idOil sensor troubleshooting with idOil control unit
EXPLOSION HAZARD!
Observe the installation and maintenance instructions for explosive atmospheres!
The measuring device must be Exi classified if the sensor is in an explosive area.
idOil-30, idOil-D30: 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. For detailed instructions on how to set the device in maintenance mode, please refer to
the control unit's operation and installation manual.
The sensor cable wires are not numbered because the voltage polarity (+ or -) makes no
difference.
PROBLEM:
Explanation:
Action:
The measurement can also be carried out on the separator end by opening the cable
extension.
A Ex-classified mA current meter
B idOil-20, idOil-30 control unit's sensor connectors 9–10 or 11–12 or 13–14
C idOil-D30 control unit's sensor connectors 46–47 or 48–49 or 50–51
D idOil sensor(s)

If problems occur, contact Labkotec Oy's service department.
Fault alarm is on:
idOil-20: The sensor alarm indicator light is flashing red and the fault
indicator light is red (cable cut or loose) or the alarm indicator lights of all
sensors and the fault indicator light are red (short circuit).
idOil-30, idOil-D30: Fault alarm on (the backlight of the display is
flashing).
The sensor cable is short-circuited, cut or disconnected from the
connector. The sensor could also be damaged.
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 drawn by the sensor
as follows:
2.1 Disconnect the sensor wire from the control unit's left-hand side
sensor connector.
2.2 Connect an mA meter as shown in the figure below.
2.3 SENSOR connectors can have 1–3 sensors connected to it, with a
single sensor drawing 6.0–8.0 mA of current.
2.4 Reconnect the disconnected wire after the measurement.
