Daspi PUNTO, Instruction Manual

Page: 7 / 16

If a flat solid base is already available on the ground, the
barrier can be fixed directly to the base by screws and
fixing plugs without using the “Ps” plate.
Unscrew the 2 screws “V1” by the supplied Allen key
“CH1”. and remove the “Cp” protection cover and the front
door to gain access to the internal cabinet of the barrier
(picture 2).
Once the concrete has fully set, position the PUNTO barrier
onto the “Ps” plate or onto the fixing plugs and tighten the
nuts supplied “D” or the plug screws (picture 3). Barrier
must be levelled in up right position and turned according
to boom selected direction.
inVerTing The bArrier opening DirecTion
PUNTO barrier is supplied for opening in an anticlockwise
direction picture 4.
To invert the opening direction proceed as follows.
Remove the boom from the barrier before doing the
operation of inverting its way of opening from position “A”
of the lever “Ls” the spring “Mb” by removing the screw
“Vm” (picture 4).
Carry out an emergency or manual manoeuvre (see
paragraph Emergency or manual manoeuvre) and turn
the
lever “Ls” clockwise by 90° Reassemble the balancing
spring “Mb” in position “B” and lock the “Vm” screw
(picture 5).
bArrier Arm ADjusTmenT AnD bAlAncing
Warning: when boom is down, the spring Mb must be
under tension (pic 4 and 5); when boom is up, the spring
Mb but be released.
Assemble the barrier boom and block it. Make an emergency
or manual manoeuvre (see paragraph Emergency or
manual manoeuvre) checking that the boom, from its
horizontal position, goes up slowly. In case the boom
doesn’t go up, (after the arm has been brought to the
up right position to unload the spring) Adjust the spring
adjuster “T1” (pic. 4-5) increasing the spring tension.
ADjusTing The mechAnicAl sTops
Carry out an emergency or manual manoeuvre (see
paragraph Emergency or manual manoeuvre) and bring
the arm to a vertical position.
Using two 17 mm spanners loosen the locking nut “D1”
and screw in or out the adjusting screw “F1” until the
desired vertical stop position is obtained and then tighten
the nut “D1” (pic. 4-5).
Bring the barrier arm to a horizontal position, loosen
the nut “D2” and adjust the stop “F2” until the desired
horizontal stop position is obtained and then tighten the
nut “D2” (pic. 4-5).
Once the above operation is terminated, carry out a
manual opening and closure manoeuvre to check that the
mechanical stops are in the correct position. Be sure that
in closing position, the switch “Ms1” has to be touched
by cam “Cs”. If not, adjust the cam "CS" unscrewing screw
“V2” until the cam touches the micro switch “Ms1” (pic.
6)
elecTricAl connecTions
Carry out electrical connections as shown in the manual
of the electronic control unit and bearing in mind the
characteristics required by the general assembly drawing.
ADjusTmenT oF elecTricAl limiT swiTches
PUNTO is provided with opening and closing limit
switches, which control the start of the slow-down cycle
of the bar (with anti-clockwise opening as supplied by the
manufacturer, limit switch MS1 CLOSE, MS2 OPEN) While
the limit switches are not in use, the bar moves at normal
speed, as soon as they are employed the slow-down phase
of approach to the mechanical stop commences. Move
the bar to the desired position for the start of the closing
slow-down phase manually, and adjust the corresponding
cam CS until the limit switch is triggered. Move the bar to
the desired position for the start of the opening slow-down
phase manually, and adjust the corresponding cam CS
until the limit switches are triggered (figure 6).
Carry out an automatic operation and check the exact
position of the cams.
TesTing
Starting from the barrier closed position, carry out complete
OPEN and CLOSE cycles to check for correct positioning of
the limit switches and the function of the safety devices
installed. Reassemble the front door and the protection
guard “Cp”.
Instruct all personnel involved with operating the mechanism
about the commands, safety devices, emergency manoeuvre
and danger involved when operating the mechanism.
Fill in the technical file for the installation and fulfil any
obligations required by regulations in force.
Correct functioning of the PUNTO barrier is guaranteed only
and exclusively when equipped with DASPI safety devices
and only when equipped with an original command card.
emergency or mAnuAl mAnoeuVre
An emergency or manual manoeuvre is carried out during
the installation stage and only in the case of malfunction of
the mechanism or in the absence of electrical power.
ATTENTION: Do not release or put in automatic the motor
when it’s working
ATTENTION: For any reason whatsoever never carry an
emergency or manual manoeuvre if the barrier arm is not
assembled
ATTENTION: For any reason whatsoever never
disassemble
the barrier arm when it is in a horizontal position Disconnect
the power supply.
Insert the special “Ch” key in to the “Sb” lock and turn it in
an clockwise for 180° until the mechanism unlocks (picture
7) . Remove the pawl from the lock and insert the Allen key
CH1 in the hole until you reach the proper place (pic.8).
Turn the key CH1 anticlockwise until its end and lift the
boom up manually. To put the barrier in automatic, turn the
key CH1 clockwise until its end. Take the key CH1 off, re-fit
the pawl into the lock SB and close the protection lid TA.
Keep the “Ch1” key in a safe place that is known only to the
personnel who can operate the mechanism.
Reconnect the power supply making sure that no
personnel
are in the area where the barrier is moving.
