Table 7.1 Analog sources

7.2.2 Digital output sources

Source name* Description
Alarm 1 (8) State Process alarm state (alarm 1 to 8).
S1 (4) Failure The associated wet-section is in the failed state – see Appendix A, page 72 for possible causes.
S1 (4) Out of Spec. The associated wet-section is out of specification – see Appendix A, page 72 for possible causes.
S1 (4) Maintenance The associated wet-section requires maintenance – see Appendix A, page 72 for possible causes.
S1 (4) Function Check The associated wet-section requires checking – see Appendix A, page 72 for possible causes.
Tx Failure The transmitter is in the failed state – see Appendix A, page 72 for possible causes.
Tx Out of Spec. The transmitter is out of specification – see Appendix A, page 72 for possible causes.
Tx Maintenance The transmitter requires maintenance – see Appendix A, page 72 for possible causes.
Tx Function Check The transmitter requires checking – see Appendix A, page 72 for possible causes.
S1 (4) Cal in Progress A calibration is in progress for the associated wet-section.
S1 (4) Cal Failed The last calibration has failed for the associated wet-section.
Table 7.2 Digital output sources

7.2.3 Digital input sources

Source name* Description
S1 (4) High Std Cal High standard calibrations.
S1 (4) Low Std Cal Low standard calibrations.
S1 (4) 2-Pt Cal Two-point calibrations.
S1 (4) 2-Regen Cal A sensor regeneration sequence is followed automatically by a two-point calibration.
S1 (4) Hold The measured concentration for the associated wet-section can be held via the digital input.
Note. It is recommended that a momentary switch is used to start or abort calibrations and a toggle switch is used for the hold
functionality.
To start a calibration – hold the momentary switch for a minimum of two seconds; when the calibration starts release the switch.
To abort a calibration – hold the momentary switch for a minimum of two seconds; when the calibration aborts release the switch.
