Page 5: Basic Description
(PEEK) extended electrode part, for sensing various liquids, slurries and pastes, also suitable for acids or bases. The durable stainless steel RFLS-24_-11-_-_-CM connector version (without LED indication) is designed for more demanding condi- tions, setting with a programming wire © Dinel, s.r.o. RFLS–24...

** Typical switch point position for oil (factory setting) *** Supplied without outer gasket as standard. 4 . Putting into operation This procedure has the following three steps: • Mechanical installation - chapter 9 • Electrical connection - chapter 5 • Setting - chapter 8 RFLS–24 © Dinel, s.r.o.
Page 7: Electrical Connection
5. Electrical connection RFLS-24 sensors are connected to the evaluation units or binary onputs of PLC by a cable via a standard M12 connector. Sensors with PNP output type can only be loaded with resistive or inductive loads. Capacitive loads and loads with low quiescent resistance (light bulb) can be evaluated by the sensor as a short circuit.

Page 11: Basic Setting With The Presence Of Medium With Magnetic Pen
The sensitivity and switching mode of the RFLS-24 sensor can be set: 1) locally using a magnetic pen (CP version with plastic connector and indication), which is attached to the magnetically sensitive ON or OFF pads on the sensor 2) remotely via a setting wire using the DSU-1222-AP power supply unit (all versions).

Page 14: Quick Setting Without The Presence Of Medium With Dsu-1222-Ap Unit
WITHOUT MEDIUM WITH DSU - 1222 - AP UNIT ( all versions ) The RFLS-24 sensor can be set using a programming wire or a special evaluation unit DSU- 1222-AP. The evaluation and power supply unit DSU-1222-AP is designed to connect one or two RFLS-24 sensors.
Page 15: Mechanical Installation
9 . Mechanical Installation RFLS-24 level sensors can be mounted horizontally or obliquely in the shell of a vessel, tank or pipe by screwing into a weld-on fitting or by fastening with a nut. Basic application recommendations are given below. Fig. 5: Correct orientation of sensor installation in tanks Fig.
Page 16 In the case of sensing aggressive media, it is necessary to check the chemical resistance of the materials from which the sensor is made (see tab. Material design on page 22). The warranty does not cover any chemical damage. RFLS–24 © Dinel, s.r.o.
