8.3. configuring the selectors
Only move the selectors when the power supply is off.
→
Before wiring the device, configure the selectors on the electronic board: see chap. "8.3.1" to "8.3.3".
8.3.1. floW sensor selector
The FLOW SENSOR selector makes it possible to configure the type of flow sensor: coil or Hall.
For the version with male fixed connector, the selector is factory-set depending on the output signal of the flow
sensor mounted on the device.

8.3.2. source/sinK selector
The Source/Sink selector makes it possible to set the 4-20 mA current output of the versions with relays, in sourcing or in
sinking mode. Set the selector depending on the type of wiring.
