5. Choice of the deceleration point in opening:
- The automation will start to open quickly, press therefore the PROG key to start the deceler-
ation phase in opening at the selected point.
(If it is not pressed, in any case the automation slows down starting from a minimum safety distance
to prevent the gate from banging hard when opening).
6. Choice of the deceleration point in closing:
- After a short pause the automation will begin to close quickly, press therefore the PROG key
to start the deceleration phase in closing at the selected point.
(If it is not pressed, in any case the automation slows down starting from a minimum distance of safety to
prevent the gate from banging strongly when closing).
PROCEDURE WITH LIMIT SWITCHES INSTALLED:
1. Start the procedure with the gate at approx. 0.5 m from the opening limit switch.
If the automation closes instead of opening:
1. stop the gate stroke (through photocells or by pressing the STOP key)
2. remove the power supply to the electronic board and reverse the direction of
the gate using the DIP SWITCH n. 8
3. Before to restore the power to the electronic board, attend 10 seconds
4. repeat the programming by pressing the PROG key (6 sec. ca.) until the automa-
tion starts to open
2. Press without releasing the PROG button (6 sec. ca.) till the DL2 LED starts flashing (orange):
3. The automation starts to open slowly in search of the opening limit switch;
4. Once the opening limit switch has been reached, the automation slowly begins to close in
search of the closing limit switch;
5. Choice of the deceleration point in opening:
- The automation will start to open quickly, press therefore the PROG key to start the deceler-
ation phase in opening at the selected point.
(If it is not pressed, in any case the automation slows down starting from a minimum safety distance
to prevent the gate from banging hard when opening).
6. Choice of the deceleration point in closing:
- After a short pause the automation will begin to close quickly, press therefore the PROG key
to start the deceleration phase in closing at the selected point.
(If it is not pressed, in any case the automation slows down starting from a minimum distance of safety to
prevent the gate from banging strongly when closing).
- HOW TO CHANGE THE DECELERATION POINTS
If you want to change the deceleration start points, just press again the PROG key briefly (1 sec.) and the
automation will start to open again and will allow you to insert the new deceleration point in opening
and closing by pressing the PROG key again in the desired points.
WARNING:
• During the memorization, the intervention of the safety devices (photocells, sensitive edge
or stop input) stop the automation and pause the procedure itself; to resume, it will be
necessary to press only and exclusively the PROG button.
Please remember that an obstacle during saving is interpreted as a mechanical limit stop
(the system does not start any safety operation, it just stops the motor)
7. K124MA CHARACTERISTICS
TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening/closing of the automation can be controlled by means of a timer that has a free N.O.
output contact (relay). The timer must be connected to terminals 4 - 6 (OPEN/CLOSE button) and can
be programmed so that, at the desired opening time, the relay contact closes until the desired closing
time (when the timer's relay contact opens, enabling the automatic closing of the gate).
Note: the automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
