Description
CON1
Speed signal input for crank disconnect, engine run, and over-speed sensing. Be
sure to use twisted pair wiring for this connection. An 8-foot wiring harness is
supplied as standard. 300 VAC max. input voltage.
1
Lamp test. Conn12/24 VDC to lamp test activates all the front panel
LED’s. NOTE: Annunciation outputs DO NOT activate under led test.
2
Oil pressure switch. For proper operation, oil input must be connected to ground
or +12/24 VDC via an oil switch. This switch
must
be the N.O. type, close on
failure (low pressure)
3
Temperature switch. For proper operation, temperature input must be connected
to ground or +12/24 VDC via a temperature switch. This switch
must
be the
N.O. type, close on failure (high temperature).
4
The Auxiliary input. For proper operation, Aux. Input must be connected to
ground or +12/24 VDC via a sensor switch. This switch
must
be the N.O. type,
close on failure.
5
Crank output provides 10A maximum. Crank output closes to +12/24 VDC
during cranking, and opens when the engine has started, or during crank rest.
6
Battery ground connection for the controller module. A good ground connection,
directly from the battery
, is required for proper operation.
7
Auto terminal. When +12/24 VDC is applied; the controller is in the standby
mode waiting for a Start/Stop signal (+12/24 VDC applied to Start/Stop).
8
RSC1, provided for the connection of one lead from the remote start contacts of
the transfer switch (BROWN connection of 5-wire interconnect harness)
9
RSC2, provided for the connection of other lead from the remote start contacts
of the transfer switch (GREEN connection of 5-wire interconnect harness)
10
(Start/Stop) terminal. When +12/24 VDC is applied, the controller proceeds to
starting the engine.
11
Fuel output provides 10A maximum. Fuel output closes to +12/24 VDC when
start signal is actuated, and opens when either an Engine failure is detected or
when stop signal is applied.
12
The Preheat/TDES output provides 300mA maximum. This output closes to
+12/24 VDC when activated.
13
Low Oil pressure output provides 300mA maximum. Oil output closes to +12/24
VDC when the engine shuts down due to a Low Oil pressure condition. Flashing
Low Oil output indicates an Auxiliary Input failure.
14
High water temperature output provides 300mA maximum. Temperature output
closes to +12/24 VDC when the engine shuts down due to a high temp condition.
15
Over-crank output provides 300mA maximum. Over-crank output closes
to+12/24 VDC when the engine shuts down due to an Over-crank failure.
16
Over-speed output provides 300mA maximum. Over-speed output closes to
+12/24 VDC on an Over-speed failure and is open otherwise. Flashing output
indicates Loss of Speed Signal.
