Selecting Sleep Mode
Normal CYCLE-SENTRY mode starts and stops the unit as required to maintain the desired setpoint temperature, maintain the unit battery in a charged condition, and keep the engine warm in cold ambient conditions. Sleep Mode does not consider setpoint or maintain cargo 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 and Electric. In Diesel, the unit will start and stop as required to maintain engine temperature and battery charge. In Electric, 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.
Sleep Mode is turned On and Off using the Mode Menu. From the Standard Display, press the MENU key.
The Language Menu or Alarm Menu will appear. Press the NEXT key as required to show the Mode Menu. When the Mode Menu is shown, press the SELECT key.
Press the Next key as required to display the Sleep Mode prompt. Press the Select key to choose the Sleep Mode menu.
The screen shown ( Start of Sleep Mode Menu) will appear.
The operator can now choose a Sleep Mode Wake-up Time or simply enter Sleep Mode immediately. If NO is pressed, the unit will immediately enter Sleep Mode.
The display will show SLEEP and the unit will start and stop as required to keep the engine warm and/or the battery charged. To exit Sleep Mode, press the EXIT key or turn the unit off and back on. The unit will resume normal operation and control to setpoint.
To enter a Wake-up Time, verify the unit clock is set properly. Press the YES key at the Sleep Mode Menu.
The display will prompt the operator for the DAY the unit is to restart in normal operation. In the example shown ( Confirm Day), Monday has been chosen. Press the YES key to confirm the DAY.
The display will now prompt the operator for the HOUR the unit is to restart in normal operation. In the example shown ( Confirm Hour), 4:00 am has been chosen. Press the YES key to confirm the HOUR (24 hour "military time" is used).
The display will now prompt the operator for the MINUTE the unit is to restart in normal operation. In the example shown ( Confirm Minute), 4:30 am has been chosen. Press the YES key to confirm the MINUTE.
The display will now prompt for a Pretrip Test on Wake-up. Press the YES key to perform a Pretrip Test on Wake-up. If the No key is pressed, the unit will resume normal operation on Wake-up.
The display will show SLEEP and the unit will start and stop as required to keep the engine warm and/or the battery charged.
The unit will restart at the programmed time (in this example 4:30 am) and perform a Pretrip Test (if selected). After the Pretrip Test is complete, the test results will be displayed and the unit will resume normal operation and control to setpoint.
To exit Sleep Mode before the selected Wake-up time, press the EXIT key or turn the unit off and back on. The unit will resume normal operation and control to setpoint.
