Please note
In the case of field bus protocols with which, due to the
limiting of the address range, the setting 32 outputs"
(VTSA/ISO or Midi/Maxi) or 24 outputs" (CPA) together
with the CPX equipment 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 it for damage or
dirt. If necessary, the seal must be replaced (only with
type CPX−GP−03−4.0) or the surfaces must be cleaned.
2. Place the cover carefully into position so that the seal is
not damaged.
With type CPX−GP−CPA−...: Tighten the screws at first only
by hand. Place the screws so that the self−cutting threads
can be used.
3. Tighten the screws in diagonally opposite sequence with
a TORX screwdriver size T10. Observe the tightening
torques listed in the table below.
