KROHNE OPTISWITCH 4000C Transistor EN - Manual (Page 21)

7.3 Exchange 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 another 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.
To exchange the electronics module, proceed as follows:
1 Separate OPTISWITCH 4000 C from operating voltage
2 Loosen screw (1) of the valve plug (2) with a wrench
(loosen M12x1 plug connection by turning the compression
nut)
3 Remove valve plug (2) or M12x1 acc. 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 oscillator (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
13 Tighten the screw (1) with a wrench (fasten M12x1 plug
connection by screwing the compression nut)
OPTISWITCH 4000 C is again ready for operation.
