2 Safety Notes

This chapter summarizes the general safety aspects of the system. Further points to observe are

emphasized in the corresponding subchapters.

2.1 Obligations and Liability

In order to protect the health of personnel and to avoid unnecessary damage, all of the

recommendations of the manufacturer concerning safety must be explained to every member of

the team taking part in installation, operation or maintenance of the system.

VERMES Microdispensing does not accept any liability for material damages or personal injury

originating from inappropriate use, violation of safety prescriptions, or any procedure

inconsistent with the instructions of this manual. The general rules for prevention of accidents as

well as local environmental regulations must be in place and thoroughly followed by the

personnel.

2.1.1 Obligations of the Customer

In view of a trouble-free operation of the microdispensing system, the customer has to select his

personnel carefully:

• Unauthorized use must be prevented. Persons ignoring the fundamental requirements of

industrial safety, environmental protection and prevention of accidents are not allowed to

work with the system.

• New operators must correspondingly be instructed and trained, so that they can understand

and put into practice the instructions of this manual. For certain measures, a particular

qualification may be required.

• The manual must remain accessible at any time.

2.1.2 Obligations of the Operator

All persons in charge of the system must:

• Continuously respect the general rules for prevention of accidents.

• Be aware of the safety notes of this manual. This is necessary also for operators trained by the

manufacturer or experienced in work with similar systems.

• Consult the manufacturer in any case of doubt. Applications beyond the scope of the

specification and improvised repair work must be avoided.

2.2 Residual Risks

The microdispensing system has been developed and designed with the common requirements

of safety in mind, and corresponds to the current state of technology. In the delivered layout, it

complies with the following regulations and directives:

• 2014/30/EU Electromagnetic Compatibility

• 2011/65/EU Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic

Equipment (RoHS 2013-01-03)

• DIN EN 61010-1 (VDE 0411) Safety Requirements for Electrical Equipment for Measurement,

Control and Laboratory

• DIN EN ISO 12100-1 and DIN EN ISO 12100-2 Safety of the Machinery, Fundamental Terms

• DIN EN 60204-1 (VDE 0113) Safety of the Machinery, Electric Installations of Machinery, Part 1

General Requirements

• DIN EN 982 Safety Requirements for Fluid Power Systems and their Components – Hydraulics

Safety Notes

VTK-TR-BA-072e-1 - User Manual MDS 358X Series

Despite this comprehensive inherent safety structure, the operation of the microdispensing

system may entail danger

• For the health of the operator or a third party,

• For the system itself,

• Or give rise to another material damage.

Therefore, the use has strictly to be limited:

• To the intended application.

• To a state in which the technical safety of the system can be guaranteed (i.e. it is strictly

forbidden to start or continue the operation whenever a defect has become obvious).

You have to solve problems immediately, if they have a potential to impair safety aspects. For

this reason, it is imperative that this manual remains accessible any time without delay. In an

emergency, a short reaction time may be crucial.

If you transmit the system to any other department or institution, this manual must accompany

it.

2.3 Contracted Use

The system MDS 3580 has been designed for ultra-precise contactless dispensing of fluids in a

large range of viscosity (up to 2000000 mPas), in unfilled or filled state (also with abrasive

extenders), to be operated in a conveniently equipped industrial or laboratory environment.

Deviations from the instructions of this manual must explicitly be authorized by the

manufacturer (in writing); otherwise his liability with regard to the guarantee becomes null and

void.

This includes:

• Extensions and changes of design

• Modifications of the system, or spare parts not recommended by the manufacturer

• Inappropriate material selection (lack of compatibility between parts and dispensed fluids)

• Operation with damaged parts or after improvised repair

• Dispensing of fluids able to affect the functionality of the system (in case of doubt, consult

manufacturer)

• Manipulation or absence of integrated safety devices or sealings

• Repair by persons or enterprises not authorized by the manufacturer

• Operation beyond the scope of the specification

• Auxiliary equipment not recommended by the manufacturer

• The system is not admitted for applications in hazardous locations (ATEX zones)

In no event shall we be liable under our guarantee or any other provision of the agreement for

damages resulting from a violation of the instructions of this manual.

For further questions concerning current applications and modifications of the system with

respect to new requirements, contact the manufacturer, the responsible sales partner or the

Technical Support.

2.4 Specification and Technical Notes

• The system is designed for interior use only. Maximum altitude: 2000 m.

• The relative air humidity shall not surpass 80 % rH at 31 °C or 50 % rH at 50 °C (with a linear

decline).

• Temperature: 10 °C till 50 °C

• Admissible mains voltage fluctuations: Within the range of ± 10 % of rated voltage.

• Transient overvoltage tolerated acc. to IEC 60364-4-443, max. degree of soiling: 2

• Mains cables must feature a protective conductor. In the case of cables not delivered by

Vermes Microdispensing, the guarantee for the MDS is valid only up from the interface.

• Power outlets must comply with common safety prescriptions.

• During the application, you must guarantee sufficient air circulation. For further details, refer

to Installation chapter (see paragraph 6.3.1 "Installation of the Control Unit", page 49).

For exact dispensing results, the temperature of the actuator system should stay below 80 °C

and the temperature at the outside of the valve body should stay below 39 °C. Therefore, you

might need cooling. Cooling is achieved by compressed air, free of fine particles, dust, oil and

condensate, quality classes 1, 4, 2 acc. to DIN/ISO 8573-1:2010.

- Solid particles: Quality class 1

max. number of particles/m³: 0.1 – 0.5 µm: < 20000, 0.5 – 1 µm: < 400, 1 – 5 µm: < 10

- Water content: Quality class 4

max. pressure dew point +3 °C

- Residual oil: Quality class 2

0.1 mg/m³ max.

2.5 Warnings

• Handle the mains cables correctly: Always seize the cable at the plug. Never touch it with wet

hands.

• Under no circumstances connect a schuko-plug (type F, CEE 7/4) with a socket build for an

unearthed plug (type C, CEE 7/17). The system would not be grounded.

• The cable should never be squeezed or kinked. Never place the instrumentation (or any other

object) on the cable.

• Damaged cables may give rise to fire and danger caused by electricity. Inspect them visually

in regular intervals. You should exchange damaged parts at once.

• In the case of a major disturbance, disconnect the equipment immediately from the mains.

• Spare parts not delivered or recommended by the manufacturer could affect the inherent

safety of the system. The same problem arises, if the customer attempts to process

substances not admitted for the dispensing system.

• Unqualified repair work often causes major damages, sometimes even personal injuries.

Therefore, repair is reserved to our Technical Support and authorized subcontractors.

• Before removing the actuator and sensor cable, the system must be switched OFF.

• For longer interruptions, switch OFF the control unit.

• Before disconnecting the control unit from the mains, switch it OFF.

• Repeatedly switching ON and OFF the equipment may reduce the lifetime of the power unit.

• Before charging the fluid system with an aggressive, reactive or toxic substance, you have to

verify that it is compatible with all of the contacting components inside the system.

• The supply pressure at the cartridge or in the pressure tank of 7 bar resp. 100 bar (according

to the system configuration) should never be exceeded.
