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, all electronics modules of series WE60 can be inter-
changed.Ifyouwanttouseanelectronicsmodulewithadier-
ent 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voltage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
4)

6. Pull out 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.
