Autolearning Of The Travel Stroke - Key Automation CT202 24 Instrucciones Y Advertencias Para Su Instalación Y Uso

4.3 - Autolearning of the travel stroke

The first time the control unit is powered up, an autolearning proce-
dure must be carried out to acquire fundamental parameters such
AUTOLEARNING OF THE TRAVEL STROKE AND MAIN PARAMETERS
The decelerations will be those set in the menu, with the same percentage during both opening and closing.
CAUTION: if manual programming of deceleration intervals is required, go to the next table
CAUTION! check that mechanical end stops (compulsory) are present and secure. The motors must
always reach the mechanical end stop
1. Move the gate manually to mid-travel
CAUTION: 2. Before proceeding with programming, use parameter de.f. to select the type of motor to
be programmed (see paragraph 6, configuration of parameter de.f.). If this phase is not completed, this
may cause serious damage to the automation!
3. Press the pushbuttons UP and MENU at the same time for at least 5 seconds until LOP is displayed, then (if
necessary) press DOWN (see figure).
Ensure that motor M1 is activated first; otherwise, press DOWN, turn the power off and invert connections M1
and M2. Repeat the procedure from step 3.
If the first manoeuvre is NOT opening, press DOWN to stop the self-learning process. Then press SBS to re-
start acquisition: the leaf resumes movement in the correct direction
4. Motor M1 opens at low speed until it reaches the mechanical opening end stop.
On reaching the mechanical end stop on opening of M1 motor M2 starts automatically in opening mode (the
display shows LO.P.). If motor M2 moves in closing, stop by pressing DOWN and resume movement using SBS
(the leaf resumes movement in the correct direction)
5. The motor M2 opens at low speed until reaching the mechanical opening end stop.
6. After a couple of seconds, motor M2 starts up automatically at low speed until reaching the mechanical clo-
sing end stop (the display shows LC.L.)
7. On reaching the mechanical opening end stop of M2, motor M1 closes at low speed until reaching the me-
chanical closing end stop, thus completing the programming phase (the display shows LCL)
All the main parameters are set with the default settings by the control unit. To customise the installation, proceed as described in point 4.6
below.
