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". The photocells consist of a transmitter and a receiver and
must be opposite each other. The photocell is mounted on the wall
using small screws and wall plugs. 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.
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 no photocell connected
LED on constantly = OK
LED flashes = photocell disables control board
Connection between 1 & COM will give:
ignored when gate is opening, when closing if beam is blocked gate
stops then reopens (does not matter when beam is unblocked).
Connection between 2 & COM will give:
when gate is opening block beam gate stops when you un-block beam
gate caries on opening.
When gate is closing block beam gate stops un-block beam gate
reopens.
KEY SWITCH (OPTIONAL)
The system can be operated by key switch. It is possible to operate
only 1 wing or two wings. This depends on how the JUMPERS are
used (connectors: key symbol and COM)
SAFETY EDGE (OPTIONAL)
A safety edge working according to the 8.2 kilo ohm principle can be
connected to the control board, i.e. a 8.2 kilo ohm test resistor is
attached to the end of the safety edge. It ensures that the electric
circuit is monitored permanently. The control board is supplied with
an 8.2 kilo ohm resistor installed. Several safety edges are
connected in series.
Cable cross-section: 0.5 mm
E-LOCK (OPTIONAL)
The control board allows the use of a 12V E-lock. (instructions
included with E-lock).
A support board must be connected for the E-lock on the main
board.
Attach support board next to the transformer on to the baseplate
using screws.
Open its casing and make all necessary electrical wiring.
Plug support board in to where the E-lock symbol is depicted.
