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 Modbus TCP 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
VSA, VSP or standard IEPE acceleration sensors can be connected to the
dynamic inputs�

6
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 Modbus TCP ports are used for the communication between the diagnostic
electronics and a Modbus TCP client/master (e�g� PLC)�
The Modbus TCP 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 teach values from the PLC to the diagnostic electronics
The device is not approved for safety-related tasks in the field of operator
protection�
5.1 Firmware
►Recommendation: Install the firmware to use all device functions�
The firmware can only be updated via the VES004 PC software� Only the firmware
of the entire device can be updated�

5.2 Functional overview
With the device
– vibration monitoring (total vibration to ISO)
– condition monitoring (condition-based monitoring on the basis of vibration
characteristics)
– machine protection/process monitoring (monitoring vibration characteristics
in real time with a very fast response 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
multiplex 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, ����)�

8
Data (e�g� measured values, alarm states, limits, rotational speeds, timer readings,
���) is exchanged between the diagnostic electronics and the Modbus TCP client/
master (e�g� PLC)�
6 Installation
►Mount the unit in a control cabinet with a protection rating of at least IP 54 to
ensure protection against accidental contact with dangerous contact voltages
and against atmospheric influence�
The control cabinet should be installed in accordance with local and national rules
and regulations�
►Mount the unit vertically on a DIN rail�
►Leave enough distance to neighbouring heat sources and between the unit and
the top or bottom of the control cabinet to enable air circulation and to avoid
excessive heating�
►Prevent the penetration of conductive or other dirt during installation and wiring�
When preparing for cable installation, the local conditions and the corresponding
mounting regulations are very important� Cables can be installed, for example, in
cable ducts or on cable bridges�
Data corruption and loss
A minimum distance between the cabling and possible sources of
interference (e�g�, machines, welding equipment, power lines) is defined
in the applicable regulations and standards� During system planning and
installation, these regulations and standards must be taken into account
and observed�
Protect the bus cables from sources of electric/magnetic interference and
mechanical strain�
Observe the following guidelines regarding "electromagnetic compatibility"
(EMC) to keep mechanical risks and interference to a minimum�
6.1 Sources of interference
Signal cables and power supply lines should not be installed in parallel�
►If necessary, metal isolating segments should be placed between the power
supply lines and signal cables�
►During installation, all connector locking mechanisms (screws, coupling nuts)
must be firmly tightened in order to ensure the best possible contact between
shielding and ground� Before initial startup, the ground or shielding connection
of cables must be checked for low-resistance continuity�

UK
9
6.2 Cable routing in control cabinets
►Install network/bus cables in separate cable ducts or separate cable bundles�
►Where possible, do not install network/bus cables parallel to power supply
lines�
►Install network/bus cables at least 10 cm away from power lines�
6.3 Installation instructions
