7.2.5 Relay Outputs
NOTE The relay output connection depends on the
application and the connected actuators.
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:
Current up to Capacitor C Resistor R
60 mA 10 nF 260 V 390 Ω 2 W
70 mA 47 nF 260 V 22 Ω 2 W
150 mA 100 nF 260 V 47 Ω 2 W
1.0 A 220 nF 260 V 47 Ω 2 W
❏ With DC voltage: connect freewheeling diode parallel to relay or contactor.
CAUTION Provide relay outputs on site with an appropriate
backup fuse!
NOTE These connections depend on the type of actuator
used, and should only be understood as guidelines.

7.2.6 Screwing the Sensor into the Dosing Head
● Screw in the sensor from the lower side into the hole of the dosing head
flange (M14 x 1.5).
❏ Now the diaphragm breakage indication is ready for start-up.
