Control Board - CAME BK Series Installation Manual

6 Control board

6.1 Technical description
The control board is powered with (120V a.c.) across terminals L and N and is protected by fuse on the main power line
(see table).
The control systems are powered by low voltage (24V) and protected by a 1A fuse.
The total power consumption of the 24V accessories must not exceed 20W.
The operating time (interval) is fixed at 150 seconds.
The photocells can be connected and set to re-open during the closing phase, re-open during the opening phase, partial stop,
total stop and obstacle sensing when motor is not running.
Note: If a normally closed safety contact (2-C1, 2-CX o 1-2) is opened, this is indicated by the flashing LED (ref. point 9,
main components).
The ZBKE board autonomously controls a safety function that senses any obstacles which:
- when opening, stops the gate and triggers automatic closing;
- when closing, inverts the direction of movement of the gate until it is fully opened and consequently, automatically closes it.
Warning! After the gate's direction is inverted three consecutive times, the gate remains opened excluding the automatic
closing function – use the remote control or push button to close the gate.
The board also includes other selectable functions, such as: automatic closing, partial opening, pre-flashing of the opening
and closing phases, "maintained action movement", phase or courtesy lamp, partial stop or re-closing during opening phase,
master-slave and the following command: open-stop-close-stop, open-close-inversion or only open.
The automatic closing and partial opening times are adjustable.
Warning! Before doing any work inside of the unit, shut off the power supply.
