1 Legal Provisions

Manufacturer

HESCH Industrie-Elektronik GmbH, Boschstraße 8, 31535 NEUSTADT, GERMANY

Intended use

The HE 5411 differential pressure transducer is a universal pressure transducer,

mainly used in dedusting technology. It can also be used in the measurement of

overpressure in clean rooms.

The device can be operated within the operating and environmental conditions

approved in these operating instructions without impairing its safety.

The manufacturer is not liable for improper use and any resulting personal injury or

material damage; the risk is borne solely by the user. Failure to comply with the above

criteria for intended use will result in the expiry of the warranty and liability for the

device.

Personnel qualification

All work on the differential pressure transducer may only be carried out by qualified electricians

with sufficient knowledge in the field of electrical engineering.

Device Safety

The device has been constructed and tested in accordance with VDE 0411 / EN 61010-1 and

has left the factory in perfect safety condition. To maintain this condition and ensure safe

operation, the user must observe the notes and warnings described in this manual.

Declaration of conformity

The valid declaration of conformity can be found on the internet on www.hesch.de.

2 Safety Information

2.1 Symbols and Basic Safety Instructions

This chapter contains important safety regulations and notes. To protect against personal injury

and material damage, it is necessary to read this chapter carefully before working with the

device.

Symbols used

The following symbols are used in this manual. All safety instructions have a uniform structure.

Personal Injury Warning!

The severity of the danger is indicated by the respective signal word.

Explosive region warning sign!

High Voltage Warning!

Warning of material damage caused by electrostatic charge!

Property Damage Warning!

Note!

Identifies possible malfunctions and indicates optimum operating

conditions.

2.2 Signal Words

DANGER!

Indicates an imminently hazardous high risk situation, which, if not avoided, will result in death

or serious injury.

WARNING!

Indicates a potentially hazardous medium risk situation, which, if not avoided, could result in

death or serious injury.

CAUTION!

Indicates a hazardous low risk situation, which, if not avoided, could result in minor or moderate

injury.

HE 5411 Operating Instructions

#340411 | version 1.7

2.3 Safety in the individual operating phases

When installing the device and during operation, the following safety instructions must be

observed.

Danger of Electrocution!

Before working on the device, switch off all power supplies used. The

electrical cables must be laid according to the respective national

regulations (in Germany VDE 0100). The measuring lines must be laid

separately from the mains leads.

Attention!

The device must never be put into operation even if damage is

recognisable.

Warning!

Ensure protection against short circuiting in the supply circuit.

Attention!

During installation, commissioning, maintenance and troubleshooting,

observe the accident prevention regulations applicable to your system,

e.g. DGUV Regulation 3 "Electrical installations and equipment".

Attention!

Clean dirty contacts with oil-free compressed air or with spirit and a lint-

free cloth.

Warning of material damage caused by electrostatic charge!

Observe the safety measures according to BS EN 61340-51/-3 to avoid

electrostatic discharge!

Power Connection!

The electrical cables must be laid according to the respective national

regulations (in Germany VDE 0100). The measuring lines must be laid

separately from the mains leads.

Explosion Prevention!

HE 5411 Lite, Basic and Premium with a supply voltage of 19…36 V DC

are suitable for use in explosion zones 2 and 22, provided that the lid is

closed.

HE 5411 Lite, Basic and Premium with a supply voltage of 100…240 V

AC are only suitable for use in explosion zone 22, provided that the lid is

closed.

Devices with a measuring range of ± 1.25 mbar (regardless of the device

version) do not have an ATEX certification and must not be used in

potentially explosive areas.

Before opening the device, e.g. for parameter setting, it is essential to

ensure that no explosive environmental conditions, such as formation of

dust, exist.

2.4 Device Identification

Note!

The HE 5411 differential pressure transducer is available in three

different designs. The corresponding device identification can be seen on

the nameplate. Devices with a measuring range of ± 1.25 mbar

(regardless of the device version) do not have any ATEX certification!

Troubleshooting!

At the beginning of troubleshooting, all possible sources of faults on

additional devices or supply lines (measuring lines, wiring, downstream

devices) should be taken into consideration. If the fault is not found after

checking these points, we recommend sending the device to the supplier.

Decommissioning!

Switch off the power supply on all poles if the device is to be

decommissioned. Secure the device against unintentional operation!

If the device is connected to other devices and / or equipment, the effects

must be considered and appropriate precautions taken before switching

off.

The following special regulations must be observed:

The cables must be correctly inserted through the cable ducts by a professional.

Cable ducts not required must be furnished with sealing bolts by a professional.

The ATEX certification only maintains its validity if the installation is carried out correctly by a

professional under the safeguarding of the protection class specified on the marking.

Cleaning of the housing is only permitted with moist cleaning materials to avoid static charging.

Cleaning is necessary to prevent increased dust generation on the device.

Operation under voltage, in zone 22 and 2, only in closed state.

Before closing, ensure that the device housing is free of dust.
