Sockets G and K are electrically isolated from each other.
1 Available with optional Automation Expansion memory card.
2 Available with optional Modbus Expansion memory card. Modbus serial communication provides access to all front panel parameters and
machine functionality. See Owner's Manual 265415 for a list of Modbus registers. Modbus expansion also includes functionality of Automa-
tion, Hot Wire, and Hot Start Adjust expansions.
�
If a remote hand control like the RHC-14 is connected to the Remote 14 receptacle, some current value above min. must be set on the
remote control before the Panel or Remote contactor is turned on. Failure to do so will cause current to be controlled by the panel con-
trol, and the remote hand control will not function.

Socket Socket Information
A Contactor control +15 volts DC, referenced to G.
Contact closure to A completes 15 volts DC con-
B
tactor control circuit and enables output.
Output to remote control; +10 volts DC output to
C
remote control.
D Remote control circuit common.
0 to +10 volts DC input command signal from re-
mote control.
1 Reconfigurable as input for Output Enable
(Weld Stop) - used to remotely stop the weld
E
outside the normal welding cycle. Connection to
the D socket must be maintained at all times. If
the connection is broken, output stops, and Auto
Stop is displayed.
Current feedback; +1 volt DC per 100 amps
F
output.
Voltage feedback; +1 volt DC per 10 volts
H
output.
Valid arc indication closed to socket G with valid
arc. Electrical specifications: open collector tran-
I 1
sistor (see Section 5-11 for connection
example).
Arc length control lockout closed to socket G
during Initial and Final Amperage and Slope,
and during the background time of a <=10 Hz
J 1
pulse waveform. Electrical specifications: open
collector transistor (see Section 5-11 for connec-
tion example).
Touch Sense Detection closed to Socket G, with
2
Modbus's Touch Sense enabled and machine
not triggered for weld output.
G Return for all output signals: F, H, I, J and A.
K Chassis
L 2 Modbus Common (RS485 Common)
M 2 Modbus D1 (RS485 B+)
N 2 Modbus D0 (RS485 A-)
Coil CR1 resistance plus R should be chos-
en to limit current to 75 mA.
User supplied power up to 27 volts DC peak.
