4. INSTALLATION OF AUTOMATION
4.1. PRELIMINARY CHECKS
To ensure safety and an efficient automation, make sure the
following requirements are met:
•
The gate structure must be suitable for automation. In par-
ticular, wheel diameter must be in proportion to the weight
of the gate to be automated, an upper guide must be
supplied, and travel limit mechanical stops must be fitted to
prevent the gate from derailing.
•
The characteristics of the soil must ensure sufficient stability of
the foundation plinth.
•
There must be no pipes or electrical cables in the plinth
excavation area.
•
If the gearmotor is exposed to passing vehicles, if possible, fit
adequate guards to protect against accidental impact.
•
Check if an efficient earth plate is present for connection to
the gearmotor.
4.2. FOUNDATION PLATE MASONRY
1) Assemble the foundation plate as shown in Fig.4.
2) The foundation plate must be positioned as in Fig. 5 (right-
hand closure) or Fig. 6 (left-hand closure) to ensure the rack
and pinion mesh correctly.
3) Prepare a foundation plinth as in Fig.7 and enclose the
foundation plate in a wall providing one or more sheaths for
routing electric cables. Using a spirit level, check if the plate
is perfectly level. Allow the cement to set.
4) Lay the electrical cables for connection to the accessories
and power supply as in Fig.3.
To facilitate making connections, allow the cables to pro-
trude by about 45 cm from the hole (Fig.5-6 ref.
) of the
foundation plate.
