NOTE:
1. Warning or Alarm is determined by the setting of the reference
Parameter.
Troubleshooting
The Carrier Controller software offers several tools to assist
with troubleshooting unit issues.
BLACK BOX FUNCTION
The control system is equipped with a “black box” function that
continuously stores operating parameters in the onboard memory
every 5 seconds. For each alarm event that is triggered, the system
collects up to 180 records (15 minutes) of data, with approximate-
ly 14 minutes of data recorded before the alarm is triggered and 1
minute of data after. The black box function is capable of storing
20 events of data on a rotating basis (first in first out). This file can
be accessed by using the Carrier Service Tools; contact your Carri-
er representative for assistance. See Tables 172 and 173.

NOTE 1
Speed Limit
When the speed is outside of the specified
range in parameter 4-12 Motor Speed Low
Limit [Hz] and parameter 4-14 Motor Speed
High Limit [Hz], the frequency converter
shows a warning. When the speed is below
the specified limit in parameter 1-87 Trip
Speed Low [Hz](except when starting or
stopping), the frequency converter trips

The current is higher than the value in
parameter 4-18 Current Limit.
Ensure that motor data in parameters 1–20 to 1–
25 are set correctly. Contact Carrier Service

Temperature
The temperature limit of the control card
has been exceeded
•
Check that the ambient operating temperature
is within the limits.
•
Check for clogged filters.
•
Check the fan operation.

Check the control card
066
Warning
Heat Sink
Temperature Low
The frequency converter is too cold to
operate. This warning is based on the
temperature sensor in the IGBT module
Confirm that the VFD heater is working properly
by checking voltage across the heater terminals,
120V should be present at low temperatures
which would trigger this warning

Warning/
Alarm
Heat Sink
Temperature
This alarm is generated by the Variable Fre-
quency Drive. The alarm will be generated if
the maximum temperature of the heat sink
has been exceeded. The temperature fault
cannot reset until the temperature drops
below a defined heat sink temperature. The
trip and reset points are different based on
the power size. This alarm is equivalent to
A29 - Heat Sink Temp.
The circuit is
shut down or not
allowed to start.
Automatic, after heat sink temperature falls below
a preset point.
