Capacitive electrodes EL 4 … 20 mA - compact
Diagnosis
Instrument failure
No failure detected on the sensor.
Possible reasons are:
- supply voltage outside the tolerance
- defect oscillator
- damage of the electrode or the isolation
- electrode shortcircuited with the vessel wall
• Separate the sensor from the supply voltage and then connect voltage
again (cold start).
• If the fault signal does not extinguish, check the sensor line and the
correct supply voltage.
• If the fault signal does not extinguish, check the sensor on damages.
If you cannot detect any failure, call our service department.
