1. idOil-LIQ (high liquid level):
► Immerse the sensor in oil or water.
2. idOil-OIL (oil):
► Immerse the sensor in oil. If this is not possible, lift the sensor into the air.
3. idOil-SLU (sludge):
► Immerse the sensor in sand or sludge. If this is not possible, lift the sensor into the
air.
The alarm will be activated after the delay (factory setting: 10 s).
Remember to set the device in maintenance mode so that the alarms
during the maintenance measures are recorded in the inspection log
instead of the alarm log.

Maintenance measures
The sensors must be cleaned in conjunction with maintenance inspections. You can clean
the sensors with washing up liquid and a washing up brush, for example.
Do not use corrosive substances to clean the sensors.
Mark the maintenance measures in the control unit’s inspection log.

Troubleshooting
PROBLEM:
The display is dark.
Explanation:
The voltage received by the device is too low, or the fuse has
blown.
Action:
1. First check that the voltage has not been cut by the mains
switch.
2. Measure the voltage from connectors N and L1. It should be
100–240 V AC.
DANGER OF ELECTRICAL SHOCK!
Adhere to the electrical safety regulations!
PROBLEM:
Fault alarm on (the backlight of the display is flashing)
Explanation:
The sensor cable is short-circuited, cut or disconnected from the
connector. The sensor could also be damaged.
Action:
1. Measure voltage separately from that sensor's sensor
connectors. The voltage should be 9.0–11.5 V.
2. If the voltage is correct, measure the current received by the
sensor. It should settle between 6.0–8.0 mA within 10 seconds.
3. Reconnect the disconnected wire after the measurement.
The sensor cable wires are not numbered because the voltage
polarity (+ or -) makes no difference.
