m. VALVE MODE (Advanced Models ONLY)
Select the output method (1 VALVE or 2 VALVE) of the solenoid valve signal.
When
1 VALVE is selected
When the 1ST STAGE signal is input, the valve signal (SOL1 - 4) with the selected schedule number is
output and the sequence waits for the 2ND STAGE signal input. Next, when the 2ND STAGE signal is
input, the welding sequence with the selected schedule number starts. After the welding sequence starts,
the valve signal is output until the sequence ends even if the 1ST STAGE signal is turned OFF.
T: DELAY START SET (1 to 20ms)

When 2 VALVE is selected
2 valve signals (VALVE 1, 2) are output in a sequence.
When VALVE 1 is used, the weld force position can be adjusted by the 1ST STAGE signal
output timing of VALVE 2 to the start of SQZ.
After the welding sequence starts, the valve signal is output until the sequence ends even if the
1ST STAGE signal is turned OFF. When VALVE MODE is set to 2 VALVE, the following
functions become disabled.
