SW490 Specifications

The SW490 electronic swing gate is engineered for heavy-duty applications where the gate is up to 22 feet long and weighs as much as 1000 pounds. To ensure excellent performance and long life, the SW490 comes with a high starting torque motor. The SW490 is recommended for duty cycles of 20 per hour.

The unit boasts a rugged design with the application of a harmonic gate arm, heavy-duty oil-in-bath wormgear reducer and a pre-galvanized steel weatherproof enclosure. Also, all of your preventative maintenance and service needs have been simplified by Sentex Systems' attention to detail. We have design the gate arm to disconnect easily, and a flip down entry panel makes the operator's electronics, gearbox, and motor easy to reach, easy to work on and easier on you.

Features: Full systems capability, Inherent obstruction sensing, Obstruction sensing alarm, Master/Slave operation, Gate movement warning, Remote device connections, Left/Right reversing switch, Delay on Reverse, Emergency one-button control station, On/Off Power, Timer to close, Access panel.

The SW490 is designed for heavy-duty commercial and industrial applications where the gate is up to 22 feet long weighing as much as 1000 pounds and handling up to 20 cycles per hour. This gate operator has been built to deliver years of dependable performance by utilizing a continuous duty high starting torque motor, with built-in overload protection and driven limit switches. This configuration reduces wear and tear on the operator as well as the gate.

What makes the SW490 the ideal choice is the engineered features designed into each unit by SENTEX SYSTEMS. The rugged design includes the use of a heavy-duty wormgear-in-oil-bath reducer, a pregalvanized steel weatherproof enclosure and a steel output drive shaft. All of your preventative maintenance and service needs have been simplified by SENTEX SYSTEMS' attention to detail. Sentex has incorporated a removable entry panel to make the operator's gearbox and motor easy to reach. Also, the control panel can easily be removed making servicing of the SW470 easy to work on and easier on you.

At SENTEX SYSTEMS, they understand the concerns associated with gate operation since gates include moving parts and powerful motors. For the concern of the installers, maintenance personnel and those utilizing gated installations, Sentex has implemented the required guidelines of UL325. The updated Underwriters Laboratory (UL) 325 listing covers many areas of the gate installation. Most of the guidelines are focused on obstruction sensing and how the system reacts to an obstructions. SENTEX SYSTEMS' SW490 has inherent obstruction sensing that utilizes a Hall Effect sensor to monitor the rotational speed of the drive during opening and closing. If an obstruction is sensed the operator will stop and then back up, by a pre-determined distance, releasing pressure on the obstruction. This is just one of the many ways that the SW470 provides you with maximum protection.

To complete a well-planned installation, demand a SENTEX SYSTEMS UL325 listed operator, and ou will have the entire SENTEX SYSTEMS team behind you, a team built on their quality and customer service.

Shipping: All gate operators are shipped by Motor Freight you must select the Motor Freight option when ordering gate operators. UPS does not ship gate operators

Full Systems Capability The SW490 can be used with a manual override switch installed at a guard station and/or a 3rd party access control system to permit visitor access. The open request from either systme will initiate the appropriate cycle.	Delay on Reverse When the gate has reached its maximum opening point, the SW490 motor will delay the return momentarily to prevent shocking the motor.
Automatic Shut Down This circuit will automatically shut off the operator. For example, it will prevent the motor from continuously running if the chain has broken.	Control Station A one button (Emergency Stop) control station is included preassembled, with the unit, for safety and manual stopping operations.
Inherent Obstruction Sensing A built-in Hall Effect sensor is used to monitor the rotational speed of the drive system. If this speed changes during opening or closing, the operator will stop and release pressure on the obstruction.	On/Off Switch An On/Off power switch is included to make installation and servicing easier.
External Obstruction Sensing In addition to the inherent obstruction sensing, the SW490 operators provide termianl connections for external devices such as photo eyes.	Timer to Close An adjustable timer (1-220 sec.) is used to close the gate after a pre-determined time ahs expired. A "defeat" jumper is also included in the event the feature is not required.
Obstruction Sensing Alarm If the operator senses two obstruction during a single cycle, a separate loud  audible alarm sounds to alert anyone in close proximity that assistance is required.	Removable Control Panel The control panel on the SW490 can be easily removed to provide for quick installation and maintenance.
Master/Slave Operation If there is a requirement for two separate gate operators to operate in unison at a single entrance, the SW490 can be configured as a master/slave and right/left operation to ensure consisten open and close cycle for both operators simultaneously. This configuration is made simple with the utilization of a two wire communication connection.

Gate Movement Warning For enhanced safety, a built-in warning alarm can sound three seconds before running and during the movement of the gate. This is a selectable item with the use of dip-switch settings.
Long Distance Control Wiring An external device, such as an exit request, may be hard wired up to 1000 feet from the operator to initate the appropriate cycle.
Limit Switches All driven limit switches are fully adjustable to add convenience to your installation and maintenance.
