GLOSSARY 
 
AC:  Alternating Current.  An electric current or voltage that reverses direction at regular intervals. 
Alternate Action:  Ability to open and close a fully open gate by using the same open command. 
Arc:  The area that is swept by a swing gate from fully closed to fully open position. 
ATG:  Anti-tailgating refers to a method of immediately closing an opening gate behind a vehicle so 
that an unauthorized vehicle can not follow the authorized vehicle through the gate. 
DC:  Direct Current.  An electric current of constant value flowing in one direction only. 
Dynamic braking:  Stopping the gate by activating the forward and reverse windings of the gate 
operator motor in each half AC cycle. 
Fault:  An abnormal condition which causes the gate to stop to protect the gate and the user. 
Gate sensitivity:  The response of the gate operator to an exerting force to the gate. 
Gear Box:  A device that changes the speed and power of its driving force (motor). 
Inrush current:  Initial current drawn into an electrical device due to its capacitive or inductive nature. 
Interrupt Bar or Edge:  A switch which is installed at the edge of a gate to protect an object which is 
situated between the gate and the gate frame. 
LED:  Light Emitting Diode.  LEDs are indicators placed on the controller board which light up to 
indicate an action in the system. 
Limit switch:  A switch which its closure indicates the gate has reached its open or close limit, causing 
the gate to stop.  There are two limit switches, open and close. 
Limit cam:  An object which its excursion corresponds to the gate traveling distance and closes the 
limit switch at the open or close limit of the gate. 
Loop sensor:  A wire embedded in the ground for magnetically sensing large metallic objects (cars).  
  Exit or Open Loop:  activation opens the gate. 
  Interrupt  or Reverse or Reopen Loop:  activation reverses or stops the gate.  
  Shadow Loop:  activation prevents a fully open or closed gate from moving while a vehicle 
is inside the arc of a swing gate. 
Loop detector:  An electronic device that is activated by a loop sensor sensing a metallic object. 
Master/Slave:  A synchronized system containing a pair of gate operators. 
Maglock:  An electric magnet which is used to secure the closed gate.  
Power Fail Option:  A battery backup system which opens or closes the gate at power outage. 
Pulley:  A grooved wheel which transfers power via a belt. 
Reclose Timer:  An electronic timer which closes the fully open gate automatically. 
Retry:  A condition at which the stopped gate resumes its course automatically after the occurrence of 
 a Fault. 
RPM: Rotation Per Minute is a term to indicate the speed of an rotary object. 
Sprocket:  A toothed wheel which transfers power via a chain. 
Thermal overload:  A condition at which a heat producing device shuts off  automatically when it 
reaches a critical and damaging temperature level. 
Torque:  A force that causes rotation. 
Torque Limiter:  A clutch-like mechanism used to relieve excessive torque generated by the gate on 
the gate operator.
