LOGIC 5.0 GEARHEAD HOIST COMMERCIAL DOOR OPERATORS EMPLOY LUBRICATED GEARS FOR HEAVY INDUSTRIAL, HIGH-CYCLE APPLICATIONS. These operators include a floor-level chain hoist for ease of manual operation in an emergency or power outage. CONNECTIVITY • MyQ Technology enables you to securely monitor and control your facility door 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. PERFORMANCE • Heavy-duty wormgear-in-oil gear reducer delivers performance for heavy industrial, high-cycle applications. • Floor-level chain hoist with electrical interlock provides easy disconnect and manual operation in an emergency. • Control function selector dial allows for easy selection and programming of (7) wiring types, from constant pressure to close to specialized Timer-to-Close functionality to meet end user needs. • Timer-to-Close conveniently and confidently closes the commercial door automatically after a predetermined amount of time has elapsed for added security and peace of mind. • Mid-stop enables partial opening of door to a preprogrammed position for energy savings, time savings and convenience. • 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. • Continuous-duty high-starting torque motor with instant reverse and overload protection. Capacitor start with single phase, removable without affecting limit switches. • Maximum run timer reverses or stops door if closing time exceeds expected time frame to limit damage to door and operator. • Delay-on-reverse circuit prevents abrupt reversal of door, reducing wear on the door and operator system. • 3-Button Control Station with Maintenance Alert System (MAS). • Drive reduction, 45:1 first stage using heavy-duty gears running in oil bath, cast iron housing. Special “all climate” synthetic gear oil for greater low temperature performance; #50 output sprocket chain. • Bearings: sealed roller bearings in gear reducer. • Brake: standard on all GH door operators. • Construction: NEMA 1 rated electrical box; heavy-duty 11-gauge steel frame with durable powder-coated finish; all reduction sprockets drilled and pinned to shafts. • Door speed: 8–9 in. per second (typical). SAFETY • Security+ 2.0 radio receiver is standard on-board with Logic 5.0 Operators and virtually eliminates radio frequency interference. Accepts up to (90) 1-button or (30) 3-button remote controls plus up to (30) wireless keypads or an unlimited number of DIP switch remote controls. • LiftMaster Commercial Door Operators comply with UL 325 standards. • LiftMaster offers a variety of entrapment protection devices for every commercial application. • Emergency disconnect, disconnects door operator from door for manual lifting in an emergency. • Warranty: 2 Years.
