Release Engine Monitoring screen
In the default setting of the easYgen the engine start/stop is executed by the easYgen
directly. So the engine monitoring is released, if the control energizes the solenoid valve
(Start/Gas 11657) and the firing speed is reached. In the moment the easYgen removes
the solenoid valve the monitoring is disabled. This avoids wrong alarms during the engine
stopping procedure.
In cases the start/stop of the drive is executed from outside, the command variable 03.28
Start/Gas (11657) is replaced by a command from outside i.e. any discrete input (09.XX).
With starting the drive the operator gives the command for monitoring. With stopping the
drive the command has to be removed to avoid wrong alarms during the engine stopping
procedure.
The delayed engine monitoring can be seen with the upcoming “Eye” symbol in the
single line diagram.

To configure the MPU input, the number of teeth on the flywheel detected by the
magnetic pick up (MPU) or the number of pickup pulses per revolution of the engine must
be configured.
