The service life of the NOX sensor on the CAN bus/NOX sensor module depends on the type installed:
NOX sensor |
Service life |
---|---|
P/N 56.03.003 |
8,000 operating hours with ambient temperature max. +90 °C (+194 °F) at evaluation unit |
P/N 56.03.002 |
6,000 operating hours with average temperature of evaluation unit at +90 °C (+194 °F) |
After this time the NOX sensor must be replaced. The total operating hours of the NOX sensor are displayed in the Sensor view of the respective NOX monitor (see section Sensor). You obtain a replacement sensor from MOTORTECH.
The replacement of the NOX sensor is detected by the EasyNOₓ and logged in the logbook of the respective NOX monitor.
Proceed as follows to replace the NOX sensor:
Operational safety! To safely dismount the NOX sensor, be sure to observe the following:
|
Operational safety! The NOX sensor must not be used any further under any circumstances if it is damaged or the sensing element of the NOX sensor has been mechanically shocked (e.g. by dropping it on the floor or impacts on the sensing element). In these cases, contact MOTORTECH for sensor replacement (see Customer Service Information). |
Operational safety! Proper functioning of the NOX sensor is only guaranteed if the sensing element does not overheat at the mounting location. Avoid accumulated heat at the sensing element and ensure sufficient ventilation of the sensing element by ambient air. |
Operational safety! The sensing element of the NOX sensor P/N 56.03.003 may be mounted a maximum of one time, the sensing element of the NOX sensor P/N 56.03.002 a maximum of two times. The electrical connection to the evaluation unit of both NOX sensors may be established and disconnected a maximum of 20 times. After that, proper functioning of the sensor can no longer be guaranteed. |
