3.5 Clutch Adjustment
This vehicular gate operator is equipped with an inherent adjustable clutch (Type C) that is used as the Primary entrapment
protection system. The clutch MUST slip upon sensing an obstruction during the open or close cycle which will cause the gate
to reverse direction. For this system to function correctly, the gate must be properly installed and work freely in both directions.
A good set of roller bearing hinges is essential for proper swing gate operation.
In addition to the mechanical slip clutch, this operator uses an inherent entrapment protection system (Type A) to further
reduce the possibility of injury should an entrapment occur. This Secondary entrapment protection system (Revering sensor) is
completely automatic and will be activated if the clutch fails to slip when an obstruction is sensed during the open or close
cycle. This feature requires no adjustment by the installer or end user.
3.6 Inherent Entrapment Protection System
Test the Clutch:
Obstruct the gate while it is in the OPENING cycle.
The clutch MUST slip with no more than 40 Lbs of
force, then the gate will reverse direction for a
quarter of a second and STOP. If the clutch does not
slip, it is too tight. Repeat step 4 and re-adjust the
clutch.
Note: After the gate has reversed and STOPPED, the
operator will be in a “Soft Shutdown”. Momentarily
jump across terminals 11 and 20 to continue the
opening cycle after the obstruction has been
cleared.
Obstruct the gate while it is in the CLOSING cycle.
The clutch MUST slip with no more than 40 Lbs of force, then the gate will REVERSE direction back to the open position.
If the clutch does not slip, it is too tight. Repeat step 4 and re-adjust the clutch.
Note: After the gate has reversed back to the open position, the operator will be in a “Soft Shutdown”. Momentarily jump
across terminals 11 and 20 to start the closing cycle again after the obstruction has been cleared.
1. Be sure AC power switch is turned OFF whenever adjustments to the clutch are being made. Loosen the
upper jamb nut to “un-lock” the lower jamb nut. Loosen the lower jamb nut.
2. Manually move the gate so that it is positioned approximately half way open.
3. Tighten the lower jamb nut finger tight then tighten it ONE turn with a wrench. Re-tighten the upper jamb nut.
4. Turn AC power switch ON and momentarily jump across terminals 11 and 20. When the gate begins to open,
determine if the clutch is slipping. If the clutch is slipping, turn AC power OFF and tighten the lower jamb nut
one more turn. This process may have to be repeated several times to get the clutch adjusted correctly.
Always start the gate from the half open position when adjusting the clutch.

Clutch Note: The ideal clutch adjustment will
allow the operator to move the gate through its
open and close travel cycle without slipping,
but will slip upon contact with an obstruction
with no more than 40 Lbs of force. This force
can be measured with a gate scale, DoorKing
P/N 2600-225.
CAUTION: Keep pedestrians and
vehicles clear of the gate while
adjusting and testing the clutch!
