9) Power Module Assembly
The power module assembly is mounted under the output table which is located at the rear of the
machine over the generator. The assembly consists of the rectifier, a current transformer and an
output contactor. The rectifier converts the generator AC output to DC
10) Cold Weather Starting System (BH1)
The intake air heater, located on the intake manifold, is used for starting the engine at very cold
temperatures and reduces the white smoke associated with a cold start. The intake air heater (or grid
heater) is energized or de-energized from a power relay controlled by the ECM. The amount of time
the air intake heater stays on, in the preheat phase, is a function of the intake manifold temperature at
start up. (The pre-heat time increases with colder intake manifold temperatures). The maximum
duration of the pre-heat phase is around 30 seconds.
CAUTION
Never use an ether start system in conjunction with the air intake heater.
