Operation

Priming the Pump                                              

Before priming the pump, or starting the pump, be sure that all suction and discharge lines are connected properly and that proper valves are open.  

Pressing the Prime Key will start the pump at 100% speed and will run for 60 seconds.  The pump can be stopped at any time by pressing the Start/Stop key.  All 60 seconds may not be required to prime the pump.  Conversely, if additional priming is necessary, the Prime key can be pressed again.  

If the pump does not prime, check the suction line for clogs, obstructions, or leaks. Make sure all appropriate valves are open. 

Manual Operation                                              

To run the pump in Manual Mode, ensure the “Manual Adjust / Local” light is on, or press the “Manual Adjust” key to activate (“Local” light will turn on). Press the Start/Stop key to start the pump running. Adjust pump speed by pressing the Up and Down arrow keys on the touchpad. To stop the pump, press the Start/Stop key.  

If using the pump in Remote Start Stop Mode, press the Start/Stop key to put the pump in “Ready – Standby” state. The display will read “SBY” if waiting for a signal from the user-provided control system. Once a signal is received, the pump will start. Adjust pump speed manually by pressing the Up and Down arrow keys on the touchpad.  

4-20ma Input Speed Control Mode                                             

To run the pump in 4-20mA Mode, press the “4-20mA Input” key to active (“Remote” light will turn on.) Press Start/Stop key to start the pump running. Pump speed will be set by remote 4-20mA input signal.  To stop the pump, press the Start/Stop key.  

If using the pump in “Remote Start/Stop” Mode, press the Start/Stop key to put the pump in “Ready – Standby” state. The display will read “SBY” if waiting for a signal from the user-provided control system. Once a signal is received, the pump will start. The pump speed will adjust via the 4-20mA input signal. 

To see the actual input 4-20mA signal value, press the “Display” button in the upper left of the touchpad. 

Calibration                                              

To ensure the most accurate pumping, a pump calibration is recommended prior to operating the pump.  The A1 pump flow rate will vary depending on the suction line conditions. Calibrate the pump with actual suction line conditions.     

To calibrate the pump: 

1. Connection tubing and open valves on the suction side of the pump to represent actual suction lines conditions 
2. Set up discharge and open discharge valves to dispense into calibration column/cylinder. 
3. Prime to the pump so that the calibration column begins to fill. Stop the pump and note the solution level in the calibration column.  
4. Run the pump at a set speed for 1 minute.   
5. Record the flow difference in the calibration cylinder.  
6. Calculate the flow rate by dividing the flow by the time. For example, if the pump runs for 1 minute, and the flow difference is 30 ml, then divide 30 ml by 1 minute. The flow rate is 30 ml/min.   
7. For best accuracy, run more than one calibration to check results, or run another calibration at a different pump speed.  

Calibration results should be similar to the flow rating for the pump tube, but can vary depending on chemical composition, suction lift, viscosity, temperature, and other conditions.   

Tube Failure Detection (TFD+)                                              

The A1 pump is equipped with leak detection located inside the pump head.  If a tube fails or leaks for any reason, the chemical will trigger the sensor, stop the pump, and activate an alarm.  

If TFD+ alarm occurs, the pump will stop, close an alarm output, and the screen will flash TFD+ with an alarm icon. If the system has detected chemical, the pump tube must be replaced, and the pump head and roller must be thoroughly cleaned. 

Remove the front cover to replace the tube and roller. Failure to clean the pump head properly will void warranty. See video on proper tube replacement.  https://www.blue-white.com/bw-videos/the-blue-white-academy-how-to-replace-the-a1-m1-tubing/
