WARNING! Do not
earth ground any Main
Speed Potentiometer terminals
.
Note:
When mounting the Main
Speed Potentiometer, be sure to
install the insulating disc (supplied)
between the potentiometer and the
panel.

Voltage Following Connection –
An isolated*
0 – 5 Volt DC analog
signal input can be used to control
motor speed in lieu of the Main
Speed Potentiometer. The drive
output will linearly follow the analog
signal input. Connect the signal input positive lead (+) to Terminal “P2” and the negative lead
(–) to Terminal “P1”. The terminals are located on the lower PC board. With external circuitry, a
0 – 10 Volt DC analog signal can also be used. See Figure 18, on page 33.
*If a non-isolated signal is used, use Bodine model number 3984 or equivalent..
Note:
For signal following operation, the Minimum Speed Trimpot (MIN) must be set fully
counterclockwise to zero.
