Proof of closure switch
▷
VAS open: contacts
1
and
closed,
VAS closed: contacts
1
and
closed.
▷
Indicator of proof of closure switch: red = VAS
closed, white = VAS open.
▷
Double solenoid valve: if a plug with socket is
fitted, only one proof of closure switch can be
connected.
CAUTION
Please observe the following to ensure smooth
operation:
– The proof of closure switch is not suitable for
frequent cycling operation.
– Route valve and proof of closure switch cables
separately through M20 cable glands or use
two separate plugs. Otherwise, there is a risk
of interference between valve voltage and proof
of closure switch voltage.
▷
To make wiring easier, the connection terminal
for the proof of closure switch can be removed.
