installation Operating Instructions for SC Series Powered Straightener The straightener that you just received is fully assembled and tested and ready to be put into position. CAUTION: Due to shipment vibration, it should be checked to be sure that all screws and bolts are secure and all electrical components are in place inside the cabinet, visually inspect the complete machine for physical damage due to shipment and handling.
Start up procedure Prior to applying power to the straightener, all the controls on the machine should be reviewed. A brief summary is listed below. Main Console And Controller The main control console with controls is mounted on the cabinet of the straightener. Located on the face of the console are five switches, one potentiometer, one push-button and one or two circuit breaker reset switches, which are explained below. 4.
dancer arm loop Dancer Arm Loop Height Adjustment Three different loop sensing arm operating positions are selected manually during set-up. By selecting the higher number, the zero point of the dancer arm is raised from its rest position to the angle shown (as indicated 0-2). The dancer arm will move from rest position to the angle selected before the straightener rolls begin to rotate.
standard straightener components Curve Up/Down Adjustment Entrance Guide Roll Block Some applications have dies that cannot accept anything but flat stock and other dies run better with the material curving up or down to miss the built in edge required in the die. Before this feature was added, operators would under straighten or over straighten the material to suit their needs but in doing so would severely change the material entering the die.
operation Once the straightener has been tested and all the functions work then it should be tested for what it was designed to do and that is to remove coil set. Retract all of the idler rolls and the exit pinch roll to a position so when the cover is closed the material is not being deformed. Open the cover of the straightener and position the edge guides for maximum width.

69100034 TAUT STOCK OUTPUT The 69100034—Proportional control board has a taut stock output. The output must be wired to a solid state relay as the max current draw is 20 MA. The solid state relay’s contact can then be incorporated into the electrical control circuitry. The output can be wired so that the relay is either on or off with the dancer arm down. When the dancer arm reaches the set point for taut stock, the relay switches state.
