To Next PageTo Next PageWhat to do if my KB Electronics DC Drives motor is not running but the LED is on?
If the motor of your KB Electronics DC Drive isn't running but the Power On LED is lit, the main speed potentiometer might be set to zero. Try adjusting the main speed potentiometer to your desired speed. Also, make sure the main speed potentiometer, signal input, and motor connections are all properly connected.
Why is the power LED not illuminated on my KB Electronics DC Drives?
If the Power ON LED indicator on your KB Electronics DC Drive isn't lit, first verify that the AC line connections are properly made. If they are, check the AC line fuse to ensure it hasn't blown.
