Solenoid disabling function (-NP)
PVEH-NP and PVEA-NP have a build in feature that disables the solenoids by US at 50% and gives a
feedback on the solenoid status. This is done to facilitate application monitoring. The fault monitoring is
still activated but the closed loop will remain passive until the control signal shifts.

PVEH-F (six pin) has also the disable function but not the feedback. Our general recommendation is
disabling of PVE that are not in active use.
