DEFINITION OF OPENING DIRECTION AND
OPERATION OF LIMIT-SWITCH LEDS

Power up the system and set the opening direction on the
board (see par. 5.5.1).

If opening direction is RIGHTWARD (

):

OPENING limit-switch LED  =  

F C 1

CLOSING limit-switch LED  =  

F C 2

If opening direction is LEFTWARD (

):

OPENING limit-switch LED  =  

F C 2

CLOSING limit-switch LED  =  

F C 1

6. START-UP

6.1.

ELECTRIC CONNECTIONS

Make all electrical connections to the board as in chapter 5,
including earthing of the operator  (Fig. 39).

6.3.2.

Inductive limit-switch

Operator 844 has an inductive limit-switch which detects the
transit of the two steel plates fitted on the top of the rack.
Procedure for correct positioning of the two supplied steel
plates:
1)

Assemble the limit-switch by centring the plate with respect
to threaded pins of the support (Fig. 42).

2)

Check if the operator is in manual operating mode (see
chapter 8).

3)

Manually move the gate to opening position, allowing 2 - 5 cm
from the mechanical stop limit.

4)

Allow the plate to move on the rack in opening direction until
the relevant LED goes OFF (Figs. 22 and 42); next, move the
plate forward by about another 45 mm and secure it to the rack
by tightening the screws.

5)

Manually move the gate to closing position, allowing 2 - 5 cm
from the mechanical stop limit.

6)

Allow the plate to move on the rack in closing direction until the
relevant LED goes OFF (Figs. 22 and 42); next, move the plate
forward by about another 45 mm and secure it to the rack by
tightening the screws

Attention: due to the powerful magnetic fields the supplied
magnets produce, the magnets can damage magnetic band
components (credit cards, magnetic tapes, floppy disks, etc)
and electronic and mechanical equipment (e.g. watches,
LCD screens). We advise you not to bring them near to objects
that could be damaged if 'immersed' in a magnetic field.

Notes on magnet positioning

To ensure correct operation, allow at least 2 cm from the
mechanical stop limit in the gate stop position. Carry out this
check after determining the values of the pre- and post-limit
switch decelerations (see par. 5.5.2.) and after running at least
one complete cycle of the automated system.

The distance between the limit-switch and magnets must
befrom 5 to 12 mm.

Magnets should be fitted on the rack and not on the fixing
screws. If necessary, position the magnet at the side of the
screw and adjust decelerations (parag. 5.5.2) in order to
obtain the correct stop point

6.3.

DETERMINING THE STOP POINTS AT TRAVEL LIMIT

Operator 844 has a limit sensor switch which, by detecting the
transit of a reference applied to the rack, commands the gate
motor to stop. The device can be MLS (fig. 41) or inductive (fig.
42).

6.3.1. MLS limit-switch

The MLS limit sensor switch detects the transit of two magnets
fitted on the side of the rack facing the operator.
Procedure for correct positioning of the two supplied magnets:
1)

Check if the operator is in manual mode (see chapter 8).

2)

Manually take the gate to opening position, leaving 2 - 5
cm from the travel limit mechanical stop.

3)

Fit the magnet (without removing the protective film from
the adhesive side) on the side of the rack facing the
operator, aligning the upper edges. Slide the magnet on
the rack in opening direction until the relevant LED goes off
(Fig. 22 and 41), then move the magnet forward a further
45 mm.

4)

Manually take the gate to closing position, leaving 2 - 5 cm
from the travel limit mechanical stop.

5)

Fit the magnet (without removing the protective film from
the adhesive side) on the side of the rack facing the
operator, aligning the upper edges. Slide the magnet on
the rack in
closing direction until the relevant LED goes off (Fig. 22 and
41), then move the magnet forward by about a further 45
mm.

6)

Take the gate to its halfway travel point and relock the
system (see chapter 9).

7)

Find out the desired pre- and post-limit-switch deceleration
values (see parag. 5.5.2) and run the automated system
for at least one complete cycle.

8)

Check if the gate stops at about 2 - 5 cm from its mechanical
stop point. If necessary, correct the position of the magnets
and check if the stop point is correct.

9)

Mark the position of the magnets on the rack, and remove
them.

10) Clean the rack on its fitting points, remove the film on the

adhesive parts of the magnets (fig. 41 ref. 1) and re-
position the magnets with the adhesive strip in contact
with the rack (fig. 41 ref. 2).
