Setpoints - Dual
The PumpSmart PS220 can be configured to use two separate and distinct setpoints, or references. The
Set-point methods or references can be configured in the same fashion that are described in the Reference
section.
For Process PID Control:
This functionality is the last step in the Process Control Wizard. The PS220 will require a selection to be config-
ured to toggle between the two setpoints.
The choices are:
1. Digital Input 3. See note 3 below.
2. A Fieldbus command. See note 3 below.
This can only be selected if Fieldbus is the Primary setpoint source. .
To access this Wizard from the Home View, follow the path:
Menu>PS220 Configuration>Process Control>Process Control Mode> (SEE NOTE BELOW) NOTE: Please
remember your selections when proceeding though this wizard to configure the dual setpoint functionality!
Next>Select>Select>Select>Next>Select>Yes>
The steps that you will follow are:
1. Configure the source for setpoint 2.
2. Configure the method to activate Setpoint 2.
3. Configure DI3 with the I/O Wizard. This is only required if DI3 is not selected in step 2.
Note:
1. Dual Set-points configuration for Speed Control cannot be done with the PS220 Configuration wizard. This
functionality will need to be configure manually. Follow the procedure as noted below.
2. Dual Set-points for use with the MultiPump Functionality will require the Digital Input used to be wired
“In-Series” with all of the drives.
3. The source for both setpoint 1 and 2 must be the same. Selecting Keypad for Setpoint 1 and an Analog
Input or Fieldbus for Setpoint 2 is not an available option.
4. This functionality cannot be used with a Start/Stop selection that requires the use of DI3. Example: HOA
DI1, 2 - DI5.
