red = VAN closed, white = VAN open.
CAUTION
Please observe the following to ensure smooth
operation:
– Route valve and closed position switch cables
separately through M20 cable glands or use
two separate plugs. Otherwise, there is a risk of
interference between valve voltage and closed
position switch voltage.
▷
To make wiring easier, the connection terminal
for the closed position switch can be removed.
