Limit Switch Adjustment; Troubleshooting - DITEC 52E Manuel D'installation

F1 - F2

4. LIMIT SWITCH ADJUSTMENT

1. Set the deceleration ramps at zero (P3 - P4)
2. Set the limit switch (C) on the gearmotor so that the door stops about
200/300mm from its closure point.
3. Set the opening limit switch (A) at the opening point.
4. Set the deceleration limit switch (B) so it is triggered at about ¾ of the
opening stroke.
5. Set the opening and closure speeds using trimmers (P1) and (P2) respectively.
6. Set the trimmers of the deceleration ramps - (P3) for opening and (P4) for
closure - to ensure the door stops at its actual "open" and "closed" positions.

Check
• Reduce opening speed.
• Check power supply.
• Check power supply wiring.
• For Sector Reset doors, connect the brake resistance and set
the item on the advanced menu to "YES".
• Switch off the control panel, wait 3 minutes and reconnect the
power supply.
• If the error reoccurs, check that the voltage on the BUS is lower
than 360 V.
• Switch off the control panel, wait 3 minutes and reconnect the
power supply.
• Check the control panel power supply voltage.
To reset the control panel follow the procedure:
• DIP2 in ON
• push STOP (the control panel goes in the "programmin menu"
showing the data already set)
• scroll the menù till the step "COMMAND MODE" and set LIMIT
