REMOTE 14-PIN CONNECTIONS
REMOTE 14-Pin Connections
The REMOTE 14-Pin receptacle is used to connect any of the following
equipment to the welding power source circuitry:
- Remote Contactor Control
- Remote Amperage Control
- Wire Feeder (one which provides contactor to welding power source)
- Combination of the above
To make connections, align keyway, insert plug, and rotate threaded collar
fully clockwise. The socket information is included in the event the supplied
cord is not suitable and it is necessary to wire a plug or cord to interface
with the REMOTE 14-Pin receptacle
Socket
A
Up to 10A of 24VAC, 60Hz, with respect to Socket G (circuit
common): protected by circuit breaker MCB3
B
Input to energize the solid-state contactor, 24VAC (contact closure is
provided between Sockets A and B to energize the solid-state
contactor)
C
Amperage remote control (MAXIMUM) input command signal; +10V
for maximum
D
Amperage remote control (MINIMUM); PC board common; use as
return for remote control input/outputs
E
Remote amperage reference signal (WIPER); 0 to +10V (peak current
set by main rheostat) in CC or CV mode
F
Output current monitor (1V per 100A)
G
24 and 115VAC circuit common; also connected to welding power
source chassis
H
Output voltage monitor (1V per 20V)
I
Up to 1.5A of 115VAC, 60Hz, with respect to Socket G (circuit
common); protected by circuit breaker MCB2
J
115VAC input control to energize solid state contactor (constant
closure is provided between Sockets I and J)
K
Chassis common
L
Not Used
M
Current detect (When output current detected, socket M and
N will be shorted by a relay. OK-TO-MOVE)
N
Current detect sensor - (When output current detected, socket M and N
will be shorted by a relay. OK-TO-MOVE.)
