Pretrip Tests
A Pretrip test verifies unit operation. The Pretrip Menu allows
the operator to select and initiate a Pretrip Test. There are two
different Pretrip Tests, the Full Pretrip and the Running Pretrip.
The Pretrip Tests can be run in either Diesel or Electric mode.
Pretrip Tests are not allowed if:
•
Any alarms are present.
•
The unit is in Sleep mode.
•
Unit is in Service Test Mode, Interface Board Test Mode,
or Evacuation Mode.
Full Pretrip
A Full Pretrip occurs when Pretrip is initiated before the engine
or electric motor starts running. The Full Pretrip test proceeds
in the order shown below:
•
Amp Checks – Each electrical control component is
energized and the current drawn is confirmed to be within
specification.
•
Engine or Electric Motor Start – The engine or electric
will start automatically.
•
Defrost – If the coil temperature is below 45 F (7 C), a
Defrost cycle is initiated.
•
Cool Check – The ability of the unit to cool in low speed is
checked.
•
RPM Check (Diesel Mode only) – If the unit is running in
the Diesel Mode, the engine RPM in high and low speed is
checked during the Cool Check.
•
Heat Check - The ability of the unit to heat in low speed is
checked.
•
Report Test Results – The test results are reported as
“PASS”, “CHECK” or “FAILED” when the Pretrip is
completed. If test results are Check or Failed, alarm codes
will exist to direct the technician to the source of the
problem.
CAUTION: Monitor the return air temperature when
performing a Pretrip Test on a loaded trailer. The
controller may not maintain setpoint during the
Pretrip Test.
