PTI (Full Pretrip) Test
NOTE: Units equipped with a water-cooled
condenser must be set to operate on air-cooled
condensing to perform a complete system
capacity test.
The MP-3000a controller contains a special Full
PTI pretrip test that automatically checks unit
refrigeration capacity, heating capacity,
temperature control, and individual components
including the controller display, contactors, fans,
protection devices and sensors. The test includes
measurement of component power consumption
and compares test results to expected values. The
test takes up to 2 to 2.5 hours to complete,
depending on the container and ambient
temperature.
NOTE: Correct all existing alarm conditions
and clear the alarm codes before performing a
Full PTI test. The controller will automatically
clear all existing alarms before beginning the
Full PTI test.
