7. Input/Output Setup

Use the "DIGITAL I/O" and "ANALOG I/O" menus to activate and configure the input and output for the functions

required for the application.

Users may also reference Section 16 Menu Maps for additional configuration assistance.

Two Analog Inputs are provided for the User. Analog Input 1 is used for pump set point (flow or speed pacing)

input. Analog Input 2 is used for systems configured for analog 4-20 mA flow feedback from a user supplied flow

meter.

7.1.1 Analog Input 1 – Set point

Ensure that you have your Analog Input signal connected to the proper location before activating, See Figure 5-8

–I/O Terminal Strip Details (Panel & NEMA4x Shown)– Use Menu->Analog I/O-> Analog Input #1 to activate

the analog input signal function. The menu can be used to set the analog input to either ACTIVE or INACTIVE.

Proceed to Section 8.1.3 Set point Calibration and Range Setup to calibrate your input based upon open or

closed loop operation.

7.1.2 Analog Input 2 – Flow meter Feedback

See Section 9 Flow Meter Input for installation instructions. The flow meter input signal must be configured

properly prior to use. Use Menu ->System Setup-> Flow Meter ->Meter Type->Analog to enable the process

feedback analog input. The flow meter type must be set to "ANALOG" to enable this input. Users may also

reference Section 16 Menu Maps for additional configuration assistance.

The MPC VECTOR allows for testing of the analog inputs with approximate accuracy. Analog input

does not have to be active to use this feature. The user must provide an analog signal from a

PLC/SCADA or 4-20mA transmitter/calibrator to the input under test. See Section 5.3.3.7 Analog Input

Wiring Example for connection. To view the analog input value, proceed to

-> Analog I/O Diagnostics

Once in the Analog Diagnostics Screen the user will see the following:

A I N 1 A I N 2 A O U T

X . X X X . X X X . X

AIN1 and AIN2 show the values, in mA's, currently applied to analog input 1 and 2, respectively.

Changing the value input from the PLC/SCADA, transmitter/calibrator, or instrumentation (i.e. flow

meter) should be reflected in these two input values. If values do not change be sure to check input

control wiring (signal is polarity sensitive), PLC wiring, and flow meter connections.
