Installation and Maintenance Manual

Install an Automatic Swing Gate Operator Only When:
 The gate moves freely in both directions. Never over-tighten a clutch or pressure relief
valve to compensate for a stiff moving gate.
 The operator will not swing the gate into a public access area.
 The operator will be properly electrically grounded and the intended supply voltage matches
the voltage label on the operator.
 The operator controls will be located in a clear line-of-sight to the gate. Radio controls and
other remote access controls must be connected only to the Remote Open input.
 The required external entrapment sensors will be installed. Be certain to carefully review the
instructions for placement, installation and adjustment of these external entrapment sensors.
External entrapment sensors must function to reverse the movement of the gate in both the
opening and closing directions. If edge (contact) sensors are used, they are to be located
on the inside and outside leading edge of the swing gate and along the bottom edge of a
swing gate that is greater than 6‖ above the ground. If photo eyes or other non-contact
sensors are used, they are to be mounted in locations most likely to guard against
entrapment. A combination of contact and non-contact sensors may be used, but all must be
recognized components under the UL 325 standard.
 If the Entrapment protection is provided by a continuous pressure actuation control, a
placard must be installed next to the control station stating ―WARNING‖ – ―Moving Gate has
the Potential of Inflicting Injury or Death -
Do Not Start Gate Unless Path is Clear.‖
Additionally, no other activation device shall be connected and an automatic closing device
of any kind shall not be used.
 The automatic operator is labeled as appropriate for both the type and UL usage class of
the gate.
