Heavy Industrial-Duty Trolley Operator for Standard Lift Sectional Doors
Model GT is a heavy industrial-duty trolley operator for standard lift sectional doors. It features a continuous-duty high-starting torque motor, quiet-gliding rail spacers, a quick-mount swivel header bracket and a removable hinged electrical box cover.

Added Value

Built-in 3-channel, 315MHz radio receiver accepts up to 23 Security+® or unlimited DIP switch remotes. 3-button remotes can be programmed for open/close/stop operation.
Maintenance Alert System™ establishes a routine maintenance schedule based on the number of cycles or calendar date. Includes self-diagnostic system that allows you to troubleshoot up to eight different error codes.
Timer-to-Close allows programming in 5-sec or 1-min increments. Commercial or industrial photo-eyes required.
Thermal motor overload can be easily reset from the 3-button floor level control station
Reliability & Programming Simplicity

Switchless motor eliminates stuck start switch and motor malfunctions on single-phase operators
All high-voltage connections have been removed from the board for safety and ease of service
Diagnostic LEDs speed installation and troubleshooting
Motor direction jumper lets you change motor direction by simply moving a jumper
Available Plug-in Options for Logic 3.0 (L3)
Auxiliary Contact: Used to operate security, warning, heating or other 5V to 240V devices. Features both normally open and closed contacts that actuate in conjunction with limit switches.

Warning Signal: Red/green light module provides safety warning prior to close (when using timer-to-close feature). Also supports audio warning devices and includes down mid-stop feature.

CPS3 Option: Enables the addition of a second set of photo-eyes or 2- or 4-wire, self-monitoring edge.

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.

Motor: Continuous-duty high-starting torque motor with instant reverse and overload protection. Available in 1/2, 3/4, 1 and 1 1/2 HP; single- or three-phase. Removable without affecting limit switch settings.

Drive Reduction: 10:1 first stage using heavy-duty gears running in oil bath; cast iron housing; #41 chain second stage; #41 chain on trolley.

Emergency Disconnect: Spring-loaded for emergency manual operation.

Wiring Type: B2, C2, D1 and E2 wiring types are standard and easily set using a selector dial on the Logic 3.0 Control Board (L3). T and TS wiring can be activated with use of a CPS-L or CPS-LN4. Reversing Contactor Units (M) have C2 wiring standard and B2 available by simply moving a jumper wire. Operators are pre-wired to accept a sensing edge, photoelectric sensors, radio controls and most types of access control equipment. Failsafe wiring can be selected with use of a CPS-L, CPS-LN4 or failsafe edge and CPS3 card.

External Radio Control Terminal: Quick, convenient connections for retrofitting or adding radio controls on logic or mechanical operators.

Bearings: Sealed roller bearings in gear reducer. Flange-mount industrial ball bearings on drive shaft.

Brake: Solenoid-actuated brake is standard.

Clutch: Heavy duty torque limiter 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.

CPS® Commercial Protector System®: (recommended) A “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 door operator to stop or reverse as desired. An electric or pneumatic sensing device can be added to bottom edge of door.
