4 INSTALLATION
4.1 PRELIMINARY CHECKS
Before starting the installation work, check the condition of the product
components, the suitability of the chosen gate opener model and the
suitability of the intended installation environment:
• Ensure that all material used is in perfect condition and fit for purpose.
• Make sure that the mechanical structure of the gate is suitable for
automation. This product cannot be used to automate a gate unless the
gate is already in good working order and safe; furthermore, it cannot
remedy defects caused by incorrect installation or lack of maintenance
of the gate.
• Check that the operating conditions of the devices are compatible with
the stated operating limits.
• Move the gate leaves manually in both directions to ensure the force
required is constant throughout the full range of movement.
• Move the gate leaves manually to any position then release them to
check that they remain stationary.
• Check that the area in which the operator is to be mounted is compatible
with the size of the unit and make sure there is sufficient clearance for
the full movement of the arm.
• Ensure that there is sufficient space around the operator to perform the
manual release procedure.
• Ensure that the surfaces on which the devices are to be mounted are
solid and able to provide a secure anchorage.
• Ensure that all devices to be installed are in a protected location such
that minimizes the risk of accidental impact.
4.2 OPERATING LIMITS
Before starting the installation work make sure the operator is correctly sized
in relation to the dimensions and length of the gate leaves and within the
limits of the values given in the chapter “Product technical specifications”.
4.3 PREPARATORY WORK FOR INSTALLATION
With reference to FIG. 1A e a FIG. 1B, choose the approximate position
in which each component of the system is to be installed and choose the
most appropriate connection layout. List of components required:
• Electromechanical
operators.
• Pair of photocells.
• Pair of opening limit stops and closing stop.
• Posts for photocells.
• Flashing
light.
• Key selector switch or digital keypad.
• Vertical electric lock (recommended for gate leaves of more than 3 m).
• Control
unit.
4.4 INSTALLING THE RAM OPERATOR
4.4.1 INSTALLATION
Perform the manual release as described in heading 4.4.3
• Choose the position for the gate opener in correspondence with a
sturdy cross member on the gate.
• Temporarily secure the rear plate to the pillar, which must be at least 100
mm in width (FIG. 2).
• With the gate fully closed, fix the front plate to the gate leaf (FIG. 3).
• Couple the operator to the rear bracket using the supplied nut and bolt
(FIG. 4). The operator cannot be installed with the cover upward.
• Fix the rod to the front plate with the supplied nut and bolt (FIG. 4).
4.4.2 INSTALLATION OF LIMIT STOPS AND SWITCHES
The RAM operator is not equipped with electronic limit switches and it is
therefore essential to ensure that the gate to be automated is equipped with
mechanical opening and closing limit stops.
4.4.3 OPERATOR MANUAL RELEASE
Perform the manual release procedure when the gate is to be opened
manually. Activation of the release system may result in uncontrolled
movements of the gate in the presence of imbalance or mechanical faults.
To release the operator, proceed as follows:
• Open the plastic hatch and insert the release handle (FIG. 5).
• Turn the handle clockwise (FIG. 6).
• This action serves to disengage the gear thereby allowing the gate to be
opened manually (FIG. 7).
• To resume automatic control of the gate, return the key to its initial
position (FIG.8)
• Remove the release handle and stow it in a safe place (FIG. 9).
