1.4.1 Connection of Photocells and Safety Devices
Before connecting the photocells (or other devices), it is
advisable to select the type of operation according to the
movement area they have to protect (see Fig.C):
Opening Safety Devices:
They operate only during the gate opening movement and,
therefore, are suitable for protecting the area between the
opening leaves and xed obstacles (walls, etc) against the
risk of impact and crushing.
Opening/Closing Safety Devices
Closing Safety Devices
Opening Safety
Devices
Connection of ONE Pair of Closing Photocells
and ONE Pair of Opening/Closing Photocells
(Recommended Layout)
Closing Safety Devices:
They operate only during the gate closing movement and,
therefore, they are suitable for protecting the closing area
against the risk of impact.
Opening/Closing Safety Devices:
They operate during the gate opening and closing move-
ments and, therefore, they are suitable for the opening and
closing areas against the risk of impact.
FAAC recommends use of the lay-out in Fig. D (in the
event of xed obstacles at opening) or in Fig. E (no xed
obstacles).
N.B. If two or more devices have the same function (opening or
closing), they should be connected to each other in series (see
Fig. L).
Connection of ONE Closing Safety Device and
ONE Opening Safety Device
Connection of ONE Pair of Closing Photocells,
ONE Pair of Opening Photocells and
ONE Pair of Opening/Closing Photocells
(Recommended Layout)
Connection of NO Safety Devices
NOTE: All safety devices must be connected using
NORMALLY CLOSED outputs.
