12-24 VDC - 8A - 1 Channel - Brushless DC Motor Controller

The LC-241 control box is designed for PA-14 and PA-14P brushless actuator compatibility. These actuators need to be custom-ordered for the PA-14 brushless customization. 

Actuator speed adjustments and directional actuator control are made possible by configuring the ports of the LC-241 according to the instructions of our user manual.

Speed Control Model: Open loop or closed loop control.

Speed Adjustment 1 (SPD2):

• Internal potentiometer, reduce speed by rotating CCW and increase by rotating CW
• Short circuit between “SPD” and “GND”

Speed Adjustment 2 (SPD):

• Add a potentiometer between “SPD” and “GND”
• Linear relationship between speed and voltage
• Rotate internal potentiometer to MINIMUM in CCW direction

Start/Stop (RUN):

• Short circuit between “RUN” and “GND”
• Stop if open circuit

Reverse (REV):

• Short circuit between "RUN", "REV" and "GND"
• Stop if open circuit

Follow the LC-241 wiring diagram from the datasheet for full details on brushless actuator wiring. The wires are typically green, blue, and white, which will connect to the U, V, and W terminals, respectively. If the wires are different colors, connecting them in the wrong order will simply move the electric linear actuator in the opposite direction than intended. Use a screwdriver to ensure the brushless motor wires are tightly secured to the screw terminal connections. 

Brushed DC motor controllers output consistent power and would reverse output polarities to switch travel direction, while a brushless DC motor controller like the LC-241 outputs power at the right timing to the different motor coils for motion. The actuator motor type differences between brushed vs brushless actuators and how they operate limit the LC-241 compatibility with brushless DC-motored actuators only.

The LC-241 accepts 12–24VDC power input, so use a power supply and brushless actuator that have a matching voltage within this range and ensure current draw does not exceed 8A. Exceeding the 8A actuator current limit triggers the controller overload protection error code (LED flashes 1 time) and will stop operation.
