10. 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 (terminal_23) 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 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 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.

Current Transformer
Primary
A 500
This is the rated value of current transformers.
All transformers must have the same rating.
The secondary of the transformer will be 5
Amps. For values over 990A use 10% of the
value. These values will be displayed as K-
Amperes. (for ex. 1.85KA) Values under 100A
may be used by multiplying with 10 in order to
enable the current display with 0.1A precision.
(for ex: 35.7A)

Current Transformer
Decimal Point
0
This parameter determines the display range of
current and active power:
0: 000-999
1: 0.00-9.99
2: 00.0-99.9
2 Overcurrent Limit A 500
If the current goes above this limit, during the
period defined in P_024 an OVERLOAD alarm
will be generated. Enter this information with the
same format as parameter P_000.
3 Excess Power Limit KW 350
If the active power goes above this limit, during
the period defined in P_024 an OVERLOAD
alarm will be generated. Enter this information
with the same format as parameter P_000.
4 Mains Voltage Low Limit V 170
If one of the mains phases goes under this
limit, it means that the mains are off and it
starts the transfer to the genset in AUTO and
TEST modes.
5 Mains Voltage High Limit V 270
If one of the mains phases goes over this limit,
it means that the mains are off and it starts the
transfer to the genset in AUTO and TEST
modes.
6 Gen. Voltage Low Limit V 180
If one of the generator phase voltages goes
under this limit when feeding the load, this will
generate a VOLTAGE alarm and the engine will
stop.
7 Gen. Voltage High Limit V 270
If one of the generator phase voltages goes over
this limit when feeding the load, this will generate
a VOLTAGE alarm and the engine will stop.
