LiftMaster Model T - Trolley Arm Commercial Door Operator
Industrial-Duty Trolley Operator for Standard Lift Sectional Doors
T-style trolley commercial door operators are optimal for general industrial applications. Suspended from the ceiling, the operators are used on sectional overhead doors with standard lift.
T operators are directly attached to drive and control the door.Logic 5.0 Technology (L5)Connectivity
Safety and Security
- MyQ® Technology enables you to securely monitor and control your facility operator and lights with your smartphone, tablet or computer for greater peace of mind.
- Alerts can be received as email or pop-up (push) notifications on a mobile device, ensuring the status of your commercial door.
- MyQ Mobile App is a free download with no annual activation fee.
- Security+ 2.0™ safeguards your facility - with every click, a new code is sent to the commercial door operator so the door opens only for you.
- UL 325 requires all commercial door operators to be either constant pressure to close or be equipped with a primary external monitored entrapment protection device.
DUAL VOLTAGE CONNECTIONS
Increase flexibility by enabling the installer to select the required voltage, within phase, to meet job-site requirements.
Within phases, voltage is selectable at the time of installation with the placement of a connector.
- Single-Phase: 115V and 230V
- 3-Phase: 208V, 230V and 460V
- 575V is a discrete model without field-selectable voltage
Disconnects operator from door for manual lifting in an emergency.
CONTROL FUNCTION SELECTOR DIAL
Enables easy selection and programming of (7) wiring types, from constant pressure to close, to specialized Timer-to-Close functionality to meet end-user needs.
Conveniently and confidently closes the commercial door automatically after a predetermined amount of time has elapsed for added security and peace of mind.
CONTINUOUS-DUTY HIGH-STARTING TORQUE MOTOR
Performs in demanding industrial overhead door applications.
MOTOR REMOVABLE WITHOUT AFFECTING LIMIT SWITCH SETTINGS
Saves time and money for maintenance.
ADJUSTABLE FRICTION CLUTCH
Helps to protect door and operator from damage should the door meet an obstruction.
Enables partial opening of door to a preprogrammed position for energy savings, time savings and convenience.
MAXIMUM RUN TIMER
Reverses or stops door if closing time exceeds expected time-frame to limit damage to door and operator.
Prevents abrupt reversal of door, reducing wear on the door and operator system.
3-BUTTON CONTROL STATION WITHMAINTENANCE ALERT SYSTEM (MAS)
Provides open/close/stop functions and notification when routine maintenance is required.
SECURITY+ 2.0™ RADIO RECEIVER
Standard on-board with Logic 5.0 operators. Accepts up to (90) single-button or (30) 3-Button remote controls plus up to (30) wireless keypads or an unlimited number of DIP switch remotes.
Continuous-duty high-starting torque motor with instant reverse and overload protection. Available in 1/2, 3/4 and 1 HP; single- or three-phase. Capacitor start on single-phase. Removable without affecting limit switch settings
Operators are factory preset to C2 wiring, providing momentary contact to open and stop, with constant contact to close. Monitored entrapment protection, using approved photo sensors 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 appropriately monitored entrapment protection device (LiftMaster® CPS-U photo eyes, LiftMaster OES monitored sensing edge, or a monitored sensing edge supported by the CPS-EI, as examples). Logic 5.0 operators can only accept UL-Approved LiftMaster monitored entrapment protection devices.
