8 Operation
The switch may only be put into service and operated by authorized persons. Do not use any hard
objects for making entries. A self-test is performed on first commissioning.

hard objects.
IMPORTANT
When power supply is switched on the operational status of the switch is indicated by a green
LED. The switching function is not optically indicated.
9 Programming
IMPORTANT
The pressure switch is programmed by means of the membrane key s (T1) and (T2).
