CAUtIon
Please observe the following to ensure smooth
operation:
– Route valve and closed position indicator cables
separately through M20 cable glands or use two
separate plugs. Otherwise, there is a risk of
interference between valve voltage and closed
position indicator voltage.
➔ To make wiring easier, the connection terminal for
the closed position indicator can be removed.
➔ When installing two plugs on a VAN with closed
position indicator: label the sockets and plugs to
avoid confusion.
➔ Ensure that the connection terminal for the closed
position indicator has been reconnected.
