DESCRIPTION RECOMMENDED ACTIONS
External 1-16 1-16 These are the optional additional External
Faults available when there is an additional
XIO board installed. This is configured with
XIO Ext Faults (P593), and this message
will appear if the specific input (1-16) is
configured in Fault Config as a Warning.
– See associated Fault Description
Fan On 30 The drive control is receiving a hardwired
fan feedback even though the fan has not
been commanded to run.
– Check Fan feedback wiring and confirm
with ED
Fan 1 Loss 31 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
Fan 2 Loss 32 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
Fan1 ContctrOpen 22 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 Air
Pressure faults to fault the drive.
– If the drive faults, investigate problems
with the fan contactors or the fan
overloads
– If the drive is still running with this
warning, there is a problem with the
Fan Isolation Switch auxiliary
Fan2 ContctrOpen 199 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.
Gate Test Pwr On 119 The gating harness is plugged into the
DC/DC power supply, and the drive has
detected some current flow – This will occur whenever attempting a
gating test
– If there is no gating harness installed,
replace the DC/DC power supply
Gnrl IO Config 127 The XIO card which was being assigned to
the General I/O is not a card which can be
used for this purpose.
– Select the proper slot containing the XIO
card which is compatible for General I/O
usage using XIO General Input/Output
(P592)
Gnrl IO Conflict 128 The XIO card previously being used for
General I/O has been reassigned for
another purpose. – Check the configuration of all XIO slots
using XIO General Input/Output (P592)
and XIO External Faults (P593), and
reassign if necessary.
Ground Differ 160 This represents an excessive difference
between the Analog and the Digital grounds,
measured on the CIB Board
– This could be a problem with the
grounding in the drive system
– Verify grounds are per the drawings
– Replace CIB to eliminate board as a
problem
– Contact Factory if problem persists
