Options P1D1, P2D2 – electric two-position control with PCOR and electric BPD
P1 – electric prop. 12 V / de-energized = min. displacement with electric prop. PCOR 12 V
D1 – with electric propor. PCOR / with electric BPD 12 V, de-energized BPD = PCOR active at port A
P2 – electric prop. 24 V / de-energized = min. displacement with electric prop. PCOR 24 V
D2 – with electric propor. PCOR / with electric BPD 24 V, de-energized BPD = PCOR active at port A

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.
For formulas to calculate pressure level dependent on input current please see
