Main Speed Potentiometer Connection
The main speed potentiometer can be connected in several ways using terminals 10, 11, 12, 13. (A 5K
ohm potentiometer is supplied with control. A 10K potentiometer can also be used.)
Caution: Terminals 10, 11, 12 and 13 are not isolated from AC line. Do not ground (earth).
A. Unidirectional operation only - Connect potentiometer to terminals 10, 12, 13 for forward direction.
Connect to terminals 11, 12, 13. for reverse direction. See Figures 2-4A and 2-4B.
B. Bidirectional operation using user supplied, SPDT, FWD/REV Switch - Connect potentiometer and
switch to terminals 10, 11, 12, 13. See Figure 2-4C.
C. Bidirectional operation with potentiometer - Connect potentiometer to terminals 10, 11, 12. See
Figure 2-4D.

Voltage Following
An isolated analog voltage can be used in lieu of main speed potentiometer. Connect signal to
terminals 12 and 13. See Figure 4-5.

Note: Terminal 13 is common. A positive signal with respect to terminal 13 will produce a positive output
to motor. A negative signal with respect to terminal 13 will produce a negative output. A 0 to ±10
VDC is required to operate control from 0 to ± full output. If required, use the (Optional) BC212,
Signal Isolator.
