Jackshaft Model EGJ

Model EGJ is a damp environment operator. It features a high-cycle capacity, a compact design, requires no chaines or sprockets on sectional doors, handles tough environmental conditions and includes a dynamic brake.

Standard Features:

Motor: Continuous-duty, ETFC high starting torque motor with instant reverse and overload protection. Available in1/2 HP (375W); single phase. Capacitor start and three phase motors. Removable without affecting limit switch settings.

Drive Reduction: 45:1 sealed gear reducer with internal clutch system. "Through-Shaft" reducer design allows operator to be directly mounted onto the 1" torsion shaft of sectional doors, for an approximate door speed of 12"/second. Optional reduction shaft is required for use on rolling doors or sectional door to provide an approximate door speed of 8-9" per second.

Emergency Manual Operation: Model EGJ provides easy manual operation upon activation of the floor level disconnect.

Wiring Type: C2 wiring is standard, B2 is easily selected providing momentary contact to OPEN/CLOSE and STOP with open override. The operator is pre-wired to accept a sensing edge, photoelectric control, radio controls and most types of access control equipment.

Operator/Motor Control: Across-the-line type, size "0" contactor motor switching, mechanically interlocked (NEMA 4 enclosure).

Dynamic Brake: Assures stopping of door in damp environments.

Bearings: High-cycle sealed ball bearings on the gear reducer.

Friction Clutch: Adjustable friction clutch helps protect against damage to the door and operator should the door meet an obstruction.
