This document contains symbols for the identification of warning messages and of informative
messages.
Warning Messages
You will find warning messages, whenever dangers may arise from your actions.
It is mandatory that you observe these warning messages for your personal safety
and in order to avoid property damage.
Depending on the risk level, the warning messages are displayed in descending order
as follows:
Informative Symbols
Action
This symbol indicates a paragraph with instructions. You are prompted to perform an action
or a sequence of actions.
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt the device and any connected systems and plants,
or result in their complete failure.
Note

Product Description
2 Product Description
2.1 Function
The following vibration sensor versions are described in this manual:
General
The vibration sensor is used to measure and monitor absolute bearing vibrations in machines
in line with DIN ISO 10816. The effective vibration acceleration value is used
as the measurement parameter.
The vibration sensor determines the vibration variable using rms (root meas square)
averaging. This form of quadratic averaging or pre-filtering enables precise trend statements
about the condition of the application.
The device has 2 switching thresholds LIM1 and LIM2 and the corresponding delay times,
which can be adjusted separately.
The device also has an analog current output. This current output supplies a direct current
of 4 mA to 20 mA proportional to the vibration variable.
Some device versions have an analog current output for the output
of the bearing status parameter, see table above. This output is not safety relevant.

Device with Pre-Alarm and Main Alarm
The device evaluates the vibration amplitude in two independent channels.
If the vibration variable is exceeded, this is signaled at the switching contacts.
The switching contacts can be used to generate a pre-alarm and a main alarm.
Figure 2.1 Vibration sensor with pre-alarm and main alarm
Device with Window Function
The lower switching threshold of the window area is adjusted on LIM1 and the upper switching
threshold is adjusted on LIM2. If the acceleration value is below or above the adjustable
window area, an alarm will be triggered.
