Pin No. Description
20
Interrupt Input Terminal.
The function is changed in dependence on the selection of WELD
STOP (INPUT) at 6.(8)CONTROL Screen.
* In the case of OFF selected at INPUT,
When this Pin is closed while the sequence works at WE1 (W1),
COOL (CO) and WE2(W2), the sequence skips to HOLD.
* In the case of DISPLC**, CURR and VOLT selected at INPUT,
This terminal does not work.
** (Only for Displacement Sensor equipped)
21
Program Protection Input Terminal.
If the Pin is closed, the condition of settings cannot be changed.
In order to make the settings effect, once turn off the power supply.
22
COM Terminal. Internally connected to GND Chassis.
23
GOOD Signal Output Terminal.
If it is determined that the measured value is inside the range set in
MONITOR Screen after a weld sequence has ended, the Pin keeps
closed for the certain period. The period of closing can be selected
among HOLD, 10ms and 100ms. The rated capacity of a contact is
24VDC 20mA (Semi-conductor switch used).
24
NG Signal Output Terminal.
The signal is output when the measured value goes out of the range
set in COMPARATOR, PRECHECK and ENVELOPE Screen after a
weld sequence has ended or when a trouble occurs in an operation.
(An error output signal, NG or Caution can be switched at the setting in
6.(9)③ERROR SETTING Screen.)
The operation stays stopped at the occurrence of an error until the
reset signal is input.
The output manner can be selected at the setting of NG OUTPUT in
6.(9)②STATUS (2/2) Screen.
NORMALLY CLOSE
The Pin is closed with the power turned on, but becomes open with
an error occurring.
NORMALLY OPEN
The Pin is closed with an error occurring.
The rated capacity of a contact is 24VDC 20mA (Semi-conductor
switch used).
25
END Signal Output Terminal.
After the sequence has ended, the Pin is closed for the certain period.
The period of closing can be set to HOLD, 10ms or 100ms.
The signal also is output when the sequence is made operate in the
condition of WELD OFF. The rated capacity of a contact is 24VDC
20mA (Semi-conductor switch used).
26
CAUTION Signal Output Terminal.
When ON is set at ERROR SETTING Screen, NG Signal can be
switched to Caution Signal. The Pin is closed after the weld sequence
has ended. Even if Caution Signal is generated, the welding operation
can be continued.
Input a reset signal or start signal for releasing Caution Signal.
The rated capacity of a contact is 24VDC 20mA (Semi-conductor
switch used).
