1)
The fixed control function setting "DNO" should be used for valves with control function 8 (double acting with opening spring). When using the "Auto DNO" setting,
a deviating control function may be incorrectly detected during an automatic initialisation and the initialisation cannot be completed. The "Wrong Function" error
message appears.
2)
Fixed control functions (NC, NO, DA, Boost NC and Boost NO) must match in terms of the actuator's control function. An incorrect assignment may lead to faults and/
or inverted action, and should therefore only be used if the correct control function is known. In case of doubt, give preference to an "auto" detection.
3)
On versions with 300 l/min flow capability (booster), double the number of pilot valves is fitted and connected in parallel. If, in these versions, a control function is set
for simple pilot valves, this leads to a reduction in the flow capability.
4)
A manual initialisation should only ever be carried out if you have not achieved satisfactory control characteristics with the automatic initialisation or this was aborted
due to an error message.
