"Fail to run" alarm/alert on a chemical dosing pump

"Fail to run" alarm/alert on a chemical dosing pump

On some Cloacina systems, the PLC determines whether a chemical dosing pump is running by measuring the amperage drawn on the pumps 120V power wiring within the control panel.
If the measurement device used to read this amperage is not fully tuned, a false alarm can occur.

The first strategy is to increase the amount of pump power wiring looped around the measurement device (ACS200).  This will help the unit better read the current.

The green looping on the image is attempting to show how the single wire running through the measurement module in the control panel can be looped around the module more times.




 In addition to this, the attached manual has instructions on how to set the jumpers on the switch and perform fine adjustment with the potentiometer.  Please read the "quick start' instructions within the document.


 FYI this is how the amperage measurement module is depicted on the Cloacina electrical drawings
