  • Page 9 8. Test the operator for smooth control of the barrier arm. The arm should stop smoothly at each end of travel. If any adjustments are necessary, follow the HTG 320 adjustments document # HT 45. Also check the reverse delay timer by opening the gate as it is closing. The arm should stop then reverse in a smooth manner.

    HTG 320 Adjustments The HTG 320 gate operator is pre-adjusted at the factory to perform correctly with the barrier arm shipped. If the arm length, or weight is changed, it will be necessary to re-adjust the gate operator to perform correctly.

If the wire size used is too small, the voltage loss— especially during motor starting—will prevent the motor from attaining its rated horsepower.

    The slave operator will close when the master is signalled to close, unless the slave operator is not yet fully open. The control circuit of the HTG 320 is not compatible with the use of a stop button when the master and slave interconnection is used.
  • Page 22 Detector Installation Guide Detector Installation Guide Detector Installation Guide Detector Installation Guide Detector Installation Guide Loop Basics The vehicle detector passes a small current flow through the “loop” which then becomes an inductive coil. When a vehicle passes over a loop the detector senses the resultant drop in the inductance, and actuates it’s output relay.
  • Page 23 OR This Detector Logic Hy-Security Gate Operators recommends that vehicle detectors be used for free open and obstruction sensing logic only. The exception is in parking applications with our HTG320 operator where detectors may be also used to close the gate. In applications employing our swing , vertical lift, or sliding gate operators, closing logic cannot be used.
  • Page 26 HTG 320 Maintenance 1. Mechanical: The shaft bearings used in the HTG 320 are fully sealed. Very little lubrication is required. Even in heavy use, a single pump of grease once a year is adequate. The crank arm bearing does require lubrication at six month intervals.

  • Page 28 We recommend our UNIFLOW hydraulic oil. Part number H 004, as sold in one gallon units by Hy-Security Gate. Automatic transmission fluid may be used, although its performance will be sluggish in freezing weather, unless the operator is well heated. Other hydraulic oils, although technically compatible, tend to be too viscous for proper performance, even in modestly cool weather.

  • Page 29: Troubleshooting

    If the speed of a gate must be changed, contact your Hy-security distributor, or the factory. It is possible that extremely cold weather could affect the speed of the gate, due to the increase in load placed on the system by very thick hydraulic oil and stiff gate hardware.

  • Page 35: Limited Warranty

    (that are a design component of the gate operator) are warranted for one year from the date of shipment. Even though included as part of a Hy-Security gate operator, accessories carrying another manufacturers name plate, (unless a design component of the gate operator) shall carry only the warranty of the specific manufacturer.
