00053 BOX TEMP OUT-OF-RANGE
• ACTIVATION:
Condition One: If the unit is running in Pulldown and the SAT is not greater than 1°F (0.56°C) below
the RAT or if the unit is running in Pull-Up and the SAT is not above the RAT, the configured action
(Alarm only after 30 minutes or Alarm and Shutdown after 45 minutes) will be activated.
NOTE
If the Out-Of-Range Alarm Functional Parameter is set to OFF, the following conditions will not trig-
ger an alarm or shutdown.
Condition Two: If the refrigerated compartment temperature has been within ± 2.7°F (± 1.5°C) for
perishable setpoints or + 2.7°F (± 1.5°C) for frozen of setpoint at least once since the unit was
started and is now further away from setpoint than the limit set in the Out-Of-Range Alarm Func-
tional Parameter [4°, 5°, or 7°F (2°, 3°, or 4°C)], the configured action (Alarm only after 30 minutes
or Alarm and Shutdown after 45 minutes) will be activated.
Condition Three: If a shutdown alarm occurs and the RAT is further away from setpoint than the limit
set in the Out-Of-Range Alarm Functional Parameter [4°, 5°, or 7°F (2°, 3°, or 4°C)], the configured
action (Alarm only after 30 minutes or Alarm and Shutdown after 45 minutes) will be activated
regardless if the refrigerated compartment temperature has been in-range or not.
• UNIT CONTROL: Engine and Electric Operation: If the microprocessor is not configured for shutdown,
alarm only. If the microprocessor is configured for shutdown the unit will shutdown and alarm.
• RESET CONDITION:
Condition 1: Auto reset; If the unit is running in Pulldown and the SAT is greater than 1°F (0.56°C)
below the RAT or if the unit is running in Pull-Up and the SAT is greater than the RAT.
Condition 2 & 3: Auto reset when the temperature is within ±2.7°F (±1.5°C) for perishable setpoints
or + 2.7°F (± 1.5°C) for frozen setpoint.
For Any Condition: alarm may be manually reset using the display mounted keys OR by turning the
unit off, then back on again.
NOTE: The 30 or 45 minute timer is reset and starts again whenever:
• The unit cycles off and restarts in Start-Stop.
• The unit goes into and comes out of Defrost.
NOTE: This alarm does not go into the Inactive alarm List when it becomes inactive or is cleared.
NOTE: This alarm will not be activated in Sleep Mode.
NOTE: For Condition Two, the temperature criteria for this alarm is reset, and the refrigerated compartment
temperature must again go In Range before this alarm can be activated if any of the following occur:
• Pretrip is started.
• Setpoint is changed.
• A door switch or remote switch is installed and configured as a door switch, and the switch is opened indi-
cating that the compartment door has been opened.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, clear the
alarm(s). (Refer to Note 1 in Notes Section, page 7-2.) Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1. Check Compartment Doors
Inspect all compartment doors. Must be closed, and not allowing any air leakage.
2. Defrost Evaporator
Initiate manual defrost cycle. Must terminate automatically. Verify all ice cleared from evaporator coil.
