Steps
ALARM / CAUSE
CORRECTIVE ACTION
14
ELECTRICAL CIRCUIT
•
TRIGGER–ON: AC Current Sensor 1 is greater than 40A or AC Current Sensor 2 is greater than 40A for
3 seconds
•
UNIT CONTROL: Engine operation: alarm will not activate Standby operation: refrigeration system
•
UNIT CONTROL: Engine operation: alarm will not activate. Standby operation: refrigeration system
shutdown and alarm with PSCON still energized.
•
RESET CONDITION: Auto reset after 15 minutes if the AC current sensor readings are less than
38 amps or alarm may be manually reset via keypad or by turning unit off then back on.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active alarm
should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
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
2.
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
3.
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
4.
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.
5.
Check High Voltage Components Amp Draw
a. Check condenser fan amp draw on all
3 legs.
b. Check evaporator fan motor amp draw
for Compartment 1 on all 3 legs.
c. Check evaporator fan motor amp draw
for Compartment 2 on all 3 legs.
d. Check evaporator fan motor amp draw
for Compartment 3 on all 3 legs.
e. Check compressor amp draw on all
3 legs.
f. Check Compartment 1 Heater amp
draw for HTCON1
See Section 2.13
g. Check Compartment 1 Heater amp
draw for HTCON2
h. Check Compartment 1 Heater amp
draw for 2HTCON1
i. Check Compartment 1 Heater amp
draw for 2HTCON2
j. Check Compartment 1 Heater amp
draw for 3HTCON1
k. Check Compartment 1 Heater amp
draw for3HTCON2
