Understanding the Main Display


Notification Bar

The notification bar is located across the top of the display screen, providing information such as the pump's operating mode, alarms status, time, and more. The bar can display up to 10 different icons; refer to the manual for a complete list of icons and their meanings.


Main Operating Mode Display

The main operating mode display shows the pump's current flow rate in gallons or liters per hour and the flow rate percentage, which the user programs.


Context-Sensitive Menu Buttons

The bottom of the screen features icons and their corresponding context-sensitive menu buttons:

  • Mode: Changes the pump's operation between six possible modes: Manual, Analog, Pulse, Batch, Cycle Timer, and Timed Event.

  • Prime: Starts priming the pump (default is 60 seconds at 100% but customizable in settings).

  • Lock: Locks or unlocks the keypad with a user-selected 4-digit PIN.

  • Settings: Takes you to a settings menu.


Side Buttons and Indicators


Start/Stop Button

The Start/Stop button starts or stops the pump. The green LED Pump Status Indicator lights up when the pump is operating and turns off when the pump is stopped.


100% Button

The 100% button sets the pump to its maximum predetermined flow rate.


Tank Level Indicator

The tank level indicator icon corresponds to an LED used when configured for an external tank and connected to a digital input. The LED illuminates amber when the tank is low.


Up and Down Arrows

These arrows are used to increase or decrease the flow on the main display screen. Hold the button to scroll to the desired setting.
