Installation and Operating Instructions | idOil-20
Normal situation
High liquid level alarm
Oil alarm
Sludge alarm
Fault alarm 1
Fault alarm 2
Alarm has stopped
The level of the liquid being measured is below the high level
sensor (idOil-LIQ), the oil sensor (idOil-OIL) is in water and the
sludge sensor (idOil-SLU) is in water.
The indicator lights for voltage supply, sensor alarms and faults
are green.
Relays 1 and 2 are energised.
The liquid level has reached the high liquid level sensor (idOil-
LIQ).
The alarm light of the high liquid level sensor is red.
The other indicator lights are green.
The buzzer sounds after an approximately 10 second delay.
Relay 1 is de-energised after a 10 second delay.
Relay 2 stays energised.
The oil layer has reached the idOil-OIL sensor's alarm
switching point.
The alarm light of the oil sensor is red.
The other indicator lights are green.
The buzzer sounds after an approximately 10 second delay.
Relay 1 is de-energised after a 10 second delay.
Relay 2 stays energised.
The sludge level has reached the idOil-SLU sensors's alarm
switching point.
The alarm light of the sludge sensor is red.
The other indicator lights are green.
The buzzer sounds after an approximately 10 second delay.
Relay 1 is de-energised after a 10 second delay.
Relay 2 stays energised.
There is a fault in the sensor or sensor cabling.
The voltage supply indicator light is green.
The indicator light of a faulty sensor circuit alarm blinks red and
the fault indicator light is red.
The buzzer sounds after an approximately 10 second delay.
Relay 1 stays energised.
Relay 2 is de-energised after a 10 second delay.
There is a short circuit in the sensor or sensor bus.
The voltage supply indicator light is green.
The sensor alarm and fault indicator lights are red.
The buzzer sounds after an approximately 10 second delay.
Relay 1 stays energised.
Relay 2 is de-energised after a 10 second delay.
Once the alarms have stopped, the sensor alarm indicator
lights are green, the buzzer goes silent and the relays are
energised after a 10 second delay.
