analog signal voltage to P2 (signal) and P1 (-) ter-
minals. Adjustment of the MIN trimpot may be
necessary to achieve a 0 Volt DC output with a
0 Volt DC input.
Note: The input signal can be non-isolated or
earth grounded since the KBWS has built-in sig-
nal isolation.
E. Inhibit Circuit Connection – The
control is supplied with an inhibit con-
nector (CON1). See Figure 7. This
circuit is used to electronically stop
the control. When the Inhibit Switch is
closed, the control will coast-to-stop.
When the Inhibit Switch is opened,
the control will accelerate to the Main
Speed Potentiometer setting.
F. Enable Circuit Connection – The
control can also be started and
stopped with an Enable Circuit
(close to start). See Figure 8. The
Enable function is established by
wiring a switch in series with the
high side of the Main Speed
Potentiometer lead which connects
to the P3 terminal. When the
Enable switch is closed, the control
will accelerate to the Main Speed
