CHAPTER 5: MAINTENANCE
125ADP/300ADP/1000ADP DUAL PULSE RESISTANCE WELDING POWER SUPPLY
990-922 5-3
Error Number Error Name Description Troubleshooting steps
2 Capacitor Charge timeout
The capacitors did not reach the
programmed energy level within 500
msec.
1) Verify that the AC line
voltage is within limits.
2) If the AC voltage is
within limits and the
error persists, contact
Amada Miyachi
America for service.
3 Firing Switch timeout
The firing switch did not close
within 10 seconds of FS2 closing.
Adjust the weldhead and/or
parts to be welded so that
the firing switch closes
within 10 seconds of FS2
closing.
4
Calibration value out of
limits The value of the capacitance entered
during calibration is out of limits.
Contact Amada Miyachi
America for service.
5 Memory write error.
The internal memory writing process
did not complete within 1 second
Contact Amada Miyachi
America for service.
6 Memory error
The values stored in memory have
been corrupted. Default values have
been reloaded into the unit.

America for service
8
Internal communication
error
An error occurred in the internal
communication between the front
panel and control board.
Contact Amada Miyachi
America for service
10 E-stop error The emergency stop input is open
Close the emergency stop
switch
11 Chaining error
An error happened in a chaining
sequence
1) Reset the chaining
sequence to the first
schedule in the chain
2) If the error persists,
contact Amada Miyachi
America for service
12 Open load detected
The resistance of the secondary
circuit is too high.
1) Verify that the
weldhead is closed
when the unit fires.
2) Verify that the weld
cables are tightly
connected
3) Verify that the electrode
is properly installed in
the weldhead
If the process requires
operation with a high
secondary circuit
resistance, contact Amada
Miyachi America for
assistance
