2 Safety information
2.1 General
The safety instructions are intended to protect people and property from damage and hazards
that could arise as the result of improper use, incorrect operation or other misuse or devices,
especially in explosive areas. Therefore, please read the operating instructions carefully before
working on the product or operating it. The operating instructions must be accessible to
operating personnel at all times.
Please make sure that all documents are present and complete before commissioning or
performing other work on the product. If the documents have not all been delivered in full or if
further copies are necessary, they can also be obtained in other languages.
The product is built according to the latest state of the art. However, hazards to people,
machinery and systems can still arise as the result of improper handling, unintended use or
operation and maintenance by persons inadequately trained on the product.
All those who are involved in the installation, operation and maintenance of the product in the
operator’s plant must read and understand the operating instructions.
The product may only be assembled, disassembled, installed and repaired by instructed,
sufficiently trained and authorised personnel.
2.2 Symbols used
This symbol indicates an explosion hazard.
This symbol indicates a hazard from electrical current.
This symbol indicates safety-related information.

3 Scope of this instruction manual
This instruction manual for the HE205-type vibration monitoring unit applies to the following
versions:
HE205.00, HE205.02 and HE205.01
The variants are functionally identical. The variants HE205.02 and HE205.01 have
additional certifications and labels which permit use in potentially exclusive atmospheres.
4 Vibration monitoring HE205
The HE205 type vibration monitoring unit is used to measure and monitor the vibration
acceleration of machinery. It offers the following features:
•Two limit values and associated delay timings can be adjusted separately.
•The two potential-free switching contacts will signal any exceeding of the relevant defined
limit values. This can be used to generate an alarm.
•Measurement parameter: vibration acceleration (g rms).
•Analogue current output: Interference-free DC signal from 4-20 mA, proportional to the
measuring range of the monitoring unit.
•A break on the monitoring cable can be detected by the subsequent evaluation device:
DC signal value < 3.5 mA.
5 Intended Use
The HE205 is used to protect machines and mechanical equipment against undue strong
vibrations. It may only be used in accordance with the specifications listed in the data sheet. It is
used exclusively for measuring mechanical vibrations.
Main fields of application: Conveyors, screening equipment, drying and cooling equipment and
similar oscillating mechanical equipment.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
6 Scope of supply
All versions include:
•Vibration monitoring
•Cylinder head screw with hex socket, M8 x 20 mm

8 Transfer of liability when operating in potentially explosive atmospheres
The owner of the system is exclusively liable for the appropriate configuration of the electrical
connections with respect to explosion protection regulations and correct commissioning.
If the system is installed by a sub-contractor on behalf of the owner, the system may only be
commissioned after the sub-contractor has issued written confirmation in the form of a certificate
of installation that the system has been installed correctly and professionally in accordance with
the applicable legal regulations.
The operator is obliged to notify the responsible authorities of the initial commissioning of
explosion-protected systems or system components and their re-commissioning following
extensive changes or maintenance.

11 Information on the cULus validity range
In order to install the device according to the UL/CSA/IEC standard, the following information
must be observed.
Electrical protection
Devices must be protected by means of fuses, circuit breakers, overheating
protection, impedance-limiting switches or similar to ensure protection against
excessive power output if there is a fault in the device. Protection must be
applied to supply lines and switching lines.
A circuit breaker suitable for 30V/3A according to UL Standard 489/CSA
Standard (C22.2) no. 5/IEC 60947-2 must be installed near the device.
A fuse suitable according to UL Standard 248/CSA Standard (C22.2) no.
248/IEC 60127 must be installed near the device. The fuse must have a slow
triggering characteristic (“T”).
Limited temperature range
The following temperature ranges apply for variants with integrated cable:
Measuring head

12 Functional safety instructions
12.1 Safety level / key indicators
The HE205 vibration monitoring hardware was tested by TÜV Süd. The results meet the criteria
according to SIL2 and Pl-d.
Safety marking placeholder1
….
Safety marking placeholder2
….
12.2 General notes
A reboot of the vibration monitoring unit must be performed annually in order to
test the switching of potential-free switching contacts.
12.3 Instructions for the Fail Safe State
When the power supply is switched on, the vibration monitoring unit will perform a self-test.
During operation, self-tests are performed automatically in cycles. If a self-test fails, the vibration
monitoring unit switches to the Fail Safe State.
In the Fail Safe State all status LEDs are lit, all potential-free switching contacts are open and
the analogue current output supplies 0 mA.

13.3 Operating range of the vibration monitoring unit
The operating range is independent from the measuring range. It can be derived from the
maximum acceleration, which is 16.5 g across all frequencies. The maximum measurable
vibration velocity is based on the formula

15 Functional description
In an explosive atmosphere the vibration monitoring unit HE205 will only be
opened in a de-energized state.
The type HE205 is used for monitoring vibration acceleration.
If the acceleration value is below or above the adjustable window area,
an alarm will be triggered. The vibration monitoring contains two channels independent from
each other, LIM1 and LIM2. The lower limit value of the window area is adjusted on LIM1 and
the upper limit value is adjusted on LIM2 (see chart).
The HE205 type also has an analogue current output. This supplies direct current of 4-20 mA
proportional to the vibration amplitude.

15.2 Alarm and limit setting
By pressing the "Save Config" button, the current configuration is displayed by the LEDs around
the HEX switches. For further information, see chapter "Limit values and delay times” on page
19.
The limit values and delay times are calibrated using the respective HEX switch. As soon as a
switch position is changed, the LEDs around the Hex switch start to blink. The number of
blinking LEDs represents the current position of the HEX switch. To save the configuration,
press and hold down the "Save Config" button for three seconds. Acceptance of the
configuration is signalled by steady lighting up of the LEDs in the selected HEX switch position.
After about five minutes the LEDs turn off automatically.
