection.
If the modem is connected, the program parameter P_043 should be set to 1, otherwise faulty operation
may occur.

6.7 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 may be downloaded from www.datakom.com.tr
internet site.
The 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 :
DIGITUS USB 2.0 TO RS-232 ADAPTER (PRODUCT CODE: DA70146 REV 1.1)
DIGITUS USB 1.1 TO RS-232 ADAPTER (PRODUCT CODE: DA70145 REV 1.1)
FLEXY USB 1.1 TO SERIAL ADAPTER (PRODUCT CODE BF-810)
CASECOM USB TO SERIAL CONVERTER (MODEL: RS-01)
6.8 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_155: Exercise start day and hour
P_156: Exercise duration
P_157: Exercise off_load/on_load
P_158: 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.

7. 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_051 to P_064. 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_051: 07.0 (Monday morning 07:00 turn on)
P_052: 18.0 (Monday evening 18:00 turn off)
P_053: 07.0 (Tuesday morning 07:00 turn on)
P_054: 18.0 (Tuesday evening 18:00 turn off)
P_055: 07.0 (Wednesday morning 07:00 turn on)
P_056: 18.0 (Wednesday evening 18:00 turn off)
P_057: 07.0 (Tuesday morning 07:00 turn on)
P_058: 18.0 (Tuesday evening 18:00 turn off)
P_059: 07.0 (Friday morning 07:00 turn on)
P_060: 18.0 (Friday evening 18:00 turn off)
P_061: 07.0 (Saturday morning 07:00 turn on)
P_062: 13.3 (Saturday noon 13:30 turn off)
P_063: 24.0 (Sunday no turn on time, last operation mode continues)
P_064: 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.

8. EVENT LOGGING
The unit keeps records of the last 12 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.
The events are only displayed on the PC screen using the remote monitoring and programming software.
They can not be displayed on the unit.
The event sources are:
-Genset on load,
-Genset off load,
-Alarms,
-Warnings.
9. 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.

The parameters from P_051 to P_064 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

12. 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.
