Reference/Setpoint Source
The Reference or the Setpoint that PumpSmart PS220 will be maintaining will need to be configured. The keypad
included is the default choice. An external source can be used that may require wiring with proper scaling values
(minimum and maximum). The PS220 also has the capability to establish limits of the overall scaling to prevent oper-
ations below and above thresholds for any particular system when using Process Control. The configuration Wizards
that are part of the Basic Startup and Process Control will guide you through this configuration.
This functional setting can only be configured using the PS220 Configuration Wizards. To access this form the Home
View, follow the paths:
For Speed Control: MENU>PS220 Configuration>BASIC Startup>
For Process Control: MENU>PS220 Configuration> Process Control> (Push select or next 5 times)
The steps you will need to go through will be as follows.
Configuring the setpoint source. The choices are:
1. Keypad (Default)
2. Analog Input (AI1, AI2)
3. Fieldbus Control
1. Keypad:
This is the default setting when configuring the drive for the first time.
2. Analog Input:
An analog signal can be sent into the drive, from a PLC, DCS or another form of controller.
The signal will need to be wired into any unused analog input AI1, or AI2.
NOTES:
For all Analog Inputs to be used:
1. “AI# scaled at AI min” refers to the speed value that corresponds to the minimum of the signal or the 4mA scaled
value. This is defaulted to 0 RPM.
2. “AI# scaled at AI1 max” refers to the speed value that corresponds to the maximum of the signal or the 20mA
scaled value. This is typically the motor nameplate speed or slip speed.
(# = refers to the choice of the physical number of the AI used)
NOTE: If your input wired signal provided is DC Voltage, please refer to the options and features section for prop-
er parameter settings of the drive. A Jumper connection on the hardware will need to be moved. (J1, or J2) This is
shown in the wiring diagrams.
