Err
Code
Description Possible Cause Things to Check Correction
372 Monitor will not
disable high voltage
during POST
POST has determined that
the Monitor cannot disable
the HVPS.
The ribbon cable providing
control to the HVPS is not
properly connected.
Verify that all cables are properly
connected.
Configure the system for test
mode operation and verify prop-
er voltages on HV_MON.
Cycle system power and deter-
mine if this error is repeated.
Repair or replace the
HVPS.
Replace the
Controller assembly.
373 Damping cir-
cuit failed POST
– damping not
detected.
The Monitor detected a
failure in the RF Amplifier
damping drive signal during
POST.
Configure system for test mode
operation.
Verify that the RFDAMP_DR
signal switches high immediately
preceding each RF Drive pulse
and switches low following each
RF Drive pulse while activat-
ing in Spray or Standard Coag
modes.
Verify correct operation of the
damping circuitry on the RF
Amplifier.
Repair or replace
the RF Amplifier
assembly.
Replace the
Controller assembly.
374 Damping circuit
failed POST –
damping stuck on,
The Monitor detected a
failure in the RF Amplifier
damping drive signal during
POST.
No RF output.
Verify that all internal cables are
properly connected.
Configure system for test mode
operation.
Verify that the RFDAMP_DR
signal switches high immediately
preceding each RF Drive pulse
and switches low following each
RF Drive pulse while activat-
ing in Spray or Standard Coag
modes.
Repair or replace the
RF Amplifier assem-
bly. Q1 may have
failed.
Replace the
Controller assembly.
379 RF calibration
failed POST
System calibration required
on one or more modes.
Recalibrate the system.
Configure the system for test
mode operation and cycle power.
Measure the actual power into a
fixed load.
If power is correct, verify proper
operation of the Monitor voltage
and current sensing circuits.
If power is correct, verify proper
operation of the RF Controller
voltage and current sensing cir-
cuits, the HVPS, and the RF
Amplifier.
Replace the
Controller assembly
if the system will not
calibrate.
