6 Control board
6.1 General description
FUSE TABLE ZD2
To protect:
fuse:
Motor 10 A-F
Control board (line) 1,6 A-F
Accessories 1.6 A-F
Command devices 3,15 mA-F
6.2 Main components
1) Power supply terminals
2) Endstop terminals
3) Motor terminals
4) Encoder terminals
5) Accessory fuse
6) Card fuse
7) Button for memorising the radio code
8) Radio-code signalling LED indicator
9) 230V-power signalling LED
10) Control and signalling LED group
11) Function selector DIP switch
12) Socket for connecting the remote control’s radiofrequency
card
13) Antenna terminal
14) Accessories’ and command device’s terminals
15) Motor fuse
16) Line fuse
17) Setting trimmer
18) Battery charger (LBD2) connecting terminal boards
19) Transformer-connecting terminal board
Use 230V AC to power the electronic card using the L-N
terminals, at a max 50/60Hz frequency.
Use 24V to power the command devices and accessories.
Careful! The accessories cannot exceed 37W of overall power.
The card is fi tted with an amperometric device which constantly
monitors the motor’s drive. When the gate runs into an obstacle,
the amperometric sensor immediately detects the overload on
the drive and so inverts the gate’s movement:
- opens it if it is closing
- closes it if it is opening
Warning: after 3 obstacle detections, the gate stops when in
opening-mode and excludes automatic-closing mode; to regain
movement press the command button or use the remote control.
All connections are protected by quick-fuses – see table.
The card handles the following functions:
- Automatic closing after an opening command;
- Warning light pre-fl ashing;
- Obstacle detection when gate is still at any point;
- Constant monitoring of photocell operations.
- Opening/closing;
- Opening/closing in maintained action mode;
- partial opening;
- total stop.
Apposite trimmers regulate:
- The automatic closing’s running time;
- The partial opening;
- The amperometric device’s detection sensitivity, in both normal
and brake modes;
- the speed of both the normal gate run and the brake mode run.
Warning! Before acting on the machinery, cut off the main power
supply and disconnect any emergency batteries.
