2.1 About this chapter

The test device described in the following has 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 service case

with the test device on to third parties.

2.2 Intended use

The test device is suitable for activating and functional testing of Bosch Rexroth

servo valves without integrated electronics.

The technical data of the device have to be observed without exception, and the

speciﬁed ambient conditions have to be adhered to, see RE 29681.

The use in potentially explosive atmospheres is not permitted.

The device is provided for temporary use in a controlled electromagnetic

environment (according to EN 61326-1, table 3, testing according to EN 61326-

2-1) on hydraulic industrial equipment for commissioning, analyzing, testing and

servicing of hydraulic valves in plant.

Dry and clean ambient conditions have to be ensured.

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

test device is operated outside the indicated performance limits and operating

conditions, especially the prescribed ambient conditions.

The test device is not provided for use in Class B environments (domestic/

residential). Should the test device nevertheless be used in a domestic/residential,

controlled electromagnetic environment (emission limit values of class B), further

measures have to be taken to prevent electromagnetic interference.

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.

Expert knowledge means, amongst others:

• the ability to read and completely understand circuit diagrams,

• in particular, completely understanding the correlations regarding safety

equipment and

• knowledge of the function and structure of hydraulic components,

• knowledge of the function and structure of electrical systems and components.

When working with the test device on a system/machine, it is advantageous if

the work is carried out by a specialist who is familiar with the system!

It is assumed that the device is used by trained and professional personnel in a

controlled electromagnetic environment to ensure proper usage.

Bosch Rexroth offers training courses that support your qualiﬁcation in speciﬁc

ﬁelds. You can ﬁnd an overview of training contents on the Internet at: http://

2.6 Product-speciﬁc safety instructions

WARNING

No functional safety!

Valves control movements in machines or systems. In the case of mechanical and

electrical faults, e.g. failure of the power supply, persons may get caught, hurled

or crushed by the installation.

▶ When using the test device in a system/machine make sure that it will not

make the functional safety of the system/machine ineffective or affect it in

whatever way!

Non-observance of control signals on the system side!

If control-side safety precautions are provided, they will be rendered ineffective.

▶ The test device may be used exclusively by personnel who are familiar with the

device, the valve and the hydraulic system. No liability is accepted for damage

caused by operating errors.

10/28 Safety instructions

Bosch Rexroth AG, VT-SVTSY-1-1; RE 29681-B/11.2019

WARNING

Hazardous movements!

It is not allowed for persons to stay within the range of motion of the machines,

in which the test device is to be used. The following are examples of possible

measures against unintended access of persons:

• Protective fences

• Protective grids

• Protective covers

• Warning signs, barrier tapes

▶ If persons have to enter the hazard zone while the control is active, provide

superordinate monitoring functions on the system side or measures for

personal safety. These measures must be provided according to the speciﬁc

data of the system and on the basis of the risk and error analysis of the system

manufacturer/user. In this connection, the safety provisions applied for the

system must be taken into account.

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

shut down the test device and the valve immediately and report the faults to

the responsible personnel.

System parts under pressure and ejecting hydraulic ﬂuid!

When working on hydraulic systems with stored pressure energy (accumulator

or cylinders working under gravity), valves may even be pressurized after the

pressure supply has been switched off. During installation and demounting, the

valves or parts may be hurled around and cause personal injuries and/or damage

to property. There is moreover the risk of serious injury caused by a powerful,

ejecting hydraulic ﬂuid jet.

▶ Before installing the test device in the hydraulic system, ensure that the

hydraulic system is depressurized and the electrical control de-energized.

▶ Completely depressurize machines and systems before working on hydraulic

products.

Improper mounting or placement!

The test device is a mobile device, which is not provided for ﬁrm installation in

the system/machine. While being used, the device is connected to the measuring

line and is placed loosely in/on the system.

▶ Place the device so that it cannot fall down.

▶ Place the device so that no one can step on it.

▶ Make sure that the measuring line does not pose a risk of stumbling for third

parties or the operator himself/herself.
