Exceptions
The optional fuel level switch must
be installed.
Description
If the unit is a rail application, this
feature is ENABLED. When the optional customer
fuel level switch closes (supplies chassis ground to
the microprocessor fuel level input), the unit will
enter a fuel conserve mode. If the unit is not a rail
application this feature should be DISABLED.

Exceptions
Only available if RAIL OPTION is
ENABLED.
Description
This option changes the alerts
criteria, defrost allowed temperature and defrost
termination temperature. It should only be used
when specified by the customer.
If rail alternate is
enabled a defrost cycle is allowed with an
evaporator coil temperature less than or equal to 50
°F (10°C) and terminates at 65°F (18°C).
Blocked Air Chute Detect
Micro Rev

HMI Rev
All
Choices
ENABLED or DISABLED
Factory Set
DISABLED
Exceptions
The optional Spare Sensor 1 must
be installed.
Description
The Air Chute Detect feature is
designed to detect a blocked or improperly installed
trailer air chute. Spare sensor 1 is located at the
rear of the trailer and directly in the air flow at the
end of the chute. The temperature detected by this
sensor is compared to the temperature detected by
the control discharge air temperature sensor. This
feature functions only during cool mode operation.
If this temperature differential exceeds a user
defined number of degrees for a user defined period
of time, Alarm Code 46 CHECK AIR FLOW is
generated as a check alarm. If the trailer is
equipped with a door switch and the feature is
enabled, monitoring ceases when the door is
opened and is resumed 45 minutes after the door is
closed. When the unit enters a defrost cycle,
monitoring ceases and is resumed 45 minutes after
the defrost cycle terminates. Should the control
discharge temperature sensor or Spare sensor 1 fail
the Air Chute Detect feature is disabled.

Choices
1°F to 20°F in 0.1°F increments
1°C to 10°C in 0.1°C increments
Factory Set
9.9°F (5.5°C)
Exceptions
Only available if BLOCKED AIR
CHUTE DETECT is ENABLED.
Description
This feature selects the temperature
differential, from the front to the back of the trailer
that must be exceeded to cause an alarm to occur.
The temperature differential is calculated using the
control discharge air sensor and spare sensor 1.
This temperature differential must exist for the time
specified by TIME TO ALARM below in order to set
Alarm Code 46 Check Air Flow.
