(1) Fault Code List
In the event of a problem with the Power Supply, the MA-660A displays the fault
code and message.
In such cases, read this section carefully, then inspect the equipment and take the
necessary countermeasures. If you have any questions, consult us or your
distributor.
Fault
code
Error message Cause Measures
E-01
SYSTEM
ERROR
Error has been detected on IS-300A.
Once turn off power and turn on
again. If E-01 SYSTEM ERROR is
displayed again, repair is required.
Contact us.
E-02
MEMORY
ERROR
The welding schedule data is
different from the programmed one.
Check all the settings. If the data in
memory is damaged, the following
are possible causes:
 Generation of powerful power
supply or electrostatic noise
 Abnormal supply voltage
resulting, for example, from
lightening or induced lightening
If the error occurs again after
initialization, the Power Supply
needs repair. Contact us.
 Occurrence of an error when a
schedule is copied (E-03 only)
Perform a schedule copy again.
It would be useful to record the
settings in preparation for data
damage. To print the settings, use
14. Schedule Data Table.
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 temperature of transformer.
When using water-cooled
transformer, properly adjust
temperature and flow rate of 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 power
transistor in power unit is open.
Ensure that the duty cycle does not
exceed the specified value. (See 10.
(3).)
E-07 NO CURRENT
Squeeze of welding electrode is not
sufficient.
Adjust squeeze of welding electrode
adequately.
SQD or SQZ time is too short.
Check setting of SQD or SQZ time
to determine whether it is too short.
(Set 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.
(See 4. (10)(c).)
