2 Safety instructions

2.1 About this chapter

The valves on Multi-Ethernet basis described below have been manufactured

according to good engineering practice. However, there is still a risk of personal

injury and/or damage to property if you do not observe this chapter and the safety

instructions in this documentation.

 Read this documentation completely and thoroughly before working with the

product.

 Keep this documentation in a location where it is accessible to all users at all

times.

 Always include the required documentation when you pass the valve on to third

parties.

2.2 Intended use

A valve on Multi-Ethernet basis is a valve with electrical control for use in two-

channel safety applications (cat. 3, PL d and cat. 4, PL e according to EN 13849-1)

as switch-off element for one channel.

Depending on the application and the requirements of work equipment-related

standards according to EN 13849-1, the user must provide appropriate monitoring/

plausibility checks which comply with the required diagnostic coverage DCavg using

a higher-level control.

The valve is exclusively intended for integration into a machine or system or to

be assembled with other components to form a machine or system. The product

may be commissioned only if it is integrated in the machine/system for which it is

designed.

The operating conditions and the performance limits speciﬁed in the technical data

sheet must be observed.

The valve on Multi-Ethernet basis may be used as follows:

• For open and closed-loop (alternating) control of position, pressure, force,

velocity, pressure differential and ﬂow

For operation of the device, a higher-level control logic with appropriate I/O

components is additionally required, which, in conjunction with the valve on Multi-

Ethernet basis, holistically controls the motion sequence of the machine and also

monitors it in terms of safety.

RE 29391-B/05.2021; 4WRPD(H), 4WRPQ(H), 4WRPF(H), 4WRLD, 4WRLF, 4WRLQ, 5WRPF10, 5WRPQ10, Bosch Rexroth AG

The valve must not be used in potentially explosive atmospheres. The product is

intended exclusively for professional use and not for private usage.

Intended use includes having read and understood this documentation completely,

especially chapter 2 “Safety instructions“.

2.3 Improper use

Any use deviating from the intended use is improper and thus not admissible.

Improper use voids any warranty claims. It is also regarded as improper use if

the valve is operated outside the indicated performance limits and operating

conditions, especially the prescribed ambient conditions.

Bosch Rexroth AG does not assume any liability for damage caused by improper

use. The user assumes all risks involved with improper use.

2.4 Qualiﬁcation of personnel

The activities described in this documentation require basic knowledge of

electrical installation, control technology, programming and hydraulics as well

as knowledge of the appropriate technical terms. In order to ensure safe use,

these activities may only be carried out by an expert in the respective ﬁeld or an

instructed person under the direction and supervision of an expert.

Experts are those who are able to recognize potential hazards and apply the

appropriate safety measures due to their professional training, knowledge and

experience, as well as their understanding of the relevant requirements pertaining

to the work to be undertaken. An expert must observe the relevant speciﬁc

professional rules and have the necessary hydraulic expert knowledge.

Hydraulic expert knowledge means, amongst others:

• Reading and completely understanding hydraulic circuit diagrams,

• in particular, completely understanding the correlations regarding safety

equipment and

• knowledge of the function and structure of hydraulic components.

The operation of the digital IAC Multi-Ethernet axis control requires that the

operator is familiar with the IndraWorks Ds PC program. For a description on

handling the program as well as ﬁrst steps for operation, please refer to

https://www.boschrexroth.com.

We recommend that users attend a product-speciﬁc training by Bosch Rexroth.

Bosch Rexroth offers training courses in speciﬁc ﬁelds. You can ﬁnd an overview

of training contents on the Internet at: https://www.boschrexroth.com

cause personal injuries and/or damage to property. Therefore, only use a product

for safety-relevant applications if this use is expressly speciﬁed and permitted

in the documentation of the product, or if the safe suitability of the product in

the application is conﬁrmed by a separate conformity assessment procedure,

e.g.in explosion protection zones or in safety-related parts of control systems

(functional safety).

• Do not commission the product until you can be sure that the end product (for

example a machine/system) where the Rexroth products are installed comply

with the country-speciﬁc provisions, safety regulations and standards of the

application.

• Please observe the safety-relevant information and risk speciﬁcations in the

operating instructions of the manufacturer of the connected hydraulic system

before commissioning the control with a hydraulic system.

• Please observe the general installation and safety regulations when working on

electrical systems.

• The information given in the product documentation with regard to the

use of the supplied components represents only application examples and

recommendations. The machine manufacturer and system installer must check

the suitability of the supplied components and the information given in this

documentation with regard to their use self-dependently for his individual

application and adjust it to the safety regulations and standards valid for his

application, and carry out the required measures, changes and amendments.

• Technical data as well as connection and installation conditions are available in

the product documentation and must be imperatively observed.

• In case of faults impairing the safety and changes in the operating behavior, shut

down the valve immediately and report the faults to the responsible personnel.

• Generally, you may not modify or convert the product, except for the pilot oil

supply of the pilot-operated valves 4WRLD, 4WRLF and 4WRLQ.
