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.

Pgm Definition Unit Std Val Description

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

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.
