|Industrial-Duty Trolley Operator for Standard Lift Sectional Doors –|
Model T is an industrial-duty trolley operator for standard lift section doors. It features a low profile and industrial ball bearings on the output shaft.
LOGIC 4.O TECHNOLOGY (L4)
Reliability & Programming Simplicity
Available Plug-in Options for Logic 4.0 (L4)
TLS1CARD: Provides seven field-selectable modifications, including six door traffic control options. Combines with Logic 4.0’s standard Timer-to-Close feature to offer timed, sequenced activation of warning lights, sounders, and other devices (sold separately) that can be operated via dry contact closure.
CPS3 or CPS3-N4 Option: Enables the addition of a second set of photo-eyes.
Mechanical Reversing Contactor Circuit (M): (115V, 208/230V, 460V, 575V, 24V NEC Class 2 Circuit with 40VA transformer) Industrial linear contactor provides significantly longer control runs than conventional contactors.
Drive Reduction: First-stage heavy-duty 5L V-belt; second-stage #41 chain; output on trolley #48 chain on 1/3 and 1/2 HP; #41 chain on 3/4 and 1 HP.
Emergency Disconnect: Spring-loaded for emergency manual operation.
Wiring Type: All operators are factory preset to C2 wiring providing momentary contact to open and stop, with constant contact to close; D1 and E2 wiring are also available. Momentary contact to close (B2 wiring), T, TS, and FSTS wiring can be activated with the use of CPS-RPEN4, CPS-RPEN4, CPS-U, CPS-UN4, or CPS-EI safety edge interface. Operators are pre-wired to accept a sensing edge, photoelectric sensors, radio controls and most types of access control equipment.
External Radio Control Terminal: Quick, convenient connections for retrofitting or adding radio controls on logic or mechanical operators.
Bearings: Ball bearings on output shaft; heavy-duty, oil-filled bushings on reduction shafts.
Brake: Solenoid-actuated brake is standard on 3/4 and 1 HP units to prevent coasting of door. Optional on 1/3 and 1/2 HP units.
Friction Clutch: Adjustable, helps protect against major damage to door and operator should the door meet an obstruction.
Construction: NEMA 1 type electrical box, heavy-duty 11-gauge steel frame with durable powdercoat finish, all reduction sprockets drilled and pinned to shafts.
Push Button Station: 3-button station comes standard and has OPEN/CLOSE/STOP functionality.
Quick-Mount Header Bracket: For fast, swing-up mounting.
Rail Assembly: High-strength dual L-rail track with nylon quiet-gliding chain guides on rail spacers for quiet, smooth operation.
Warranty: 2-year warranty.
Ancillary Entrapment Protection: (optional) LiftMaster Retro-Reflective Commercial Protector System® photo sensors, 2-wire non-monitored sensing edges and pneumatic sensing edges are considered secondary entrapment protection and may be used to supplement primary entrapment protction or basic constant-pressure-to-close.
