Adjusting The Limit Switches - Daspi SKY C 650 Manuel D'instruction

the chain into housing "H1" and run it half way along the sliding guide
(fig. 6).
take the end of the chain that comes out of housing "H" and insert it
into housing "H1" , making sure that the chain engages correctly with
the gears, and run it along until the two ends are about 100 mm apart.
(fig. 7).
open the two joints at the ends of the chain and assemble the pulling
plate "l " , inserting the pins of the joints into the holes on the plate, so that
the two joints are perfectly closed.
WArNINg: position the plate as in the drawing (fig.8).
prepare the front bracket "s4" by fitting screws "V1" and nuts "d1" , slide
in the bracket to the stop, sliding nuts "d1" in their respective housings
"a" on the guide and screw "V3" of the chain-tightener in the appropriate
hole on bracket "s4" , then attach screws "V1" (fig. 9).
on screw "V3" fit spacer "M" and nut "d3" and adjust the chain tension
provisionally by tightening nut "d3" (fig. 9)
WArNINg: if the chain is too tight this could increase noise and may
damage or break the mechanical parts of the motorisation.
PRE-ASSEMBLEd VERSIon 1.5 - 3 M
on a level surface, open and align the parts of the guide that have been
supplied already assembled with the chain.
connect the various parts by inserting, into the appropriate housings
"a" of the guide, nuts "d1" of brackets "s1" and fasten screws "V1" ,
making sure that the parts are positioned exactly head to head (1.5 m
only) (fig. 2).
assemble bracket "s2" on the motor support using the appropriate
screws "V2" and washers "r1" , insert the previously assembled guide
in the appropriate housing "B" and fasten it down, making sure that the
chain has engaged properly with motor pinion (fig. 3-7).
Make sure the chain engages properly with the chain-tightening gear and
adjust the chain tension provisionally by tightening nut "d3" (fig. 9)
WArNINg: if the chain is too tight this could increase noise and may
damage or break the mechanical parts of the motorisation.
Carefully check the structure on which the gear motor is to be mounted,
to make sure it is solid; if not, reinforce it.
With the door closed, at the top on the inside draw a vertical line passing
through the centre of the door and extend the line to the wall above (fig.
10). open the door to measure the point of maximum space requirement
at height "K" reached by the door (fig. 11). For type B overhead doors,
on the wall, draw a horizontal line perpendicular to the vertical line,
10mm above point "K". (fig. 11). For type a sectional doors, on the wall,
draw a horizontal line perpendicular to the vertical line, 10mm above the
spring-holder shaft (fig. 10). position bracket "s5" , aligning it with the
centre of the vertical line and with the lower edge on the horizontal line,
fasten it to the wall or to the lintel using appropriate dowels and screws
or by top quality welding (fig. 10). Mount the assembled gear motor by
first connecting bracket "s4" to bracket "s5" using screw "V4" , washer
"r3" and nut "d4" , it is not necessary to fully lock the nut (fig. 12). Bring
the sliding guide into a horizontal position, placing the gear motor on
a suitable support (fig. 13). in the corresponding housings "a" slide a
nut "d1" on the motor side and, inserting spacers "n" mount ceiling
brackets "J" using screws "V1" (fig. 14). attach brackets "J" firmly to the
ceiling using suitable screws and expansion plugs.
We recommend installing a pair of "J" brackets for every joint in
the guide; for a single piece 3 metre guide a pair of "J" brackets is
sufficient. using screws or by welding, attach bracket "s6" to the top
inside edge of the door, aligning it with the centre and fit arm "o" using
the corresponding screw "V5" and nut "d4" (fig. 15). For lightweight
overhead doors we advise reinforcing the bracket attachment point.
Make the electrical connections following the instructions for the
electronic control unit.
the sliding guide is designed for passing the power supply cables (fig.
16).

open the door manually as far as it will go.
Make a gear motor opening operation using the "person present open"
switch p.open (see the electronic control unit diagram below) to align
housing "d" of shoe "c" with arm "o" (fig. 17)
use a permanent marker to mark the last link that can be seen from
under the motor support on the left side of the chain (fig. 18). using
the "person present close" button p.close (see the electronic control
unit diagram below) close by about twenty centimetres and by simply
pressing, on the chain install the cam to trigger the limit switch at the
position corresponding with the previously marked link (fig. 20) making
sure that the marked part coincides with the start of the cam; the first
time the limit switch triggers will determine when the door starts to
decelerate, the second time it will stop the motor (fig. 20).
N.B. during the normal cycle, if the motor goes beyond the threshold
setting, it stops and changes direction, whether opening or closing; if it
is in the deceleration phase this safety device does not trigger in order
to allow the door to completely close.
take the door to the closed position.
Make a gear motor closing operation using the "person present close"
button p.close (see the electronic control unit diagram below) to align
housing "d" of shoe "c" with arm "o" (fig. 17)
use a permanent marker to mark the last link that can be seen from
under the motor support on the right side of the chain (fig. 18). using
the "person present close" button p.open (see the electronic control
unit diagram below) open by about twenty centimetres and by simply
pressing, on the chain install the cam to trigger the limit switch at the
position corresponding with the previously marked link (fig. 19) making
sure that the marked part coincides with the start of the cam; the first
time the limit switch triggers will determine when the door starts to
decelerate, the second time it will stop the motor (fig. 20).
N.B. during the normal cycle, if the motor goes beyond the threshold
setting, it stops and changes direction, whether opening or closing; if it
is in the deceleration phase this safety device does not trigger in order
to allow the door to completely close.
to housing "d" of shoe "c" connect arm "o" using screw "V5" and
nut "d4" without locking the nut right down in order not to damage
articulation of the arm (fig. 21)
N.B. remove the door lock or make it unusable in order to prevent
damage to the door or to the automation.
Warning: If the door to be automated has a pedestrian door you must
install a safety switch in series with the STOP contact on the control
unit.
carry out an opening – closing manoeuvre to make sure the limit
switches have been adjusted correctly.
the control unit is designed with a safety lapse of 2 seconds, after which
it automatically stops if the limit switch has not triggered for the second
time; the motor stops and the courtesy lamp flashes for 4 seconds to
indicate that limit switch adjustment could be improved.
if necessary make a micrometric adjustment to the limit switches by
loosening screws "V6" and shifting microswitch "p" (fig. 22).
use screws "V7" to attach the safety guard (fig. 23).
carry out the manual release manoeuvre to check operation.N.B. if the
door to be automated is the only escape route towards the outside it
must by fitted with the "OPTIONAL " external release device kit.
Fit all the compulsory safety devices and instruct the people who will
use the automation regarding the controls, safety devices, emergency
operations and hazards arising from use of the automation.
complete the technical forms and comply with any obligations required
by the legislation in force.
