4.2. Configure the minimum scaled value of the AI’s transmitters signal. AI1 (2).
1. “ARROW RIGHT” to change
2. “ARROWS” to change value
3. “Save”
4. “ARROW DOWN”
“AI1 (2) scaled at AI1 (2) min” refers to the transmitters value that corresponds to the minimum of the signal or the
4mA scaled value. The default is 0.
4.3. Configure the minimum scaled value of the AI’s transmitters signal. AI1 (2).
1. “ARROW RIGHT” to change
2. “ARROWS” to change value
3. “Save”
4. “ARROW DOWN”
“AI1 (2) scaled at AI (2) max” refers to the transmitters 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). The defaults are for current, both in the upper most connections. See the picture below:
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 instruction and to determine the
correct scaled values. This information may also be printed on the device itself.
