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 Exchange of the electronics
To exchange the electronics in case of failure, it is not necessary to
dismount the instrument.
Dismounting the electronics module can destroy the housing seal.
Therefore only open the instrument if you want to insert a new
electronics module. The housing seal is supplied with the electronics
module.
You require an electronics module type SWE50T or SWE50C. If you
want to use an electronics module with a different signal output (e.g.
contactless electronic switch SWE50C), you can download the
suitable operating instructions manual from our homepage under
Downloads. Take note of the specifications in the respective operating
instructions manual.
Proceed as follows to exchange the electronics module:
1 Separate VEGASWING 51 from operating voltage
2 Loosen screw (1) of the valve plug (2) with a wrench (loosen
M
12 x 1 plug connection by turning the compression nut)
3 Remove valve plug (2) or M12 x 1 according to drawing
4 Remove lateral fixing screw (7) with a crosstip screwdriver
5 Pull electronics module (4) carefully out of the housing (8)
6 Remove the plug of the connection cable (6) from the socket on
the electronics module (4)
7 Set the 16-step rotating switch (5) of the new replacement
electronics module (4) to the value of the defective electronics
module
8 Insert the connection cable (6) in the socket of the new electronics
module (4)
9 Insert electronics module (4) into the housing (8). Make sure that
the lateral thread on the electronics module is above the hole on
the housing (8)
10 Push the electronics module (4) flush into the housing (8)
11 Screw in the lateral fixing screw (7) with a crosstip screwdriver
12 Plug the valve plug (2) to the instrument, make sure that the profile
seal (3) is placed correctly
