THE IMPORTANT SAFEGUARDS AND

INSTRUCTIONS IN THIS MANUAL CANNOT COVER ALL POSSIBLE CONDITIONS AND SITUATIONS WHICH MAY OCCUR DURING ITS USE. IT MUST BE UNDERSTOOD THAT COMMON SENSE AND CAUTION MUST BE EXERCISED BY THE PERSON(S) INSTALLING, MAINTAINING AND OPERATING THE EQUIPMENT DESCRIBED HEREIN.

-Indoor Use Only.

-Up to 12 foot high doors with a maximum weight of 400 pounds.

-Use with Safe Finish™ Photosystem (light beam across the door opening) or foam/pneumatic reversing edge door components - REQUIRED where the push button is out of sight of the door or any other automatic, remote or manual control is used to activate the door.

STANDARD FEATURES:

Sensing System: A built-in sensing system detects obstructions during door operation. If in the downward (close) travel mode, the Opener will sense an obstruction and reverse the direction of the door. In the open mode, the Opener will stop. Since all doors are different, the Sensing System has independent adjustments for customizing the level of force required for the normal opening and closing of specified doors. ( Page 16)

Close Limit Switch: In winter months it's common for small pieces of ice or packed snow to be trapped under the door. Ground swelling can also effect the close limit setting of the Opener. The LT 50 Close Limit Switch overrides the Sensing System during the last one inch of closing travel and prevents the door from reversing if it encounters an obstruction at this point.

PRODUCT FEATURES

Alternating Action Operation: The mechanical wall pushbutton functions in an Open/Stop/Close/Stop mode in normal operation. (Page 18)

Manual Release: A pull cord allows separation of the drive mechanism and manual operation of the door when desired, as in the event of a power failure. (Page 19)

Automatic Reconnection: Once power is restored, or automatic operation of the door is again desired, initiating operation in the normal manner (Push Button, Radio Control, etc.) will effect automatic reconnection of the Manual Release Mechanism. (Page 19)

Connections For Continuously Monitored Auxiliary Entrapment Protection Devices: The LT 50 Safe Finish™ Photosystem (light beam across the door opening) can be easily connected to the Opener. Control circuitry monitors the device continuously for proper operation. (Page 11) Consult the factory for compatibility of other auxiliary entrapment protection devices.

Momentary Contact To Close: The standard close operation mode is momentary contact of the mechanical Push Button, and a portable Radio Transmitter can be used to close the door (PageZ18). The internal Sensing System (described earlier) detects obstructions in the door’s path.

Constant Contact To Close: For utmost safety, after installation of a Safe Finish™ Photosystem, the standard operation mode can be configured to require constant contact on the mechanical Push Button to close the door if the photosystem fails or if there is a break or short in the wiring. In this mode of operation, a Radio Transmitter cannot be used to close the door. (Page 18)

Safe Finish™ Photosystem: An invisible infrared beam of light guards the door opening and reverses a downward moving door if the beam is broken by a stationary or moving object. The LT 50 motor control circuitry can be configured to constantly monitor the Safe Finish Photosystem for proper operation.

OPTIONAL FEATURES:

Digital Radio Controls: The LT 50 Opener covered in this Manual can be fitted with optional Radio Controls. Up to 19,683 private codes can be easily selected without use of tools. (PageZ15)

Deluxe Wall Push Button: A feature-packed accessory unit, the Deluxe Wall Station allows access to all of the Opener's functions. Open/Close button permits full control of the door’s operation. The Opener's built-in light can be turned on or off independent of door operation. A Security Switch allows the Opener to be deactivated for extended periods of time. (Page 19)

Keyless Entry System: A tamper resistant outdoor keypad, the optional Keyless Entry System permits entry to the garage without use of key or radio transmitter. Easily programmable, it accommodates four separate access codes of 4 digits. Lighted Buttons enhance nighttime use.
