2-10. Arc Failure Light Connections
S-0292
. Arc Failure light on robot inter-
face front panel turns on and off
by a signal from robot control
unit. Obtain proper length of 18
gauge/2-conductor cord for
this connection.
For robot control units when 24 vdc
is used:
1 Route cord through strain
relief on right side panel of
robot interface, and make
proper connections to 1TL
and 1TM.
2 Route and connect remaining
end of cord to weld alarm
terminal and ground
connection at the robot control
unit.
3 Connect +24 vdc to common
relay contact terminal.
For robot control units when 115 or
24 vac, or 24 vdc is used:
1 Route cord through strain
relief on right side panel of
robot interface, and make
proper connections to 1TL
and 1TM.
2 Obtain a 115 or 24 vac, or 24
vdc isolation relay CR1, and
install into robot control.
3 Route and connect remaining
end of cord to one side of the
normally-open robot control
relay contact and ground.
4 Connect +24 vdc to remaining
side of normally-open robot
control relay contact.
5 Connect a lead from one side
of robot control coil to weld
alarm terminal.
6 Connect proper voltage
source (115 vac, 24 vac, or 24
vdc) between common
terminal and remaining side of
robot control relay coil.
