Programming OptiPumpMD - PID Setup

This article will guide users in programming the controller for the OptiPumpMD using PID to control the speed.

• Press the Setup Menus button 
• Log in to the "Master Parameter Entry" to access all parameters. 
  • The default password is "0"

Pump Setup will control the speed parameters

Start/Stop Entry Edit will control the start/stop parameters

Analog Sensor Setup Screen will allow you to configure analog devices like transducers to the controller

Digital Input Configuration will allow you to configure digital devices like switches or contracts. 

VFD Parameters will set the parameters on the VFD if the unit is configured to a Fuji Mega. This capability will not be an option with any other brand.

• Select Pump Setup
• Change the control type to "VFD Mode: PID" and then select "Configure PID Setup"
  • this will take you to another screen to configure the PID
• Select how you want to control the speed. AI2=discharge pressure or AI3=level sensors
• The default values will be set to...
  • P-Gain: 100
  • I Delay: 10
  • D Gain: 0
• Set the pressure/level to hold

When you are done, you can "Return to Menu" and select "Start/Stop Entry/Edit" 

• Select the Start/Stop Source that you are using to control the unit
• Set the Start and Stop points for your application

When you are done, you can "Return to Menu" and select "Analog Sensor Setup Screen."

These analog sensors are additional shutdown/alarms that you may use alongside the Start/Stop control. The following items need to be changed to operate the analog sensor.

• Name:
• Low Range:
• High Range:
• Units:
• Low Shutdown/Alarm:
• High Shutdown/Alarm:

Use "Alarm Only" to send a message that a SCADA system can read and send notifications if the level meets the alarm value without shutting down the unit.

"Shutdowns" can be used with a transducer to stop a pump when it meets your programmed shutdown values.

To configure an Alarm or Shutdown, the "Low" and "High" configurations must be set to the appropriate value. For example, if you want the unit to shut down at a low value and a technician reset the unit, set the value to 0. But if you want the unit to shut down and restart after a specific time, set the value to 1. Be sure to select the correct configuration for the application.

When you are done, you can "Return to Menu" and select "Digital Input Configuration."

These digital inputs are additional Alarms or Shutdowns in addition to your Start/Stop control. A digital input may be a device like a switch or a contact that closes or opens to tell the panel it is unsafe to run. 

The following changes need to be made to operate the digital input being used:

• Name
• Expected State - Does the contact open or close to indicate a problem?
• Startup Delay - The system will wait this amount of time after the pump is started to look at this input.
• Detection Time - If the contact indicates a problem, wait this long before acting on it.
• Restart Time - Wait this long before restarting if timed reset is enabled.
• Action - Select if the input will shut down the unit and if the unit will automatically restart.
