1 Preliminary note 1.1 Symbols used ► Instructions > Reaction, result […] Designation of keys, buttons or indications → Cross-reference Important note Non-compliance may result in malfunction or interference� Information Supplementary note� 2 Safety instructions • The device described is a subcomponent for integration into a system� - The manufacturer of the system is responsible for the safety of the system�...
• If required, 1 coaxial pipe (for operation of the unit with coaxial probe → 4.2) • Mounting material (if necessary, a launching plate → 4.1). Only use accessories from ifm electronic gmbh! The optimum function is not ensured when using components from other manufacturers�...
4.1 Operation with single probe The single probe is made up of one individual rod� Operation with single probe is suited for the detection of aqueous media, in particular of heavily soiled aqueous media� For the correct function with single probe, the unit needs a large enough metal launching plate�...
Application examples: • Detection of coolant emulsion in a machine tool� • Detection of cleaning liquid in a parts cleaning system� • Monitoring of hydraulic oil in a hydraulic power unit (only for operation with coaxial probe) • Detection of Diesel fuel (only for operation with coaxial probe, in non hazardous areas!)�...
4.4 Special information on DNV-GL approval For use under DNV-GL conditions (if device approval is available), observe the following instructions: • Single probes and coaxial probes up to a length of 500 mm can be operated without support� • For probe lengths from 500 mm to 2000 mm, coaxial probes must be used�...
5.2 Features of the unit 5.2.1 Set-up via IO-Link • The device parameters are set via the IO-Link interface (→ 5.2.5 and → 9)� • All settings can also be carried out before installation of the unit� 5.2.2 Analogue function The unit provides an analogue signal proportional to level�...
In addition communication is possible via a point-to-point connection with a USB adapter cable� For further information about IO-Link view: www�ifm�com/gb/io-link� Device-specific information You will find the IODDs necessary for the configuration of the IO-Link unit and detailed information about process data structure, diagnostic information and parameter addresses at www�ifm�com/gb/io-link�...
6 Installation 6.1 Installation location / environment • Vertical installation from the top is preferred� 6.1.1 Unit with single probe • For safe functioning, the unit requires a launching plate (→ 6.4). • The following minimum distances between the rod and tank walls, objects in the tank (B), tank bottom and other level sensors must be adhered to: 50mm 100mm...

fig. 6-3 fig. 6-4 50mm • Strong foam formation and strongly moving surfaces can lead to malfunctions (see the following fig�)� Recommended remedies: use a coaxial probe, install a still pipe or bypass� Note: minimum diameter d = 100 mm� The upper access to the bypass (A) and the fill openings of the still pipe (B) must be above the maximum level�...
6.1.2 Unit with coaxial probe • No minimum distances to the tank wall and the baffles (B) are required� • Minimum distance to the bottom of the tank: 10 mm� • The vent hole (A) must not be covered by mounting elements or similar�...
Substances such as screw retaining compounds may migrate into the medium� Make sure that they are harmless! When using mechanical means of securing (e�g� tooth lock washer), protruding edges must be avoided� They may cause interference reflection� 6.2.2 Installation of the coaxial pipe This subchapter is only relevant if the unit is to be operated with a coaxial probe�...
6.3 Shortening of the probe 6.3.1 How to shorten the rod and to determine its length L The rod can be shortened to adapt the probe to different tank heights� Ensure that the probe length is never below the minimum permissible probe length of 100 mm (L )! The unit does not support probe lengths below 100 mm�...
► Remove fastening bracket and fig. 6-6 centring piece (A, B)� ► Shorten the coaxial pipe to the requested length: L = L + 9 mm� ► After shortening, at least one hole (C) for insertion of the fixing bracket has to be left� ►...
6.4.1 Installation in closed metal tanks (without flange plate) fig. 6-7 fig. 6-8 fig. 6-9 ► The lower edge of the process connection should be flush with the installation environment (fig� 6-7)� ► Avoid non-flush installation (fig� 6-8)� ► Use seals or washers (D in fig� 6-9) to reach the required height� ►...
Wall thickness [mm] 1���5 5���8 8���11 Bore hole diameter [mm] ► Install the flange plate with the flat surface showing to the tank and fix it with appropriate screws� A seal (B in fig� 6-11) can be inserted between flange plate and tank� Some flange plates are supplied with a seal�...
6.4.4 Installation in plastic tanks 150 mm To enable sufficient transfer of the measured signal, note in case of installation in plastic tanks or metal tanks with plastic lid: ► The plastic lid must be provided with a drill hole with a minimum diameter of 150 mm�...
Only then is the unit ready for operation (→ 9)� 8 Operating and display elements This unit version has no operating and display elements� For parameter setting → 9� For units with display and operating elements → www.ifm.com.
9.1 Parameter setting via PC For parameter setting an IO-Link software is necessary (e�g� "LINERECORDER SENSOR" or "ifm Container")� The USB IO-Link interfaces with the order no� E30396 or E30390 are available for the connection of the sensor via the USB interface of a computer�...
You can find more information about the memory plug in the technical documentation for the article E30398 (available free of charge at www�ifm�com)� 10 Operation After power on, the unit is in the Run mode (= normal operating mode)� It carries out its measurement and evaluation functions and generates output signals according to the set parameters�...
11 Maintenance ► Keep the process connection free of deposits and foreign bodies� ► In case of heavy soiling: clean the process connection and the probe at regular intervals� In case of longer operation separation layers can form in the medium (e�g� oil on water)�...
