|Heavy Industrial-Duty Trolley Operator|
LOGIC 4.0 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: 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: 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-U, CPS-UN4, or CPS-EI safety edge interface. The operator is pre-wired to accept a sensing device, 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: 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.
Primary Monitored Entrapment Protection:The presence of primary entrapment protection is required for all modes and features beyond basic constant-pressure-to-close performance. Primary entrapment protection devices are monitored continuously to insure safe operation of the door and limit door operator functionality should an obstruction be detected or in the event of device failure. LiftMaster Monitored Entrapment Protection devices, CPS-RPEN4, CPS-U, CPS-UN4 and CPS-EI, are designed to work in conjunction with LiftMaster commercial door operators to provide enhanced door safety and a broad range of modes and features to end users. Either monitored photo-sensor or monitored 4-wire sensing edge (in conjunction with the CPS-EI Edge Interface) protection may be selected, but one must be detected by the LiftMaster Logic 4.0 or Medium-Duty Logic circuit board in order to unlock full functionality.
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.
