Transducer Terminals
MPU. These terminals accept the output from a magnetic pickup.
Voltage applied to this input is scaled and conditioned for use as a
speed signal.
OIL PRESS. The output from an oil pressure transducer is applied to
this input. A current signal lower than 5 mA can be applied between
terminal P13 and P19 (SENDER COMM).
FUEL LEVEL. The output from a fuel level transducer is applied to
this input. The DGC-500 supplies a transducer current signal of less
than 30 mA to terminals P13 and P19 (SENDER COMM).
COOLANT TEMP. The output from a coolant temperature transducer
is applied to this input. The DGC-500 supplies a transducer current
signal of less than 5 mA to terminals P16/P18 and P19 (SENDER
COMM).
SENDER COMM. This terminal functions as the common return line
for all of the transducer inputs.

Voltage Sensing Terminals
VOLT PH A. This terminal senses the A-phase generator voltage.
VOLT PH B. This terminal senses the B-phase generator voltage.
VOLT PH C. This terminal senses the C-phase generator voltage.
VOLT NEUTRAL. This terminal connects to the generator Neutral in
phase-to-neutral sensing applications.

Current Sensing Terminals
PHASE A CT. These terminals sense the A-phase generator current.
PHASE B CT. These terminals sense the B-phase generator current.
PHASE C CT. These terminals sense the C-phase generator current.
G P24 (+), P25(–) HORN. This output supplies power to an external horn. The voltage
supplied is 24 Vdc or the battery voltage, whichever is less. A
maximum current of 15 mAdc is available.
H J2 SAE J1939 Connector. This connector is enabled on controllers with
a style number of FXJ and provides high-speed communication
between the DGC-500 and the ECU on an electronically controlled
engine.
I J1 RS-232 COMMUNICATION PORT. This DB9 connector uses serial
communication to enhance DGC-500 setup. A standard serial cable
connects the DGC-500 to a PC.

Output Contact Terminals
CRANK. This output is closed when the DGC-500 is initiating engine
cranking.
FUEL. This output closes when engine cranking is initiated and
remains closed until a stop command is received by the DGC-500.
PRE-START. This output closes to energize the glow plugs prior to
engine cranking. Depending on system setup, the Pre-Start output
may open upon engine startup or stay closed during engine
operation.
PROGRAM OUTPUT1. This output closes when a user-
programmable condition is detected by the DGC-500.
PROGRAM OUTPUT2. This output closes when a user-
programmable condition is detected by the DGC-500.
