Test 2 - 12VDC Electrical Component Amperage Check - Test 2 will check the amperage (current) draw of the fol-
lowing components:

• Battery Amp Draw (All Components Turned Off).

• Liquid Injection Valve

• Condenser Fan Contactor #1

• Condenser Fan Contactor #2

• Evaporator Fan Contactor

• Compressor Contactor

• Standby Contactor #1

• Standby Contactor #2

• Heater #1 Contactor

• Heater #2 Contactor

Each component will be individually checked for proper current draw. An alarm will be activated for any component
not drawing amperage in the expected range.

Test 3 - Temperature Sensor Check

- Check the condition of all of the system temperature sensors. Test 3 will

last approximately 5 seconds. If a problem is detected with any of the sensors, the corresponding alarm will be acti-
vated. Refer to Alarm

Section 7.3

Test 7 - Electric Heater Amperage Check

- Each heater will be energized individually and checked for proper cur-

rent draw. An alarm will be activated for any heater not drawing amperage in the expected range;

P00187 CHECK

HEATER 1 CIRCUIT

P00188 CHECK HEATER 2 CIRCUIT

Test 8 - Evaporator Fan Motor

- The evaporator motor contactor will be energized and the motor checked for

proper current draw. Alarm

P00188 CHECK HEATER 2 CIRCUIT

will be activated if the evaporator fan motor is not

drawing amperage in the expected range.

Test 9 - Condenser Fan Motors

- The condenser fan motor contactors will be energized and the motors checked

for proper current draw. Alarm

P00190 CHECK CONDENSER FAN MOTOR

P11000 CHECK CONDENSER

FAN MOTOR 2

will be activated if a condenser fan motor is not drawing amperage in the expected range.

Test 10 - Check Suction Modulation Valve (CSMV)

- This test is run to ensure that the CSMV is opening and

closing properly. If suction pressure doesn’t change as expected with CSMV closed, then alarm

P00180 CHECK

SUCTION MOD VALVE

will be displayed.

Test 11 - Evaporator Expansion Valve (EVXV)

- This test is an operational check of the EVXV. If evaporator outlet

pressure doesn’t change as expected with the EVXV closed then alarm

P00177 CHECK EXV (EVXV) SUPER-

HEAT

will be displayed.

Test 12 - Economizer Expansion Valve (ECXV)

- This test is an operational check of the ECXV. If economizer

outlet pressure doesn’t change as expected with the ECXV closed then alarm

P00173 CHECK ECONOMIZER

will

be displayed.

Test 13 - Liquid Injection Solenoid Valve (LIV)

- This test checks the operation of the liquid injection solenoid

valve. If compressor suction temperature does not change when LIV is energized, alarm

P00179 CHECK LIV

will

be displayed.

Pretrip Termination

- When the Pretrip cycle is completed, the unit will return to normal temperature control oper-

ation. “PRETRIP PASS” will be displayed until the operator presses the EXIT key. In the event that the Pretrip test
activates an alarm(s), either “PRETRIP FAIL & COMPLETE” (if the entire Pretrip cycle was completed), or “PRE-
TRIP FAIL IN TEST XX”, (if the Pretrip cycle was aborted by an alarm before it was completed) will be displayed.
