2 Safety instructions
● Read this document before setting up the product and keep it during the entire
service life�
● The product must be suitable for the corresponding applications and
environmental conditions without any restrictions�
● Only use the product for its intended purpose (→ Functions and features).
● If the operating instructions or the technical data are not adhered to, personal
injury and/or damage to property may occur�
● The manufacturer assumes no liability or warranty for any consequences
caused by tampering with the product or incorrect use by the operator�
● Installation, electrical connection, set-up, operation and maintenance of the unit
must be carried out by qualified personnel authorised by the machine operator�
● Protect units and cables against damage�
● The design of the unit corresponds to protection class III (EN61010) except for
the terminal blocks� Protection against accidental contact (safety from finger
contact to IP 20) for qualified personnel is only ensured if the terminals have
been completely inserted� Therefore the unit must always be mounted in a
control cabinet of at least IP 54 which can only be opened using a tool�

● For DC units the external 24 V DC supply must be generated and supplied
according to the requirements for safe extra-low voltage (SELV) since this
voltage is provided near the operating elements and at the terminals for the
supply of sensors without further protection measures�
3 Documentation
This documentation relates to the hardware and firmware status at the time of
editing this manual� The features of the devices are continuously developed further
and improved�
4 Functions and features
The devices have been designed for use in applications described in this manual
and the device-specific data sheets�
Adhere to the data indicated in the data sheets and in the manual� If the handling
specifications and safety instructions for configuration, installation and operation
indicated in the documentation are adhered to, the devices normally do not lead to
a danger for persons and objects�
5 Sensor functions
The diagnostic electronics has
– 2 analogue inputs
– 4 dynamic inputs
– 1 analogue or digital output
– 1 digital output
– 1 TCP/IP parameter setting interface
– 2 PROFINET IO ports
An analogue current signal (0/4…20 mA) or a pulse signal (HTL) can be
connected to the analogue inputs�
The analogue inputs can be used
– as trigger for measurements (e.g. rotational speed for vibration diagnostics)
– as trigger of a counter
– for process monitoring
Type VSA accelerometers can be connected to the dynamic inputs�
The dynamic inputs can be used for
– vibration monitoring

– vibration diagnostics
– analysis of other dynamic signals
Alternatively, the dynamic inputs can also be used like an analogue input with an
analogue current signal (4...20 mA).
The hardware outputs can be configured as 2 x binary (NO/NC) or as 1 x analogue
(0/4…20 mA) and 1 x binary (NO/NC).
The outputs can be used for
– time-critical alarms (e.g. machine protection, response time up to 1 ms)
– alarm output
– analogue value output of values measured by the diagnostic electronics
The parameter setting interface (TCP/IP) is used for the communication between
the diagnostic electronics and a PC (e.g. VES004 parameter setting software).
The parameter setting interface can be used for
– parameter setting of the device
– online data monitoring
– reading the history memory
– firmware update
The PROFINET IO ports are used for the communication between the diagnostic
electronics and a PROFINET controller (e.g. PLC).
The PROFINET IO interface can be used for
– transferring the current measured values, limits and alarm states of the
diagnostic electronics to the PLC
– reading the counter readings of the diagnostic electronics
– writing rotational speeds and other values from the PLC to the diagnostic
electronics
– writing limits from the PLC to the diagnostic electronics
The device is not approved for safety-related tasks in the field of operator
protection�

5.2 Function description
With the device
– vibration monitoring (total vibration to ISO)
– condition monitoring (condition-based monitoring on the basis of vibration
in real time with a very fast reaction time up to 1 ms)
can be implemented�
Monitoring of up to 24 objects (indicators for different machine parts, vibration
characteristics or process values)
– dynamic values within the time range (e.g. v-RMS to ISO)
– dynamic values within the frequency range FFT or HFFT (e.g. imbalance or
rolling element bearing)
– process values (analogue signals) for current value above or below the limit
The device has an internal history memory (600,000 values) with real-time clock
and flexible memory interval per object. The memory is a ring memory (FIFO).
Up to 32 counters can be configured to measure the duration of exceeding the
limit and/or operating times�
The signals at the inputs are permanently picked up and continuously monitored
according to the set parameters�
With objects within the frequency range (imbalance, rolling element bearing ...) the
duplex mode is used for monitoring�
With objects within the time range (v-RMS, a-RMS and a-Peak) all 4 dynamic
inputs are monitored simultaneously and without interruption�
The two outputs OU1/2 can be used for alarms� The respective object states per
sensor are also indicated via the 4 sensor LEDs�
The system LED displays the operating status of the device�
Parameter setting of the monitoring tasks and alarming is effected by the VES004
software� The software allows to display and record the current measured values,
spectra and time signals (online data).
Via the Ethernet interface of the device networking is possible to visualise data
(measured values, alarm states ...) in other systems (e.g. SCADA, MES ....).
