Checking Gate Movements; Preset Functions; Radio Receiver - Nice NAKED NKSL400 Instructions Pour L'installation Et L'utilisation

If it is necessary to adjust limit switch positions more finely, use the
adjustment knobs (fig. 21a) in the gearmotor, as follows:
1. Press ▲ or ▼ on the unit to open or close the door on the basis of
the position to be defined.
2. Remove the lid locking the limit switch in place (fig. 21b).
3. Identify the adjustment knob with the arrow indicating the direc-
tion of the limit switch to be adjusted and turn it half a turn (about
3 cm travel of the gate).
4. Next, on the unit, press ▲ or ▼ again to open or close the door
to adjust the new position. Repeat as necessary until the door
has the desired limit switch.
IMPORTANT! – If it is necessary to define the position of the limit
switch with greater precision, move the door back a few centimeters
while giving the opening or closing commands (▲ or ▼) from the unit
and then send the command in the direction to be checked once
more.

4.5) Checking gate movements

On completion of the recognition of the length of the leaf, it is advis-
able to carry out a number of manoeuvres in order to check the gate
travels properly.
1. Press the [Open] key to open the gate. Check that gate opening
occurs regularly, without any variations in speed. The leaf must
only slowdown and stop when it is between 70 and 50 cm from
the opening mechanical stop. Then, at 2÷3 cm from the mechan-
ical opening stop the limit switch will trigger.
2. Press the [Close] key to close the gate. Check that gate closing
occurs regularly, without any variations in speed. The leaf must on -
ly slowdown and stop when it is between 70 and 50 cm from the
closing mechanical stop. Then, at 2÷3 cm from the mechanical

4.6) Preset functions

The NAKED control unit has a number of programmable functions.
These functions are set to a configuration which should satisfy most
automations. However, the functions can be altered at any time by

4.7) Radio receiver

The "SM" radio receiver connector for SMXI or SMXIS type optional radio receivers has been provided in order to enable the user to control
NAKED from a distance. For further information consult the radio receiver instructions manual. The association between the radio receiver
output and the command performed by NAKED is described in table 6:

Note – if you have already performed manual adjustment and need
to repeat the entire procedure, you may return the limit switches to
their initial condition by turning the adjustment knobs toward the "–"
sign until the micro-switches are tripped (fig. 21c). Then repeat the
entire limit switch adjustment procedure.
Important – If the door is not in the correct position midway along
its travel when the motor is anchored in place and the pin is moved
along the rack, it may be necessary to reduce the position of the limit
switch on one side.
In this case, if the door opens until it hits the retainer, without com-
ply with the set position, turn the adjustment knob (identified by an
arrow indicating the direction in which the door moves) toward the
"–" sign until the limit switch is tripped. After this, oversee adjustment
of the unit again and use precision adjustment if necessary.
if necessary, adjust the door length again.

closing stop the limit switch will trigger.
3. During the manoeuvre, check that the flashing light flashes at a
speed of 0.5 seconds on and 0.5 seconds off. If present, also
check the flashes of the light connected to the S.C.A. terminal:
slow flashes during opening, quick flashes during closing.
4.Open and close the gate several times to make sure that there are
no points of excessive friction and that there are no defects in the
assembly or adjustments.
5. Check that the fastening of the NAKED gearmotor, the rack and
the limit switch brackets are solid, stable and suitably resistant,
even if the gate accelerates or decelerates sharply.
