failure per pre--trip Alarm. Ohm test component per
Section 2.13
Listen for noise caused by failed bearing or motor
obstruction
b. Defective wiring
Check for discolored wiring at contactors and loose
connections
c. Defective contactor
Remove and replace suspected contactor
2.
Defective Overload Protector
a. Wrong setting
Readjust setting to 30 amps
3.
Defective Current Sensor
a. Reads too high
Remove and replace
4.
Check Generator Voltage (If Used When Alarm Occurred)
a. Check voltage at GENCON L1--L2,
L1--L3, L2--L3
Should be 440 to 580 VAC
5.
Check Power Source Voltage (If Used When Alarm Occurred)
a. Check voltage at PSCON L1--L2,
L1--L3, L2--L3
Should be 440 to 580 VAC
6.
Check Voltage Output From Contactors
a. Check voltage at GENCON T1--T2,
T1--T3, T2--T3
Should be 440 to 580 VAC
b. Check voltage at CCON with
compressor operating. T1--T2,
T1--T3, T2--T3
Should be 440 to 580 VAC
7.
Verify AC Current Sensor Accuracy
a. Turn all compartment switches OFF,
and RS ON.
Unit AC Current #1 and #2 reading in Data List must be
0.0
1.0 amp.
