Configuring the setpoint for Process Control in any mode will require two additional settings after the
configuration of the transmitter. These will scale the setpoint separately from that of the transmitter. This
scale will provide the limits on how low, or high, a setpoint can be, to prevent operation at values that
could be detrimental to the pumping systems.
To get to this screen directly to change the setpoint min and max:
MENU>PS220 Configuration> Process Control> (Push select or next 5 times)
The parameters used to adjust these manually are as shown below:
NOTE:
If you forget to set, or send a reference to the PumpSmart PS220, it will run at the minimum speed that
had been configured in parameter 30.11. A warning message will not display if the reference is 0. In
Process control mode it may run to maintain the reference but will not speed up higher than this value.
75.09 SETPOINT MIN
Defines the Minimum Process Control Setpoint. Any value below this will not be used in
the PID control.
75.10 SETPOINT MAX
Defines the Maximum Process Control Setpoint. Any value above this will not be used
in the PID control.
