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�

6.3 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�

7.3 Operating mode

The user must be familiar with the units used in the vibration sensor ([mm/s] or [in/s]) and in the external sensor (°C, °F, mBar)�

The LEDs OU1 and OU2 indicate the alarm condition, not the voltage level (high, low) at the output� The level can be inverted via the parameters OU1 and OU2 (NC, NO)�

7.4 Operating mode external process value

In the operating mode "External process value" measured values are displayed, e�g� pressure values (mBar, hPa��), temperatures (°C, °F)�

The detected values are transferred via the measured value input (pin 5)�

8 Parameter setting

Vibration velocity, external process value and self-test parameters can be set via the Mode/Enter and Set buttons�

8.1 Vibration velocity

For the operating mode vibration velocity the following parameters can be set:

- Measurement method (rms or peak)

- Display in mm/s or in/s

- Switch points

- Lower limit frequency (2 Hz or 10 Hz) configurable

- Averaging

- Switch-on and switch-off delays

- Switching outputs (NO, NC or analogue for OU1)

If OU1 is selected as analogue:

► Scale current output�

8.2 External process value

For the operating mode external process value the following parameters can be set:

- Scaling 4 mA (EASP), 20 mA (EAEP)

- Switch points

- Hysteresis

- Switching outputs (NO or NC)

8.3 Self-test

Trigger and carry out a self-test� The self-test is carried out when the sensor is switched on and can also be

triggered manually → [tESt]. Self-test passed → [PASS], self-test failed → [FAIL]

> LED OU1 pulsing (flashes) > Output OU1

- pulsing if digital (NC, NO)

- supplies 22 mA if analogue

14

8.4 Averaging

8.4.1 Calculation

Formula to determine the new diagnostic value: ("previous diagnostic value" x (1 - averaging)) + ("new measurement" x averaging) = new diagnostic value Example Averaging 0�25; "previous diagnostic value" 17�3 mm/s; "new measurement" 14�7 mm/s (17�3 mm/s x (1 - 0�25)) + (14�7 mm/s x 0�25) = 16�65 mm/s

For the VNB001 the measured time between "previous diagnostic value" and "new measurement" is 0�25 s�

8.4.2 Settings

Averaging = 1: averaging deactivated Averaging = 0�01: strong averaging
