For detailed wiring diagrams and resistor selection charts, you should refer to the full BC138 - BC139 DC Control Manual . If you'd like, I can help you:
The drive comes factory-calibrated, but you can use the internal trimpots to customize performance: : Set the minimum and maximum motor speeds. bc138.rar
: Adjust how quickly the motor reaches full speed or slows down. For detailed wiring diagrams and resistor selection charts,
: Use the barrier terminal block for connections. Secure the AC line inputs and the motor armature leads (A+ and A-) according to the BC138 Installation & Operating Manual . bc138.rar
