Notes:
a. The DC voltage signal can be applied by an external power supply or using the built-in
10VDC source and an additional potentiometer (5kΩ to 10kΩ);
b. Maximum speed adjusted (see item 6.3);
c. Solution minimum speed (lowest value of the speed range);
d. Input signal (V DC, mA DC, %) supplied to the respective remote input.

cation;
Make sure that all unused conductors in control cable are insulated to avoid prod-
g
uct malfunction or damage.
The connection between the Yellow cable (10VDC power source) and the red
g
cable (DC current) will damage permanently the DC current speed control.
