Learning The Work Time; Learning With Timed Operating Mode; Board Sf2N For Learning With Encoder Or Limit Switch + Reverser - O&O DEC-BT Manuel D'installation Et D'utilisation

ATTENTION!!! Make sure the learning phase is not obstructed by friction or other obstacles. In this programming phase, there
must be no interference with the travelling movement of the gate. Considering that the safety devices are disabled, you need
to make sure nobody and no vehicles are near the manoeuvring area of the gate during the learning phase.
Make sure the leaves are closed and hold button P1 down for at least 3 seconds: The prog LED will start flashing and leaf 1 will start to
open. By pressing button P1 or START a number of times (consequently providing pulses), the following sequences will be performed:
1st pulse of 3 sec. leaf 1 starts to open
2nd pulse: leaf 1 opening slowdown
3rd pulse: leaf 1 end-of-opening and leaf 2 starts to open
4th pulse: leaf 2 opening slowdown
5th pulse: leaf 2 end-of-opening and leaf 2 starts to close
6th pulse: leaf 2 closing slowdown
7th pulse: leaf 2 end-of-closing and leaf 1 starts to close
8th pulse: leaf 1 closing slowdown
9th pulse: leaf 1 closing ends
NB.: If you wish to eliminate the slowdown function in some phases, you need to wait for the leaf to reach the end-of-travel position and
then press button P1 or START twice consecutively.
10. BOARD SF2M FOR LEARNING WITH ENCODER
The DEC-BT control unit has a connector to fit the functions board for 2 motors "SF2M" that allows you to amplify the available inputs to
manage automated devices complete with limit switch and reverser devices to limit the impact forces.
For drive model Zero12 equipped with Encoder, there is a specific programming function of the stroke and the slowdown spaces that the
control unit will save when reading the pulses sent from the encoder.
In addition, the automatism is able to recognise the presence of obstacles and reverse direction both in opening and closing. When the
anti-crushing system triggers it causes a brief reversal of direction (2 seconds) both in opening and closing.
The fitter can adjust the torque and slowdown speed trimmers to adjust the tripping sensitivity of the encoder or of the reverser so that
the automated device is installed in compliance with standard EN12453.
Checking the connections
Release the motors, move the leaves manually, making sure the limit switches work correctly, adjusting them if necessary, so that the
related LEDs switch off only when the leaf is near the required limit switch position. Considering that the inputs are the N.C. type, you
need to install jumpers on the limit switches that are not used (LED on).
The reverser and the Encoder are pointed out by LEDs SGN1 and SGN2 and with the motor stopped, it is normal that they may be ON
or OFF, whereas during the manoeuvring phases, they must be ON steady.
If these safety devices are not used, leave the inputs free.
Selecting DIP SWITCHES 1-2 (SW3) to manage the learning function based on the type of drive installed.
OFF-OFF: Timed operating mode with limit switches installed, when they trip they stop the movement.
OFF-ON: Timed operation with reverser and limit switches installed, when the FCA trips it stops the movement while the FCC disables
the reverser and continues to close for another 3 seconds.
Use this setting if the gate must press firmly when closing.
The FCC must therefore always trip just before the gates closes completely.
ON-OFF: Timed operation with reverser and limit switches installed, when they trip they stop the movement.
ON-ON: Operation with Encoder (therefore without limit switch) specific for Zero12 with Encoder.
In the Zero12 versions with lock, do not jumper the limit switches. With the Zero12 motor without lock, jumper all the limit
switches.
Connections:
+V = +5 Power supply Reverser or Encoder (green wire)
SGN = Input of Reverser or Encoder signal (white wire)
COM = Negative power supply of Reverser or Encoder (brown wire)
FCA = N.C. input of opening limit switch
FCC = N.C. in put of closing limit switch
COM = Mutual negative of limit switches
Quick connections:
JC8-JC9: plug-in connectors type RJ12 for the quick connection of the limit
switch and reverser of the motors complete with this connection.
