MEDIUM-DUTY LOGIC TECHNOLOGY
UL325-2010 compliant Medium-Duty Logic programmable integrated circuit board
Built-in 3-channel, 315MHz radio receiver accepts up to 20 Chamberlain® Security+® or unlimited DIP switch remotes.
3-button remotes can be programmed for OPEN/CLOSE/STOP operation
Programmable C2 or B2 wiring options (B2 requires CPS-RPEN4, CPS-U, CPS-UN4, or CPS-EI)
Integrated Timer-to-Close (TTC) allows programming from 5 to 60 seconds in 5-second increments. Allows for timed automatic door closure after the door reaches the full open position (Requires monitored safety devices, with CPS-RPEN4, CPS-U, CPS-UN4, or CPS-EI)
Integrated 90-second maximum run timer
UL325-2010 Monitored Entrapment Capability
Monitored protection against transient overvoltage conditions
3-button control station included
Motor: Powerful 1/2 HP, 115V single-phase motor with instant reverse, capacitor start and overload protection. Removable without affecting limit switch settings.
Drive Reduction: First-stage heavy-duty 4L V-belt; second and third stages #48 chain.
Emergency Manual Operation: Easy emergency manual operation using a floor level disconnect or an electrically interlocked chain hoist mechanism.
Operator/Motor Control: Solid-state Medium-Duty Logic circuit board.
Radio Receiver: 315 MHz radio receiver is integral to the Medium-Duty Logic board. Accepts up to 20 Security+® remote controls and unlimited DIP switch remote controls.
Bushings: Heavy-duty oil-filled bushings.
Friction Clutch: Adjustable, 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 for OPEN/CLOSE functions is standard for all operators. Controls with 1, 2 and 3 buttons are available.
Warranty: 2-year warranty.
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.
