6.2 PHOTOCELLSBUS-2EASY
This board is supplied with a BUS-2EASY circuit enabling easy
connection of a high number of BuS-2EASY safety auxiliary
devices (e.g. up to 6 photocells pairs), appropriately
programmed, using only two cables without polarity.
Before connecting the photocells, we advise you to select the
type of operation (Fig.24) according to the movement zone
they must protect and position – bothonthetransmitterand
receiver - the dip-switches as shown in Tab.:
Closing photocells: 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 photocells:
they are tripped only during the
automated system opening movement, and,
therefore, are suitable for protecting the opening zone
against the risk of impact.
If you have to connect two or more
BUS-2EASY opening photocells, choose
differentaddressesforeachpairused.
Opening/Closingphotocells:
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.

Pulse generators:
used as pulse generators to open the
automated system.
A maximum of 6 pairs of BuS-2EASY photocells can be
connected to the board.
The photocells are split into groups:
