Configure the maximum scaled value of the AI# transmitters signal.
“AI# scaled at AI# max” refers to the transmitter value that corresponds to the maximum of the
signal or the 20mA scaled value. The default value is 100.
NOTES
1. If the transmitter provided requires DC Voltage, please refer to the Analog Input section in this
manual, for proper parameter settings of the drives analog input. A Jumper connection on the
hardware will need to be moved. (J1, or J2)
2. Differential pressure flowmeters [e.g. orifice plate, venturi, etc.] do not produce signals that are
linear with flowrate. The PumpSmart PS220 cannot accommodate these types of flowmeters.
3. Refer to the transmitter manufacturer’s documentation for the proper wiring instructions, and
to determine the correct scaled values needed for configuration. This information may be printed
on the device’s nameplate.
4. The software automatically defines the selected analog input to “PROC TRANS 1” as the prima-
ry process transmitter for the system.
5. Configure the scaling of the Setpoint.
The setpoint limits, SETPOINT MIN and SETPOINT MAX, are the values, below and above, that the
system cannot be operated at. These can be different from the scaled values
configured for use.
If the process variable chosen is SmartFlow, then only SETPOINT MIN and SETPOINT MAX are
shown and need to be defined. SETPOINT MIN will typically not be zero while SETPOINT MAX
should be set at a value equal to the maximum flow of the pump. Be sure that you complete the
SmartFlow Wizard prior to running your process or the feedback will be incorrect.
Detailed Information on how configure the Setpoint Limits can be found in this manual. Please
refer to “Setpoints”
6. Configure the Source of the Setpoint.
The source can be selected from the PS220’s Keypad, an Analog Input, or a Fieldbus Control
command.
Detailed Information on how configure the Setpoint Source can be found in this manual. Please
refer to “Setpoints”
