WARNING
CODE
DESCRIPTION RECOMMENDED ACTIONS
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 Conv AirFlow
Warning Value (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) – Clean as
required
– Improper Alarm settings – Verify Pressure
Value voltage level when running with
clear air flow, and compare to expected
values for that specific drive type
– Verify Alarm and Trip set-up procedure
was completed adequately and adjust as
necessary
– Verify for drives with external ducting that
there is sufficient air to the drive input
– Verify supply voltage to differential
pressure transducer at ACB and confirm
output is stable
Convrtr FansOn 206 The drive contol has detected that the
converter fan contactors are closed even
though it has not been commanded to run.
– Check Fan feedback wiring and confirm
with ED
– Verify that XIO is functional.
Convrtr Fan1Loss 208 Drives with a Redundant Fan (P141) 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 Fan 2 is operating with the proper
current levels
– At the next possible shutdown, reset the
warnings and Fan 1 can be run again
Convrtr Fan2Loss 209 Drives with a Redundant Fan (P141) 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 Fan 1 is operating with the proper
current levels
– At the next possible shutdown, reset the
warnings and Fan 2 can be run again
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 Conv AirFlow faults
to fault the drive.
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.
– 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
