8. ACCESSORIES
8.1 RELAY PHOTOCELLS
!
Photocells are additional type D detection devices
(according to EN 12453) that reduce the likelihood of
contact with the moving leaf. The photocells are not
safety devices according to standard EN 12978. De-
tection devices used as safety accessories (e.g. sensi-
tive edges) to protect against a hazard, must comply
with standard EN 12978.
i
Use photocells with a NC relay contact. If multiple
photocells are used, the contacts must be connected
in series.
Position and connect the photocells according to their
required use:
FSW CL
Photocell active during closing
FSW OP
Photocell active during opening
FSW OP/CL
Photocell always active
i
The action carried out when the photocells are trig-
gered depends on the operating logic selected.

■ Failsafe
Failsafe is a functional test that is carried out before a
movement. It consists of momentarily interrupting the
power supply to the devices and checking the change
in status of the input.
If the test fails, the board generates an error and pre-
vents the automation from moving.
To enable the Failsafe test: connect the negative of
the photocell transmitters to an output (OUT1/OUT2)
configured as a Failsafe function (
o1 or o2=01) instead
of to the accessories power supply negative (-).
