9. 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. Detec-
tion devices used as safety accessories (e.g. sensitive
edges) to protect against a hazard, must comply with
standard EN 12978.
Using relay photocells with NC contact. If multiple
photocells are used, the contacts must be connected in
series. If inputs IN4 and IN5 on the board are not used,
they must be bridged to the GND terminal (or to the
output programmed as
FAIL-SAFE
, if enabled).
Position and connect the photocells according to their
required use:

FUNCTIONAL TEST (
FAIL-SAFE
)
If enabled, the functional test is carried out before
each movement and the board momentarily inter-
rupts the power supply to the transmitters and checks
the change in status of the input. If the test fails, the
board generates an error and prevents the automation
from moving.
1. Connect the negative of the transmitter to the
negative of output OUT1 or OUT2.
2. Enable the
FAIL-SAFE
test on the output used:
