Pin No. Description
4
1ST STAGE Intput Terminal.
Closing of this Pin makes SOL1 Terminal of Pin 32 close.
As the current-supplying sequence does not start, the adjustment or
check of a squeeze location can be done. When closing 2ND STAGE
Terminal at this location, the weld at the optimum squeeze location can
be obtained.
5
2ND STAGE Input Terminal.
Closing the Pin makes the sequence start.
When the sequence works, SOL2 Terminal on Pin 33 is closed.
6
COM Terminal. Internally connected to GND Chassis.
7 to 13
Schedule Input Terminal.
7 = Schedule 1, 8 = Schedule 2, 9 = Schedule 4, 10 = Schedule 8,
11 = Schedule 16, 12 = Schedule 32, 13 = Schedule 64,
When the select method of Schedule is External Schedule Select
Method, they work.
The sum of Schedule No. of closed Pins is corresponding to the
selected Schedule No. (Refer to (3)Schedule No. and Schedule
Select Terminal.)
14
Parity Input or WE1 STOP Input Terminal.
The setting of SCHEDULE# in 6.(9)①STATUS (1/2) Screen allows the
function to be switched.
When EXT. (P) is selected in SCHEDULE#,
Parity Input Terminal.
This Pin makes it possible to detect a trouble caused by the breaking
of a Schedule Select Signal wire. Select Pins so that the sum of the
numbers of closed Schedule Select Signal wires and a Parity Signal
wire may always be odd. (Refer to (3)Schedule No. and Schedule
Select Terminal.)
When EXT. (NP) or PANEL is selected in SCHEDULE#,
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,
It is WE1 Stop Input Terminal.
When this Pin is closed while the sequence works at WE1 (W1), the
sequence skips to COOL (CO).
* In the case of DISPLC**, CURR and VOLT selected at INPUT,
This terminal does not work.
** (only for Displacement Sensor equipped)
15
COM Terminal. Internally connected to GND Chassis.
16
Weld ON/OFF Input Terminal.
Closed circuit is for Weld ON and Open circuit for Weld OFF.
As weld current does not flow even in the activated sequence if the Pin
is open, it can be used at starting for trial.
17
Error and Caution Reset Input Terminal.
When the Pin is closed after eliminating a cause of NG or Caution, a
display of NG or Caution is reset.
18
COM Terminal. Internally connected to GND Chassis.
19
