6 Control board
6.1 Technical description board ZBX241
This control board is powered by 230V a.c. across terminals L1 and L2, and is protected by a 1A fuse on the main power line.
Control systems are powered by low voltage and protected with by a 1.6A fuse.
The total power consumption of 24V accessories must not exceed 40 W.
Fixed operating time of 90 seconds.
Photocells can be connected to obtain:
- Re-opening during the closing cycle;
- Partial stop: shutdown of moving gate, with activation of an automatic closing cycle;
- Total stop: shutdown of gate movement without automatic closing; a pushbutton or radio remote control must be actuated to
resume move ment;
The board, moreover, integrates and independently runs a safety function capable of detecting obstacles that hinder movement:
during opening: the gate stops and the automatic closure is activated;
during closure: the gate inverts its direction until it is completely open, after which it closes automatically.
Warning! after three consecutive inversions, the gate will remain open and automatic closure will be discontinued. Toclose
the gate, use the radio remote control or the push-button.
Other functions available:
Automatic closing: The automatic closing timer is automatically activated at the end of the opening cycle. The preset, adjustable
automatic closing time is automatically interrupted by the activation of any safety system, and is deactivated after a total stop
command or in case of power failure;
- Partial opening function: opening of the gate to the desired position for pedestrian passage, which can be adjusted on the
trimmer;
- Detection of obstacles: this function cancels every command if the photocells (in whatever safety function connected) detect
an obstacle with the gate at the limit position;
- "Human presence" opera tion;
- Flashing light activated before opening and closing cycle begins;
- Selection of command sequence: open-close-reverse, open-stop-close-stop or open only.
Adjustments: automatic closing time, partial opening time and amperometric sensitivity.
IMPORTANT:- the opening of the unblock panel arrests the motor.
- Shut off the mains power and disconnect the batteries before servicing the inside of the unit.
