3. Set the DIL switch elements in accordance with the follow-
ing table. Use a suitable tool, e.g. a small screwdriver, for
setting the DIL switches.
The DIL switch contains 8 switch elements. The switches are
numbered from 1...8. The positions OPEN (CPA) or ON (Midi/
Maxi) are marked.
Rules for setting
– If the number of valve solenoid coils fitted is less than the
number of output addresses set with the DIL switch, the
superfluous addresses will be reserved for later exten-
sions (if the maximum number of valves is fitted, output
addresses will then remain unused).
– Modifications to the configuration will not become effec-
tive until the operating voltage is switched on again.
– 8 further output addresses per switch element will be
assigned for valves in the address range.
– The setting of the highest-value DIL switch in the ON
(closed) position is decisive for the assigned address
range.
