Motor Operators – CGEXTERNAL

MOTOR OPERATORS 
Motor operators offer the most efficient means of operation. They soon pay for themselves by conserving heat, by more efficient traffic flow, by savings in man- power. Further, for frequent or rapid use, remote controlled motor operators are mandatory.

Motor operators are integral power units engineered for long life and reliability. For each door or grille requirement, horsepower and gear reduction are designed conservatively.

STANDARD FEATURES 
U.L. CLASSIFIED OPERATOR 
INTERNAL PRE-WIRING TO TERMINAL BLOCK MOTOR -high starting torque ball bearing 


GEAR REDUCTION
 – Worm gear in oil bath (Model M) – chain sprocket gearing (Model H) 
CONTROLLER – Magnetic across-the-line reversing 
BRAKE – Solenoid actuated holding (Model M) -mechanical self-locking (Model H) 
CLUTCH – Adjustable friction type (Model H) 
EMERGENCY CHAIN OPERATOR – Independent of motor SAFETY INTERLOCK-for chain operation 
LIMIT SWITCH – Geared chair, driven 
OVERLOAD PROTECTION – NEMA 1 components CONTROL STATION – 3 button 
TRANSFORMER – 24 volt control circuit

OPERATOR MOUNTINGS (INTERIOR)+

VF mounting (vertical front-of-coil) is standard for Service doors and steel grilles up to approx. 270 sq. ft., and for all aluminum Grilles. VW mounting (vertical wall) is standard for larger steel doors and grilles, and for all Fire doors.

Optional mountings (HT, HS, HF) are available when in accord with good engineering practice.

+For doors mounted on exterior face of wall, with operators on exterior (i.e., types SEM & AEM), the VW mounting is applied
