DESCRIPTION RECOMMENDED ACTIONS
AC/DC#1 DC Fail 143 The output of the specified AC/DC Power
Supply has seen the 56VDC output voltage
drop below the hardwired trip level. The trip
level is fixed in hardware as 52VDC ±
1.7VDC, depending on hardware
tolerances.. All of the outputs of the optional
multiple AC/DC power supplies are
individually monitored and displayed
separately.
– Measure the input voltage and verify it is
within limits
– Measure the output voltage and confirm
whether the output level indeed falls below
the trip level
– Verify fault detection wiring is per the
drawings, and measure the voltage on the
trip signals back to the CIB. The 5VDC is
supplied from the CIB to the fault circuit,
and is pulled low on the power supply
when healthy.
– Verify the internal cooling fan is
operational
– Replace the Power Supply if required
AC/DC#2 DC Fail 144
AC/DC#3 DC Fail 145
AC/DC#4 DC Fail 146
AC/DC#5 DC Fail 147
AC/DC#6 DC Fail 148
AC300 DC Fail 153 Optional for drives with an internal or
external UPS option – The 300W AC/DC
converter specially fed by the UPS has seen
the 56VDC output voltage drop below the
hardwired trip level. The trip level is fixed in
hardware as 51.5VDC ± 1.4VDC,
depending on hardware tolerances.
– Measure the input voltage and verify it is
within limits
– Measure the output voltage and confirm
whether the output level indeed falls below
the trip level
– Verify fault detection wiring is per the
drawings, and measure the voltage on the
trip signals back to the CIB. The 5VDC is
supplied from the CIB to the fault circuit,
and is pulled low on the power supply
when healthy.
– Replace the Power Supply if required
Adapter 1 Loss 309 There has been a loss of communication
between the CIB and the identified
SCANport Adapter (Polled Communication).
The drive will configure the specific Adapter
Loss 1-6 as a fault when the associated bits
in Adapter Loss Mask (P175) is set to a 1.
– Ensure that the SCANport device is
powered
– Verify the SCANport light status and
ensure the device is operating properly
– Verify the customer SCANport network is
properly communicated with the device
– Check CIB LED MOD A status
– Cycle control power to the drive
– Change the Adapter and/or CIB if all
attempts to restore communication fail
Adapter 2 Loss 310
Adapter 3 Loss 311
Adapter 4 Loss 312
Adapter 5 Loss 313
Adapter 6 Loss 314
Adaptr1 ForceFlt 129 There has been a loss of communication
between the identified DPI adapter and the
customer‟s communication network. The
communication between the drive and the
DPI adapter may still be active. This is a
requirement for DPI communications. If the
loss of communication from the network to
the adapter is required to be a warning, this
must be set in the adapter itself, not within
the drive.
– Verify the adapter LED status and ensure
the device is operating properly
– Verify the customer network is properly
communicated with the device
– Check CIB LED status and compare to
the information in Chapter 6 of the User‟s
Manual
– Change the Adapter if all attempts to
restore communication fail
