Safety Instructions
This instrument is built and tested according to the current EU-direc-
tives and packed in technically safe condition. In order to maintain this
condition and to ensure safe operation, the user must follow the hints
and warnings given in this instruction.

All electrical wiring must conform to local standards. In order to prevent
stray electrical radiation, we recommend twisted and shielded input
cables, as also to keep power supply cables separated from the input
cables. The connection must be made according to the connecting
diagrams.
Before switching on the power supply take care that other equipment
is not affected. Ensure that the supply voltage and the conditions in the
environment comply with the specification of the device.
Before switching off the supply voltage check the possible effects on

Mechanical Installation
Welding part
Please refer to “Accessories” data sheet. The welding part has an
engraved mark or hole. When the product has been mounted and
correctly tightened the gland or M12 plug will align with this mark.
Make sure that the gland/plug is pointing downwards to prevent fluids
from penetrating into the instrument.
Cautions
Use only the authorised special designed accessories.
The product warranty is void when installed with other adapters.
The sensor can be shortened.
Coated rods: Remove approx. 10 mm of the coating from the rod tip to
ensure a proper contact to the media.
Do not use teflon, paper or other gaskets.
The process connection must have electrical contact with the tank.
if not, a separate grounding cable must be installed.
If the tank is non-conductive an additional ground electrode must be
installed. This should have electrical connection to the LSK process
connection.
Make sure that the rod can not touch the tank wall even with the highest movement of the media.
When installed <100 mm from the tank wall the rod must be parallel
with the tank wall. For larger distances non-parallelity can be allowed.
After carefully insertion of the sensor into the welding part tighten the
union with a torque of:
LSKx2x: 10...20 Nm.
LSKx5x: 20...30 Nm.
After Installation and Configuration
Check the leak tightness of the sleeve.
Check the tightness of glands or M12 plugs.
Check the tightness of the cover.
Check that the rod is not touching the tank wall.

WARNING:
Do not connect the LSK to a high DC potential, which could damage
the sensor. The most suitable evaluation module is a type with a
sensing frequency > 200 Hz and input voltage < 5Vrms.
