Terminals Description
A P22 CHASSIS GND. This terminal provides the chassis ground
connection. The DGC-500 must be hard-wired to earth ground with
no smaller than 12 AWG copper wire.
B
P20 (+, P21 (–)
BATT. DGC-500 operating power is applied to these terminals. The
DGC-500 accepts a nominal input of 12 Vdc or 24 Vdc.
C
P35 (+), P37 (–)
P2, P3, P4
Contact Sensing Terminals
ESTOP. These terminals function as the Emergency Stop input.
Power is removed from all DGC-500 output relays when this input is
open.
PROG INPUT1, PROG INPUT2, PROG INPUT3. These three inputs
can be independently programmed to function as an auto transfer
switch input, single-phase override input, low coolant level input, fuel
leak detection input, battery charger failure input, or an auxiliary
input. The inputs accept normally-open contacts connected between
terminals P2 (PROG INPUT1), P3 (PROG INPUT2), or P4 (PROG
INPUT3) and terminal P21 (BATT –).
D
P39 (+), P40 (–)
P13
P16
P18
P19
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.
E
P23
P26
P29
P30
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.
F
P10 (1/5A), P11 (COM)
P12 (1/5A), P14 (COM)
P15 (1/5A), P17 (COM)
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.
