9.2.7 Start Override
The start override ensures that the limit value settings "On below limit value" or
"Off below limit value" do not activate the limit value contact even if the value has fallen
below the limit value. This function allows a machine or system start without an alarm
message being output.
When the anti-pumping device is active, the first edge at input ensures the start of the
function. A reactivation is made possible by briefly interrupting the power supply.
