3.7 - Photocells
The Bluebus system enables the control unit to recognise the photocells in the
system by control routing the relative electric jumpers (see Table 2) and also
enables assignment of the correct value for the "obstacle detection" function.
The routing operation must be carried out on both TX and RX by placing the
electric jumpers in the same way on both and and checking that there are no
other pairs of photocells with the same address. The photocells may be installed
as shown in g. 15.
Important – After installing or removing the photocells, the device learning phase
must be performed, as described in paragraph 3.12.
Notes
- 2 photocells with control function “opens FA1” and “opens FA2” can be
connected to the Bluebus input (it is necessary to cut the A electric jumper at
the rear of TX and RX cards). In this way, when these photocells intervene, the
control unit commands an opening manoeuvre. For further information, refer to
the instruction manual for the photocells.
- It is not possible to have more addresses of the same type on the same
system.
TABLE 2 - PHOTOCELL ADDRESSES
Photocell Jumpers
PHOTO Photocell h = 50 activated when
closing (activated when closing with
inversion on “open”)
PHOTO II Photocell h = 100 activated when
closing (activated when closing with
inversion on “open”)
PHOTO 1 Photocell h = 50 activated when
opening/closing (on “open” the
manoeuvre stops temporarily - on
“close” the manoeuvre inverts on
“open”)
PHOTO 1 II Photocell h = 100 activated, the
manoeuvre inverts on “open”) opening/
closing (on “open” the manoeuvre
stops temporarily - on “close” the
manoeuvre inverts on “open”)
PHOTO 2 Photocell activated on opening
(activated on opening with inversion on
“close”)
