LOW POWER (SLEEP) MODE
A low power mode is available to allow the module to minimize power consumption during times
when the panel is on, but the engine is not running. This may occur simply because an operator has
left the key on without starting the engine or the engine had been running, but was shut down due to
a fault condition such as high engine temperature, low oil pressure, low fuel level, over speed or any
other monitored switch input such as a low coolant level switch.
To minimize current draw, the module goes into a sleep mode after a programmable time period
(two-minute default) after being powered on without the engine starting or after a protection
shutdown occurs. While in sleep mode, the display goes blank and the red lamp blinks once every ten
seconds. The engine
’s
ECU circuit is de-energized as to not allow a continuous power drain.
The module will wake up and resume normal operation if any key is pressed or the power is cycled off
and then back on. If any of the keys are pressed, the display will resume and show the last message
displayed prior to entering the low power mode. This would include the shutdown message if the
panel had performed a safety shutdown thus enabling the operator to see what condition occurred.
However, if the operator turned the key off and then back on, the display would not indicate the safety
shutdown message, but the alarm would be recorded in the Alarm Log menu section for reference.
