Whenever the unit starts in Start-Stop, it will run until:
• The selected minimum run time has expired
• The compartment temperature is at setpoint
• The battery is fully charged (as indicated in the MessageCenter by “OK”
after the voltage value) AND the charging amps are less than the
Configuration setting.
NOTE
In Electric Operation, if battery condition is the only reason the unit
needs to operate, the compressor will stop but the battery charger will
remain energized.
• And, when in Engine Operation, the engine coolant temperature rises
above 122°F (50°C).
A restart will be initiated when one of the following conditions occurs:
• During the Minimum Off Time, compartment temperature has moved away
from setpoint by 3.6° to 18°F (2° to 10°C) depending on the Functional
Parameter settings
• The Minimum Off Time has expired and the compartment temperature has
moved away from setpoint by more than the Restart Functional Parameter
setting 0.5° to 18°F (2° to 10°C)
• Maximum Off Time has expired. The Maximum off time setting ensures
that the entire load stays within safe temperature range. The unit will start
after a pre-selected maximum off time-regardless of any change in
compartment temperature
• Battery voltage falls below the configured setting (12.0 to 12.8 V). In
Electric Operation, if battery condition is the only reason the unit needs to
restart, only the battery charger will be energized
• When in Engine Operation, coolant temperature drops below the
configured setting 10° to 32°F (-12.2° to 0°C)
If the engine fails to start after three start attempts, alarm 00031 - “FAILED TO
START-AUTO MODE” will be activated. While running, if the unit shuts down
on a safety or fails to run for the minimum run time, three consecutive times,
alarm 00030 - “FAILED TO RUN MINIMUM TIME” will be activated. The
shutdown counter is cleared when the engine has run for 15 minutes or when
the unit cycles off normally. In Electric Operation, the unit will stop for a
minimum of five minutes instead of 15 minutes.
In Continuous Operation the unit will not shut down, except in response to a
shut down alarm. Continuous Operation provides constant evaporator air flow
and temperature control for the product.
