Function Test
The MP-3000a 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.
NOTE: The Function Test does not test the
actual performance of the complete system.
Therefore it is not a Pretrip test and should not
be used instead of the PTI Test.
With the unit On/Off switch ON and the LCD
display showing the standard display (setpoint):
1. Press F3 key to enter the menu list.
Repeatedly press F2 key to scroll through
Main Menu until “COMMANDS” appears in
LCD display.
2. Press F4 key to access the Commands menu.
The first command in the submenu appears in
the LCD display.
3. Press F2 or F3 key to scroll to Function Test.
4. Press F4 key to start the Function Test. LCD
display shows functional test currently being
performed. Function test ends automatically.
Unit automatically returns to normal
operation. See “CRR Function Test” on page
82.
