Function And Features - IFM Electronic LI5045 Bedienungsanleitung

1. Function and features

Applications:
The unit was specially designed to meet the requirements of machine
tool building. It is specially suitable for monitoring coolant emulsions
as well as other hydrous media.
The unit is virtually immune to build-up of almost any kind on the
probe (e.g. particles of metal, foam).
The sensor is not suitable for oils, granulates and bulk materials, acids
and alkalis. It is not suitable for food and electroplating applications.
In case of doubt ensure the correct function by performing a test in
your application.
Description of the function
The sensor detects the level of media in tanks.
• The unit detects by direct contact with the medium whether the
requested level is reached and indicates this by a switched signal
(N.O. or N.C., programmmable by wiring; → page 11).

• The level is determined by the installation length (→ page 10,
Installation).
• The unit is preset at the factory and is immediately ready for ope-
ration if used correctly. On delivery the programming button is elec-
tronically locked. Programming or adjustment are not necessary!
• Installation: vertical from the top.
The unit operates with radial detection characteristics. Therefore
media below the active zone are not detected in the case of verti-
cal installation. Media are only detected when the active zone is
covered.
