MAINTENANCE
Section I: Troubleshooting
The table below lists the
ERROR
messages that may be displayed on the Pendant and what those messages
mean, and corrective actions you can take.
FAULT
CODE
CONTENTS CAUSE MEASURES
E-01 SYSTEM ERROR
Error has been detected in the
IS-2200CA/4500CA
Re-cycle the power. If the E-01 SYSTEM
ERROR is displayed again, repair is required.
Contact AMADA WELD TECH.
E-02
MEMORY
ERROR
The welding schedule data is different than
the programmed schedule.
Check all the settings. If the data in memory is
corrupt, the possible causes are:
Abnormal Power Supply voltage from power
surge or electrostatic discharge
Flash memory’s rewrite limit has been
exceeded
If the error occurs again after initialization, the
Power Supply will need repair. Contact
AMADA WELD TECH.
E-03
MEMORY
TROUBLE
E-04 PARITY ERROR
Input “Start” signal cable is open/broken,
and a parity check error is detected.
Check start signal input cable.
E-05
TRIP OF
EXTERNAL
THERMO
Welding transformer temperature rises and
opens the external thermostat input circuit.
Lower transformer temperature. When using a
water-cooled transformer, properly adjust the
temperature and flow rate of the cooling water.
External signal input power is not
connected. Check external input signal for proper
connection.
E-06
TRIP OF
INTERNAL
THERMO
High equipment temperature causing the
power transistor thermostat to open.
Ensure that the duty cycle does not exceed the
specified value.
E-07 NO CURRENT
Squeeze of welding electrode is not
sufficient.
Adjust the squeeze of welding electrode.
SQD or SQZ time is too short.
Check the setting of the SQD or SQZ time to
determine whether it is too short. (Note: Set the
SQD or SQZ time to a period longer than the
stroke time of the electrode).
NO CURRENT LEVEL is high.
Set a lower NO CURRENT LEVEL .
Fuse inside the equipment is blown.
The fuse needs replacement. Contact AMADA
WELD TECH.
Toroidal coil is not connected. Connect the toroidal coil.
E-08
OUT LIMIT OF
CURRENT
ERROR Welding current is out of CURRENT
setting range on the MONITOR SET
screen.
Check for stained welding electrode or loose
cable connection.
