Chapter 2 Warning Messages
X X Convrtr AirFlow 204 The pressure drop at the input to the converter section sensed
by the pressure transducer (as a voltage) has dropped below
the value set in AirLoPresure Wrn (P320). This is dependent on
the operation of the main cooling fan.
• Verify fan rotation.
• Check for blocked airflow in the filters/ heatsinks/ ducting (if
installed) and clean as required.
• Improper alarm settings. Verify the pressure value voltage level when
running with clear air flow, and compare to expected values for that
specific drive type.
• Verify that the alarm and trip set-up procedure was completed
adequately and adjust as necessary.
• For drives with external ducting, verify that there is sufficient air to
the drive input.
• Verify supply voltage to differential pressure transducer at ACB and
confirm output is stable.
X X Convrtr FansOn 206 The drive control has detected that the converter fan contactors
are closed even though it has not been commanded to run.
• Check the fan feedback wiring and confirm with the electrical
drawings.
• Verify that XIO is functional.
X X Convrtr Fan1Loss 208 Drives with a redundant fan (specified in Redn ConvFan
HardwareOptions1 [141]) will give this warning if fan 1 is
running, there were no problems with fan 2, and fan 1 is lost.
Fan 2 will start and the drive will continue running.
• Investigate the cause of the fan 1 loss (OL/damaged relay).
• Verify that fan 2 is operating with the proper current levels.
• At the next possible shutdown, reset the warnings and fan 1 can be
run again.
X X Convrtr Fan2Loss 209 Drives with a redundant fan (specified in Redn ConvFan
HardwareOptions1 [141]) will give this warning if fan 2 is
running, there were no problems with fan 1, and fan 2 is lost.
Fan 1 will start and the drive will continue running.
• Investigate the cause of the fan 2 loss (OL/damaged relay).
• Verify that fan 1 is operating with the proper current levels.
• At the next possible shutdown, reset the warnings and fan 2 can be
run again.
X X Conv Fan1 Ctctr 200 This warning indicates that while the drive was running it
detected the loss of the main converter cooling fan. When the
drive is running, the feedback from the fan 1 contactor auxiliary
and isolation switch is lost, but the drive will not trip and wait
for power supply faults or converter air flow faults to fault the
drive.
• If the drive faults, investigate problems with the fan contactors or
the fan overloads.
• Verify the fan contactor, fan overload and the 120V wiring to the
standard XIO card.
• If the drive is still running with this warning, there is a problem
with the fan isolation switch auxiliary.
X X Conv Fan2 Ctctr 201 This warning indicates that while the drive was running it
detected the loss of the redundant converter cooling fan.
When the drive is running, the feedback from the fan 2
contactor auxiliary and isolation switch is lost, but the drive will
not trip and wait for power supply faults or air pressure faults to
fault the drive.
