Use 230V A.C. 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 20W of overall power.
The photocells may be set up for re- opening during closing (2-
C1), partial stop, total stop and obstacle detection when motor
is stopped.
Note: when a normally closed safety contact (i.e. 2-C1, 2-C3 or
1-2) is opened, the signalling LED starts to fl ash (ref. point 11,
main components).
The optical reader inverts the gate’s direction of travel when it
detects and obstacle during its opening and/or closing move-
ment.
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;
The following command modes are possible:
- Opening/closing;
- Opening/closing in maintained action mode;
- partial opening;
- total stop.
Apposite trimmers regulate:
- The automatic closing’s running time;
- The partial opening;
Warning! Before acting on the machinery, cut off the main power
supply and disconnect any emergency batteries.
