Warning!Before installing the SIMG onto the KBMG, the AC power must be disconnected. The following Installation and Wiring instructions are to be used as a supplement to the KBMG Installation and Operating Instructions Manual (Part No. Refer to the SIMG Installation and Operating Instructions Manual (Part No. A40269) for specific and external signal following connections. [. . . ] If no load is applied to the motor, the motor will rotate at a speed proportional to the torque setting as set by the main potentiometer (see fig. By using the ACCEL and DECEL trimpots, the application of torque can be made more gradual or less gradual as required by the application. A maximum torque can be established using the current selector jumper, J2, which can be further modified by using the FWD and REV CL trimpots. 5 ­ JUMPER J6 SETTING Regenerate to Stop (RTS) ­ Coast to Stop Regenerate to Stop This function operates in conjunction with the Enable circuit, which is used to start and stop the control electronically. If the circuit connecting terminals "EN" and "COM" on terminal block TB1 are opened, the control will cause the motor to stop. When jumper J6 is in the factory position (RTS), the motor will regenerate to a stop. If J6 is changed to the coast to stop (CTS) position, the motor will coast to a stop when the "EN" - "COM" circuit is opened. Note: Control will not run unless a jumper or closed contact is connected between the "EN" and "COM" terminals. 12 FIG. 6 ­ SPEED CONTROL MODE 13 FIG. 7 ­ TORQUE CONTROL MODE (Linear) 14 IV. Mount the KBMG-212D on a flat surface in an atmosphere free of moisture, metal chips, and corrosion. A 5K ohm remote speed potentiometer is provided with each control. Install potentiometer using hardware provided. Be sure to install insulating disk between potentiometer and inside of front panel. Enclosure ­ When mounting the KBMG-212D in an enclosure, it must be large enough to allow the proper heat dissipation. A 12"12"12" enclosure is suitable when the control is not mounted on an auxiliary heatsink. A 12"12"24" enclosure is appropriate at full rating (11. 0 amps) when the control is mounted on an auxiliary heatsink KB P/N 9861. Read Safety Warning before attempting to use this 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.

[. . . ] 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: Excessive IR Comp will cause unstable (oscillatory) operation. [. . . ]
