8.2.5 Surveillance timeout
The firmware of the devices allows you to define a delay time before the
automatic monitoring of the output currents. This is known as the surveillance
timeout.
You can define the surveillance timeout for every individual output channel.
The delay time begins after the output channel has been activated (after a
rising edge) or deactivated (after a falling edge). After the surveillance timeout
has elapsed, the monitoring of the output begins and the diagnosis will report
error states.
The value of the surveillance timeout is 0 to 255ms. The default value is 80ms.
While an output channel is in static state (permanently switched on or off),
the respective value is 100ms.
