DESCRIPTION RECOMMENDED ACTIONS
AC/DC#1 DC Fail 95 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. THIS
WILL ONLY APPEAR IF YOU HAVE A
REDUNDANT POWER SUPPLY.
– 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 96
AC/DC#3 DC Fail 97
AC/DC#4 DC Fail 98
AC/DC#5 DC Fail 99
AC/DC#6 DC Fail 100
AC300 AC Fail 103 The AC Fail signal from the 300W AC/DC
power supplies has been activated. This is
treated as a warning since a real loss of this
input voltage will result in a subsequent DC
fail signal. This happens at 85VAC.
– Investigate possibility of loss of input
voltage to the AC/DC Power Supply
– Verify output voltage
– Check alarm signal connections
– Replace Power Supply if necessary.
AC/DC PS AC Fail 102 The AC Fail signal from the 1500W AC/DC
power supplies has been activated. We
treat this as a warning since a real loss of
this input voltage will result in a subsequent
DC fail signal. This will occur at 127VAC L-
L for 3-phase supplies, and 90VAC for
single-phase supplies.
– Investigate possibility of loss of input
voltage to the AC/DC Power Supply
– Verify output voltage
– Check alarm signal connections
– Replace Power Supply if necessary.
Adapter 1 Loss 175 There has been a loss of communication
between the CIB and the identified
SCANport Adapter (Polled Communication).
This will appear as a warning in the drive
when the associated bits in Adapter Loss
Mask (P175) are set to a 0.
– 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 status
– Cycle control power to the drive
– Change the adapter if all attempts to
restore communication fail
Adapter 2 Loss 176
Adapter 3 Loss 177
Adapter 4 Loss 178
Adapter 5 Loss 179
Adapter 6 Loss 180
