FEATURES
The Model GT is a heavy industrial-duty trolley door opener, as manufactured by The Chamberlain Group, Inc. and is for use on standard lift sectional doors. It is rated for 25 cycles per hour constant high loading. In excess of 90 cycles/day.
Features:
- Trolley Type Door Opener
- Voltage/phase :
115/230V 1 phase
208/230/460V 3 phase
575V 3 phase
Class 2 Circuit with 40 VA transformer
- Horsepower: available in ½, ¾ and 1 HP.
- Additional headroom required: 4″
- Required depth: Door height + 48”
- 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 1-sec or 15-sec increments and permits timed automatic door closure after the door reaches the fully open position; requires monitored photosensors, either CPS-U, CPS-UN4, or a 4-wire edge, using the CPS-EI edge interface
- Thermal motor overload can be easily reset from the 3-button floor level control station
- Continuous-duty high-starting torque motor with instant reverse.
- Removable hinged electrical box cover.
- Quiet-gliding rail spacers.
- Single- or three-phase, capacitor start on single-phase.
- The motor is removable without affecting limit switch settings.
- All operators are factory preset to C2 wiring, providing momentary contact to open and stop, with constant contact to close. Monitored entrapment protection, using approved photosensors or sensing edges is optional, although recommended, when using C2, D1 or E2. All other wiring types, B2, T, TS, and FSTS, can be selected with the addition of an appropriate monitored entrapment protection device, either LiftMaster CPS-U / CPS-UN4 photosensors or a monitored 4-wire sensing edge (via a CPS-EI Edge Interface Card). Logic 4.0 operators can only accept UL-approved LiftMaster CPS-U, CPS-UN4 or CPS-EI monitored entrapment protection devices.
- 10:1 first stage using heavy-duty gears running in oil bath; cast iron housing; #41 chain second stage; #41 chain on a trolley.
- Sealed roller bearing in gear reducer.
- Heavy-duty solenoid-actuated brake.
- Adjustable friction clutch helps protect against major damage to door and operator should the door meet an obstruction.
- Spring-loaded disconnect for emergency manual operation.
- Motor overload protection.
- High-strength dual L-rail track with exclusive nylon quiet-gliding chain guides on rail spacers for quiet, smooth operation.
- 1.5-second delay-on-reverse circuit to prevent premature door and operator wear.
- The Timer-to-Close automatically closes the door – programmable in 1-second or 15-second increments.
- The mid-stop stops the door at programmable mid-stop during open travel.
- The Maximum Run Timer signals the door to reverse or stop if closing time exceeds maximum by more than 10 seconds.
- Maintenance alert system (5,000 to 10,000 cycles).
- UL and CSA listed.
- 2-year warranty.
