CAUSE
MEASURES
E-01
SYSTEM
ERROR
Error has been detected on the unit
Recycle power. If E-01 SYSTEM ERROR
is displayed once again, repair is required.
Contact Amada Weld Tech.
E-02
MEMORY
ERROR
The welding schedule data is different
from the programmed schedule.
Check all of the settings. If the data in
memory is damaged, the following are
possible causes:
•
Power surge or electrostatic noise
•
Flash memory’s rewrite limit has been
exceeded
•
If error occurs again after initialization,
the Power Supply will need repair.
Contact Amada Weld Tech.
E-03
MEMORY
TROUBLE
E-04
PARITY
ERROR
Cable to input start signal is broken, and
a parity check error is detected.
Check start signal input cable.
E-05
TRIP OF
EXTERNAL
THERMO
Temperature of welding transformer rises
and external thermostat input circuit
opens.
Lower the 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
Internal temperature of equipment rises
and thermostat for the power transistor in
the power module is 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 the welding electrode
adequately.
SQD
or
SQZ
time is too short.
Check
SQD
or
SQZ
time setting to
determine whether it is too short. (Set
SQD
or
SQZ
time > 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.
