HYDRAULIC OPTIONS
14.1 Option /B
Solenoid, integral electronics and position transducer at side of port A of the main stage. For hydraulic configuration vs reference signal, see 13.1
14.2 Option /Y
Option /Y is mandatory if the pressure in port T exceeds 210 bar.
15.1 Option /F (for TEB and TES-SN; standard for TES-SP, SF, SL with fieldbus)
This option permits to monitor the eventual fault condition of the driver, as for example the solenoid short circuit/not connected, reference signal
cable broken for option /I, spool position transducer broken, etc. - see 17.9 for signal specifications.
15.2 Option /I (for all version)
It provides 4 ÷ 20 mA current reference and monitor signals, instead of the standard ±10 V
DC.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 V
DC 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
electrical noise; the valve functioning is disabled in case of reference signal cable breakage.
15.3 Option /Q (for TEB and TES-SN; standard for TES-SP, SF, SL with fieldbus)
This option permits to inhibit the valve function without removing the power supply to the driver. Upon disable command the current to the
solenoid is zeroed and the valve’s spool moves to rest position.
The option /Q is suggested for all cases where the valve has to be frequently inhibited during the machine cycle – see 17.7 for signal specifications.
15.4 Option /Z (for TEB and TES-SN; standard for TES-SP, SF, SL with fieldbus)
It provides, on the 12 pin main connector, the following additional features:
Fault output signal, see above option /F
Enable input signal, see above option /Q
Repeat enable output signal - only for TEB
Power supply for driver’s logics and communication - only for TES
Separate power supply (pin 9,10) allows to cut solenoid power supply (pin 1,2) while maintaining active diagnostics, USB and fieldbus communication.
A safety fuse is required in series to each driver power supply: 500 mA fast fuse.
15.5 Options /C - only for SP, SF, SL
Option /C is available to connect pressure (force) transducers with 4 ÷ 20 mA current output signal, instead of the standard ±10 V
DC.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 V
DC or ±20 mA.

POWER SUPPLY AND SIGNALS SPECIFICATIONS
Safety certified versions:
For SN: /IU
For SP, SF, SL: /CU, IU, CIU
Generic electrical output signals of the valve (e.g. fault or monitor signals) must not be directly used to activate safety functions, like to switch-ON/OFF
the machine’s safety components, as prescribed by the European standards (Safety requirements of fluid technology systems and components-
hydraulics, EN-982). For certified safety options /U see tech. table FY100.
17.1 Power supply (V+ and V0)
The power supply must be appropriately stabilized or rectified and filtered: apply at least a 10000 μF/40 V capacitance to single phase
rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers. In case of separate power supply see 17.2.
17.2 Power supply for driver’s logic and communication (VL+ and VL0) - only for /Z option and TES-SP, SF, SL with fieldbus
The power supply for driver’s logic and communication must be appropriately stabilized or rectified and filtered: apply at least a 10000
μF/40 V capacitance to single phase rectifiers or a 4700 μF/40 V capacitance to three phase rectifiers.
The separate power supply for driver's logic on pin 9 and 10, allow to remove solenoid power supply from pin 1 and 2 maintaining active the
diagnostics, USB and fieldbus communications.
A safety fuse is required in series to each power supply: 2,5 A time lag fuse.
17.3 Flow reference input signal (Q_INPUT+)
The driver controls in closed loop the valve spool position proportionally to the external reference input signal.
Reference input signal is factory preset according to selected valve code, defaults are ±10 V
DC for standard and 4 ÷ 20 mA for /I option.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 VDC or ± 20 mA.
Drivers with fieldbus interface can be software set to receive reference signal directly from the machine control unit (fieldbus reference). Analog
reference input signal can be used as on-off commands with input range 0 ÷ 24VDC.
17.4 Pressure or force reference input signal (F_INPUT+) - only for TES-SP, SF, SL
Functionality of F_INPUT+ signal (pin 7), is used as reference for the driver pressure/force closed loop (see tech. table GS002).
Reference input signal is factory preset according to selected valve code, defaults are ±10 V
DC for standard and 4 ÷ 20 mA for /I option.
Input signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 VDC or ± 20 mA.
Drivers with fieldbus interface can be software set to receive reference signal directly by the machine control unit (fieldbus reference).
Analog reference input signal can be used as on-off commands with input range 0 ÷ 24VDC.
17.5 Flow monitor output signal (Q_MONITOR) - only for standard, /Q, /Z and TES-SP, SF, SL
The driver generates an analog output signal proportional to the actual spool position of the valve; the monitor output signal can be softwa-
re set to show other signals available in the driver (e.g. analog reference, fieldbus reference, pilot spool position).
Monitor output signal is factory preset according to selected valve code, defaults are ±10 V
DC for standard and 4 ÷ 20 mA for /I option.
Output signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 VDC or ± 20 mA.
17.6 Pressure or force monitor output signal (F_MONITOR) - only for TES-SP, SF, SL
The driver generates an analog output signal proportional to alternated pressure/force control; the monitor output signal can be software set to
show other signals available in the driver (e.g. analog reference, force reference).
Monitor output signal is factory preset according to selected valve code, defaults are ±10 V
DC for standard and 4 ÷ 20 mA for /I option.
Output signal can be reconfigured via software selecting between voltage and current, within a maximum range of ±10 VDC or ± 20 mA.
A safety fuse is required in series to each driver’s logic and communication power supply: 500 mA fast fuse.
