CPI Oil:
This is used for checking the oil valves fully closed position.
For that purpose, the valve closure contacts of the oil valves are to be connected in
series and then to this input.
The input is active both with gas-fired and oil-fired operation.
Firing on oil:
In the phases 12 to 38 and in the phases 72 to 78, the input is checked for ON (valve
closed) and in phases 54 and 60, the input is checked for OFF (valve open).
In Standby, OFF (valve open) results in start prevention with display message.
The display message can be output with a time delay (can be set with parameter
