Running Pretrip
A Running Pretrip occurs when Pretrip is initiated after the
engine or electric motor is running. The Running Pretrip test
proceeds in the order shown below:
•
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.
Pretrip Test Issues
When performing a Pretrip Test, the following issues should be
considered.
•
If running a Pretrip Test on a trailer loaded with dry cargo,
insure that proper airflow can occur around the load. If the
load restricts airflow, false test results may occur. Also,
SR-2 units have high refrigeration capacity which results
in rapid temperature changes. Sensitive dry cargo may be
damaged as a result.
•
If running a Pretrip Test on a trailer that has just been
washed down, the extremely high humidity inside the
trailer may result in false test results.
•
If running a Pretrip Test on a trailer loaded with sensitive
cargo, monitor the load temperature during the test as
normal temperature control is suspended during pre-trip
operation.
•
Always perform Pretrip Tests with the trailer cargo doors
closed to prevent false test failures.
