    Plug-in Horsepower Resistor®. The standard model, BC140, controls all motors through 3/4 HP at 115 Volt AC line input and 1-1/2 HP at 230 Volt AC line input. By installing the Auxiliary Heat Sink (see Table 1-2), the horsepower range is increased to 1 HP at 115 Volt AC line input and 2 HP at 230 Volt AC line input.

    Do not connect AC power to the Motor terminals A1 and A2. Connecting AC power to these terminals may damage the control. Caution: Baldor recommends not to use Grounded Leg Delta transformer power leads that may create ground loops. Instead, we recommend using a four wire Wye. Caution: Suitable for use on a circuit capable of delivering not more than 5,000 RMS symmetrical short circuit amperes listed here at rated voltage.

    Important Considerations Motor Type The BC140 / BC140-FBR is designed for permanent magnet (PM) and Shunt Wound DC motors. Controls operated on 115 Volt AC line input are designed for 90 Volt SCR rated motors. Controls operated on 230 Volt AC line input are designed for 180 and 90 Volt (step-down) SCR rated motors.
  • Page 11: Startup & Adjustments

    Startup & Adjustments The Voltage Select Switch is located under the cover and must be set before applying power to the control. Figure 2-4. For 208/230 Volt AC Line Input Set the Voltage Select Switch to the 230 position (factory setting). The switch toggle should be in the lower position with 230 displayed at the top.
  • Page 12 For moderate changes in the maximum speed, there will be a slight effect on the minimum speed setting when the minimum is set to zero. There may be significant variation in the minimum speed setting if the minimum speed is at a higher than zero setting. Acceleration Trimpot (ACCEL) The ACCEL Trimpot is provided to allow for a smooth start over an adjustable time period each time the AC power is applied or the Main Speed Potentiometer is adjusted to a higher speed.

    Troubleshooting The BC140 / BC140-FBR has LEDs to display the control’s operational status. Power On (PWR ON) LED and Pilot Light When the AC power is applied to the control and the On/Off AC Line Switch is set ON, the PWR ON LED, on the PC board, will illuminate green and the Pilot Light, on the front cover, will illuminate orange.
