Plug-in Horsepower Resistor® ­ (Must be obtained from your distributor as a separate part. ) The Plug-in Horsepower Resistor® is designed to match the control and motor without having to recalibrate the IR Comp. and CL see Section VI E, F on pages 9 and 10. ) Using the Plug-in Horsepower Resistor® chart, choose the closest value based on motor horsepower and/or armature current.

For motor horsepower not indicated, use the lower ohm value Plug-in Horsepower Resistor®. B. AC Line Fuse ­ The KBWMTM contains a 5Amp AC line fuse used to protect the control against catastrophic failure. If fuse blows, the control may be miswired, the motor is shorted or grounded, or the speed control module is defective. However, a shunt motor can also be controlled by wiring the shunt field directly to the 1/4" quick-disconnect terminals located on the main speed control module. CAUTION: Shunt-wound motors may be damaged if field remains connected without motor rotating for an extended period of time.

Fusing ­ As indicated in Section IIB, the KBWMTM contains a single AC line fuse on 208/230 VAC applications. In the USA and other countries where the 208/230 volt is derived from two (2) "hot" leads, both AC lines should be connected to a separate dual circuit breaker. AC Line Switch ­ The KBWMTM contains a double pole AC line switch which opens both legs of the AC line. OPERATION After wiring is complete, recheck connections to be sure they are correct. Also be sure correct armature fuse and Plug-in Horsepower Resistor® are installed. Internal lamp in power switch should be lighted indicating control is receiving AC line voltage. Note: if motor runs in opposite direction to what is required, turn power off and reverse armature leads. ! WARNING!If control is operated with cover off, be sure to wear safety glasses and use insulated tools if any adjustments are to be made. CL LED ­ A red light-emitting diode (LED) can be found on the speed control PC board. It lights when the current limit circuit activates, indicating an overload condition. [. . . ] Note: The minimum speed adjustment will affect the maximum speed setting. Therefore, it is necessary to readjust the maximum speed after the minimum speed. Maximum Speed Adjustment ­ Turn Speed Control Knob to full speed (full CW position). Note: Do not attempt to adjust the maximum speed above the rated motor RPM since unstable motor operation may occur. [. . . ]
