After modifying an existing O2 trim profile, use Option 30.8 to reset the feed forward function.
See option 30.8 for details.
Option 30.0 – Oxygen probe interface serial number LV3
Each CANbus device connected to the system has a unique serial number allocated to it during
production testing. This number cannot be changed and is used to uniquely identify each device.
When the system is in commissioning mode the serial number of all the connected devices is read by the
NX6100 and displayed as a ‘list’ to allow the selection of the relevant serial number unit to be made.
Scrolling the list in an upward direction will scroll through all oxygen probe interface options available until
‘0, nothing’ is displayed. Enter this value to disconnect the specified device from any hardware.
Scrolling the list in a downward direction will stop when the currently selected item is displayed, and the
value will stop flashing.
The display will show type information for each device present (such as ‘O2 probe’), but the
commissioning engineer should be aware of which serial number device is being used for which function.
Option 30.1 - Oxygen probe calibration offset value (0 – 999) LV3
This option parameter is only available if option 30.0 is non-zero.
This option parameter must be set to the calibration offset value that is specified with the Fireye probe
supplied.
When using another manufacturer’s O2 probe with a 4-20mA signal for O2 value, enter the O2 value for
4.0mA in this option parameter. Example 0% O2 = 000.
Option 30.2 - Oxygen probe calibration gain value
(0 – 999)
LV3
This option parameter is only available if option 30.0 is non-zero.
This option parameter must be set to the calibration gain value that is specified with the Fireye probe
supplied.
When using another manufacturer’s O2 probe with a 4-20mA signal for the O2 value, enter the O2 value
for 20.0mA in this option parameter. Example 21% O2 = 210.
NOTE: If the value of 30.1 and 30.2 are both below 300, the NX6100 will utilize the analog input on
the NXO2TRIM terminals PG6(+)PG5(-)to determine the O2 signal.
Option 30.3 - Oxygen probe calibration gas concentration (0.00 – 9.99%) LV3
This option parameter is only available if option 30.0 is non-zero.
This option parameter must be set to the percentage oxygen concentration of the calibration gas used if
the probe is to be calibrated using a reference gas (see option parameter 30.6). The range of this
parameter is 0.00 - 9.99%.
