Functions
User-configurable – can be activated by one or more of the
following signals:
• Process alarm 1, 2, 3, 4
• Calibration in progress
• Calibration failed
• Out of test gas 1, 2
• Test gas 1 valve control
• Test gas 2 valve control
• Failure diagnostic
• Out-of-specification diagnostic
• Maintenance required diagnostic
• Function check diagnostic
*For driving internal automatic calibration (AutoCal) probes or can be used
to drive external calibration units on remote transmitters only.
