If the condition continues to exist over an additional period of time a shutdown alarm may occur. If the temperature differential over a period of time indicates the possibility of reduced refrigeration performance a check alarm is generated.
The Alert system monitors the temperature differential and compares it to defined values of temperature differential as determined by setpoint and/or ambient temperature. Thermo King TG-VI Max+, mP-IV+ Smart Reefer, mP-V Whisper The microprocessor monitors the temperature sensors and checks for conditions that may be out of tolerance.

There are 23 individual codes which are cleared by either by turning the unit power switch off and on or by using the Clear Code Screen. The Carrier microprocessor has two levels of alarm codes, Check and Shutdown. The TG-VI Max+ microprocessor has 42 separate alarm codes which are saved until each is individually cleared using the Select and Enter keys. The Thermo King trailer microprocessors utilizes three levels of alarm codes Stored, Check and Shutdown. The mP-IV+ Smart Reefer microprocessor has 59 separate alarm codes and the mP-V Whisper has 61 separate alarm codes which are saved until each is individually cleared using the Code and Clear keys. Thermo King mP-IV+ Smart Reefer, mP-V Whisper If a fault condition is detected the microprocessor will generate and save the appropriate Alarm Code. The operator must monitor the progress of the test and record any malfunctions. The unit will then enter the defrost mode and terminate the Pretrip once the defrost termination switch opens at approximately 50☏ (10☌). The controller will display “PPPP” and the unit will operate in each of the six modes of operation for a period of 30 seconds each. The trailer box temperature must be below 40☏. The unit Pretrip is initiated by depressing the Pretrip key. The Unit Self Check results will remain on the display until any keypad key is pressed. The results are then reported as PASS, CHEC or FAIL. If any problems are encountered the appropriate alarm code(s) will be saved.
Units equipped with modulation are checked to be sure the modulation valve opens and closes. Last, a check is performed to insure the unit can cool and heat by monitoring the rise and/or fall of the coil temperature sensor and comparing to a standard. An RPM check and defrost damper check are next. The Unit Self Check performs a display check and then displays all programmable settings. The Pretrip Test results will remain on the display until any keypad key is pressed. A Defrost check is performed and the unit's status is reported as PASS, CHEC or FAIL. Refrigeration capacity is checked in both cool and heat modes by monitoring temperature differential and comparing to a standard. The microprocessor controller displays all icons, programmable settings and checks engine speed. The unit is then started (may be automatic or manual).

Thermo King Pretrip (mP-IV+ Smart Reefer, mP-V Whisper)Ī Full Pretrip Test will check the current draw of control devices connected to the microprocessor to determine that they are connected and are drawing the proper amount of current. Diagnostics are the microprocessor’s ability to perform internal and external control system self checks to verify unit performance.
