MP-5000 Diagnostics

The MP-5000 can be a very helpful diagnostic tool. The following menu areas of the MP-5000 controller will help you diagnose problems occurring with the MAGNUM Plus™ unit.

Alarms and Messages: Displays the code conditions. Alarms and messages are recorded in the controller memory to simplify unit diagnostic procedures. Some alarm codes are only recorded during a Pretrip (PTI) test or function test. Messages are retained by the controller in a non-volatile memory. If the Red LED is on or flashing, enter the Alarms tabular menu to view the alarm.

Brief PTI Test: The MP-5000 controller contains a special Brief PTI pretrip test that automatically checks unit refrigeration capacity, heating capacity, temperature control, and individual components including the controller display, solid state, contactor, fans, protection devices and sensors. The test includes measurement of component power consumption and compares test results to expected values. The test takes about 25-30 minutes to complete, depending on the container and ambient temperature.

Full PTI Test: The MP-5000 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, solid state, contactor, 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.

Functions Test: The MP-5000 controller contains a special function test that automatically tests individual components including the controller display, sensors, condenser fan, evaporator fan, compressors, etc. The test includes measurement of component power consumption and compares test results to expected values.

Manual Functions Test: This menu allows technicians to perform specific diagnostic tests on individual components or turn several components on at the same time to perform a system test.

Values: Displays general unit operating information including temperature values, pressure and air values, internal values, voltage values, digital output and input values, and unit control values.

Data: This menu displays general unit operating information including sensor temperatures, unit electrical data, etc. Refer to the Data Menu in the Operating Instructions Section.
