CONTROL STATION WIRING AND INSTALLATION CONTROL WIRING CONNECTIONS 1. Connect control wires to the P1 terminal block located on the logic board as shown. 2. Connect conduit with all control wires through the conduit hole in the electrical box enclosure marked with the label shown below. CONTROL WIRING USE COPPER WIRE ONLY 40-10032B WARNING To prevent possible SEVERE INJURY or DEATH, install reversing sensors whenC: AUTION • The radio is used. • The 3-button control station is out of sight of the door. • Or ANY other control (automatic or manual) is used. Reversing devices are recommended for ALL installations. 3. Apply power to the operator. Press OPEN push button and observe direction of door travel and then Press the STOP button. If door did not move in the correct direction, check for improper wiring at the control station or between operator and control station. NOTE: In "Diag" mode the 3-button control station can be tested to verify correct wiring of Open, Close and Stop buttons without moving the door. If the door moves in the wrong direction and or the limits move in the wrong direction, simply move the motor direction jumper located on the logic board from the factory default setting (STD) to the (REV) pins. This will change the motor rotation as well as the functional position of the OPEN and CLOSE limit switch's. Then relocate the safety limit switch (SLS) only to the opposite side with the new functional close limit location. Orient the arm (lever) of the limit switch away from the center. NOTE: The motor direction change is not available on the DJ and DH models. EXTERNAL RADIO WIRING CONNECTIONS On all models a radio terminal bracket marked R1 R2 R3 is located on the outside of the electrical enclosure. In B2 mode the operator will then open a fully closed door, close a fully open door, stop an opening door, and reverse a closing door from the radio remote. In TS control wiring the operator will only open the door or reset the timer to close. However, for additional door control from a 3-button remote, a commercial three-channel radio receiver (with connections for OPEN/CLOSE/STOP) is recommended. NOTE: If an external radio receiver is being used in place of the built-in receiver, remove or disconnect the coaxial cable from the logic board.
