Analog Inputs
The PumpSmart PS220 has two configurable analog inputs as standard. By default,
both inputs are current sourced and set to a scaled value of 4 to 20 mA. Each can
be independently changed to a 0 to 10VDCvoltage sourced input by changing a
jumper position on the control board. See the Pic below:
The jumpers by default are in the 2 top positions on both inputs.
Each input can also be undependably filtered, inverted, and scaled. The number of
analog inputs can be increased to five by installing an optional FIO-11 I/O extension
card in slot 3 on the control board.
When using many of the PS220 Configuration wizards, the inputs that you need
will automatically be configured. If you need to incorporate additional inputs that
have not yet been configured to complete your configuration, you can use the
PS220 configuration Wizard.
To add the FIO-11 I/O extension card from the home view follow the path:
Menu>PS220 Configuration> I/O Configuration>Yes > Wait for the software to load.
When configuring an Analog Input, you will need the information listed in the tables below:
Table 1. Identity’s what the Individual Analog Input will be used for, or its Name configuration.
These choices are listed in the table below. For both IA1 and AI2:
Parameter Name Value/Range NOTES
76.01 or
76.02
AI1 CONFIG or
AI2 CONFIG PROC TRANS 2 Used for the Multivariable control functionality.
PROC TRANS 1 Used as the primary process transmitter for Control Mode.
EXT SETPOINT1 Used for the Primary External Setpoint
EXT SETPOINT2 Used for a Secondary External Setpoint for the Dual Setpoints
functionality.
FLOWMETER Used when Flow is used for the Control Mode or for use
with Smartflow Pump Protection
DISCH PRESSURE Used with Advanced SmartFlow.
SUCTION PRESS Used with Advanced SmartFlow
DIFF PRESS Used with Advanced SmartFlow
TEMPERATURE Used when Temperature is the primary Control Mode or when a
temperature transmitter is required for Specific Gravity
correction with Smartflow.
VISC/SG VALUE Used when a correction is required for Specific Gravity
with Smartflow.
SPD OVRRD Used for the external reference for the Speed Override
functionality.
LEVEL Used when Level is the primary process transmitter for Control
Mode.
FLOW REF Used for the Primary External Setpoint for the Flow Control
Mode
PRESSURE REF Used for the Primary External Setpoint for the Pressure Control
Mode
TEMPERATURE REF Used for the Primary External Setpoint for the Temperature
Control Mode
