2.7.1 WAKE-UP

NOTE: Either Wake-Up OR Ignition initiates the start-up process. Both must be removed
to allow shutdown to commence.
NOTE: Ignition removal begins the Ignition timer after which the device powers down.
During this delay WakeUp functionality is disabled. Where the application requires WakeUp
functionality, it is recommended to keep Ignition timer to a minimum (minimum setting is 2
seconds).
With ECU power on, a +ve signal on A2 for at least one second initiates the start-up sequence. After
at least one second, the signal must be removed to prevent unintended start-ups following the next
shutdown.
After application of Wake-up (for more than one second), DSEM812 initiates the start -up process,
pausing, awaiting application of Ignition (pin A3). Subsequent application of Ignition allows for faster
start-up of the application given that the device is already 'awake', awaiting application of Ignition.
The Wake-up pin is intended to be driven by an external push button or signal from an external device
such as a vehicle door switch, remote control fob, schedule timer or a controlling PLC.

Wake-Up must be removed before the shutdown
process is initiated. It's recommended to make the
Wake-Up pulse 1.5 seconds to ensure it exceeds the
minimum requirement.
