Application Notes
The speed adjust potentiometer (P1), supplied with the control, is
only one of many methods which can be used to control the motor
speed. With any alternative methods, these precautions must be
followed for proper control operation:
a. A 10K ohm (±5%) total resistance path must be maintained
between the gray and violet leads.
b. Any replacement resistors or potentiometers must be
capable of carrying 10 milliamps.
c. The three speed adjust circuit leads (brown, gray and violet)
should NOT be bundled with the motor or power line leads.
d. If the length of the three speed adjust circuit leads exceeds
18 inches (0.5m), then a shielded cable must be used. Do
not ground both ends of the shield.
