Fault Code

Fault Code Section
All fault codes also illuminate the fault symbol.
1. E001, Over Temp.
E001 illuminates the temperature symbol as well as the fault symbol. A temperature fault that is not due to
exceeding the duty cycle, i.e. shows up at power on or soon after, is likely a hardware problem. Temperature is
measured on the heatsink of both the PFC board and the Inverter board.
a. Rev AB Inverter board requires J606 be a jumper. Confirm it is in place. Later revisions will eliminate the
need for the jumper.
b. Confirm that J800 and J610 are plugged in to the PFC and the Inverter boards. Not plugged in will cause
the fault. Measure J800-6 (+) to GND_PRI. Normally about 14V, if so PFC board is OK. If J800-6 is low
skip to "d."
c. Problem could be the ribbon cable /OVERTEMP signal on pin 19 shorted to pin 18 (GND). Disconnect
both ends of the ribbon cable and measure for open circuit between pins 18 and 19.
d. Either the PFC or the Inverter board can pull J800-6 low. Only way to tell which is to remove the wire
from J800-6 using an EXTRACTION TOOL #11-03-0044 from Molex. After removing the wire, if E001
remains, replace the Inverter board. If E001 goes away replace the PFC board.
2. E002, Input Fault
Circuits on the Bias board measure the incoming AC voltage plus the boosted DC voltage on the bulk capacitors.
Bias Supply board jumpers set wrong, AC voltage that is too low or sags when loaded with increased current
during transfer, or is missing a phase if unit is 3 phase, will set the fault. Also a defective PFC board.
!
It is normal for E002 to show during power down as input voltage has been removed but the control power
remains for a few seconds.
a. The jumpers at J300 must be set according to if the unit is single phase or 3 phase as shown on the System
Schematic. Confirm they are set right.

CAUTION
Single phase and 3 phase PFC boards are different, have different
catalog numbers! Using the wrong one may cause it to fail
