04. a) Set the contact cam 1 E ↑ (green, fig. 1) to activate the limit
switch
b) Tighten down the fixing screw "A" (fig. 1)
c) For precision adjustment, use screw "B" (fig. 1).

onds to confirm position A0.
LED L8 stays on.

The safety limit switches 2 SE↑ and 4 SE↑ (red, fig. 1) must be set to intervene
as soon as the control limit switch is exceeded.
The safety limit switches 2 SE↑ and 4 SE↑ (red, fig. 1) must be set at the factory
to follow the operating limit switch from a short distance.
After the operation test, check that the fixing screws are positioned correctly.
The additional limit switches 8 P2↑ and 7 P2↑ are zero potential closing contacts
and the additional limit switches 6 P1↑ and 5 P1↑ are zero potential switching
contacts.
The additional limit switch 1 CLOSING (6 P1↓ or 5 P1↓) is used as pre-
liminary limit switch; therefore, it must be set to be triggered when the
door reaches a distance of 5 cm from the ground. The activation of this
limit switch avoids the execution of the "brief inversion" manoeuvre. If the
sensitive edge is activated, it only runs the STOP. This limit switch must
always be connected to the PRE-CLOSE input of the control unit. If it is
not connected, in the control unit it is necessary to bridge the limit switch
3 input with the common 1 input.

7 - Use with MEIN series inverter
The NDCC2301 control unit can pilot gearmotors with a MEIN series inverter on
board.
Having completed the connections as described in the motor's instruction manual,
the inverter is ready to be installed:
1 Memory deletion for sectional or High-speed doors (paragraph 10);
2 Activate inverter function (L7, level 1);
3 Recognition of the connected devices (see paragraph 2);
4 Recognition of limit positions on opening and closing with the use of MEIN
family inverter (paragraph 5).
The standard values are set in the factory. These may be changed via the Oview
programmer or by programing with the keys of the board.
The parameters which may be shown / changed are:
• Speed when opening
• Speed in opening deceleration
• Speed when closing
• Speed in closing deceleration
• Minimum frequency
• Acceleration
• Deceleration
• Emergency deceleration
• Start-up
• Motor warm up
• Alarm and protection management
• Inverter status
For the specifications of the values of each parameter, please consult the function
