Inside a CK actuator

The FF CP card is suitable for fitting into CK
wiring diagrams. The connections and fitting in a CK
information effectively relates to both actuator types. The FF CP card is normally located in the first
option board slot inside the electrical housing, using Main PCB connection SK2.
The Interface card must be correctly profiled and loaded with the appropriate connectors to match the
actuator. The illustration below shows the location of the cards in the Centronik unit.

Within the actuator the remote inputs are always present (they are conditioned by the FF CP card) and
there is an option to include Digital Outputs from relay contacts. If the FF CP card is required to
operate the 4 digital outputs that can be controlled from the card, then the Extra Relay Indication card
associated with these outputs must be fitted into the actuator. The following table describes the wiring
harnesses and their function in the Centork actuator.
