3 Product description

3.1 Conguration

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).

Ifyouwanttouseanelectronicsmodulewithadierentsignaloutput,

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. Switchopowersupply

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

Fig. 1: Loosen the holding screws

1 Electronics module

2 Screws (2 pcs.)

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.

Installation procedure

Information:

Make sure that the housing is not rotated during the electronics ex-

change.Otherwisetheplugmaybeinadierentpositionlater.

9. Insert the electronics module carefully. Make sure that the plug is

in the correct position.

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

terminal spring closing

13. Check the hold of the wires in the terminals by lightly pulling on

them

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

encircle the cable.

15. Screw the housing lid back on

Theelectronicsexchangeisnownished.

As a rule, an exchange of electronics must be documented internally

if Ex applications are involved.

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).

Ifyouwanttouseanelectronicsmodulewithacompletelydierent

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.
