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
Cable cross-section: 0.5 mm
Voltage: 12/24 volts AC/DC.
Do not use any fixed copper lines. Do not lay any 230 volt cables in
parallel and do not lay any 2 cables in the same cable trunking.
JUMPERS
Programming of failsafe photocells model 771E/770E
1.Before the Initial Setup
2.When connecting or removing photocell(s)
- Switch off control board ( disconnect from current)
- Slip jumper on designated pins
- Dipswitch 5 to "ON"
- Connect photocell(s) according illustration
- Reconnect control board, wait short-time
- Pull jumper, wait short-time
Done! (The number of photocells connected are stored)
Programming of relay photocells such as 100263
The control board must be disconnected from the mains for a few
seconds. All terminals to which no photocell is connected must be
bridged with COM. (21-24, 22-24, 23-24). The power supply for the
relay photocell of terminals 15-16. Dip switch 5 must be at OFF. The
jumper must be unplugged.
Note: Relay photocells are no longer permitted for new installations
as per EN12978, because they cannot perform self-checks (failsafe).
Operation without photocells
DANGER: Not permitted for normal operation. In this case contact
strips must safeguard the gate.
The control board must be disconnected from the mains for a few
seconds. Terminals 21-22-23-24 must all be bridged. Dip switch 5
must be at OFF. The jumper must be unplugged.
Note: It is not possible to combine different photocell models.
