4.3 START-STOP OPERATION
Start-Stop is provided to reduce fuel or power con-
sumption. This feature allows full automatic control of
the unit starting and stopping by monitoring refrigerat-
ed compartment temperature, battery charging amps
and (when in Engine Operation) engine coolant tem-
perature. The main function of Start-Stop Operation is
to shut down the refrigeration system near setpoint to
provide an efficient temperature control system and to
initiate a restart sequence after certain conditions are
met. The Start-Stop/Continuous key is pressed to se-
lect between Continuous and Start-Stop Operation.
The corresponding LED will be illuminated.
NOTE
The microprocessor may be locked so that the
unit will always operate in Start-Stop whenever
the setpoint is within a specific range. Refer to
Range Lock (Section 4.6.2) and ProductShield
(Section 4.6.3) for additional information.
4.3.1 Start-Stop Configuration
Microprocessor control of Start-Stop Operation is de-
pendent on both Configuration and Functional Param-
eter settings. The first setting to be considered is the
START/STOP PARAMETERS Configuration. This
setting determines control actions when in the Perish-
able Range or Frozen Range. The available settings
are TOGETHER and SEPARATE.

When TOGETHER is chosen, the same settings
apply to any setpoint.

When SEPARATE is chosen the control action will
be different, depending on whether the setpoint is
in the Perishable range (above -12°C [+10.4°F]) or
in the Frozen range (-12°C [+10.4°F] or below).
If TOGETHER is selected, then the following Func-
tional Parameter values will be available for use:

MINIMUM RUN TIME

MINIMUM OFF TIME

OVERRIDE TEMP

MAXIMUM OFF TIME

FROZEN SHUTDOWN OFFSET
If SEPARATE is selected, then the following Function-
al Parameter values will be available for use:

PERISHABLE MINIMUM RUN TIME

PERISHABLE MINIMUM OFF TIME

PERISHABLE OVERRIDE TEMP

PERISHABLE MAXIMUM OFF TIME

FROZEN MINIMUM RUN TIME

FROZEN MINIMUM OFF TIME

FROZEN OVERRIDE TEMP

FROZEN MAXIMUM OFF TIME

FROZEN SHUTDOWN OFFSET
NOTE
In the event that this Configuration was set to
SEPARATE and the eight Functional Parame-
ters for Perishable and Frozen have been set
and then the Configuration is changed from
SEPARATE to TOGETHER. The values from
the Perishable times will be the ones that will
be used.
4.3.2 Stop Parameters
Whenever the unit starts in Start-Stop Operation, it will
continue to run until
all five of the following criteria
have been satisfied:
1 It has run for the selected Minimum Run Time.
The MINIMUM RUN TIME is selected in the micropro-
cessor Functional Parameters. The purpose of this is
to force the unit to run long enough to completely cir-
culate the air inside the refrigerated compartment, and
to ensure that the product temperature is at setpoint.
This value may be set from 4 to 60 minutes in 1 minute
intervals. The factory default setting is 4 minutes.
2 The engine coolant temperature is above 50°C
(122°F).
Each time the unit is started in Engine Operation it
must continue to run until the coolant temperature
rises to 50°C (122°F) to ensure it has fully warmed up
before shutdown is allowed.
3 The battery is fully charged - Voltage.
A good battery is defined as having 13.4 VDC at 25°C
(77°F). The microprocessor will calculate the equiva-
lent voltage based on the ambient temperature and
shutdown will be allowed when battery voltage is at or
above the calculated value.
