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 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 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.
