stops motion. When opening after the pause time, it does not automatically close the door (even if the pause time has previously been
programmed). A further command determines the resumption of motion in the opposite direction.
7.2.4 AUTOMATIC CLOSING:
The control unit can be set up to close the gate automatically without sending any additional commands.
The selection of this type of operation is described in Pause time programming mode PAUSE TIME.
7.2.5 PEDESTRIAN OPENING:
The control unit allows, using both the remote control and the Ped input button, the operation of the Motor no. 1 only, for a programmable time.
7.2.6 SINGLE LEAF:
Despite being utilized in the configuration for a 2-operator gate opener, the control unit allows the Pedestrian/Single Leaf pushbutton to start
exclusively Operator no.1, in accordance with the programmed stroke.
7.2.7 EMERGENCY STOP INPUT:
The control unit allows the connection of an emergency stop pushbutton (NC). Pressing this pushbutton
irrespective of the current operating mode of the control unit will cause immediate stopping of the gate movement.
An additional gate movement command will be valid provided the emergency stop input is deactivated and, in any case the control unit will
reverse the motion of the automatism with 5 seconds pre-flashing.
Important Note: Jumper this input if it is not to be used.
7.2.8 PHOTOCELLS:
Photocells can be powered by and connected to the control unit in accordance with directive EN 12453.
DS1 Input (NC):
Tripping of the photocells during opening is disregarded, while during closing it causes reversal of the direction of
movement.
DS2 Input (NC):
Tripping during opening causes momentary stopping of the gate; once the safety is freed the control unit resumes the
opening movement. Tripping during closing causes reversal of the direction of movement.
Programmable input DS3 (NC):
Tripping during opening causes reversal of the direction of movement. Tripping during closing is
disregarded.
To allow operation in compliance with EN 13849-1 Category 2 a photocell test is performed before each movement. In order to perform this
test it is essential to power the transmitter of each pair of photocells on the specific “Photocells Power and Control” output (outputs 3 and
5 of terminal strip CN2), while the receiver of each pair must be powered via the “Users Output” (outputs 14 and 15 of terminal strip CN2).
The control unit enables the movement only if the test is passed; if it is not, the control unit inhibits all movements and an alarm condition
is signalled by blinking of all the programming LEDs on transmission of each command.
7.2.9 OPENING AND CLOSING LIMIT SWITCHES:
The control unit allows for the connection of N.C. Opening and Closing limit switches. Tripping in the associated operating stages causes
immediate stopping of movement with correspondence between limit switches and motor 1 or 2.
Important note:
Do not jumper these inputs if they are not used.
7.2.10 ENCODER MOTOR 1 AND MOTOR 2:
The control unit allows the connection of an Encoder for each motor. The use of Encoders improves Obstacle Detection and ensures
greater precision during the execution of manoeuvres.
7.2.11 INDICATOR LIGHT:
The control unit allows a 24V DC indicator light to be connected to display the status of the gate opener.
- Light off:
gate closed
- Light on:
gate open
- Slow blinking:
opening movement;
- Rapid blinking:
closing movement.
7.2.12 OPERATION WITH TIMER:
The control unit allows a timer to be connected in place of the open – close push-button.
E.g.: at 08.00 am the timer closes the contact and the control unit commands an opening movement; at 06.00 pm the timer opens the
contact and the control unit commands a closing movement.
From 08.00 am – 06.00 pm at the end of the opening cycle, the control unit disables the flashing light, automatic closing and the remotes.
7.2.13 ELECTRIC LOCK CONTROL OUTPUT:
The control unit features an output to control a 24V DC 15W max. electric lock. The command is switched on at each initial opening
movement for a period of 2 seconds.
7.2.14 BUFFER BATTERY:
The control unit is equipped with a built-in 24 V maintenance battery charger.
The control unit allows the connection of a buffer battery of 7Ah recommended capacity, which will allow a number of emergency manoeuvres
at reduced speed. The flashing light, if present, in the absence of mains voltage, will work only for the first 4 seconds of the manoeuvre.
