been reached, the control unit stops the movement. Another command causes the gate to start moving again in the opposite direction.
7.2.3 - STEP-BY-STEP 1 OPERATION:
When the command is activated (LED L1 lit), using both the radio control and the low voltage push-button panels to operate the gate,
the following will occur: the first command controls the opening until the motor time limit expires or when the end of the opening stroke is
reached, the second impulse commands the closing of the gate; if a command is sent before the motor time limit expires or when one of the
two limit switches is reached, the control unit always stops motion both in the opening and closing phases (even if the pause time has been
previously programmed). Automatic closing is not carried out. A further command determines 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
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 execute the gate opening cycle 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.
Important note: Inputs DS1 and DS2 (NC) are factory bridged. To wire the photocells, remove the jumpers from the corresponding inputs.
7.2.9 - OPENING AND CLOSING LIMIT SWITCHES:
The control unit allows for the connection of N.C. Opening and Closing limit switches. The intervention in the respective operating phases
causes the immediate stop of the motion with the correspondence between limit switches and Motor 1 and 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. Use of the Encoders improves the Obstacle Detection function and
guarantees improved precision during execution of the manoeuvre.
Obstacle detection does not work with automatisms without encoder.
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.
FUNCTIONING
- Light off:
closed
- Light on:
open
- Light flashes slowly:
motion when opening
- Light flashes rapidly:
motion when closing
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.
