(2) Average response time value; the pressure variation in consequence of a modification of the reference input signal to the valve is affected
by the stiffness of the hydraulic circuit: greater is the stiffness of the circuit, faster is the dynamic response

tandard driver execution provides on the 7 pin main connector:
Power supply - 24 VDC must be appropriately stabilized or rectified and filtered; a 2,5 A fuse time lag is required in series to each driver
power supply. Apply at least a 10000 mF/40 V capacitance to single phase rectifiers or a 4700 mF/40 V capacitance to
t
hree phase rectifiers
Reference input signal -
analog differential input with 0÷+10 V
D
C
nominal range (pin D, E), proportional to desired valve pressure regulation
M
onitor output signal - analog output signal proportional to the actual valve’s coil current (1V monitor = 1A coil current)
Note: a minimum booting time of 500 ms has be considered from the driver energizing with the 24 V
DC power supply before the valve has
b
een ready to operate. During this time the current to the valve coils is switched to zero.
9.1 Option /I
I
t provides 4 ÷ 20 mA current reference signal, instead of the standard
0
÷+10 V
D
C
.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 V or ±20 mA.
It is normally used in case of long distance between the machine control unit and the valve or where the reference signal can be affected by
e
lectrical noise; the valve functioning is disabled in case of reference signal cable breakage
9.2 Option /Q
To enable the driver, supply 24 V
DC on pin C referred to pin B: Enable input signal allows to enable/disable the current supply to the solenoid,
without removing the electrical power supply to the driver; it is used to maintain active the communication and the other driver functions when
the valve has to be disabled. This condition does not comply with European Norms EN13849-1 (ex EN954-1).
9.3 Option /Z
It provides, on the 12 pin main connector, the following additional features:
Enable Input Signal
To enable the driver, supply 24 VDC on pin 3 referred to pin 2: Enable input signal allows to enable/disable the current supply to the solenoid,
without removing the electrical power supply to the driver; it is used to maintain active the communication and the other driver functions when
the valve has to be disabled. This condition does not comply with European Norms EN13849-1 (ex EN954-1).
Fault Output Signal
Fault output signal indicates fault conditions of the driver (solenoid short circuits/not connected, reference signal cable broken for 4÷20mA
input, etc.). Fault presence corresponds to 0 V
DC, normal working corresponds to 24 VDC (pin 11 referred to pin 2): Fault status is not affected
by the Enable input signal
Power supply for driver’s logics and communication
Separate power supply (pin 9, 10) allow to cut solenoid power supply (pin 1,2) while maintaining active diagnostics, USB and fieldbus communica-
tion.
A safety fuse is required in series to each driver power supply: 500 mA fast fuse.

PROGRAMMING TOOLS - see tech table GS500
Valve's functional parameters and configurations, can be easily set and optimized using
Atos E-SW programming software connected via USB port to the digital driver. For
fieldbus versions, the software permits valve's parameterization through USB port also if
the driver is connected to the central machine unit via fieldbus.
The software is available in different versions according to the driver’s options:
E-SW-BASIC support: NP (USB) PS (Serial) IR (Infrared)
E-SW-FIELDBUS support: BC (CANopen) BP (PROFIBUS DP) EH (EtherCAT)
EW (POWERLINK) EI (EtherNet/IP)
E-SW-*/PQ support: valves with SP, SF, SL alternated control (e.g. E-SW-BASIC/PQ)
WARNING: drivers USB port is not isolated!
The use of isolator adapter is highly recommended for PC protection (
see table GS500)
