Mounting the Sensing Element of NOₓ Sensor P/N 56.03.003

 

Risk of suffocation! Risk of poisoning!

Leaks in the exhaust pipe can cause exhaust gases to escape and people in the system room can suffocate or be poisoned. After mounting the sensors, check the tightness of the exhaust pipe.

   

Operational safety!

To safely mount the NOX sensor, be sure to observe the following:

  • To protect the NOX sensor and yourself, wear ESD-compliant work gloves. To protect the NOX sensor against electrostatic discharge, also comply with IEC 61340-5-1 and IEC TR 61340-5-2 in their respective valid versions.
  • Under no circumstances touch the probe of the sensing element while mounting.

   

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 may be mounted a maximum of one time. The electrical connection to the NOX sensor's evaluation unit may be established and disconnected a maximum of 20 times. After that, proper functioning of the sensor can no longer be guaranteed.

   

SCR catalytic converter: no monitoring in accordance with VDMA 6299:2019-09

The NOX monitor of the EasyNOₓ does not evaluate the dosing release of the urea solution in an SCR catalytic converter. Thus, the NOX monitor of the EasyNOₓ is not suited for monitoring SCR catalytic converters in accordance with the standard sheet VDMA 6299:2019-09.

 

The following sections describe the mounting of the sensing element of the NOX sensor from the CAN bus/NOX sensor module.
