Controller Operation 7-6
Multi-Temp MT µP-IV NOTE: If an alarm is specific to a zone, the appropriate Zone icon also appears in the display.
2. Write down each alarm code that appears. Then correct the cause of each alarm.
NOTE: Turn the Unit On/Off switch OFF to stop unit before inspecting or servicing the unit. Turn the unit Microprocessor
On/Off switch to OFF to service the microprocessor module or disconnect the unit battery. Finally, disconnect the battery to
completely remove 12 Vdc power to the unit for service of the microprocessor relay board and unit controls.
3. To clear the alarms after all problems have been corrected, start the unit. Then press the CODE key to display the alarm again.
4. While the alarm screen is showing, press the CLEAR key. The alarm will clear and the standard display will appear on the
screen. If more than one alarm code is present, repeatedly press the CLEAR key to clear each alarm code individually.
NOTE: Alarms may continue to appear as the unit operates if the alarm condition is not corrected.
Unit Pre-trip Test
The Unit Pre-trip Test automatically performs a functional check of unit operation. The test must be performed with the unit in
Diesel mode and no alarms present. If necessary, turn electric power supply OFF and disconnect power cord. Clear and correct
all alarm conditions before beginning. With the unit set for Diesel operation:
WARNING: Units equipped with a Multi-Temp MT µP-IV or µP-V controller start automatically 10 seconds after the Unit
(Zone 1) On/Off switch is turned ON.
1. Turn the unit (or zone 1) On/Off switch to ON.
2. TCI and SPECTRUM Models: Turn the zone 2 (and zone 3) On/Off switch to ON. Each remote evaporator must be ON to
be tested.
3. Press and hold (at least 3 seconds) the TK LOGO key on the control panel until PrE TRIP (unit Pre-trip prompt) appears in
the display.
NOTE: Press the TK LOGO key before the engine starts to perform a Full CYCLE-SENTRY Pre-trip Test. After the ENTER
key is pressed, PRE AMPS appears on the MT µP-IV display, indicating the amps check is being performed. The amps check
continues for several minutes. Then the unit starts automatically and the controller performs the operating tests.
4. With PrE TRIP in the display, press the ENTER key to start the test.
• “LOAD” will appear in the display for a few seconds.
• The controller then performs a series of unit tests.
• If the ENTER key is not pressed, the operating mode will NOT change and the display will return to the Standard Display
in about 10 seconds.
5. When the Pre-trip Test is complete, the controller displays PASS, CHEC or FAIL. Press any key to clear test results display
from controller.
NOTE: If CHEC or FAIL occurs, view alarm codes and correct all conditions. Then repeat the Unit Self-Check Test. The unit
should PASS before being released for service.
Pre-trip Tests
The controller performs the following checks. Operator attention is not required after the programmable settings have been
displayed.
• Preheat and Start Test: Engine preheats and starts. On Multi-Temp MT µP-IV and µP-V controllers, the TK LOGO key must
be pressed before engine starts to perform Full Pretrip test.
• Display Test: All display segments light at the same time.
• Show Programmable Settings: Controller displays all programmable settings for operator verification.
• RPM Check: Check engine rpm in high and low speed.
• Low Speed Cooling Check: Checks unit cooling performance in low speed.
• Heating Check: Checks unit heating performance.
• Defrost Damper Check: Check damper door operation.
• Low Speed Cooling Check: Second cooling test ensures that unit can cycle between Heat and Cool modes.
• Modulation Check: Checks ability of modulation valve to open and close.
Unit Pre-trip Report
When the Unit Pre-trip is complete, the controller displays the results:
• PASS: Unit passed the test.
• CHEC: Alarm conditions (check or stored alarms) were detected during the test. A dash (-) is displayed in front of these alarms
on the controller display to indicate that they were detected during a Unit Self-Check test.
• FAIL: Shutdown alarm conditions were detected during the test and the controller stopped the unit to prevent possible
damage. The Unit Self Check test was NOT completed.
