1.1 Intended use
Installation
2.1 Preparation
The electromechanical level limit switch is monitoring the filling level of bulk goods in silos, bunkers,
containers, hoppers, weighers, etc..
1.2 Construction control head
(housing with motor and switch)
- Read and follow the safety instructions and the operating instructions before mounting the device!
- Inspect if the delivery is complete.
The delivery volume is different, depending on the options.
2.2 Mounting Thread connection Put the level indicator together with the sealring at
the provided position in the silo or container wall and screw it tightly by means of appropriate tools.

1.3 Function The rotating measuring blade, projecting into the silo or container, is driven by a gearmotor.
If the bulk material is reaching the measuring blade, the rotation will be hindered and it will be stopped.
The return torque turns the pivoted motor from its end position and actuates the signal switch. A second
switch turns the motor off.
If the filling level of the bulk material sinks, the blade becomes freely again and a spring will turn back the
motor into its original end position.
Thereby the motor will be turned on again and the signal switch will be switched back.
