Danfoss PVE Series 4 User Manual

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.
US disable range 48 % U
DC
to 52 % U
DC
Solenoid disable reaction time From active to passive 750 ms <-> 1000 ms
From passive to active 0 ms <-> 50 ms
Solenoid feedback signal Maximum load 50 mA
Voltage if solenoid active by load 20

Voltage if solenoid active by load 50

DC
– 2.0 V
Voltage if solenoid passive < 1 V
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.
