1 Legal Provisions
Manufacturer
AXXERON HESCH electronics GmbH, Boschstraße 8, 31535 NEUSTADT, GERMANY
Intended use
The HE 5411 differential pressure measuring transducer is a universal pressure
transducer, mainly used in dedusting industry. It can also be used for measuring
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.
Note!
The devices are available with as well as without ATEX approval.
Please refer to chapter 5 Device description, to find out which device
version (Lite, Basic, Premium) is approved for which EX zone.
Devices with a measuring range of ± 1.25 mbar, regardless of the
device version, are not ATEX approved!
If you have ordered an ATEX-approved device, you must necessarily
observe the safety instructions for explosion protection, the indication on
the name plate as well as the information in chapter 2.5 Device
Identification.

Explosion Prevention! (for ATEX approved devices only!)
HE 5411 Lite, Basic 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 as well as Premium with 19…36 V DC 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 absolutely
necessary to ensure that no explosive environmental conditions, such as
formation of dust or gas, exist.
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.
2.4 Special regulations
Note!
Sealing bolts must be applied professionally to cable ducts that are not
used.

4.2 Opening the device
Opening and closing is performed by hinge technology without screws. A slit screwdriver is
required to open the device. The screwdriver must be positioned at the intended position at
the housing lid (see Figure 2).
Note!
Make sure to move the screwdriver to the right to open the hinge (see
Figure 2). If the screwdriver is moved to the left, the housing cover may
be damaged.
The housing lid can be opened to the left up to an angle of 105°.
Optionally, the housing lid can be closed with 4 additional screws (see chapter 11
Accessories) in order to protect it from unauthorised access. For further information, please
contact your service representative of AXXERON HESCH electronics GmbH.
Open the housing lid to the left (figure shows similar device)

5 Device description
The differential pressure measuring transducer records the differential, over- and negative
pressure between two pressure inputs, and converts the measurement value into a linear or
square-rooted output signal of 0(4)…20 mA or 0…10 V.
The 4-digit 7-segment display of the Basic and Premium version allows the indication of
negative pressures.
5.1 Overview of device versions

From left to right: HE 5411 Lite, HE 5411 Basic, HE 5411 Premium
Explosion Prevention! (for ATEX approved devices only!)
HE 5411 Lite, Basic 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 as well as Premium with 19…36 V DC 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 absolutely
necessary to ensure that no explosive environmental conditions, such as
formation of dust or gas, exist.

Note!
Optionally, all 24 V DC devices are available with an M12 connector
(see chapter 6.1.1 Option: electrical connection via M12 connector (for 24
V DC devices only!)).
The advantage of a device with M12 connector is that it is not necessary
to open the device for electrical commissioning.
