INSTALLATioN
To operate a good installation of the gear motor BIG
FOOT follow these instructions:
Locate inside the property the correct point to install
BIG FOOT, usually near to the support column of the
gate.
Assemble the support plates "Pb" with the anchorage
pins and adjusting grubs (fig.
Build up a cement emplacement with sizes like fig.
3, foreseeing the passing of the protective coverings
"G" for the passing of the power supply and control
system cables.
Before the cement solidifying, install the bracket
"Pb" immersing the anchorage pins in the cement
and making sure that the bracket "Pb" is oriented
and perfectly on level (fig.
After that the cement will be perfectly solidified
install the gear motor BIG FOOT on the bracket
"Pb" and after removing the protection cover fix the
operator softly by supplied nuts "Vf"
Loose the screws "Vp" and make the operator
BIG FOOT run in the suitable holes to establish a
distance between the operator's pinion "P" and the
gate suitable to the type of rack "C" you want to
install. The tooth of the pinion must mesh with the
teeth of the rack for all its width, so fix the nuts "Vf"
(fig. 5).
Carry out an emergency or manual manoeuvre (see
the par. " Emergency or manual manoeuvre") and
put the gate in the maximum opening position.
Lean one end of the rack "C" on the pinion "P" , make
sure that it's horizontal and fix it by welding or by
the suitable screws "Vc" (fig.
slide the gate, checking that the rack don't force on
the pinion and that don't go away.
If the gate is crooked put between the gate and the
rack some thickness to assure the constant centring
between the rack and the pinion.
After fixing definitively the rack "C" loose slightly
the nuts "Vp" and adjust the play-gap between rack
and pinion (2 mm apron.) using the grubs "Gr" to
position correctly the operator
When everything has been done fix the nuts "If" and
the nuts "D1" and with a manual manoeuvre open
and close the gate to verify the correct alignment
(there have not been friction).
IMPortant
The duration of the rack and the pinion depend on
the right mesh engagement.
in view of the considerable weight of the gates we
recommend to use iron racks or steel racks with an
adequate thickness.
The gates must have mechanical stops "Fa"
in opening and closing to avoid its derailment.
The mechanical stops "Fa" must ensure an antic
rushing space between the mobile and fix part
of the gate, in conformity with the regulations in
force.

Put the gate in opening position and, according to
the gate weight, leave a space of 30-50 mm between
the gate and the mechanical stop "Fa"
the rack the limit switch support "S" by grubs "Gr1"
(fig. 9) in order to push the limit switch
Repeat the same operation on the other side, for the
closing limit switch support.
Make the circuitry like in the control panel manual
and install the obligatory safety devices.
Teach the people intended for the use of the
automation about the controls, safety devices,
emergency manoeuvre and dangerousness deriving
from the utilize of the automation.
Compile the technical booklet and fulfil the eventual
obligations deriving from the regulations in force.
We Guartntee the correct functioning of BiG FooT
versions only and exclusively if provided by dASpi
and only if combined with the original control
panel.
EmErGENcy or mANUAL mANoEUVrE
You have to do the emergency or manual manoeuvre
or during the installation, or only if the automation
does not work properly or if there is not power
supply.
cut off the power supply.
Open the plug on the handle "LS" cover and insert
the supplied key "CH" (fig.
Turn the key "CH" anticlockwise and take out the
handle of 90° towards you
manually.
In order to re-establish the normal functioning of
the automation, you have to put again the handle
"LS" in the original position and turn the key "CH"
clockwise, so take away the key and close the plug
on the handle.
Place the key "CH" in a safety place known
exclusively from the people intended for the use of
the automation.
Switch on the power supply, pay attention that
there's nobody where the gate is moving.
