Vibration amplitude diagnosis
NAMUR module (IEC 60947-5-6) and and 8/16 mA or 4 to 20 mA model
Measurement quality is related to the vibration amplitude of the fork. The diagnostic LED
indicates the quality of the vibration being sent to the LVS200 electronics.
• Diagnostic LED off: measurement quality is good. The vibration amplitude is strong.
• Diagnostic LED blinking: measurement quality is poor and vibration amplitude is
decreasing as fork becomes encrusted. When this happens, set the sensitivity
switch to decreased sensitivity.
• Diagnostic LED on: vibration has stopped and fork is fully encrusted with material.
Current output setting
8/16 mA
The chart below illustrates the output current when:
• Fork is clean
• Fork is encrusted: weak vibration amplitude is shown
• Fork is fully encrusted and vibration has stopped.
