Detail:

Two modes of speed regulation:
• External potentiometer: through this potentiometer speed regulation;
• External voltage: external 10VDC voltage speed regulation;
Note: The two speed regulation can not be used simultaneously
• Speed output PG signal: There is a 5 hite part is up and down, then twang it up and down. For the toggle switch, the white part is horizontal, and the twang horizontally.
