Selecting Sleep Mode
Normal CYCLE-SENTRY mode starts and stops
the unit as required to maintain the desired
compartment temperature, maintain the unit
battery in a charged condition and keep the unit
engine warm in cold ambient conditions. Sleep
mode does not maintain compartment
temperatures – it only keeps the engine warm and
the unit battery charged. This is useful in
extremely cold weather or when the unit is to be
out of service for an extended time.
Sleep mode operates in both Diesel mode and
Electric mode. In Diesel mode the unit will start
and stop as required to maintain engine
temperature and battery charge. In Electric mode
the unit starts and stops as necessary to maintain
battery charge only.
When Sleep mode is entered, the operator can
program an automatic Wake-up Time up to a week
away. Using this feature, the unit will
automatically restart and run normally at the
determined time. If a Wake-up Time is
programmed, the operator can also program an
automatic Pretrip Test when the unit restarts.
