Page 6: Product Description
Installation and User Guide | idSET-OTM Sensor 6/19 Product description Product operation The idSET-OTM Sensor utilises capacitive measurement and can be connected to Labkotec Oy’s idSET-OTM central units. The sensor provides the central unit with information on the oil layer accumulated on the oil separator. -
Page 7: Installation
Installation General installation instructions idSET-OTM Sensors can be installed in zone 0 explosive atmospheres. Do not remove the sensor markings from the cable or sensor frame. After emptying, the sensor must always be filled with water at least up to the lower electrode to eliminate the possibility of a potential difference between the sensor and the environment. -

The sensor can measure oil layers up to 400 mm, when the oil density is between 765… 900 kg/m^3. The alarm engagement point can be determined with the idSET-OTM control unit. The sensor provides a notification if the separator’s total surface level is outside the measurement range (e.g. - Page 9 Adjust the rigging screw to the middle position (C). The wire length is h1 = h - 280 mm (from the top loop of the rigging screw (A) to the black top surface of the sensor (D)). Figure 5 . idSET-OTM sensor suspension wire installation DOC001875-EN-2...

You should also check the operation every time the separator is emptied or at least once every six months. Checking the functioning of the idSET-OTM with the idSET-OTM control unit Functional test: The operation of the sensor can be checked by lifting it in the air, and the central unit will sound an alarm. -
Page 13: Maintenance
Due to static charge, the paper or cloth must be moist and you should also avoid rubbing motions. To facilitate cleaning of the idSET-OTM Sensor, the counter electrode can be removed by loosening the three screws at the top. -
Page 14: Troubleshooting
The measuring device must be Exi classified if the sensor is in an explosive area. Remember to set the idSET-OTM control unit in maintenance mode so that the alarms during the maintenance measures are recorded in the inspection log instead of the alarm log.
