Logic 3.0 Technology (L3)
Added Value
Built-in 3-channel, 315MHz radio receiver accepts up to 23 Security+® or unlimited DIP switch remotes. 3-button remotes can be programmed for open/close/stop operation.
Maintenance Alert System™ establishes a routine maintenance schedule based on the number of cycles or calendar date. Includes self-diagnostic system that allows you to troubleshoot up to eight different error codes.
Timer-to-Close allows programming in 5-sec or 1-min increments. Commercial or industrial photo-eyes required.
Thermal motor overload can be easily reset from the 3-button floor level control station
Reliability & Programming Simplicity
Switchless motor eliminates stuck start switch and motor malfunctions on single-phase operators
All high-voltage connections have been removed from the board for safety and ease of service
Diagnostic LEDs speed installation and troubleshooting
Motor direction jumper lets you change motor direction by simply moving a jumper
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.

Standard Features
Motor: Continuous-duty high-starting torque motor with instant reverse and overload protection. Available in 1/3 and 1/2; single- or three-phase. Removable without affecting limit switch settings.

Door Lock Sensor: Adjustable door lock sensor can detect if the door lock is engaged and will stop the operator, eliminating jamming and damage to the door or operator.

Drive Reduction: First-stage heavy-duty 5L V-belt; second and third stages #48 chain; #50 drive chain.

Emergency Disconnect: Easy emergency manual operation using an electrically interlocked floor level disconnect and hoist mechanism.

Wiring Type: D1, C2 and B2 wiring types are all available. D1 wiring is standard and is pre-wired to accept a photoelectric control, sensing edge, radio controls and most types of access control devices. Failsafe wiring can be selected with the addition of a CPS-L, CPS-LN4 or failsafe edge and CPS3 card.

External Radio Control Terminal: Quick, convenient connections for retrofitting or adding radio controls on logic or mechanical operators.

Bearings: Industrial ball bearings on a 1" output shaft; heavy-duty oil-filled iron bearings on reduction shafts.

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: 2-button station for open/close functions is standard with D or D1 wiring. 3-button station is standard with B2 or C2 wiring.

Positive Locking Mechanical Brake System: Self-locking mechanical reduction system that functions as a holding brake.

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

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

2-Position Keylock (flush mount): Ideal for use with the DJ operator. Provides open/close operation with spring to center (Model 02-109).

Available Plug-in Options for Logic 3.0 (L3)
Auxiliary Contact: Used to operate security, warning, heating or other 5V to 240V devices. Features both normally open and closed contacts that actuate in conjunction with limit switches.

Warning Signal: Red/green light module provides safety warning prior to close (when using timer-to-close feature). Also supports audio warning devices and includes down mid-stop feature.

CPS3 Option: Enables the addition of a second set of photo-eyes or 2- or 4-wire, self-monitoring edge.
