2 Functions and features
The vibration sensor detects the vibration in the system (measured / evaluated
physical unit = vibration velocity)� This is converted into an analogue signal at the
current output� The switching output behaviour 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�

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)�
