1. Introduction This instruction manual covers the MagnaValve models listed in Table 1. A pre-Amp is used to provide a flow rate signal and transmit it back to the FC Controller as a 0-5 Vdc analog signal with ±10% accuracy.

The Pre-Amp is factory calibrated and should not require any customer attention. The fullscale output voltage feedback signal of the Pre-Amp is 5.00 Vdc. The pre-amp uses an oscillator circuit and inductive sensor to detect metal density (shot flow) and converts this frequency into a 0-5 Vdc output feedback signal. 3.

sired value then adjust the Model FC Front panel span adjustment until it does. I. A catch test can be run to verify the accuracy of the maximum flow rate of the MagnaValve. If necessary, Adjust the Pre-Amp span adjustment ( not the FC controller span adjustment) and repeat the catch and weigh tests until the correct amount of shot is caught. Adjust the span once at any desired flow rate for proper flow then fill in the chart to check performance. J.
