1 Legal Provisions
Manufacturer
HESCH Industrie-Elektronik GmbH, Boschstraße 8, 31535 NEUSTADT | GERMANY
Intended use
The HE 5760 is a master-slave control for the cleaning process of industrial dust
extraction systems.
The expansion to a complete cleaning control system is carried out with the HE 5725
valve controllers, each of which controls 12 valves. Up to 48 valve controllers can be
centrally controlled as CAN slaves by the HE 5760. The valves are assigned to so-
called filter chambers. The control is set to the existing number of chambers and
valves using the parameter menu. Parameterisation can also be carried out with the
PC software 'SmartTool' via the USB interface.
The HE 5760 control unit is located in a front-mounted housing with membrane
keypad and graphic display and is designed for installation in control cabinets. Local
operation at the control cabinet with switchgear and signal lamps that are connected
directly is possible.
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 follow all instructions and warnings in this quick guide.

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 5760 Operating Instructions
# 372449| Version 3.2
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 cables must be laid
separately from the power lines. The connection between the connector
for the functional earth (in the respective equipment carrier) and a
protective earth must be established.
Danger of Electrocution!
Any interruption of the protective earth in the equipment carrier can result
in the device becoming a hazard. Intentional interruptions are not
permitted. If there is a suspicion that it is no longer possible to operate
the device safely, it must be shut off and secured against being
unintentionally switched on.
Danger of Electrocution!
Do not open the device when it is connected to the voltage! When
opening the devices or removing covers and parts, live parts may be
exposed. Connection points can also be live!
Attention!
The device must never be put into operation even if damage is
recognisable.
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 ethyl alcohol 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!

HE 5760 Operating Instructions
# 372449 | Version 3.2
9
Power Connection!
The electrical cables must be laid according to the respective national
regulations (in Germany VDE 0100). The measuring cables must be laid
separately from the power lines.
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 being unintentionally
switched on!
If the device is linked to other devices and/or equipment, consider the
impacts and take appropriate precautions before switching it off.

7.3 CAN network configuration
7.3.1 CAN address assignment
Each device in the CAN network is addressed with its CAN node number. The assignment of
the CAN addresses must comply with certain rules.
The HE 5760 control unit does not require a CAN address.
With the HE 5725 valve controls, a distinction is made between:
one HE 5725 per chamber, consecutive numbering, 1, 2, 3, ... 48
two HE 5725 per chamber, split numbering, 1, 25, 2, 26, ... 24, 48
