HOLD
The sequence proceeds from CO2/WE3 to HOLD by pressing the ENTER key or input the STEP
MODE signal. The force set in HOLD is output to the electro pneumatic proportional valve
(ANALOG OUT), and HOLD and CONTINUE blink.
The measured value input in the force input (ANALOG IN) is displayed at the monitor of HOLD.
Turning off the step operation mode
The step operation mode ends by pressing the
ENTER
key or input the
STEP MODE
signal.
Open the 1ST signal. The force output to the electro pneumatic proportional valve (ANALOG
OUT) becomes the setting on the setting on the PRESSURE REGULATOR screen, and
HOLD
and
CONTINUE
stops blinking.
d. SQD
Set the force of the electro pneumatic proportional valve (ANALOG OUT) output during SQD.
e. SQZ
Set the force of the electro pneumatic proportional valve (ANALOG OUT) output during SQZ.
f. WE1
Set the force of the electro pneumatic proportional valve (ANALOG OUT) output during WE1.
g. CO1/WE2
Set the force of the electro pneumatic proportional valve (ANALOG OUT) output during
CO1/WE2.
h. CO2/WE3
Set the force of the electro pneumatic proportional valve (ANALOG OUT) output during
CO2/WE3.
i. HOLD
Set the force of the electro pneumatic proportional valve (ANALOG OUT) output during HOLD.
j. VALVE #
Two or four valves (welding heads) can be connected to the Power Supply. Use this setting to
select which of the two valves to use.
Operation differs according to the VALVE MODE setting on the MODE SELECT screen.
When VALVE MODE is 1 VALVE
Set the valve # in the range of 1 to 4.
EX SOL1 to EX SOL4 on the I/O terminal block.
VALVE #1: EX SOL1
VALVE #3: EX SOL3
VALVE #2: EX SOL2 VALVE #4: EX SOL4
