Detailed instructions for use are in the User's Guide.
[. . . ] Install the correct Plug-in Horsepower Resistor® according to motor current and/or horsepower. Note: Disregard the horsepower rating marked on the Plug-in Horsepower Resistor® since they are marked for SCR controls. Recheck connections: AC line to L1 and L2; armature to A+ and A- (use F+ and F- for shunt motor field connections only. ) Note: If motor runs in improper direction, interchange armature leads. Nominal factory trimpot settings are as follows: (Expressed in % of full CW rotation).

ii. [. . . ] For applications that require superior performance, tachometer feedback is also provided. The KBWD contains (I x t) overload protection which will shut the control down if the motor is overloaded for a predetermined time. Diagnostic LEDs for "Power On" and "Overload" (CL) indication are also provided. It greatly reduces conducted interference which could affect sensitive equipment. The control contains barrier terminals as standard; however, quick disconnect terminals can be provided as an option. A potentiometer (5K), isolated analog signal (0-10 VDC), or PWM microprocessor output can be used to vary the output of the control.

*Based on motor having linear IR Comp characteristics.
A Plug-in Horsepower Resistor must be installed to match the control to the motor horsepower and armature current. CAUTION: Be sure Plug-in Horsepower Resistor® is inserted completely into mating socket.

The Plug-in Horsepower Resistor® will match the motor characteristics to the control without having to calibrate the current limit (CL) and IR Compensation (IR) for most applications. TABLE 2 PLUG-IN HORSEPOWER RESISTOR® CHART

1. To "Stop" the control, terminals I1 & I2 must be shorted via a contact. Read Safety Warning on page 1 before attempting to operate the control or severe injury or electrocution can result. After the control has been set up properly and the wiring has been completed, the start-up procedure can begin. If AC power has been properly connected to the control, the "ON" LED indicator will illuminate. Before starting, be sure the main potentiometer is in the minimum position. To start the control, the potentiometer knob should be rotated clockwise; the motor should begin to rotate. Note: If the motor rotates in the incorrect direction, it will be necessary to disconnect the main AC power and reverse the armature wires. TRIMPOT ADJUSTMENTS The control contains trimpots which have been factory adjusted for most applications. 4 illustrates the location of the trimpots and their approximate adjustment positions. Some applications may require readjustment of the trimpots in order to tailor the control to exact requirements. 3 for range and factory setting of all trimpots. ) Readjust trimpots as follows: WARNING. [. . . ] The amount of DC current is directly proportional to the motor torque. The CL trimpot is factory set at 150% of the current established by the Plug-in Horsepower Resistor ® selection. 5. ) Readjust the CL trimpot as follows: (Note: The "OL" indicator will light when the control is in CL. ) 1. Rotate CL trimpot CW until desired CL setting is reached (factory setting is 1. 5 times rated motor current). [. . . ]
