2 Functions and features
The vibration sensor detects the vibration in the system (measured / evaluated
physical unit = vibration velocity)� This is converted into an analog signal at the
current output� The switching output behavior is determined using the two setting
rings�
3 Installation
► Mount only in a thick housing wall (e.g. transport thread).
►
Ensure that the signal direction is correct�
►
Ensure a safe vibration transmission and allow no elastic intermediate layers�
►
Tighten the sensor with a tightening torque of 15 Nm�
4 Electrical connection
The unit must be connected by a qualified electrician� The national and
international regulations for the installation of electrical equipment must be
adhered to�

5 Settings
RMS Set
Effective value of the switching threshold, defining the limit value of the vibration
velocity�
Delay Set
Time in seconds during which the limit value must be effectively above the swit-
ching threshold (RMS Set) to activate the switching output (normally closed pin 4)�
