Manufacturer
HESCH Industrie-Elektronik GmbH, Boschstraße 8, D-31535 Neustadt, Germany
Intended use
The HE 5422 MR Differential Pressure Regulator serves the purpose of measuring the dif-
ferential pressure using filter elements as part of the industrial fabric filter technologies and
to operate a valve control unit. The differential pressure is monitored by two alarm thresh-
olds.
The control unit can be operated within the usage and ambient conditions stated in this
manual without causing any safety risks.
The manufacturer is not liable for improper usage and the resulting personnel injuries or
damage; the risk lies entirely with the operator. Failure to comply with the above mentioned
criteria regarding intended use may void the warranty – the manufacturer cannot be held li-
able for damage to the device in this case.
Personnel qualification
Only qualified electricians with the appropriate knowledge in the field of electrical engineering are
allowed to conduct any work on the Differential Pressure Regulator.
Device safety
The device was built and tested in accordance with VDE 0411 / EN 61010-1 and has left the fac-
tory in an operationally safe condition. In order to maintain this condition and to ensure safe opera-
tion, the user has to follow the instructions and warnings contained in this manual, see chapter 2
"Safety information" on page 7.

Version 1.2
2.2 Safety during the individual phases of operation
The following safety notes must be observed when installing the device and during operation.
Danger of electric shock!
Disconnect the power supply before working on the device. Install the electrical
lines in accordance with the respectively applicable local regulations (VDE 0100
in Germany). Lay the measuring lines separately from the power lines. Produce a
connection between the protective ground connection (in the respective device
carrier) and a protective ground.
Danger of electric shock!
Any interruption of the protective ground in the device carrier may cause the de-
vice to become dangerous. Deliberate interruptions are not permissible. If it can
be assumed that safe operation is no longer possible, then the device shall be
put out of commission and be secured against unintended operation or re-activa-
tion.
Danger of electric shock!
Do not open the device under voltage! When opening the devices or removing
covers and parts, live parts may become exposed. Connecting points may also
be live!
Caution!
The device may not be put into operation when there is visible damage on the
device.
Caution!
Observe the accident prevention regulations applicable to the system, such as
BGV A 3 "Electrical Systems and Equipment" during installation, commissioning,
maintenance and troubleshooting.
Caution!
Clean soiled contacts using oil-free compressed air or spirit and a lint-free cloth.
Material damage due to electrostatic charging!
Observe the safety measures according to DIN EN 61340-51/-3 in order to pre-
vent electrostatic discharging!
Chapter 2 Safety information
10 Operating manual HE 5422 MR
Version 1.2
The following provisions must be observed:
Attach the cables to the cable glands correctly.
Provide unneeded housing bores with locking bolts.
It is only permitted to clean the housing with wet cleaning agents in order to avoid static
charging.
It is required to clean the device in order to prevent increased dust formation.
Electrical connection!
Install the electrical lines in accordance with the respectively applicable local reg-
ulations (VDE 0100 in Germany). Lay the measuring lines separately from the
power lines. Produce a connection between the protective ground connection (in
the respective device carrier) and a protective ground.
Explosion protection!
The device is suitable for operation in explosion zone 22 with the lid closed. Prior
to opening the device, it has to be ensured that there are no explosive ambient
conditions, such as dust development.
The device is marked with:
II Not suitable for mines susceptible to firedamp
3D Dusts, normal safety
T135°C Surface temperature
IP65 Protection class: dust-proof, scoop-proof
Troubleshooting!
When beginning to troubleshoot, all possible sources of error regarding additional
equipment or cables (measuring cables, wiring, slave devices) should be taken
into consideration. If no error source can be found after examining these points,
we recommend to send the device to the supplier.
Decommissioning!
Disconnect the power supply entirely if the device is to be decommissioned. Se-
cure the device against inadvertent operation!
If the device is interconnected with other devices and/or equipment, the effects of
the deactivation should be considered prior to disconnecting the device and the
appropriate precautions should be taken beforehand.
