2.2 Safety during the individual phases of operation
The following safety information must be observed when installing the device and during operation.
SIGNAL WORD!
An informative text describes the danger and suggests how it can be avoided.
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.

Chapter 2 Safety information
9Operating manual HE 5710 / HE 5711
Version 1.3
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!
The original packaging protects against any electrostatic discharge.
Only transport the device in its original packaging
During assembly observe all regulations for protection against electrostatic dis-
charges.
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 respec-
tive device carrier) and a protective ground.
The cable shielding belongs to the measurement earth.
The effects of interference fields can be prevented through use of twisted and
screened measuring lines.
The respective connection diagrams / connection designs for the devices apply.
Explosion protection!
This device (the version with the Makrolon housing) is suitable for operation in
Explosion Zone 22 with the lid closed (where an explosive atmosphere may arise
due to electrically conductive dusts).
Prior to opening the device, one must ensure that there are no explosive ambient
conditions, such as dust formation.
The special regulations governing operation in an Ex-area must be observed.
Blowing of a fuse!
First determine the causes for the failure and remove them.
Only use fuses which have the same specification as the original type as a re-
placement.
Repaired fuses or short circuiting are not permissible.

Chapter 2 Safety information
Operating manual HE 5710 / HE 5711 10
Version 1.3
The following provisions must be observed:
Attach the cables to the cable glands correctly in order to retain the protection class.
Operation with an opened lid is not permissible.
The tightness of the hose screw connections/glands, for example for ∆p measurement or
measuring hose cleaning, must be checked.
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.
The device is marked with:
II3D Device category: use in zone 22 for dust during normal operation
Ex Designates an electrical equipment
tc Type of ignition protection: protection by housing

Troubleshooting!
When beginning to troubleshoot, all possible sources of error regarding additional
equipment or cables (measuring lines, 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.

Number of valves
The number of valves is determined automatically by the control unit. Recognised valves are dis-
played by lit up LEDs.
Number of full cleaning cycles
Using the coding switch CYCLES, set the number (1 – 9). The setting 0 deactivates cyclic cleaning.
The cleaning process for the set cycles is started by means of trigger signal to the START CYCLE
terminals (+ and -) .
Pulsing period of the valves
Setting using the PULSE potentiometer between 0.02 and 1.2 seconds.
Pause time of the valves
Setting using the pausing potentiometer PAUSE between 1 and 270 seconds.
