4.5 Connect sensors and control
A connection overview of the printed boards is given at the end of this chapter.
4.5.1 Sensors without ATEX requirement
Pressure sensor
If a pressure sensor is to be used to detect the filling level it
has to be connected as follows.
With the help of a spiral cable puller, feed the pressure
hose through the conduit pipe; to do so, fix the end of the
hose with end cap on the spiral cable puller.
Cut off the end of the pressure hose with end cap to fit
precisely.
Push the pressure hose onto the connection nipple of the
pressure pipe connection.
Tighten the clamping nut.
Lay pressure hose continuously rising.
In case of lengths of more than 10 m or reverse gradient
of the pressure hose, use the compressor set for air bub-
bling (art. no. 28048).
4.5.1.1 Connecting float switch without ATEX
Mono float switch
If float switches are to be used to determine the fill level,
check whether the system is a Mono or a Duo system and
connect accordingly.
Connect the ends of the float switch cables to the terminals
(see "Fig. 1: Float switches Mono").
Several float switches (Duo)
Connect the ends of the float switch cables to the terminals
(see "Fig. 2: Float switches Duo").
