01 LINE VOLT, IDLE
02 LINE VOLT, CUTTING
03 CONTROL BIAS
04 THERMAL (SWITCH OPEN)
05 START ON POWER UP
06 FAIL TO FIRE
error number displays and their meaning for the epp-360 power supply.
error 1
+/- 15% deviation in the idle mode is exceeded.
error 2
Line voltage during cut drops by more than 20 %.
error 3
Problem with the bias supplies on the control board. The +15 and -15 volt supplies are not balanced, board
should be replaced.
error 4
Thermal switch has opened. Unit is disabled until overheated component cools down. Look for fans not
working or restrictions on input or output louvers.
error 5
The start switch from the CNC was already on when the power source was powered up. Unit will not be
functional until start signal is removed and then reapplied.
error 6
Ignition did not take place during the 10 seconds allowed for arc ignition.
note: This should rarely occur since the CNC has a much shorter time allowed for the ignition time and
will reset the power source to idle.
error 7
Not used.
error 8
Electrode current was present before the PWM was enabled. Most likely caused by an electrode to nozzle
short on the torch.
error 9
Open circuit voltage in idle mode was over 40 volts. Possible cause leaky IGBTs, faulty PWM drive.
error 10
Open circuit voltage is over 70 volts when unit is powered up. Possible cause leaky IGBT's, faulty PWM.
error 11
Not used.
error 12
Shut down due to single phasing. Fuse blown in supply line circuit.
error 13
Open circuit voltage did not reach 300 volts in the allowed time. Check PWM circuit.
error 14
Ambient temperature exceeded 55 C in control enclosure.
error 15
Bus voltage did not reach 100 volts during the allowed time. Bus charge relay or surge limiting resistors
defective
error 16
Not used
error 17
IGBT driver board error.
error 18
Cutting voltage fell below 70 volts during cutting or below 40 volts during marking.
error 19
Master is requested to engage slave power supply but slave is not present.
error 20
Open circuit voltage detected before PWM was engaged.
error 113
Error detected in slave power supply.
