5 INSTALLATION OF AUTOMATED SYSTEM
5.1 PRELIMINARY CHECKS
To ensure safety and an efficiently operating automated system, make sure the following conditions are observed:
• The gate structure must be suitable for automation. The following are necessary in particular: wheel diameter must be in
proportion to the weight of the gate to be automated, an upper guide must be provided, plus mechanical limit switches to
prevent the gate derailing.
• The gate slide track must be linear and horizontal.
• Manual movement of the gate must be easy throughout its travel.
• The soil must permit sufficient stability for the foundation plinth.
• There must be no pipes or electric cables in the plinth excavation area.
• If the gearmotor is exposed to passing vehicles, install, if possible, adequate means of protection against accidental im-
pact.
• Check if an efficient earthing is available for connection to the gearmotor.
If the elements checked do not meet the above requirements, arrange to ensure their compliance.
