3.17 SLEEP MODE
Sleep Mode is generally used in cold ambients when the unit will be off for an extended period of time with no product
inside the refrigerated compartment. Many times units are difficult to start due to a discharged battery, thickened
engine oil, etc. after time in cold ambient.
There is
NO TEMPERATURE CONTROL
in Sleep Mode and it should never be used if the compartment contains
perishable or frozen products.
In Sleep Mode the unit will “Wake Up” periodically and start the engine to keep the battery charged and the engine
warm.
ADDITIONAL SUB MENUS
1. “WAKE UP TIME” may be set to ON or OFF, the default setting is OFF.
a. When “WAKE UP TIME” is set to OFF the unit will remain in Sleep Mode until it is taken out manually (refer
to the preceding “TO EXIT SLEEP MODE” instruction).
b. When “WAKE UP TIME” is set to ON the “SET WAKEUP TIME” menu will become available.
Pressing the = key will allow the user to select the date and time the unit is to automatically wake up. The wake up
time must be at least 1 hour and no more than 8 days from the time the clock is set. The following information can
be entered:
• Month (1 to 12).
• Day (1 to 31).
• Year (2009 to 2099).
• Hour (0 to 23).
• Minute (0 to 59).
NOTE
The system uses a 24 hour clock. Hours 00 to 11 are AM and hours 12 to 23 are PM.
2. “RUN PRETRIP TEST AT WAKE” may be set to YES or NO, the default setting is NO.
a. When “PRETRIP TEST AT WAKE” is set to NO the unit will wake up at the designated time and control to
setpoint.
b. When “PRETRIP TEST AT WAKE” is set to YES. the unit will wake up at the designated time, automatically
run Pretrip and then control to setpoint. “PRETRIP PASS/FAIL” will remain in the MessageCenter until it is
manually cleared by pressing any key.
If Sleep Mode is selected, when the unit is not running during a 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 tempera-
ture is above 95°F (35°C), the battery is charged (“OK” is displayed in the battery unit data reading) and charging
amps are less than the configured setting.
When the unit is running while in Sleep Mode, “SLEEP WARNING: NO TEMP CONTROL” will flash in the Mes-
sageCenter.
If the unit is already running when Sleep Mode is selected, it will continue to run until the conditions described
above are met.
While the unit is cycled off in Sleep Mode, “SLEEP MODE, OFF/ON TO WAKE” will be displayed in the Mes-
sageCenter. The display backlight will turn off after 5 minutes.
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 the configured restart temperature value or if the
battery voltage drops below the configured battery restart value.
