The IODDs necessary for the configuration of the unit, detailed information about process data structure, diagnostic information, parameter addresses and the necessary information about required IO-Link hardware and software can be found at www�ifm�com� 7 Installation 7.1 Installation location / environment, operation with a single probe •...
• For installation in plastic tanks: (→ 7.5.4) • When operating the unit in small tanks (probe lengths shorter than 200 mm and less than 300 mm distance to the tank wall), mount the unit off-centre (eccentrically) to prevent possible interference from tank resonances� 7.1.1 Minimum distances for installation in closed metal tanks Fig.
For installation in connection pieces: Fig. 7-3 If a pipe is used to make the connection piece (Fig� 7-3), it must not protrude into the tank�The installation causes interfering reflections which are not suppressed by the tank adjustment� 7.1.2 Installation in pipes (bypass pipe, still pipe) The internal pipe diameter (d) must at least have the following value: With adjustment(→...
► For installation according to Fig. 7-6: Reduce parameter [LEnG] by (t) to offset the immersion depth (t) (→ 10.4)� Fig. 7-4 Fig. 7-5 Fig. 7-6 If the probe is fixed at the tank bottom, a low level may already be detected with empty tank�...
7.1.6 Heavy foam build-up and turbulence Heavy foam build-up and turbulence may lead to incorrect measurements� To prevent this: ► Install the sensor in a steady area� Examples how to create a steady area: • Use coaxial probe� Observe the application area of the coaxial probe (→ 5.2)� •...
7.1.7 Notes on tank adjustment Tank adjustment (parameter [tREF]) reduces the effect of interference and ensures a higher excess gain in difficult application conditions� Only carry out a tank adjustment with the unit installed and preferably with empty tank� Two options are available for tank adjustment: [Emty] = Adjustment of the complete probe (recommended)�...
Only if data storage is required in an IO-Link application: The tank adjustment is not saved via IO-Link� After a replacement it must be carried out again� More information about data storage: (→ 15.1) 7.2 Installation location / environment, operation with a coaxial probe ►...
7.3 Installation of the probe The probe is not supplied. It has to be ordered separately (→ 3). 7.3.1 Attaching the probe ► Screw the probe to the unit and tighten� Fig. 7-10 ► Hold the probe at the point of attachment with a second screwdriver to stop it turning (Fig�...
► Slide the seal (A) onto the thread of the sensor� ► Slide the coaxial pipe (B) onto the probe� Carefully centre it and carefully move the probe through the centring piece (C) - for lengths > 1400 mm through both centring pieces - of the coaxial pipe�...
7.4.2 Determine probe length L for single probes ► Precisely measure the probe length L� The reference point is the lower edge of the process connection (Fig� 7-11)� ► Note down L� It is needed for setting the device parameters (→ 10.4)� 7.4.3 Shortening of the coaxial pipe The coaxial pipe and the probe must be of the same length: ►...
7.5 Installation of the unit with single probe Before installing and removing the unit: Make sure that no pressure is applied to the system and that there is no medium in the tank that could leak� Also always take into account the potential dangers related to extreme machine and medium temperatures�...
► Install the flange plate with G¾ process connection (→ Accessories) with the flat surface showing to the tank and fix it with appropriate screws� If necessary, a seal (B in Fig� 7-15) can be inserted between flange plate and tank� Some flange plates are supplied with a seal� If this is not the case, use a suitable seal�...
7.5.4 Installation in plastic tanks 150 mm launching plate (→ Accessories) To enable sufficient transfer of the measured signal, note in case of installation in plastic tanks or metal tanks with plastic lid: ► There must be a hole at least 150 mm in diameter in the plastic lid� ►...
7.6 Installation of the unit with coaxial probe in the tank ► Seal the process connection: - For pipes with G¾ process connection: slide the supplied seal onto the thread of the coaxial pipe� Lightly grease the thread with a suitable paste� - For pipes with ¾"...
