Run OD Fan Test Procedure
The OD Fan Test sends a high-speed
command signal to the OD fan motor
and can be used to verify motor and
control operations.
If the OD Fan motor does not run:
1. Verify fan blades are free from obstruction
and motor turns freely.
2. Confirm high voltage to OD Fan is present
and in range (187VAC-252VAC).
3. Confirm high voltage leads are connected
and not damaged.
4. Confirm motor is receiving a PWM signal
by measuring DC Volts at plug J9 on the
IVCS. High speed fan signal should
measure between 15-18 Volts DC.
5. Confirm PWM motor plug (J9) and leads
are connected and not damaged.
With all inputs and conditions verified,
motor is defective.

Drive Test Notes
1. Drive Diagnostics forces a shutdown and waits
until compressor is completely coasted before
running the drive diagnostic routine.
2. The OD system will enter a hard lockout state to
ensure no other system component is attempting
to run.
3. Show “TESTING” while internal diagnostics are
being performed (about 30 seconds).
4. One of five conclusions will be displayed at the
end of the Drive Test as a result of running the
test.
5. At the conclusion of this test, the results screen
will remain displayed until power is cycled or the
Exit Drive Test option is used.
6. If Drive Test result is “Passed No Fault” the
compressor will run for one minute.
7. The user will then have the ability to scroll up or
down to visit an Exit Drive Test screen. Exiting the
Drive Test will reset the IVSC software and clear
the hard lockout state.
8. If the Drive Diagnostic test is not exited, a 2 hour
timer will be kept, and upon expiration of that
timer the IVSC will automatically reset itself.
