Probe with thread
• G ½, G ¾, G 1 or G 1½ (cylindrical): – To be used with the elastomer fibre seal supplied (temperature-resistant up to 300 °C) or
another chemically resistant seal.
! Note! The following applies for probes with a parallel thread and supplied seal:
• 1 - 14 NPT oder 1 - 11½ NPT (conical):– Wrap the thread by a suitable sealing material (e.g. Teflon) (observe conductivity).
Probe with Tri-Clamp, sanitary connection or flange
• The process seal must meet the specifications of the application (resistant to temperature and medium).If the flange is PTFE-clad, this generally suffices as the seal up to the permitted operating pressure.
3.4.1 Mounting toolsYou need the following tool for mounting:• Tool for flange mounting or• A wrench AF 41 or AF 55 for the threaded connection and• A Phillips screwdriver for aligning the cable entry.

3.5 Installation examples
3.5.1 Rod probes
Conductive tanks (metal tanks)
If the process connection of the probe is insulated from the metal tank (e.g. through seal material), the ground connection at the probe housing must be connected to the tank by means of a short cable.
! Note! A fully insulated rod probe may neither be shortened nor extended. If the insulation of the probe rod is damaged, this results in an incorrect measurement result.

! Note! See Operating Instructions, rope shortening kit KA063F/00.
3.5.4 Tensioning weight with tensionThe end of the probe needs to be secured if the probe would otherwise touch the silo wall or another part in the tank. This is what the internal thread in the probe weight is intended for. The bracing can be coductive or insulating to the tank wall.
To avoid a to high tensile load the rope should be loose or guyed with a feather. The maximum tensile load may not exceed 200 Nm.

3.5.5 Align the housingThe housing can be rotated 270° to align the cable entry. For an even better way of preventing moisture penetration, we recommend you route the connecting cable downwards before the cable gland and secure it with a cable tie. This is particularly recommended when mounting outdoors.
Housing (type F16, F15, F17, F13, T13)• Unscrew cover• Loosen Phillips screw at bottom of housing by turning the screw 3 to 4 times• Turn the housing to the desired position (max. 270°, from one stop to the next)• Tighten Phillips screw at bottom of housing.
! Note! For housing type T13 with a separate connection compartment, the Phillips screw for aligning the housing is also located in the electronics compartment.
L00-FMI5xxxx-04-00-00-xx-002
1. Loose clamping screw that the housing can be alined easily.2. Align the housing.3. Tighten clamping screw (< 1 Nm) until the housing can no longer be rotated.4. Additional protection against moisture penetration for electronics compartment.
3.5.6 Sealing the probe housingWhen mounting the probe, connecting the electronic insert and later during operation, it is important that moisture does not penetrate the probe housing. For this reason, the housing cover and the cable entries must always be closed tight.
The O-ring seal on the housing cover is provided with a lubricant when delivered. In this way, the cover can be sealed tight and the aluminium thread does not bite when screwing down. Never use a lubricant on a mineral-oil base! This would destroy the O-ring.

3.6.1 Shortening the Connecting Cable
! Note! The maximum connection length between the probe and the separate housing is 6 m and is shown by the dimension L4. When ordering a Liquicap M with separate housing you must indicate the required connection length.
If the connecting cable must be shortened or be led through a wall, you must disconnect the cable from the process connection. Please proceed as follows:
• Loosen the pressing screw (1) with an open-end wrench (size 22). If necessary, hold the process connection. Please make sure that neither the connecting cable nor the probe is turning with the pressing screw.
• Pull the insert seal (2) out of the cable gland (3).• Loosen the cable gland (3) with an open-end wrench (size 22). If necessary, hold the adapter disk
(6) with an open-end wrench (size 34).• Loosen the adapter disk (6) from the tube (17).• Remove the snap ring with a pair of snap ring pliers.• Clutch the nut (M4) of the blade plug with a pair of pliers and pull this out.
! Note! If you are shortening the connecting cable, we recommend to reuse all strands with ring terminals. After the strands were soldered on again the soldering points must be isolated.
! Note! If the strands are not reused, the ring terminals of the yellow and the red strand must be isolated at the crimp connection e.g. with a heat shrinking sleeve (Danger of short-circuit).
Mounting a wall bracket or pipe bracket
Wall mounting
• Push the wall bracket onto the tube and screw it together.• Mark the distance between the holes on the wall and drill the 2 holes.• Screw the separate housing on the wall.
L00-FMI5xxxx-03-05-xx-xx-010

Cleaning Housing:
When cleaning, make sure that the cleaning agent used does not attack or corrode the housing surface or seals.
Probe:
Depending on the application, build-up (contamination and soiling) can form on the probe rod. Build-up that crystallises out can affect the measurement result. If the medium tends to create a high degree of build-up, regular cleaning is recommended. When hosing down or during mechanical cleaning, it is important to make sure that the insulation of the probe rod is not damaged. If cleaning agents are used make sure the material is resistant to them!
Electromagnetic compatibility (EMC)
• Interference emission to EN 61326, Electrical Equipment Class BInterference immunity to EN 61326, Annex A (Industrial) and NAMUR Recommendation NE 21
• A screened cable generally has to be used for PFM.
