5. Maintenance of Gate Systems

To keep your automated gate system performing
both safely and reliably it is important to ensure
that the components of that system are functioning
properly. At least monthly:
5.1 Disconnect the gate operator and manually
move the gate through its range of travel.
Note any squeaks from rollers or hinges or
areas of binding. The gate should travel
smoothly and quietly throughout its range.
If it does not, contact a gate professional to
correct the problem.
5.2 Reconnect the gate operator and perform the
following tests:
5.2.1 With the gate opening, block any photo
eyes and/or depress any safety edges used
to protect the open direction. The gate
should stop, or, stop and reverse.
5.2.2 With the gate closing, block any photo
eyes and/or depress any safety edges used
to protect the close direction. The gate
should stop, or, stop and reverse.
5.2.3 Using a suitable obstruction in the path of
the gate (a solid, immovable object), run the
gate in the open direction until it contacts
the obstruction. The gate should stop and
reverse.
5.2.4 Using a suitable obstruction in the path of
the gate (a solid, immovable object), run the
gate in the close direction until it contacts
the obstruction. The gate should stop, or,
stop and reverse.
