If the "Sludge alarm act." alarm appears, it means the sludge level has reached a set alarm level. In this case, separator emptying should be ordered.
What to do if "High level alarm act." alarm appears in AFRISO OSA 3 Measuring Instruments?
If the "High level alarm act." alarm appears, there may be a blockage at the outlet to the separator. Clear the blockage or find out what is causing it.
What to do if "Sensor err on input 1 (level)" alarm appears in AFRISO OSA 3 Measuring Instruments?
If the "Sensor err on input 1 (level)" alarm appears, there may be an error in the sensor circuit to the sensor, such as a cable failure or short-circuit. To resolve this, measure the voltage at the sensor.
What to do if "Sensor err on input 2 (high level)" alarm appears in AFRISO OSA 3?
If the "Sensor err on input 2 (high level)" alarm appears, there may be an error in the sensor circuit to the sensor, such as a cable failure or short-circuit. To resolve this, measure the voltage at the sensor.
What to do if "Sensor err on input 3 (sludge)" alarm appears in AFRISO OSA 3 Measuring Instruments?
If the "Sensor err on input 3 (sludge)" alarm appears, there may be an error in the sensor circuit to the sensor, such as a cable failure or short-circuit. To resolve this, measure the voltage at the sensor.
What to do if "Level alarm act." alarm appears in AFRISO Measuring Instruments?
If the "Level alarm act." alarm appears, you should order emptying.
What to do if the sensor is not connected or there is a cable failure in AFRISO Measuring Instruments?
If the sensor is not connected or there is a cable failure, connect the sensor or troubleshoot the cable.
What to do if the sensor is connected incorrectly in AFRISO OSA 3 Measuring Instruments?
If the sensor is connected incorrectly, check the polarisation.
What to do if the sensor circuit is short-circuited in AFRISO OSA 3?
If the sensor circuit is short-circuited, check the sensor circuit.
