2 Safety instructions

2.1 General

► Observe these operating instructions� ► Observe the warning notes in these instructions�

Non-observance of the instructions, operation which is not in accordance with use as prescribed below, wrong installation or incorrect handling can affect the safety of operators and machinery�

2.2 Installation and connection

The unit must only be installed, connected and put into operation by a qualified electrician as the safe function of the device and machinery is only guaranteed

when installation is correctly carried out� The installation and connection must comply with the applicable national and international standards� Responsibility lies with the person installing the device�

This is a class A product which is intended for use in industrial applications� The unit may cause radio interference in domestic areas� In this case it can be necessary for the user to take appropriate measures�

2.3 Tampering with the device

Tampering with the device is not allowed and will lead to an exclusion of liability and warranty� Tampering with the device can affect the safety of operators and machinery�

3 Functions and features

Monitoring of

• vibration velocity v

rms

or v

peak

• process value above or below the permissible value Visualisation of

• process values

• switching states

4 Installation

Please note the following points when installing the unit:

• Mount only in a thick housing wall (e�g� crane hook thread)�

• Mount vertically to the machine surface using the spacer adapter in the direction of the strongest vibrations� This is usually the radial direction�

• Tighten the M5 screw with a tightening torque of 7 Nm�

► Ensure a reliable vibration

transmission� Avoid any elastic intermediate layers�

5.1 M8/USB interface

► First connect the interface cable to the device and then to the USB interface of

the computer�

• The units have a serial number which can be read out using the PC software�

• The sensor can also be supplied via the USB interface�

• Read out and reset the history values�

Switching and analogue outputs are not supported if an USB power supply is used�

5.2 History values

The unit records history values� The memory interval is 5 min,� the maximum V

rms

value in this time range is recorded with a time stamp� Recording period about 3 years, the oldest values will then be overwritten (ring

memory)� The history can be read out and reset using the software VES004�

5.3 Real-time clock

The unit has an integrated real-time clock including a buffer battery for the time stamp in the history memory� The time is synchronised with the system clock via the PC software when the history is reset�

6 Functions

6.1 Input function

Parameter setting via the Mode/Enter and Set buttons�

• External sensor for any process value (typically temperature (°C, °F))

• Scaleable input (4��20 mA) Evaluation of the measurement results as for vibration objects

- Switch points early warning and main alarm adjustable

- For main alarm < early warning → lower limit monitor

- Adjustable hysteresis

6.2 Output function

6.2.1 Switching output and analogue output

Parameter setting via the Mode/Enter and Set buttons�

OU1 Analogue

output

- 4��20 mA scaleable measuring range of the vibration velocity

- averaging adjustable

- 22 mA in case of a system error

Switching output

- early warning

- SP 1

- NO / NC adjustable

- switch-on and switch-off delays adjustable

- 1 Hz pulsing in case of a system error

OU2 Switching

output

- main alarm

- SP 2

- NO / NC adjustable

- switch-on and switch-off delays adjustable

6.2.2 Lower limit monitor

If the SP1 switch point early warning has a higher value than the SP2 switch point main alarm, these are set as lower limit monitor�

If a lower limit monitor is set, early warning OU1 and main alarm OU2 are influenced as follows:

- If the value is greater than SP1, OU1 and OU2 are not active�

- If the value is between SP1 and SP2, only OU1 is active�

- If the value is below SP2, OU1 and OU2 are active�

The same applies to the external sensor�

6.2.3 Output logic

The process values "vibration velocity" and "external sensor" are combined via a logic OR and provided at the switching output�

example: 1

process value vibration velocity

process value external sensor

example: 0

example: 1

1: process value vibration velocity 2: process value external sensor 3: switching output

6.3 Measuring function

The device can be set to the measurement mode via the VES004 software� In this mode, you have access to the raw data (time signal) of the acceleration or of the external input (4��20 mA)� The data can be visualised, recorded, analysed and processed in the software�

If the device remains connected to the software, the user has to actively (manual

ly) finish the time signal monitoring� If the device is separated from the software, it automatically returns to the monitoring function�

If the unit is in the measurement mode, there is no monitoring� "rSc3" is displayed on the unit�
