The solenoid valve control HE 5731 is used for cleaning industrial filter systems. The
number of valves is from 1 to a maximum of 64, and can be scaled, using modular exten-
sion units. The cleaning and de-dusting with HE 5731 can be carried out time-controlled
or differential pressure-controlled. It can be operated with, as well as without an actual
valve control. A total of 64 valves can be controlled at one time.
The controller can be operated within the operating and environmental conditions ap-
proved in this manual without impairing its safety.
The manufacturer is not liable for improper use and any resulting personal injury or mate-
rial damage; the risk is borne solely by the user. Failure to comply with the above criteria
for intended use may result in the expiry of the warranty and liability for the device.
All work on the solenoid valve control may only be carried out by qualified electricians
with sufficient knowledge in the field of electrical engineering.
This documentation is intended for all electrically qualified people, who design, install, set
up, and adjust the HE 5731 filter controller.
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.

Safety Information
2.2.Safety in the individual operating phases
When installing the control unit 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 regula-
tions (in Germany VDE 0100). The measuring lines must be laid sepa-
rately from the mains leads. The connection between the connection for
the functional earth (in the respective device carrier) and a protective
conductor must be established.
Danger of Electrocution!
Any interruption of the protective conductor in the device carrier can lead
to the device becoming dangerous. Intentional interruptions are not per-
mitted. If it is suspected that safe operation is no longer possible, the de-
vice is to be decommissioned and secured against unintentional opera-
tion.
Danger of Electrocution!
Do not open the device while it is live! When opening the devices or re-
moving covers and parts, live parts may be exposed. Connecting points
can also be live!
WARNING!
The device must never be put into operation despite any visible damage.
WARNING!
During installation, commissioning, maintenance and troubleshooting, ob-
serve the accident prevention regulations applicable to your system, e.g.
DGUV Regulation 3 "Electrical installations and equipment".
WARNING!
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!

Technical data
Explosion Prevention!
The device is suitable for use in explosion zone 22. Before opening the
device, it is essential to ensure that no explosive environmental condi-
tions, such as dust generation, exist.
Troubleshooting!
At the beginning of troubleshooting, all possible sources of faults on addi-
tional devices or supply lines (measuring lines, wiring, downstream de-
vices) should be taken into consideration. If the fault was 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 decommis-
sioned. 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.
