Chapter 2 InstallationSeries 830/840/860 Instruction ManualInput Signal Connections (Controllers Only)A 0-5 VDC (4-20 mA optional) set point command inputs ignal allowsyou to set the f low to any desired value within the range of thecontroller. The set point input signal is a direct linear representation of0 to 100 percent of the controller’s mass flow full scale value.For 0–5 V DC set point control, connect a manual-adjust potentiometeras shown below. Any potentiometer value between 5K and 100K maybe used but is limited to a V DC input signal only. For 4-20 mA or 0–5V DC set point control, use a PLC or other digital device.If the set point input is not connected to some type of control device,the valve on/off switch must be activated in the off position. If no setpoint command is present on the controller when powered-up and thevalve is not switched off, the valve will drift wide open.Figure 2-11.Local Command Set Point Potentiometer (15-Pin D-Connector)Figure 2-12.External Command Set Point Source (15-Pin D-Connector)2-12 IM-83/84/86-H
