5.4.1. Connection of Photocells and Safety Devices
Before connecting safety devices and photocells, it is advisable
to select the type of operation according to the area they have to
protect (see Fig. 24 for example).
Opening Safety Devices:
Tripped when an obstacle is detected only during gate
opening movement. They cause immediate reversing
and resumption of the opening motion on release (see
programming in Section 5.5.2.)
Closing Safety Devices:
Tripped when an obstacle is detected only during gate
closing movement. They cause reversing, either immediate
or on release (see programming in Section 5.5.2.)
Opening/Closing Safety Devices:
Tripped during the gate opening and closing movements.
They cause stopping and restart motion on release.
"Edge" Safety Devices:
Tripped during the gate opening and closing movements.
They cause immediate reversal of motion and stopping
after two seconds.
Encoder:
Monitors for an obstacle during gate opening and closing
movements. It causes immediate reversal of motion and
stopping after two seconds.
N.B: If two or more safety devices have the same function (ope-
ning, closing, opening and closing, edge), the contacts must
be connected to each other in series (Fig. 25).
N.C. contacts must be used.
N.B: If safety devices are not used, jumper the terminals as
shown in Fig. 26.
The most common photocell and safety device lay-outs are shown
below (from Fig. 27 to Fig. 34).
