Product description

General information

The IFB Multi-Ethernet valve (Integrated Fieldbus) is a digital directional control valve with integrated flow controller, load-independent.

The following operating modes are possible:

• Valve direct control

• Flow control

• Pressure/force control

• Pressure control/volume substitutional

• Torque/force control/flow

• Pressure control/valve direct control substitutional

• Substitutional control (flow – pressure/force); pQ function (flow-controlled)

Communication is done via the digital Multi-Ethernet interface (X7E1 or X7E2) only. The following data may be exchanged:

• Command values

• Actual values

• Configuration and setting of the system control parameters

• Status messages, faults or warnings

Set-up

The directional control valve with IFB Multi-Ethernet electronics mainly consists of:

• Main housing with control spool (1)

• Control electronics with integrated fieldbus (3)
  • Connector, voltage supply, safety shut-down (XH1)
  • Ethernet interfaces (X7E1, X7E2)

• Pressure sensor sandwich plate (4)

• Stroke solenoid (2.1)

• Control solenoid with electrical position feedback (2.2)

Notice:

With version "V32", the control spool may rotate in case of single-sided flow through the supply flow edges (P–A or P–B) causing damage or failure of the valve. This can be solved by reduction of the pressure differential over the supply flow edge to a maximum of 80 bar or by simultaneous use of both control edges (P‒A/B‒T or P‒B/A‒T).

Flow control

The integrated electronics (OBE) enables load-independent control of the flow at positive command value by means of the two integrated pressure sensors in ports P and A. At negative command value, the flow is controlled from P to B.

Safety function (only symbol Q5-)

The integrated electronics (OBE) of the valve enable additional shut-off of a channel according to EN 13849-1 in both directions (depending on the symbol, the valve can be considered as safely shut-off).

When using symbol V, the valve cannot be used in a safety-relevant manner according to EN 13849-1 while enable acknowledgment always remains 0.

Thanks to the two control solenoids (enable pin D and E, low signal) at the connector (XH1), direction-dependent shut-off is enabled. The control spool of the valve is in spring-centered central position for this purpose (fail-safe position).

Enable acknowledgment pin C for solenoid A and pin F for solenoid B are "high". By connecting both control solenoids (enable pin D and E, high signal), the valve can be controlled by a command value presetting (command value positive, solenoid B or command value negative, solenoid A).

Enable acknowledgment pin C for solenoid A and pin F for solenoid B are "low".

Separate shut-off of solenoid A or solenoid B will moreover allow for the direction-dependent activation or shut-off of the drive.

Notice for safe shut-off according to EN 13849-1 (Enable acknowledgment)

The enable acknowledgment is not set (pin C and F):

• Regular operation, enable active:

• Enable at pin D clears enable acknowledgment at pin C, enable at pin E clears enable acknowledgment at pin F.

• For failure of supply voltage.

• In case of a cable break (the integrated electronics (OBE) will de-energize both control solenoids and the control spool will move to the spring-centered central position).

• If the control spool is not in a hydraulically safe position (insufficient safety overlap of the control spool or safe position is not reached).

Monitoring

The digital control electronics enable comprehensive monitoring functions/error detection including:

• Undervoltage

• Communication error

• Cable break for analog sensor inputs

• Monitoring of the microcontroller (watchdog)

• Temperature of the integrated electronics

IndraWorks DS PC program

To implement the project planning task and to parameterize the valve, the user may use the IndraWorks DS engineering tool (see accessories):

• Project planning

• Parameterization

• Commissioning

• Diagnosis

• Comfortable administration of all data on a PC

• PC operating systems: Windows 10

Notices:

• When using symbol V, the enable inputs (enable pin D and E) may only be activated and deactivated together.

• For all other symbols, a unilateral shut-off will cause reduced performance data.

• 4/3 directional control valves do not have a leakage-free basic locking when deactivated. Leakage must be considered when designing the drive.

• Valve type 4WRPQ (symbol Q5-) can be used as shut-off element cat. 3 or 4 (up to PL e according to EN 13849-1). For both categories, an additional shut-off element is required to achieve a two-channel shut-off. For further information on the safety application, see operating instructions 29391-B.

• At a flow command value of 0, the specified flow control tolerance also applies.

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Bio-degradable and flame-resistant – containing water: If components with galvanic zinc coating (e.g. version "J3" or "J5") or parts containing zinc are used, small amounts of dissolved zinc may get into the hydraulic system and cause accelerated aging of the hydraulic fluid. Zinc soap may form as a chemical reaction product, which may clog filters, nozzles and solenoid valves - particularly in connection with local heat input. Flame-resistant – containing water: Due to increased cavitation tendency with HFC hydraulic fluids, the life cycle of the component may be reduced by up to 30% as compared to the use with mineral oil HLP. In order to reduce the cavitation effect, it is recommended - if possible specific to the installation - to back up the return flow pressure in ports T to approx. 20% of the pressure differential at the component. Dependent on the hydraulic fluid used, the maximum ambient and hydraulic fluid temperature must not exceed 50 °C. In order to reduce the heat input into the component, the command value profile is to be adjusted for proportional and high-response valves.

Block diagram / pin assignment

1)	Not with "VARAN"
2)	Safe deactivation with simultaneous use of enable acknowledgment

Detailed description of the safety function:

After both enable signals have been removed, both output stages, and thus the solenoid A and B of the valve, are internally separated from the available supply voltage. The enable acknowledgment will only be activated for shut-off of A and B separately after the safe valve spool position has been achieved.

For a detailed description of the safety function, refer to the operating instructions 29391-B.

Project planning information

Project planning and maintenance instructions

• The supply voltage must be permanently connected, as otherwise bus communication is not possible.

• If electro-magnetic interference is to be anticipated, suitable measures must be taken to ensure the function (depending on the application, e.g. shielding, filtration).

• The devices have been tested in the plant and are supplied with default settings.

• Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to retransfer the corresponding user parameters.
