Description
This alarm occurs only during calibration. The flowrate measured at the maximum control and one half of the maximum control output was nearly the same. Less than one half of the control output range is useable. The system may still function even though this alarm has occurred. This might be caused by low fluid pressure, a faulty transducer or regulator or the wrong I/P transducer being installed (100 psi range instead of 50 psi range).
Remedy
Increase the fluid pressure. Check that the transducer is functioning properly and that it is has the correct pressure range, change it if appropriate. The system might operate, but performance can be improved with one of the above remedies.
