An instruction is indicated by "►":
Example: ►Check whether the unit operates correctly.
Important note
Non-compliance can result in malfunctions or interference
Information
Supplementary note
1. SAFEY INSTRUCTIONS
•Please read the product description prior to set-up of the unit Ensure that the product is
suitable for your application without any restrictions
•The unit conforms to the relevant regulations and EC directives.
•Improper or non-intended use may lead to malfunctions of the unit or to unwanted effects
in your application
•That is why installation, electrical connection, set-up, operation and maintenance of the
unit must only be carried out by qualified personnel authorised by the machine operator
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.
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 switching
threshold (RMS Set) to activate the switching output (normally closed pin 4)
6. MEASUREMENT RANGE
Velocity Range
0-25 mm/sec or 0-50mm/sec
0-1 IPS or 0-2 IPS
Iout
4-20mA
Response delay
1- 60 sec

7. SWITCHING OUTPUT BEHAVIOUR
1: Time delay after the switching threshold has been exceeded
2: Time delay after the switching threshold has been exceeded
3: Switch-off
4: Switching threshold
5: Delay
Vss = vibration
velocity t = time
Implementation of the time delays
The time delay starts when the defined switching threshold is exceeded (1) / (2)
The time delay is cancelled when the value falls below the switching threshold (without
switch-off) The switch-off is triggered when the switching threshold is exceeded during a full
time delay (3)

8. OPERATING AND DISPLAY ELEMENTS
1) locking ring
2) setting rings (manually adjustable after unlocking)
3) LED green: voltage supply
4) M8 process connection
5) LED yellow: lights when switching threshold and time delay areexceeded
6) setting marks
To achieve the setting accuracy: first position the rings to the lower end stop value, then
set the requested value
