Adjust the Clutch of the
Operator
WARNING!
Turn the main power off before
you make any electrical connections, set any
switches inside the operator, or adjust the
clutch.
Adjusting the clutch of the operator adjusts the pressure
that the operator applies to the gate leaf. To adjust the
clutch, you must first remove the plastic cap from the
drive shaft (see Figure 17). Then, adjust the clutch with
a 6-mm Allen wrench while holding the motor fan
assembly to prevent the motor shaft from turning while
you make the adjustment.
Turning the clutch screw clockwise tightens the clutch
and results in more pressure being applied by the
operator. Turning the clutch screw counterclockwise
loosens the clutch and results in less pressure. Adjust
the clutch so that the gate leaf moves with the least
amount of pressure necessary to move it.
Faac International, Inc., recommends that the gate
should stop all movement if it enounters a force aof
about 33 lb. (15 kg).
Once you have adjusted the clutch, do
not
replace the
cap over the drive shaft.
Caution
: Adjust the clutch of an 860 Operator
with the optional RC (reverse on contact)
function very carefully. Realize that the RC
function may or may not be available on your
operator: Gates requiring excessive and uneven
pulling force can cause the RC function to not
work. If after adjusting the clutch of your
operator the RC function still does not work,
call our technical department for assistance.
WARNING
! The 860 Operator without RC
does not have a reverse on contact function.
This makes the adjustment of the clutch critical:
The gate leaf should move with the least
amount of pressure necessary. In addition,
FAAC strongly recommends you install
reversing devices (see Figure 16).
