the system room can suffocate or be poisoned. After mounting the sensors,
check the tightness of the exhaust pipe.
Risk of burning!
There is a risk of burns when touching the sensing elements of the NOXsen-
sor and the thermocouples because the sensing elements become hot dur-
ing operation. Therefore, note the following points:
–Install the sensing elements on the exhaust pipe at suitable locations
at which people at the plant cannot be burned by them, or install an ap-
propriate protection around the sensing elements that prevents contact
with them.
–The sensing elements must have cooled down sufficiently after switch-
ing off or disconnecting the power supply before you can touch the
sensing elements again.
Risk of destruction and injury!
The EasyNOₓis an electrically operated device, and there is the risk of elec-
trostatic discharges. Therefore, never operate the device without the appro-
priate grounding, to prevent injuries and damage.

2 Safety Instructions

burn engines in industrial environments. The measurement data is provided by a connected CAN
bus/NOXsensor module. Up to two thermocouples can be connected to the CAN bus/NOXsensor
module and are additionally used to measure the exhaust gas temperature near the catalytic
converter and to detect the dew point for the NOXsensor of the CAN bus/NOXsensor module. The
EasyNOₓcan be connected to up to two CAN bus/NOXsensor modules via the CAN bus interface
CAN2 and thus monitor up to two engines.
The optionally available I/O communication module provides the EasyNOₓwith analog and bina-
ry inputs and outputs to which, depending on the application, various functions can be assigned
and which in this way enable communication with a master control. Up to two I/O communica-
tion modules can be connected to the EasyNOₓvia the CAN bus interface CAN1.
Additionally, the EasyNOₓcan start a device that is not directly supported by it, but to which it is
connected via the CAN bus interface CAN1, and monitor its connection status.
The NOXmonitor and the I/O communication module are fully configurable via the EasyNOₓ. A
USB port allows recorded data and reports to be saved to a USB flash drive. Simultaneously, the
EasyNOₓcan integrate up to two NOXmonitors and up to two I/O communication modules.
