9.1.5 Relay outputs
• Interference suppression is required for inductive loads (also
relays and contactors).
• If this is not possible, protect the relay contacts using a
suppressor circuit as described below.
With AC voltage
With DC voltage
• Connect the free-wheeling diode parallel to the relay or
contactor.

9.1.6 Screwing the sensor into the dosing head
• Screw the sensor from the lower side into the hole of the
dosing head flange (M14 x 1.5).
– Now the diaphragm leakage sensor is ready for start-up.
