MODEL EGJ – EGJ PDF File

Damp Environment Operator
Standard Features: Motor: Continuous-duty, ETFC high starting torque motor with instant reverse and overload protection. Available in 1/2 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″ per second. Optional reduction shaft is required for use on rolling doors or sectional door to provide an approximate door speed of 8 to 9 inches 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” contractor motor switching, mechanically interlocked (NEMA 4 enclosure).

Dynamic Brake: Assures stopping of door in wet 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.

Pushbutton Station: Three button station for OPEN/CLOSE and STOP functions is incorporated into the wall mounted NEMA 4 electrical enclosure. Additional NEMA 4 controls with one, two or three buttons are available.

Construction: NEMA 4 type electrical box and TEFC motor.

Control Circuit: 24V NEC Class 2.

Control Accessories and OptionsOperator Cover: For wall-mounted operators. Recommended for damp environments where direct spray is present (1A3982).

CPS-N4™ NEMA 4 Commercial Protector System: (Recommended) A reliable “non-contact” photo safety sensor designed to sense an obstruction and signal the door operator to reverse to open.

Sensing Edge: (Recommended) Designed to sense an obstruction and signal the door to open. Either an electric or pneumatic edge system can be used.

NEMA 4 Control Station: A die cast metal NEMA 4/12 outdoor surface mount 3 button control station will withstand your wet environment. (02403)

Warranty: 2-year warranty.

The Door Lock Sensing Circuit: The Model LGJ includes a speed sensor in the electrical enclosure and a sensing circuit which sends a signal to stop the motor if the door jams, such as would be caused by failure to release the lockbar of a rolling grille before starting the operator. In addition to stopping the motor, if the door or grille is in fully closed position, it will drive the motor in the opposite direction for approximately 1 inch of door travel. This releases the pressure on the lockbar thus allowing the lock to be easily opened.This modification also contains logic that can be used to sense obstruction to door movement in mid-travel. The circuit is programmed to stop a door that is obstructed while opening and reverse a door that is obstructed closing.

Warning: THIS FEATURE SHOULD NOT BE USED IN LIEU OF A BOTTOM BAR SENSING EDGE OR OTHER ENTRAPMENT PROTECTION DEVICE. THE CIRCUIT FUNCTIONS ONLY WHEN THE OPERATOR IS STALLED; THEREFORE, IN THE CLOSING MODE, A ROLLING DOOR OR GRILLE WILL “BUNCH UP” BEFORE THE CIRCUIT FUNCTIONS.
