7 Maintenance and fault rectification

VEGASWING 63 • Two-wire 8/16 mA

29232-EN-180704

Error

Cause

Rectification

Control lamp off

Error on the vibrating el-

ement

Check if the vibrating element is damaged or extreme-

ly corroded.

Interference on the elec-

tronics module

Exchanging the electronics module

instrument defective

Exchange the instrument or send it in for repair

Depending on the reason for the fault and the measures taken, the

steps described in chapter "

Set up

" may have to be carried out again.

7.3 Exchanging the electronics

If the electronics module is defective, it can be replaced by the user.
In Ex applications only an electronics module with respective Ex ap-

proval may be used.
You can find all the information you need to carry out an electronics

exchange in the handbook of the new electronics module.
In general, all electronics modules of series SW60 can be inter-

changed. If you want to use an electronics module with a different

signal output, you carry out the complete setup. You find the neces-

sary, suitable operating instruction on our homepage.

Note:

Keep in mind that enamelled instrument versions need special

electronics modules. These electronics modules are called SW60E or

SW60E1.

7.4 How to proceed if a repair is necessary

You can find an instrument return form as well as detailed informa-

tion about the procedure in the download area of our homepage:

www.vega.com.
By doing this you help us carry out the repair quickly and without hav-

ing to call back for needed information.
If a repair is necessary, please proceed as follows:

•

Print and fill out one form per instrument

•

Clean the instrument and pack it damage-proof

•

Attach the completed form and, if need be, also a safety data

sheet outside on the packaging

•

Please contact the agency serving you to get the address for

the return shipment. You can find the agency on our home page
