Sensitivity adjustment possible. Tape version: The material surface must be compact (the sensor weight cannot sink in).
- Page 37 Nivobob Continuous level measuring system ® NB 3000 Technical information / Instruction manual Diagnostics: Maintenance Result is an indication for the user with still valid measurement. Red LED is blinking. Relay 4 indicates Maintenance (programmable). The signal enables a preventive maintenance. Evaluating the signal can help to avoid losing the sensor weight inside the silo. If Maintenance was indicated, the measurement process can be continued.
- Page 38 Nivobob Continuous level measuring system ® NB 3000 Technical information / Instruction manual Diagnostics: Maintenance Rope/Tape lifetime The expected life time (measurement cycles) for the rope/tape is: Rope version: approx. 100000 Tape version: approx. 250000 Note: These values refer to lifetime tests under the following conditions: No excessive material influence.
- Page 39 Nivobob Continuous level measuring system ® NB 3000 Technical information / Instruction manual Diagnostics: Failure Result is an invalid measurement. Red LED is on. Relay 3 indicates Failure. The signal indicates critical situations. Evaluating the signal can help to avoid losing the sensor weight inside the silo. If Failure is indicated, the unit must be checked on site.
