Switch senses through the wall AND no hole is needed. Four Level Switches can be connected to
one Ultrasound Controller.

Connecting the Level Switch
The cable from the Level Switch should
connect directly to the Ultrasound Controller.
(Yellow and green cable are not used.) The
cable screen must always be connected to
Ultrasound Controller (screened cable must
always be used). Any unscreened part of the
cable should be no longer than 30mm. To
minimize the risk of electric interference it is
important that sources of interference like
frequency inverters should use screened
cables between inverter and motor.
In an ex-installation, shielding aluminum
plates must be placed outside each group of
zener barriers belonging to each Ultrasound
Controller, order number: Ex-barriershield,
see Level Switch Ex manual.
