2 Instruction Manual Scope
The present instruction manual of Vibration Control Type 663 is applicable for the models:
Standard, Zone-1-21 and Zone-2-22.
The functionality of these models is identical. In addition, they have certifications and labellings
allowing their operation in potentially explosive atmospheres. (see Sect. 7, Operation Areas).
3 Vibration Control Type 663
5 Safety Level
The hardware, vibration control Type 663, was tested using Exida's FMEDA. The results of the
FMEDA meet the criteria according to SIL2, SIL3 and PL-d.
For more information, refer to the safety manual.
4 Intended Use
Type 663 is used to protect machines and mechanical equipment against undue mechanical
vibrations. Its use is only allowed within the specifications as per the data sheet, and exclusively
for measuring mechanical vibrations. Main areas of application: Industrial fans, ventilators,
blowers, electric motors, pumps, centrifuges, seperators, generators, turbines, and similar
oscillation mechanical equipment.

6 Documents and Certificates
Vibration Control Type 663 is used for measuring and monitoring the bearing vibration of
machines as per DIN ISO 10816. It offers the following features:
• Two limit values and two associated delays are seperately adjustable.
• The two relay outputs signal if the adjusted limit values are exceeded.
This can be used to generate a pre- and a main alarm.
• Measurement parameter: The root mean square (rms) of the vibration velocity (mm/s).
• Analogue current output: Interference-free direct current from 4...20 mA, proportional to the
vibration amplitude.
• Cable break on the control cable can be detected by a donwstream evaluation unit:
Value of the direct current signal < 3.5 mA.
In determining the safety function, using the safety key figures in accordance with the standards
mentioned under item 4 in the safety manual, the relay contacts of the vibration control Type 663
were explicitly evaluated and taken into account. The current output 4...20 mA is not configured in
a safety-relevant manner.
