3.2 Preheater (option)
3.2.1 Description heating operation
When switched on the signal lamp in the mini-clock control element is lit. The waterpump starts and
after a fixed programme with prerinsing and preheating, combustion air fan, glow plug and fuel
dosing pump set combustion going. Once a stable flame has formed, the glow plug is switched off
by a timer.
Depending on the heat requirement, the heater wil switch between three levels, LARGE, SMALL and
OFF (control interval). The temperature thresholds have been fixed programmed in the electronic
control device. If the heat requirement at level SMALL is so low that the cooling water temperature
reaches 85°C (185°F), the device goes into control interval. This is followed by the fan continuing
to run for about 130 sec. The signal lamp will stay lit during the control interval and also the
waterpump continues to run.
If the heater does not ignite within 90 seconds after fuel pumping has started, the start procedure
must be repeated. If the heater once again fails to ignite after 90 seconds a fault shut down is
effected.
It is possible to override a fault shut-down by briefly switching the heater off and then on again.
When an emergency stop has to be performed:
•
Switch off the preheater at the control element
•
Remove the fuse or disconnect the heater from the battery
Safety procedure before starting after a longer period of standstill
Check whether the fuse is in its place and / or the wiring is connected to the battery.
Check if all parts are firmly fixed.
