Using the VSD-1C 

With the VSD-1C you can control a variable fan according to a 0-10 Volts or 4-20 mA 
input signal. Refer to figure 2 for the location of the different switches, jumpers and 
selectors of the module.

Minimum Speed Potentiometer 

This potentiometer is used to adjust the Minimum Speed of the fan. This will be 
the minimum speed when the input signal is at its minimum value.

Dip Switches (Input Range and Shutoff 5%

Dip Switch 1 is used to select the Input Range (ON = 2-10 Volts / 4-20 mA, OFF 
= 0-10 Volts / 0-20 mA). 
Dip Switch 2 is used to adjust the output behavior when the input is below 5% of 
its total range (ON = Shutoff, OFF = Runs continuously at Minimum Speed).

Input Type Jumper 

This jumper is used to select which input type is used. Two types of input can be 
used which are: 0-10 Volts (jumper on the 2 left pins) and 0-20 mA (jumper on 
the 2 right pins).
