Name Description Corrective action
181
Metering 
console CAN 
time-out
Auto Gas
Only
The power supply did not 
receive a CAN message 
from the metering 
console within 1 second.
1.  Verify that the power supply-to-metering console 
CONTROL and POWER cables are not damaged and are 
properly connected to PCB3, and the rear of the metering 
console.
2.  Verify that D17 (+5 VDC) and D18 (+3.3 VDC) are 
illuminated on PCB2 inside the metering console. These 
LEDs indicate power to PCB2. Also verify that D26 
(CAN – RX) and D27 (CAN – TX) are illuminated on 
PCB2 inside the metering console. These LEDs indicate 
communication between the metering console and the 
power supply.
3.  If power is present at PCB2 and PCB3 and both metering 
console cables are good, then PCB2 or PCB3 has failed. 
Use the CAN tester to verify which board needs to be 
replaced.
4.  Verify that the gas console control PCB and power 
distribution PCBs are securely mounted to the chassis at 
all four corners.
182
Secondary 
power supply 
time-out
HPR800XD
Only
The secondary power 
supply fails before 
transmitting the error to 
the primary power supply.
1.  The primary power supply to secondary power supply CAN 
communication cable was disconnected after power-up. 
2.  The cable has electrical interference (noise) or the cable 
shielding has been compromised.
298
Secondary 
power supply 
phase loss at 
initialization 
HPR800XD
Only
The system detected 
incoming line voltage 
during power-up, before 
the contactor was 
energized.
1. Verify phase-to-phase voltage to power supply.
2.  Disconnect power to power supply, remove cover on 
contactor and inspect contacts for excessive wear.
3.  Inspect power cord, contactor, and input to chopper for 
loose connections. 
4.  Inspect phase loss fuses on Power Distribution board. 
Replace board if fuses are blown.
5. Perform phase loss test (see Maintenance section).
383
No ramp-up 
message
HPR800XD
Only
The secondary power 
supply is ready to provide 
current output but does 
not receive the control 
signal from the primary 
power supply.
1  Turn off the power to the system and then turn on the 
power again. 
2.  The cable has electrical interference (noise) or the cable 
shielding has been compromised.
