WIRING
REVERSE CONNECTION WILL CAUSE THE MOTOR TO RUN AT MAXIMUM
UNCONTROLLED SPEED. THE DC TACHOMETER MUST BE CONNECTED
SUCH THAT THE TACH LEAD CONNECTED TO TERMINAL 519 IS MORE
POSITIVE THAN THE NEGATIVE TACH LEAD CONNECTED TO TERMINAL
419 FOR THE DESIRED DIRECTION OF ROTATION. FAILURE TO OBSERVE
THIS PRECAUTION COULD RESULT IN BODILY INJURY.
5. Connect an isolation transformer must be used between the AC
power source and the controller to isolate the controller from the AC
power source ground. Each such controller must have it's own
isolation transformer.
NOTE: Any DC2 controller used in a motor reversing application
cannot employ a DC tachometer speed feedback.
NOTE:
A DC tachometer used as a speed feedback signal for one
controller cannot be used as the speed reference signal for another
controller.
