Standard Features:
Motor:
Powerful 1/2 HP, single-phase motor with instant reverse and internal automatic reset thermal overload. Removable without affecting limit switch setting.
Auxiliary reversal system:
Designed to protect the door and door opener from damage; if a closing door strikes an obstruction, the Auxiliary Reversal System will detect the slip of the clutch and reverse the door to the full-open position. This system is not a substitute for a safety sensing device such as a photo cell or reversing edge.
Wiring type:
All openers are factory preset to C2 wiring, providing momentary contact to open and stop, with constant contact to close. Momentary contact to close (B2 wiring) can be easily set. The opener is pre-wired to accept a sensing device, photoelectric sensors, radio controls and most types of access control equipment.
Rail assembly:
High-strength dual L-rail track with exclusive nylon quiet-gliding chain guides on rail spacers for quiet, smooth operation. Includes quick-mount header bracket, which provides fast, swing-up installation.
Opener/motor control:
Dependable dual relay system (NEMA 1 enclosure).
Control circuit:
24V NEC Class 2.
Drive reduction:
First-stage heavy-duty 4L V-belt; second ans third stages #48 chain; output on trolley #48 chain.
Emergency disconnect:
Spring-loaded disconnect for emergency manual operation.
Push button station:
3-button station, for OPEN/CLOSE/STOP functions, is standard for all openers. Controls with 1, 2, and 3 buttons are available.
Construction:
NEMA 1 type electrical box, heavy-duty 11-gauge steel frame with baked-on powdercoat finish, all reduction sprockets drilled and pinned to shafts.
Bearings:
Heavy-duty oil-filled bearings.
External radio control terminal:
External terminals provide quick, convenient connections for
universal radio controls.
Friction clutch:
Adjustable friction clutch helps protect against damage to the door and opener should the door meet an obstruction. Works in conjunction with the Auxiliary Reversal System.
