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.
Prime mode can be accessed by pressing the App Drawer key. Then press the “Prime” key to enter Prime mode. In Prime mode, press the Start key. The pump will run at 100% speed for 60 seconds. The pump can be stopped at any time by pressing the Stop key.
Manual Speed Adjust
The initial/default mode of the pump will be “Manual Speed Adjust.” Verify that you are in Manual Mode by noting the operating mode at the top of the touchscreen. Adjust pump speed by pressing the Up and Down arrow keys on the touchpad. Pump speed can also be adjusted by pressing the Settings key. Pump speed (flow rate, RPM) can be set to a specific value.
Remote Start/Stop
If using the pump in Remote Start/Stop Mode (indicated by “RSS1” on the left side of the touchscreen), press the Start/Stop key to put the pump in “Standby” state. The display will read “STANDBY” if waiting for a signal from the user-provided control system. Once a signal is received, the pump will start.
Other Operating Modes
To run the pump in other operating modes (4-20mA, Frequency, Pulse Input, Manual Cycle Adjust, Dispensing), press the App Drawer Key, and then press the desired operating mode key. Pump will go into desired run mode.
Calibration
When in any of the operating modes, the pump can be calibrated by pressing the “Tube Calibration” key.
To ensure the most accurate pumping, a pump calibration is recommended prior to operating the pump. The M3S pump flow rate will vary depending on the suction line conditions. Calibrate the pump with actual suction line conditions.
To calibrate the pump:
- Connection tubing and open valves on the suction side of the pump to represent actual suction line conditions.
- Set up discharge and open discharge valves to dispense into calibration column/cylinder.
- Prime the pump, or run the pump in Manual Speed Adjust, pump so that the calibration column begins to fill. Stop the pump and note the solution level in the calibration column.
- Put the pump into Calibration mode by pressing the “Tube Calibration” key.
- Enter the desired calibration values for pump speed and run time in seconds.
- Press Start key.
- Pump will run for the time selected. Observe pump and calibration for proper filling. When the pump stops, measure the amount pumped by reading the calibration column level, noting the difference from starting position.
- Enter the amount pumped on the screen and press enter. The pump will calculate maximum tube flow rate automatically.
- The pump is now calibrated. Review calibrated Maximum Flow Rate by pressing Tube Calibration key.
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.
When a new tube is installed in the pump, we recommend running a calibration after the pump tube has broken in after approximately 30 minutes.
Tube Failure Detection (TFD) and Tube Information
The M3S 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 with an red alarm. 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.
At any time, tube information can be accessed by pressing the Tube Info key.
The Tube Information screen will show: Tube Type installed, Tube install date, Tube run hours & revolutions, and current Maximum tube flow rate.
