• UNIT CONTROL: Engine Operation: Refrigeration system shutdown and alarm. 

Electric Operation: Refrigeration system shutdown and alarm with PSCON still ener-
gized. 

• RESET CONDITION: Auto reset after 15 minutes or alarm may be manually reset via keypad or by turn-

ing the 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. 

CORRECTIVE ACTIONS:

1.

Perform

 

Pretrip

 

Clear Active Alarm list, then run Pretrip & check for any new alarms. Any active alarms must be cor-
rected and cleared before proceeding. 

2.

Check Configurations for Correct Maximum Amps

 

Settings

 

a. Check DIESEL MAX GEN AMPS configuration setting. Setting should be 24 - 25 Amps. Maximum

recommended setting is 25 Amps. Minimum recommended setting is 22 Amps. 

b. Check STANDBY MAX GEN AMPS configuration setting. Setting should be 22 - 25 Amps. Maxi-

mum recommended setting is 25 Amps. Minimum recommended setting is 22 Amps. 

c. Check STARTUP MAX AMPS configuration setting. Setting should be 15 - 19 Amps. Maximum

recommended setting is 19 Amps. 

d. Check DIESEL OFFSET MAX AMPS configuration setting. Setting should be 4 Amps. 

3.

Check For Electrical Failure

 

In System

 

a. Check electrical motors. Visually inspect condenser fans and evaporator fan for damage to motor

or fan blade, or for foreign material obstructing the movement of the fan. Listen for noise caused
by failed bearing or motor obstruction. 

b. Check for defective wiring. Check for discolored wiring at contactors and loose connections. 

c. Check for defective contactor. Remove and replace any suspected contactor(s).
