MANUAL PROGRAMMING (T21 - T31)
Manual programming is mandatory in the following cases:
- control unit T21 or T31 controlling motors with incorporated limit switches or limit switches connected to the motor
in series (fig.3)
- control unit T31 connected to motors without limit switches (fig.4)
In the first instance, the control unit memorizes a "safe" work time because the stopping, at the end of the manoeuvre,
is managed by the limit switches.
In the second instance, the stopping of the motor is caused by the expiration of the time memorized; we recommend
using mechanical stops and a control unit (T31) with internal torque adjustment.
Procedure:
1 - Shut off power supply to control unit
2 - Position the gate at mid-travel.
3 - Press PROG/STOP button
4,5,6 - Switch on power to control unit by keeping the PROG./STOP button (part 6 of fig.1) pressed for at least 3 seconds.
Programming LED LD1 comes on. The same function can be obtained by holding the PROG./STOP button (part 9 of
fig.1) down, shorting the reset pins (part 15 of fig.1) for a moment, then releasing the PROG./STOP button when LED
LD1 comes on.
7 - Press pushbutton P/P: the rolling gate should move to close. If it moves to open, stop the programming procedure
and exchange the motor wires, then begin again from step (1).
8 - When the gate is closed press pushbutton P/P once more.
9 - After a short pause, the gate will move to open.
10 - When it has opened all the way, press P/P.
11 - Now that the gate is open you can either wait for the desired pause time to expire or (if you are not using automatic
re-closing) you can go straight to the next step.
12 - Press the P/P pushbutton to close the gate.
13 - When it has closed all the way, press P/P.
14 - Led LD1 will go off, signalling the end of the programming procedure.
