Motor: Continuous-duty high-starting torque motor with instant reverse and overload protection. Available in 1/2 single phase capacitor start motors. Removable without affecting limit switch settings. Drive Reduction: First-stage heavy-duty 4L V-belt; second and third stages #41 chain; output on trolley #48 chain. 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. T and TS wiring can be activated with use of the CPS-L or CPS-LN4. Failsafe wiring can be selected with the addition of a CPS-L, CPS-LN4 or failsafe edge and CPS3 card. The operator is pre-wired to accept a sensing device, photoelectric sensors, radio controls and most types of access control equipment. Maximum Run Timer: Standard feature that protects against damage to the door and operator. Any time a closing door takes 10 seconds more than its programmed standard cycle time, the door will stop. Programmable Mid-Stop: Allows the door to sop at mid-point during open travel. Delay-on-Reverse Circuit: A one-second delay-on-reverse circuit to prevent premature door and operator wear. Low-Profile Design: Low-profile design can be ceiling-mounted for low headroom applications. External Radio Control Terminal: Quick, convenient connections for retrofitting or adding radio controls on logic or mechanical operators. Bearings: Industrial ball bearings on the output shaft; heavy-duty, oil-filled 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: 3-button station comes standard and has open/close/stop functionality. Rail Assembly: High-strength dual L-rail track and quick-mount header bracket which provides fast, swing-up installation. |
