6.2 PHOTOCELLS BUS-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 16 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 – both on the transmitter and
receiver - the dip-switches as shown in Tab.1:
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.
If you have to connect two or more BUS-2EASY
closing photocells, choose different addresses
for each pair used.
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
different addresses for each pair used.
Opening /Closing photocells:
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.
If you have to connect two or more BUS-2EASY
closing photocells, choose different codes for
each pair used.
Pulse generators:
used as pulse generators to open the
automated system
.
A maximum of 16 pairs of BUS-2EASY photocells can be
connected to the board.
The photocells are split into groups:
Opening photocells: max 6
Closing photocells: max 7
Opening /Closing photocells: max 2
Photocell used as an OPEN pulse: max 1
6.2.1 ADDRESSING THE BUS-2EASY PHOTOCELLS
Important: the same address must be given
to both transmitter and receiver. (the same
DIP-SWITCH setting)
Make sure that there are not two or more
photocell pairs with the same address. (the
same DIP-SWITCH setting)
If you are not using any BUS-2EASY accessory,
leave free connector BUS-2EASY (J3- fig. 7).
Table 1 shows the programming operations of the dip-switch
inside the transmitter and the BUS 2-EASY photocells receiver.
