3.4 Inherent Entrapment Sensing Adjustment
3.3 Limit Sensing System Adjustment
This vehicular gate operator is equipped with an inherent adjustable reversing sensor (Type A)
that is used as the primary entrapment sensing system. The gate will reverse upon sensing an
obstruction in either the opening or closing gate cycle and will cause the gate operator to
reverse direction should an obstruction be encountered. For the reverse system to function
correctly, THE HUB MUST NOT SLIP when the gate encounters an obstruction. 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.
Loosen the set screws to adjust the
limit sensors to the open and closed
positions of the operator arm.

Magnetic sensor activator
must be directly above the
limit sensors to activate
them.
The hub must not slip during operation.
Tighten bolt to stop any slipping.
The ideal adjustment will allow the operator to move the gate through its entire travel cycle without reversing, but will reverse
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.
In addition to the inherent reversing
sensor system, this operator has
provisions for the connection of a
non-contact (type B1) secondary
entrapment protection device.
A secondary entrapment protection
device must be installed with this
operator.
