ACCESSORIES
PHOTOCELLS (OPTIONAL)
The photocells are for safeguarding the gate and must be used. The
fitting location depends on the gate's design. EN12453 specifies that
a pair of photocells must be installed at a height of 200 mm and
activated to "Close"; a second pair must be installed at a height of
200 mm and activated to "Open". A third pair of photocells can be
optionally installed and activated to "Close" and "Open". The
photocells consist of a transmitter and a receiver and must be
opposite each other. The housing of the photocell (plastic) can be
opened using a screwdriver. The photocell is mounted on the wall
using small screws and wall plugs. It is possible to use two different
photocell systems (see Dip switch description). To enable the
"Automatic Closing" function, the Chamberlain failsafe photocell must
be installed. A combination of photocells is not possible. The
Chamberlain failsafe system (2-cable system) has small LEDs (light)
that can be seen from the outside on both sides to indicate the status
of the photocell. Two Chamberlain failsafe photocell models are
available. The one model is ideal for walls lying opposite. The other
model is ideal for the inside of the gate, because fittings are already
available.
Diagnosis at the Chamberlain failsafe photocell
LED constant = OK
LED flashes = photocell disables control board
LED off = no current, incorrect connection or polarity
Diagnosis on the control board
LED off = OK
LED on constantly = control board disables
LED flashes = OK no photocell connected
