Terminal name Explanation
1 WELD STOP To stop the welding on the way, this terminal is closed.
2 START
Welding start input terminal.
The sequence is started by closing this terminal.
3 SCH1
4 SCH2
5 SCH4
6 SCH8
7 SCH16
8 SCH32
9 SCH64
Condition input terminal.
3 = Condition 1, 4 = Condition 2, 5 = Condition 4, 6 = Condition 8,
7 = Condition 16, 8 = Condition 32, 9 = Condition 64
(Refer to SCHEDULE of “6. (6) Schedule Changeover.”)
10 PARITY
Parity input terminal.
A fault due to wire breakage of the condition selection signal can be
detected by this terminal. Perform a setting so that the total of condition
selection signal lines and parity signal close-circuits may be an “odd
number” at all times.
(Refer to SCHEDULE of “6. (6) Schedule Changeover.”)
11 PURGE
When the circuit is closed, the internal solenoid valve is turned on to allow a
gas flow. When the circuit is opened, the solenoid valve is turned off to
stop the gas flow.
12 RESET
Error resetting input terminal.
When the circuit is closed after the cause of the error is removed, the error
is reset.
13 EM_RESET Error resetting input terminal exclusively for an emergency stop error.
16 EM1 Emergency stop 1 input terminal. (*1)
17 EM2 Emergency stop 2 input terminal. (*1)
18 EM2_COM Common of the emergency stop 2 input terminal.
19 EM1_COM Common of the emergency stop 1 input terminal.
20 (Unused) -
21 WELD ON
Welding power ON/OFF changeover input terminal.
When this terminal is closed, WELD ON is executed. (*2)
