3.8.3 Connecting the level sensor and pressure sensors

• Establish connections for the level sensor as follows.
Alarm sensor
Pressure sensor
Optical probe for backwater flap
Motor for backwater flap
• Route all cables for the electric components and the pressure sensor line safely. Recommendation:
attachment to the cable pipe clamps that can be mounted on the wall of the inspection chamber.
Route the pressure hose (connection e) of the immersion pipe (pressure sensor) in such a way that it always
runs at a rising gradient. This prevents condensation forming which could lead to malfunctions.
