P4WRE 6

FUNCTION

The P4WRE6 is a direct acting

sol

enoid valve which combines the

directional control with the velocity

control of the consumer.

The controlled nominal flow is

proportional to the electrical input signal

at the coil.

Analogue to his size the coil creates a

force and moves the piston against the

spring. Herewith the corresponding

cross section diameters are opened

which determines the flow rate in

dependence of the pressure differential.

The integrated digital electronics permits

a better performance of the valve and

function by

- shortened response times

- reduced hysteresis

- better repeat accuracy

NOTE 1: preview on the Pin A (24 VDC) an external fuse for protecting electronics. Fuse characteristics: 5A/50V type fast.

NOTE 2: preview 24V DC on the PIN C to activate the card power stage.

NOTE 3: The input signal is differential type on E0 version only. For double solenoid valves, with positive reference signal

connected to pin D, the valve opening is P - A and B - T. With zero reference signal the valve is in central position. For “SA”

single solenoid valves, with positive reference to pin D, the valve opening is P-B and A-T. The spool stroke is proportional to

UD - UE. If only one input signal (single-end) is available, the pin B (0V power supply) and the pin E (0V reference signal)

must be connected through a jumper and both connected to GND, electric panel side.

NOTE 4: This value changes, as shown in the table below. When MONITOR function is enabled and the card is enabled, read

the test point pin F in relation to pin B (0V). When detect a failure or error of the sensor LVDT, the drive bring the valve back

in central position and locks it. In this condition the pin F, referring to the pin B, indicates 0V DC output. To reset the fault, the

card must be disabled and re-enable. When the card is disabled, the pin F referred to the pin B shows 2.7V DC output: this

value is given by the voltage of the LIN bus communication and not by the MONITOR value.
