Disconnect all electrical connections from the printed circuit board
(plug and / or screw connections).
Loosen the four screws (Torx 10) with which the cover plate is secured.
Remove the cover plate.
Remove all circuit boards (no screw fittings).
Insert the new circuit boards.
Replace the cover plate.
Screw down the cover plate (Torx 10; tightening torque 0.7 Nm).
Reconnect the electrical connections according to the markings made
earlier.
Refit the cover.
ATTENTION!
Ensure the correct fit of the circuit board an the screw

Replacing the valve group
The valve group consists of a connection plate with 1, 2 or 3 flanged
valves of the type 6510 and the O-rings for the fluidic flange to the
housing.
NOTE
Proceed as follows:
Remove the cover.
Before disconnecting from the circuit board, mark the electrical
connections so that it will be possible to reconnect them without

Fit the new valve group complete with its O-rings.
Screw down the valve group (Torx 20; tightening torque 1.5 Nm).
Reconnect the electrical connections according to the markings made earlier.
Refit the cover, ensuring that the O-rings are correctly seated.
ATTENTION!
Ensure the correct fit of the printed circuit boards into
the housing projections!
For 24 V DC without communication, ASI and
DeviceNet, only a change of the whole valve group
is permitted.
