These instructions are to be used as a reference only and are not intended to replace the detailed instructions provided herein. [. . . ] Read Safety Warning before attempting to use this control. Warning!To avoid erratic operation do not bundle AC Line and motor wires with potentiometer, voltage following, enable, inhibit or other signal wiring. Use shielded cables on all signal wiring over 12" (30 cm) ­ Do not ground shield. Wire control in accordance with National Electric Code requirements and other local codes that apply. The KBRG contains a single AC line fuse wired in series with terminal L1. Be sure to fuse each conductor which is not at ground potential (do not fuse neutral or grounded conductors). 12, for fuse information. ) Wire control in accordance with connection diagram (see fig. A separate AC line switch or contactor must be wired as a disconnect switch to control so that contacts open each ungrounded conductor.

Connect motor shunt field to terminals F+ and F- for 90VDC motors with 100VDC fields and 180VDC motors with 200VDC fields. For motors with half voltage fields, 90VDC motors with 50VDC fields and 180VDC motors with 100 VDC fields, connect field to terminals F+ and L1.

Ground ­ Be sure to ground (earth) the control via green screw located on chassis. Main Speed Potentiometer ­ The main speed potentiometer can be connected in several ways using terminals "10, " "11, " "12, " "13. " ( A 5K ohm potentiometer is supplied with control. Terminals "10, " "11, " "12" and "13" are not isolated from AC line. Unidirectional operation only ­ Connect potentiometer to terminals "10, " "12, " "13" for forward direction. (To operate in reverse direction, connect to "11, " "12, " "13. ") Bidirectional operation using reversing contacts ­ Connect to terminals "10, " "11, " "12, " "13" as per fig. Bidirectional operation with potentiometer ­ Connect potentiometer to terminals "10, " "11, " "12" as per fig. [. . . ] Run motor at approximately 30-50% of rated speed under no load and measure actual speed. Rotate IR Comp trimpot so that loaded speed is the same as the unloaded speed measured in the previous step. Control is now compensated so that minimal speed change will occur over a wide range of motor load. [Note: Too much IR Comp will cause unstable (oscillatory) operation. ] F. Maximum Speed (MAX) ­ The MAX trimpot is used to set the maximum output voltage of the control which, in turn, sets the maximum speed of the motor. [. . . ]
