Caution
If the signal to the PPCOR is lost or drops below the range shown in the chart, the PCOR setting will
potentially increase to pressure levels above the recommended application limits or the regulated
pressure control of the pump, and in effect, disable the PCOR function.
The PCOR pressure level can be proportionally changed with the input current to the solenoid.
