Error code
number
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
HPR400XD
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
HPR400XD
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.
