Repair
A repair may only be carried out by the manufacturer.
If the device must be sent back for repair, the following informations must be enclosed:
An exact description of the application.
The chemical and physical characteristics of the product.
A short description of the occurred error.
Before returning the device for repair, the following measures must be proceeded:
All stick product residues must be removed. This is especially important, if the product is unhealthily,
e.g. caustic, toxic, carcinogenic, radioactive etc.
A returning must be refrained, if it is not possible by 100% to remove the unhealthily product
completely, because e.g. it is penetrate into cracks or is diffused through plastic.
Electrical connection
The electrical connection of the device must be carried out according to the respective country specific
standards. Incorrect installation or adjustment could cause applicationally conditioned risks.
Use only suitable cables with max. 25
per wire, that fulfills the requirements e.g. regarding temperature,
resistance or laying at the place of installation.
The cable gland is suitable for cable diameters from 3,5 to 8 mm. After installation of the cable the cable gland
must be fix screwed to ensure the tightness of the connection housing.
Use only shielded signal and measurement wires and install these wires separated from power leading wires.
At strong electromagnetic irradiation use principally a cable with shield. Connect the cable shield only at one
side to earth.
A suitable evaluation device must by connected by the connection cable with the electrode rods inside the
connection housing.
The connection of the cable to the electrode rods is made by terminals for wire cross-cuts up to 2,5 mm
2
or by
screw connections inside the connection housing. For the connection use isolated thimbles.
At electrode probes an additional module (diode module LBM) for the wire supervision can be installed inside
the housing. This must always be connected between the shortest rod and the longest rod.
A connection polarity is not relevant. When using evaluation devices resp. transmitter, that does not support a
wire supervision, this module may not be installed.
For inauguration it is suggested to switch off all connected control devices to avoid unintended control actions.
Two-position-control
For a two-position-control, an electrode probe with three
rods must be used, where the longest rod represents the
reference electrode.
The evaluation device with a function for two-position-control keeps the
filling material level between the upper and the lower limit level.
Four-level-detection
For a four-level-detection an electrode probe with five rods must be
used, where the longest rod represents the reference electrode.
For the evaluation two two-channel-evaluation-devices are used,
whose both reference connection must be connected with the longest
electrode.
