With the E24 control unit, you can use both traditional
photocells (N.C. contact with relay) and/or photocells with
BuS-2EASY (open collector contact). The positioning of the
photocells and their operation is schematised in Fig. 5.
6.1 TRADITIONAL PHOTOCELLS
Before you connect the photocells we advise you to select
the type of operation according to the movement zone they
have to protect:
Closing safety devices:
they are tripped only during the
automated system closing movement, and, therefore,
are suitable for protecting the closure zone against the
risk of impact.
Opening safety devices:
they are tripped only during the
automated system opening movement, and, therefore,
are suitable for protecting the opening zone against the
risk of impact.
Opening /closing safety devices:
they are tripped during the
automated system opening and closing movement, and,
therefore, are suitable for protecting the entire movement
zone against the risk of impact.
