When the contact is "Closed", "Run" is to be inputted.
Input SPEC: No-voltage "a" contact (When the applied voltage is 20 to 30V DC and the contact is "Closed",
the welding current is approx. 10mA.)
For input, use a contact for micro current. (12V DC, 1mA max.)
Operation input
Abnormal input
When the contact is "Open" or "Closed", "Error" is produced. For changeover, refer to 2. Initial Setting
Input specifications: No-voltage "a" contact (The welding current is approx. 10mA when the applied voltage is 20
to 30V DC and the contact is "Closed".)
For input, use the contact for micro current. (12V DC, 1mA max.)
When the switch was set to "Ins." (Instantaneous Output), the operation input terminals M3, M4 and abnormal
input terminals A3, A4 are not used.
Terminal used in case where the switch was set to "Continuous Output" (Con.) or "Instantaneous Output" (Ins.)
When the switch was set to "Ins." (Instantaneous Output), the operation input terminals M3, M4 and
abnormal input terminals A3, A4 are not used.
Power Supply & Earth Wiring
•
For power supply, 1~200-240V is used. The wiring to the power terminal block (L/N) is required.
The electric wire used should be 1.25 to 2.0mm
2
.
After checking the power supply specifications, make correct connections.
•
Connect the earth wiring to the " " terminal. Use a 2.0mm
2
wire.
