10.2 PHOTOCELLS
!
Photocells are additional devices that reduce the likelihood of contact with the
moving leaf, but they are not safety devices according to standard EN 12978.
Use photocells with a NC relay contact. If multiple photocells are used, the
contacts must be connected in series. If the photocell inputs are not used,
they must be bridged to terminal TX-FSW:
- no opening photocell, bridge terminals FSW OP and TX-FSW
- no closing photocell, bridge terminals FSW CL and TX-FSW
1. Position and connect the photocells according to their use (
47
).
2. Program the way the automation should operate when the photocells
are triggered:
functions
P h
,
o P
in advanced programming.
3. Enable the FailSafe test (optional):
F S
=
Y
in advanced programming
Opening photocells-FSW OP
. They must be positioned to monitor the
opening stroke. They must be connected as indicated in
48
A
(
one
pair) or
B
(two pairs in series). They are only active during opening.
Operation: function
o P
in advanced programming.
o P
=
Y
reverse, immediate close
o P
=
n o
stop with opening when released
Closing photocells-FSW CL
. They must be positioned to monitor the ac-
cess when it is closing. They must be connected as indicated in
48
A
(
one pair) or
B
(two pairs in series). They are only active during closing.
Operation: function
P h
in advanced programming.
P h
=
Y
stop, reverse to open when released
P h
=
n o
reverse, immediate open
■
FailSafe test
The functional test is carried out before each 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 prevents the automation from moving
(status
0 5
).
To enable the test:
-
connect the transmitter negative to terminal TX-FSW
-
enable the FailSafe test in advanced programming:
F S
=
Y
The maximum power consumption at terminal 11 is 100 mA.
