7.3.9 Gas / oil pressure switch-max (Pmax) / or POC contact, start
release oil X5–02
Input for connection of a pressure switch-max for gas or oil: The sensor must have an
NC contact, which means that the contact opens when the adjusted maximum pressure
is exceeded. If the plant does not require a pressure switch-max, a wire link must be
fitted between pin 2 and 3.
Caution!
The OEM must check to see whether the burner can be operated without
pressure switch-max. This may necessitate a special approval, depending on
the type of application.
