6.1.2 Fuel pre heating system SWK-2000/40/MH or MHS
In the heated filter of the SWK-2000/40 series, a heating power of 1400 W is fed into the fuel. The
heating system is in a 230 V and a 440 VAC version available.
Attention
The heater voltage must always be switched to the filter via an external contactor
with sufficient breaking capacity. The heater voltage may only be switched on when
the contact between pins C and D (Hummel connector: 3 and 4) of the control
terminal is closed. In case of interruption between pins C and D (Hummel connector: 3
and 4) the heater voltage must be switched off immediately! Other switching states
can cause damage to the heating filter.
Control electronics
The control electronics are identical for all versions of the filters described here.
Operating voltage: 24 VDC
Maximum operating voltage: 36 VDC
Minimum operating voltage: 16 VDC
Power input: < 10 W
