6290 Idle mode
Idle mode can be selected in two ways:
1. Configurable binary input
2. Timer setting
If a binary input for idle mode is used, activating this will hold the engine in idle mode as long as
the input is activated. This works for both manual and auto mode. Any time the idle mode is
activated, the generator breaker will be opened.
If a binary input is not used, a timer function can be set to hold the engine in idle upon start until
the timer runs out. This function can be selected to be:
• Off (no idling of engine upon start)
• Modes:
- Manual and auto: Select Man./Aut.
- Manual only: Select Man.
- Auto only: Select Aut.
In all cases, a relay must be selected to Idle in the output list. When idle mode is selected, a
delay where the engine is running at low RPM is given. The delay is controlled by the GC-1F,
and a relay output will activate the idle control on the engine.
Engine heater
The external heater function can be used to turn on an external heat source, when the engine
cooling water temperature gets below the limit in parameter 6320. When the engine cooling
water temperature reaches the temperature set point in parameter 6330, the heater is turned off
again.
A relay must be selected in the output list to turn this external heat source on/off. The relay will
close to turn the heater on or open to turn it off.
This function will only work, if the engine cooling water temperature sensor is selected to be a
VDO sensor.
