Note: Connect power supply directly to the MagnaValve first and then run power back to the control using minimum 16 AWG
wire size to prevent (high current ) voltage drops. Power supply should be regulated and rated at 50VA per valve.
Alternate: Long length of current loop may cause
inaccuracy. To keep the 0-5 Amp current loop short
you may place the .05 ohm shunt at the transformer
terminals and run 18AWG shielded cable from shunt
to control.
NOTE: The Controller's Full Scale display (typical
100.0) must match the customer's current
transformer rating (typical 100:5 ratio). Adjust the
control display range to match the actual
transformer ratio. See instruction manual.
