SLEEP MODE ON (Continued)
If Sleep Mode is selected, when the unit is not running
(Start-Stop Off Cycle), any remaining Minimum Off
Time will be ignored, and the engine will start. It will run
for 4 minutes (minimum), until the Engine Coolant
Temperature is above 122
°
F (50
°
C), and the battery is
fully charged (O.K. appears in the Data List voltage line,
and charging amps are less than amps set in the
Configuration List). While the unit is running in Sleep
Mode, “SLEEP WARNING: NO TEMP CONTROL” will
flash in the MessageCenter, and the Main Display
(setpoint and box temperature) will be turned off. This is
because box temperature does not have to be at
setpoint to allow the unit to cycle off (go to sleep).
If the unit is already running when Sleep Mode is
selected, it will continue to run until the conditions
described above are met, then shut off (go to sleep).
There is
NO TEMPERATURE CONTROL
in Sleep
Mode and it should never be used for hauling perishable
or frozen products.
While the unit is cycled off in Sleep Mode,
“SLEEP MODE, OFF/ON TO WAKE” will be displayed
in the MessageCenter. The display backlight will turn off
after 5 minutes. Sleep Mode may be exited by either
turning the Start / Run -- OFF switch to the OFF position,
then back to the ON position, or by accessing the
Functional Parameter list, and selecting
“SLEEP MODE: OFF”.
While in Sleep Mode, Unit Data and Alarm Lists may be
viewed, and Functional Parameters may be viewed and
changed as necessary. However,
Start--Stop /Continuous Run selections, and setpoint
can not be changed. Manual Defrost and Pretrip can be
initiated.
The unit will restart when engine coolant temperature
drops below 34
°
F (1
°
C) or if the battery voltage drops
below the battery restart value selected in the
configurations (See 5.2.1)
Sleep Mode is used generally in cold ambients when the
trailer may be parked or not used and the unit is OFF for
an extended period of time (1 day to several weeks) with
no product inside the refrigerated compartment. Many
times units are very difficult to start due to a discharged
battery, thickened engine oil, etc. after that time in cold
ambients.
In Sleep Mode in Engine/Road Operation the unit will
“Wake Up” periodically and run to keep the battery
charged and the engine warm.
In Sleep Mode in Electric Standby Operation the
compressor will be off and the the battery charger will
keep the battery charged.
NOTE (FOR ENGINE OPERATION ONLY)
In the event that the Engine Coolant Tempera-
ture sensor fails, Sleep Mode will operate as fol-
lows:
In ambients above +32
°
F (0
°
C), the unit will run
as above, and will monitor battery voltage and
charging amps only (according to the configura-
tion setting).
In ambients below +32
°
F (0
°
C), the unit will run
for 20 minutes minimum run time, then restart
every 60 minutes (maximum off time). Battery
voltage and amperage will be monitored nor-
mally.
NOTE
Units equipped with IntelliSet option can select
sleep mode by choosing IntelliSleep. (See Sec-
tion 3.20.1).
