3 Product description
3.1 Conguration
The scope of delivery encompasses:
• Electronics module for SITRANS LVL200
• Documentation
– This operating instructions manual
3.2 Principle of operation
The electronics module is suitable for replacement in SITRANS
LVL200 vibrating level switches.
3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
• Storage and transport temperature see chapter "Supplement -
Technical data - Ambient conditions"
• Relative humidity 20 … 85 %

4 Mounting
4.1 Mounting instructions
If the electronics module is defective, it can be replaced by the user.
In Ex applications, only instruments and electronics modules with ap-
propriate Ex approval may be used.
4.2 Mounting preparations
In general, the electronics module can be also exchanged within the
type series against an electronics with another signal output (e.g.
relay against transistor output).
Ifyouwanttouseanelectronicsmodulewithadierentsignaloutput,
you can download the corresponding operating instructions manual
from our homepage under Downloads.
4.3 Installation procedure
To exchange the electronics module, proceed as follows:
1. Switchopowersupply
2. Unscrew the housing lid
3. Lift the opening levers of the terminals with a screwdriver
4. Pull the connection cables out of the terminals
5. Loosen the two screws with a screw driver (Torx size T10 or slot
4)

6. Pull out the old electronics module
7. Compare the new electronics module with the old one. The type
label of the electronics module must correspond to that of the old
electronics module. This applies particularly to instruments used
in hazardous areas.
8. Compare the settings of the two electronics modules. Set the
adjustment elements of the new electronics module to the same
setting of the old one.

10. Screw in the two holding screws and tighten them
11. Insert the wire ends into the open terminals according to the wir-
ing plan
12. Press down the opening levers of the terminals, you will hear the

them
14. Check cable gland on tightness.The seal ring must completely

5 Setup
5.1 Setup
When replacing the electronics module, make sure that all adjustment
elements are set to the settings of the old electronics module. Hence
the sensor is immediately ready for operation.
In general, the electronics module can be also exchanged within the
type series against an electronics with another signal output (e.g.
relay against transistor output).
Ifyouwanttouseanelectronicsmodulewithacompletelydierent
signal output, you have to carry out the complete setup.
The necessary, suitable operating instructions manual can be down-
loaded from our homepage under Downloads.
The adjustment should be carried out according to the description in
the operating instructions manual.
