Code Error number displays and their meaning for the EPP -360 power supply.
01 +/- 15% deviation in the idle mode is exceeded.
02 Line voltage during cut drops by more than 20 %.
03 Problem with the bias supplies on the control board. The +15 and -15 volt supplies are not
balanced, board should be replaced.
04 Thermal switch has opened. Unit is disabled until overheated component cools down. Look
for fans not working or restrictions on input or output louvers
05 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.
06 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.
08 Electrode current was present before the PWM was enabled. Most likely caused by an
electrode to nozzle short on the torch.
09 Open circuit voltage in idle mode was over 40 volts. Possible cause leaky IGBTs, faulty
PWM drive
10 Open circuit voltage is over 70 volts when unit is powered up. Possible cause leaky IGBT’s,
faulty PWM.
12 Shut down due to single phasing. Fuse blown in supply line circuit.
13 Open circuit voltage did not reach 300 volts in the allowed time. Check PWM circuit & E-Stop
on J1.
14 Ambient temperature exceeded 55 C in control enclosure.
15 Bus voltage did not reach 100 volts during the allowed time. Bus charge relay or surge
limiting resistors defective
17 IGBT driver board error.
18 Cutting voltage fell below 70 volts during cutting or below 40 volts during marking.
19 Master is requested to engage slave power supply but slave is not present.
20 Open circuit voltage detected before PWM was engaged.
113 Error detected in slave power supply.
