8. Maintenance
The operation of the separator system and alarm device must be checked
at least every 6 months by experienced personnel.
The following is recommended in conjunction with the inspection:
functional check of the idOil alarm device with the test function and sensor (see Section
Functional test)
sensor cleaning (see Section Maintenance measures)
The idOil control unit and sensors do not have wearing or replaceable parts.
The device does not include replaceable fuses.
8.1. Functional test
8.1.1. Test function
The test function creates a test alarm, which is used to ensure the appropriate functioning
of the idOil device and any other possible devices or systems controlled by its relays in an
alarm situation.
The function can only be executed if no alarms are active. If this is the case, all indicator
lights are green.
Activating the test function:
► Press the reset/test button continuously for 3 seconds.
To indicate the activation of the test, the indicator lights are red to indicate the sensor’s
alarm and fault state, the relays are switched to the alarm state and the buzzer is on.
8.1.2. Functional test with sensors
The operation of the idOil device and sensors can be checked comprehensively by simply
simulating an actual alarm situation.
Depending on the sensor type, the functional test can be conducted as follows:
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).
