of the warning light as the gate leaf closes. The control
panel also accepts a wide range of product accessories
and reversing devices to allow you the maximum
flexibility in designing your gate system.
One feature of FAAC's slide gate operators is the
adjustable internal limit switch function. By setting the
operator to recognize the fully closed and fully opened
positions of the gate leaf's travel, you also enable the
operator to automatically brake the gate leaf before it
reaches the end of its travel in either direction, thus
causing less stress on your gate leaf.
Safety features on the 820 or 860 Operator include an
adjustable, oil-immersed clutch that is designed to help
provide anti-crush protection for both pedestrians and
property, as well as for the gate system itself. The
location of the clutch—on the input side of the gear
box—allows for sensitive control of sliding pressures.
WARNING
! The anti-crush clutch adjustment
should not be considered adequate protection
for pedestrians or property! Additional
reversing accessories, such as inductive loops,
photocells, or reversing edges, must be installed
for more complete pedestrian and property
safety.
With the clutch pressure properly adjusted, the 820
Operator or the 860 Operator with the Reverse on
Contact function (RC) automatically re-opens the gate if
an obstacle blocks the gate's closing. During opening,
an encountered obstacle causes the gate to stop its
motion.
WARNING
! When encountering an obstacle,
the 860 without the reverse on contact (RC)
function does not reverse during closing nor
does it stop on opening. To provide comparable
safety, you must use additional reversing
devices and you must adjust the operator’s
clutch with great care.
A Manual Release mechanism is also provided on both
the 820 and 860 (see Fig. 3). This lever operated
mechanism can be used to disengage the drive motor so
that you can open or close the gate leaf by hand. Such
manual operation of the gate is necessary during
installation and may be useful in power failures and
emergencies.
Also, on the chain-drive version of either the 820 or
860, a chain guard is provided to fit around the sprock-
ets and prevent foreign objects from being caught be-
tween the chain and sprocket. On the rack and pinion
version, a pinion guard is provided for comparable
safety.

Operating Logic
The 820 and 860 Operators provide a Manual Release
mechanism for manually operating the gate as well as
eight different operating logics (also see page 10).
Manual Release Mechanism
The Manual Release mechanism is a built-in emergency
release device of the 820/860 Operators (see Figure 3).
You disengage the operation of the operator by rotating
the Manual Release Lever in a clockwise direction.
Then you can move the gate by hand to open or close
the gate.
Operating the gate by hand is necessary during
installation and is useful during power failures and
other emergencies.
After such an emergency, you re-engage the drive of the
operator by rotating the Manual Release Lever
counterclockwise.
Caution:
After
you re-engage the drive with the
Manual Release Lever and
before
you signal the
operator, manually slide the gate leaf in either
direction until the gear is properly aligned and
locked. (You may hear it lock into position.)
This helps to protect the drive gear of your
operator.
