26, the weld control (when wired to the machine as shown in Figure 9-17) will hold
the part just previously welded, between the electrodes, if the measured current is not between
the programmed HIGH/LOW limit window. The valve assignment must be as follows:
Valve 1 TS1-SV1 Connects to Valve 1 for Electrodes
Valve 2 TS1-SV3 Connects to CR1 which drives Magnetic Isolation Contactor
Valve 3 TS1-SV5 Connects to Alarm Output CR2
On weld controls with a PROGRAM LOCKOUT key switch, the key must be rotated and
error cleared before the part can be removed from the welder.
9.7.1 VALVE 1 (Welding Head Solenoid Output for Electrodes)
Program desired schedule using Valve 1 for SQUEEZE, WELD, and HOLD times (set VALVE
MODE=
0303

03).
This valve will stay on after the sequence is complete if current is out of programmed HIGH/
LO limit window. If current is within limit window, the valve will turn off at end of HOLD.
