6. Interface
6-4
Pin No. Name Description
15
COM COM pin. This pin is internally connected to the GND chassis.
16
1ST
1ST STAGE input pin. (This function is not available with this
Power Supply.)
17
2ND
2ND STAGE input pin.
Closing this pin will start the sequence.
18
COM COM pin. This pin is internally connected to the GND chassis.
19
WELD ON
Weld ON pin.
Close this pin to turn ON the WELD ON/OFF signal, and open it
to turn it OFF. Leaving this pin open will shut off welding current
even when the sequence operation is performed. Use this pin,
for example, to start the sequence experimentally.
20
THERMOSTAT
Thermostat input pin for an external transformer.
Connect to the transformer thermostat or diode thermostat.
Opening the pin will result in a thermostat error.
21
FLOWSWITCH
Flow switch input pin. Opening this pin will result in a flow rate
error.
22
COM COM pin. This pin is internally connected to the GND chassis.
23
ERROR
RESET
Error/caution reset input pin.
Eliminate the cause of error or caution and close this pin to
reset the error or caution indication.
24
STEP RESET
Step reset input pin. Closing this pin while the STEPPER is ON
will reset the STEP number to 1.
25
WE3 STOP
WE3 stop input pin. Closing this pin during the WELD3
sequence will switch the sequence to HOLD. The current
shutoff error occurs when the WE3 STOP signal is input before
the start signal is input, even if WELD1 or WELD2 has been set.
26
NG
Error signal output pin.
This signal is output upon completion of the welding sequence
in the event of an operational error. If an error occurs, operation
will halt until the reset signal is input.
The contact is rated at 24
V DC at 20 mA (semiconductor
switch).
27
CAUTION
Caution signal output pin.
This pin is closed upon completion of the welding sequence if
the measured value is outside the range set on the MONITOR
SET screen. You can continue with your welding task even if a
caution signal is activated. To cancel this caution output, input
the reset or start signal.
The contact is rated at 24
V DC at 20 mA (semiconductor
switch).
28
END
End signal output pin.
This pin is closed for a preset length of time after completion of
the sequence. It is closed for the length of time during which this
pin is closed can be set in a range from 10
ms to 200 ms and in
units of 10
ms. This signal is also output when the sequence
operation is performed in the WELD OFF state.
The contact is rated at 24
V DC at 20 mA (semiconductor
switch).
