In NO
X
monitoring modes Off and Recording Only , normal operation detection is dis-
abled. In the NO
X
monitoring mode Start/Stop via CANopen , the NO
X
monitor receives
the normal operation release from the master control.
– K
Enter the NO
2
/NO
X
ratio of the exhaust gas from your system. The NO
2
/NO
X
ratio must be de-
termined at the mounting position of the NO
X
sensor's sensing element before start-up of
NO
X
monitoring and each time the NO
X
sensor is replaced. More information on this is avail-
able in the section Determining the NO
2
/NO
ₓ
Ratio on page 55.
– KNO
2
Enter the factor for the corrective calculation of the NO
X
sensor's NO
2
sensitivity. For the cor-
rection factor, refer to the entry NO
2
Gain in the NO
X
Sensor view (see section Sensor on
page 117).
– Level Limit
Enter the daily average of the NO
X
concentration, which must not be exceeded under any cir-
cumstances. To use the NO
X
monitoring of the EasyNO
ₓ
in accordance with standard sheet
VDMA 6299:2019-09, enter here the daily average at which an alarm should be triggered. If
the daily average exceeds the level limit at the end of a day, the detected normal operation
hours are added to the failure hour counter of the ongoing calendar year. The change of day
is firmly preset to 0:00 hrs Central European Time (CET) or UTC+1.
– Level Warning
Below the configured Level Limit , specify a daily average of the NO
X
concentration above
which the EasyNO
ₓ
will issue a warning. The Level Warning daily average serves to indicate
that the daily average is approaching the configured level limit. As a warning threshold, you
can specify your currently valid plant-specific limit value.
– Time Limit
For the failure hour counter of the NO
X
monitor, specify a time threshold that the NO
X
con-
centration may exceed the configured level limit as a maximum within one calendar year. If
this time threshold is exceeded, the EasyNO
ₓ
indicates this in the NO
X
Monitoring view in the
failure hour counter Alm via a red status display.
– Time Warning
For the failure hour counter of the NO
X
monitor, specify a warning threshold to indicate that
the failure hour counter is approaching the configured Time Limit . If this warning threshold
is exceeded, the EasyNO
ₓ
indicates this in the NO
X
Monitoring view in the failure hour
counter Alm via a yellow status display.
– Name
Enter a custom name for the engine to be monitored. This name is displayed in the title area
in all views of the respective NO
X
monitor.
– Serial Number
Enter the serial number of the engine to be monitored. This field is mandatory.
