Chamberlain LiftMaster CB11 Instructions And Electrical Set Up page 9

ELECTRIC LOCK (OPTIONAL) 600022 (24V)
An electric lock can be connected to the control board using terminals
10 and 11.
Cable cross-section: 0.5 mm 2
Voltage: 24 volts AC/DC.
GATE MONITOR / LIGHTING (OPTIONAL)
A 24V/3W light bulb can be connected to monitor the status of the
gate. Alternatively, a yard lighting system can be used by adding a
relay (accessory). Cable cross-section: 0.5 mm
Voltage: 24 V
FLASHING LAMP (OPTIONAL) FLA24-2
A flashing lamp can be connected to the control board. It warns when
the gate is being moved. The flashing light should be fitted as high as
possible and in good clear view. The control board emits a constant
signal that the lamp converts to a flashing signal.
Cable cross-section: 0.5 mm 2
Voltage: 24 V 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.
PUSHBUTTON / KEY-OPERATED SWITCH (OPTIONAL)
The control board / drive can be activated using various inputs.
This can be done using a transmitter or keyswitch (terminals 17
and 20).
Transmitter = see "Teaching the transmitter"
Switch input 1 = input control 1 normal operation
Switch input 2 = input control 2 active for special settings
(see Dip switch description)
EMERGENCY STOP (OPTIONAL) 600084
A switch can be connected to stop or disable the unit. The
movement of the wings is stopped immediately. Terminals 19 and
20 must be bridged if no switch is installed.
CONNECTION FOR CONTACT LOOP (OPTIONAL)
A contact loop evaluation unit (203292 1-channel, 203308 2-
channel) can be connected to the control board. A 2-channel
evaluation unit can be used to evaluate 2 channels separately or in
combination.
Note: The description only refers to the separate evaluation of
each loop. If a 2-channel evaluation unit is used, two consecutive
loops can be laid to detect the driving direction of vehicles. Further
connection combination options are then possible.
To open the entrance or exit
Connection to terminals 17 + 20. Dip switch in car park function.
Automatic closing enabled (recommended).
For protection in the swinging range of the gate
Connection to terminals 19 + 20 (stop). Relay output of the
evaluation unit when using failsafe photocells NO (closer). If relay
photocells are used as NC (opener). Automatic closing function not
recommended.
Attention: The only safeguard that is not permitted according
to EU standard!
24 VDC - OUTPUT
For relay infrared senors or other devices (e.g. receivers)
max. 500 mA
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.
