SAFETY
Your Carrier Transicold refrigeration unit has been designed with
the safety of the operator in mind. During all pre-trip inspections,
daily inspections, and problem troubleshooting, you may be
exposedtomovingparts; pleasestayclear of allmoving partswhen
the unit isin operation and when the Start/Run-Off Switch is in the
START/RUN position.
AUTO-START
YourrefrigerationunitisequippedwithAuto-Startin both Start/Stop
and Continuous Run modes. The unit may start at any time, a
buzzer will sound for 5 seconds before the unit is started. When
performing any check of the refrigeration unit (e.g., checking the
belts, checking the oil), makecertain that the Start/Run-Off Switch
is in the OFF position.
ENGINE COOLANT
The engine is equipped with a pressurized cooling system. Under
normal operating conditions, the coolant in theengine andradiator
isunder high pressureandis veryhot. Contact withhot coolantcan
cause severe burns. Do not remove the cap from a hot radiator; if
the cap must be removed, do sovery slowly in order to releasethe
pressure without spray.
REFRIGERANTS
The refrigerant contained in the refrigeration system of your unit
can cause frostbite, severe burns, or blindness when in direct
contact with the skin or eyes. For this reason, and because of
legislation regarding the handling of refrigerants during system
service, we recommend that, whenever your unit requires service
of the refrigeration system, you contact your nearest Carrier
Transicold authorized repair facility for service.
BATTERY
This unit is equipped with a lead-acid type battery. The battery
normally vents small amounts of flammable hydrogen gas. Do not
smoke when checking the battery. A battery explosion can cause
serious physical harm and/or blindness.

UNIT IDENTIFICATION
Each unit is identified by a decal attached to the frame of the unit.
This decal is on the roadside vertical frame post behind the
roadside side door. This decal identifies the complete model
number of the unit, the serial number, the refrigerant charge and
quantity, and the date the unit was placed in service.
If a problem occurs, please refer to the information on this decal,
and make a note of the model andserial number before calling for
assistance. This information will be needed when you contact a
technician orCarrier TransicoldService Engineer sothat they may
properly assist you.

62--10601
The microprocessor controller will run a self test. All of the mode
lights will light, all of the segments on the display will be turned on.
The display willthen show the setpoint temperature onthe left and
the box temperature of the trailer on the right. The last character
(after the degree symbol) shows the temperature units as F
(Fahrenheit) or C (Celsius).
If the unit is in Auto Start/Stop mode or Continuous Run/Auto
Operation mode, the glow plugs will energize, the buzzer will
sound, and the diesel engine will start.
If the unit is set for Continuous Run/Manual Operation mode, the
unit must be started manually.
WARNING
Under no circumstances should ether or any other
starting aids be used to start engine.
The microprocessor controller monitors box temperature, battery
voltage, and engine coolant temperature. Once the setpoint is
reached the controller will shut off the diesel engine to conserve
fuel. The controller willnot shutoff theengine ifthebatteryvoltage
is not sufficient to restart it.
The controller will restart the engine if any of the following criteria
have been met:
SBox temperature has changed by ¦ 11°F(¦ 6.1°C)for setpoints
in the perishable range and +1 1° F(+6.1°C) for setpoints in the
frozen range DURING minimum off time.
SBox temperature has moved away from setpoint by ¦3.6°F
(2.0°C) AFTER minimum off time for setpoints in the perishable
range or +3.6°F(2.0°C) for setpoints in the frozen range.
SThe battery voltage drops below 11 Vdc (12.2 Vdc for units with
EEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).
SThe engine coolant temperature drops below 34°F(1°C).

The PRETRIP mode is for checking unit operation and evaluating
operation of all modes. The unit will cycle thru all modes of
operation at30 secondintervals. WhenPretripis complete,Pretrip
mode is terminated and the unit returns to normal operation.
The final PRETRIP mode is Defrost. When Defrost ends,
PRETRIP will be complete.
This is not a self-diagnosing pretrip test. Nospecific pretrip alarms
will be generated. Pretrip must be monitored by the user to verify
that the unit operates through all cycles.
See Page 28 for more information on Pretrip.

Setpoints of -22°Fto+89°F (-30°Cto+32°C) may be entered via
the keypad. The controller always retains thelast entered setpoint
in memory. If no setpoint is in memory (i.e. on initial startup), the
controller will lock out the run relay and flash “SP” on the left hand
display until a valid setpoint is entered. The setpoint may be
changed up or down in 1° increments by pressing and releasing
either the UP ARROW or DOWN ARROW key.
Youcan notchangesetpoint when unit isin Pretripor whenviewing
Unit Data or Functional Parameters.
Pressing the ENTER key will cause the new displayed setpoint
value tobecome active. If thedisplay is flashing and the newvalue
is not entered, after 5 seconds of no keyboard activity, the display
will flash for 5 seconds and then revert back to the last setpoint.
All other keys are active at this time and may be pushed while the
display is flashing.
