RECOMMENDED ACTIONS
Input CtctrOpen
184
The input contactor is open even though it
has been commanded to close. Verify the
contactor feedback and the 120V wiring to
the ACB. Drive may be in auto-restart mode
following loss of medium voltage.
Input CtctrClsd
185
The input contactor is closed even though it
has been commanded to open. Verify
normal mode of starter the contactor
feedback and the 120V wiring to the ACB.
–
Ensure the associated starter unit is set
to Normal mode
–
Verify the feedback from the contactor
status (normally control relay auxiliary
and contactor mechanical auxiliary) is
wired properly and powered
–
Verify that there is control power to the
contactor
–
Verify the associated ACB I/O
–
Verify that the Holding Coil or Closing
Coil is not shorted
–
Review Contactor control wiring
–
These warnings may also occur during
the autorestart feature, as the loss of
power may also result in the inability to
hold in the contactor during the outage
Input IsoSwOpen
190
The input isolation switch is open when it is
expected to be closed. The switch should be
closed in all operating modes of the drive
except System and Gate Test. Ensure
proper positioning, wiring feedback to ACB,
mech auxiliary setup.
Input IsoSwClsd
193
The input isolation switch is closed when it
is expected to be open. The switch should
be open in System and Gate Test. Ensure
proper positioning, wiring feedback to ACB,
mech auxiliary setup.
–
In DC Current test modes, the isolation
switches are expected to be closed for
DC Current test; although only the input
contactor is required the test will run with
warnings if the switches are open
–
Ensure the isolation switches are in the
proper position for the specific operating
mode (Refer to the description of the
Parameter 141 – Hardware Option1 in
the parameters manual)
–
Verify wiring feedback
–
Verify isolation switch mechanical
auxiliary setup
InvHSnk FbrOptic
220
While Running, the Fiber Optic signal from
the TFB on the Inverter Heatsink, connected
to Channel A fiber optic receiver RX7 on
FOI-M-A is not present. This is only a fault
while not running. If this occurs while
running it will appear as a warning.
–
Check TFB and FOI board for power
–
Check the Fiber Optic cables are
properly seated in the transmitters and
receivers
–
Check the fiber optic cable for kinks,
bends, breaks that could be blocking the
signal
–
This can occur if the sensor is not
connected to the TFB
–
NOTE: This is a warning because the
drive should not fault on the loss of the
signal while running. There is no
imminent danger to the drive, but the
user needs to be aware that there is a
temperature feedback signal missing.
