High Idle Wiring
The programming includes a high idle function. To activate the high idle provide
a +12 VDC High Idle Active Input. (Refer to Figure 8. High Idle Wiring.)
Note: It is important that the connection to the Interlock Input from the High
Idle circuit be isolated from the apparatus interlock wiring with the two
diodes. Refer to the wiring diagram. The pump must NOT be engaged
when using the high idle function.
The high idle is set at about 1000 RPM at the factory. (This value will vary
depending on the specic engine.) To adjust this setting refer to High Idle in the
Operation Section.
Cables
There are two connectors on the control module for all input/output signals, one
8-pin connector and one 12-pin connector.
When replacing an older Detroit Diesel governor, connectors with wiring are
provided to utilize some of the existing harness. New wiring is required for the intake
pressure sensor and engine control. Refer to the Wiring Section.
