Added Value

  • 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 B2 or C2 wiring options
  • Integrated Timer-to-Close (TTC) allows programming from 5 to 60 seconds (CPS®-L or CPS®-LN4 photo-eyes required)
  • Integrated 90-second maximum run timer
  • Monitored entrapment capability

  • 3-button control station included

STANDARD FEATURES
Motor: Powerful 1/2 HP, single phase motor with instant reverse and internal automatic reset thermal overload. Removable without affecting limit switch settings.

Auxiliary Reversal System: Designed to protect the door and door operator from damage; if a closing door strikes an obstruction, the Auxiliary Reversal System will detect the slip of the clutch and reverse the door to the full open position. This system is not a substitute for a safety sensing device such as a photo cell or reversing edge.

Wiring Type: All operators are factory preset to C2 wiring providing momentary contact to open and stop, with constant contact to close. Momentary contact to close (B2 wiring) can be easily set. The operator is pre-wired to accept a sensing device, photoelectric control, radio controls and most types of access control equipment.

Rail Assembly: High strength dual L-rail track with exclusive nylon quiet gliding chain guides on rail spacers for quiet, smooth operation. Includes quick-mount header bracket which provides fast, swing-up installation.

Operator/Motor Control: Dependable dual relay system (NEMA 1 enclosure).

Control Circuit: 24V NEC Class 2.

Drive Reduction: First stage heavy-duty 4L V-belt; second and third stages #48 chain; output on trolley #48 chain.

Emergency Disconnect: Spring-loaded disconnect for emergency manual operation.

Push Button Station: 3-button station for OPEN/CLOSE/STOP functions is standard for all operators. Controls with 1, 2 and 3 buttons are available.

Construction: NEMA 1 type electrical box, heavy-duty 11-gauge steel frame with baked-on powder coat finish, all reduction sprockets drilled and pinned to shafts.

Bearings: Heavy-duty, oil filled bearings.

External Radio Control Terminal: External terminals provide quick, convenient connections for universal radio controls.

Friction Clutch: Adjustable friction clutch helps protect against damage to the garage door and operator should the door meet an obstruction. Works in conjunction with the Auxiliary Reversal System.

Warranty: 2-year warranty.

CONTROL ACCESSORIES AND OPTIONS
Solenoid Brake: Solenoid actuated brake prevents coasting. Order operator BMT. Standard on 3/4 HP and higher.

Auto-Reconnect Trolley Assembly: Spring-loaded trolley features nylon inserts for quiet operation and auto-reconnect feature eliminating the need to manually reattach the door arm to the trolley after emergency disconnect.

Sensing Edge: (recommended) Designed to sense an obstruction and signal garage door operator to stop or reverse as desired. Either an electric or pneumatic sensing device can be added to bottom edge of the garage door.

Radio Control: Universal transmitters and receivers are available to signal the operator to open and/or close.

Key Switch: Designed to restrict operation of garage door to authorized personnel only. Various types available.

Interlock Switch: Prevents accidental operation of the garage door by interrupting the control circuit.

CPS® Commercial Protector System®: (recommended) A “non-contact” photo safety sensor designed to sense an obstruction and signal the garage door operator to reverse to open.

  • Safety of a non-contact infrared reversing sensor
  • Fast and easy-to-install
  • Patented electrical interface monitors system status at all times
  • LED indicators for quick alignment
