Figure 5-1 Grid Heater - Mbe4000 - Detroit Diesel DDEC VI Application And Installation

FEATURES
Waiting for Engine Start
A cranking detection before the end of time waiting for start leads to the engine starting state. If
the engine does not start then Cold Start is canceled.
Engine Start
If engine start is successful or if the engine starting time ends, the post-heating state starts.
Post-heating State
When the engine start is successful, the grid heater will be switched on until the post-heating time
expires or the coolant temperature exceeds the switch off temperature.
Cooling Off
This time is used to determine the preheating time at the beginning of the next cold start.
Off
End of the Cold Start procedure, all outputs are switched off.
5.2.2 INSTALLATION
The Engine Harness has the grid heater connector. The OEM is responsible for wiring power
and ground to the grid heater. See Figure 5-1 for the MBE4000, Figure 5-2 for the MBE900 and
