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 200mm. 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 description). To enable the "Automatic
closing" function, the Chamberlain failsafe photocell must be installed.
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.
Settings:
In menu P7 + P8 the control has to be set to the connected photo
cells.
For Chamberlain 2-wire photo cells the setting PLS = pulse is
required.
For relay-photo cells select setting RLY = relay.
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
