Please note
In the case of field bus protocols with which, due to the
limiting of the address range, the settings "32 outputs"
(Midi/Maxi) or "24 outputs" (CPA) together with the CPX
fittings would lead to an error, the DIL switches have been
set at the factory according to the actual number of valve
solenoid coils.
Please note
DIL switch settings which are not represented are not
permitted.
Fitting the cover
1. Check the seal and the surface opposite for damage or
dirt. If necessary, the seal must be replaced (only with
CPX-GP-03-4.0) or the dirt must be removed.
2. Place the cover carefully into position so that the seal is
not damaged.
With CPX-GP-CPA-...: Tighten the screws only by hand.
Place the screws so that the self-cutting threads can be
used.

a TORX screwdriver size T10. Observe the tightening
torques specified in the table below.
