Page 273 This is the zero value for the remote set point function specified by option parameter 20.7. Option 21.9 – Remote Set point 1 span (20 mA) value (0 - 999 / 00.0 - 99.9 / 0.00 - 9.99) 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–49...
Page 274 22.6 and 22.7 represent a deviation (i.e., offset) from the set point 1 control value. This means that if the set point control value is changed, the limits are automatically changed correspondingly. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–50 © 2025 Fireye...
Page 275 This defines the address of the first Lag to be selected if this controller is the Lead. Option 24.2 - 2nd Lag communications address (0 – 15) This defines the address of the second Lag to be selected if this controller is the Lead. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–51...
Page 276 For example, a value of 100 may be better suited for a minimum Gas Flow to ensure best resolution. Option 28.2 – Analog input 1 span value (20 mA input) Set this option to the value that a 20mA input current will represent. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–52 © 2025 Fireye...
Page 277 Option 28.8 – Analog input 3 span value (20 mA input) Set this option to the value that a 20mA input current will represent. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–53 © 2025 Fireye...
Page 278 Set this option to the value that a 20mA output will represent. For example, value of 200 may be better suited for a maximum Flue Gas Temperature to ensure best resolution. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–54...
Page 279 Set this option to the value that a 4mA output will represent. Often this will be zero, but non-zero values can be used. Option 29.8 – span value (20 mA output) Set this option to the value that a 20mA output will represent. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–55 © 2025 Fireye...

Page 281 As soon as the measured oxygen reading begins to change, stop the timer. Set the option parameter to the recorded timer value in seconds. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–57...
Page 282 High Fire, or Low Fire – depending on trim direction. The burner always modulates to the desired modulation rate, which may limit the system’s ability to maintain the desired oxygen value. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–58 © 2025 Fireye...
Page 283 When a second oxygen monitoring system is used, the oxygen can be considered fail-safe, and the trim limits can be set up to 50% instead of 25%, provided the maximum time between probe calibrations does not exceed six months. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–59...
Page 284 The accuracy of the calculated efficiency and the ‘Automatic Trim commissioning’ procedure will be adversely affected by this. It maybe that these functions should not be used, in which case these values should be entered as zero. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–60...
Page 285 If the burner is firing, you can only adjust the option parameter that relates to the selected profile. If the burner is not firing, you can adjust the low alarm value for any profile selection. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–61...
Page 286 Options 38.1 to 38.4 - Oxygen low alarm values at Low Fire (0.0 – 99.9%) Options 39.1 to 39.4 - Oxygen low alarm values at High Fire (0.0 – 99.9%) 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–62...
Page 287 CANbus, as for option parameter 30.0. In applications where CO monitoring and trim are a requirement, enter the serial number for the oxygen probe controller entered in option 30.0. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–63 © 2025 Fireye...
Page 288 Option 42.6 – Second oxygen probe calibration enable (0 to 2) This option is identical to option 30.6, except that it relates to the second oxygen probe. Note, the calibration gas concentration used must be as entered in option parameter 30.3. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–64...
Page 289 Option 42.2 – CO trim gain (0 – 250) CO trim gain sets the rate at which the CO trim acts – modifies the O2 Set point. Fireye recommends setting this parameter to a value of 10% initially, and then adjusting to suit the application response.
Page 290 Where a CANbus gas pressure sensor is used for the VPS and operating limits select the serial number of the device from those offered, in a similar way to selecting actuator serial numbers for Option 3.x. Options 11.x set the span and VPS test characteristics. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–66...
Page 291 This option clears the current the fault history. Set the option parameter to 1 then press RUN then ENTER. The controller will erase the fault history and return to Run mode. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–67...
Page 292 IMPORTANT: If you select 5, all profile set points will be deleted and all option parameters will reset to default values. The controller will be initialized to the factory default settings. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4 7–68...
Page 293 If the non-standard passcode is forgotten then a ‘master passcode’ will need to be obtained, based on the unit serial number. This can be obtained using an on-line passcode system maintained by Fireye. 7 NX6100 Fireye- Appendix V1pt4D Firmware issue 1.4...
