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.
