Remark/cause
Total function check: signaling of function check at device level
Function check at module level: signaling of function check for analyzer
modules 1 or 2
No function assignment
Signaling of limit violation of limit 1 or 2. The measured value violates
the corresponding limit
Signaling of "Calibration" operating state at module level
Total function check: signaling of "Calibration" operating state at device
level
Signaling contact: AutoCal signal contact, pulse 1000 ms
Signaling of active measuring range
Switching on of sample gas 1
Switching on of sample gas 2
Switchover of the process tag
Switching on zero gas for calibration
Switch external sample gas pump (on/off)
Signaling of device status "Fault"
Synchronization of AutoCal sequences between several devices
Signaling of device status "Maintenance alarm"
Signaling of device status "Maintenance demanded"
Signaling of device status "Maintenance required"
Active level Remark/cause
Enabled Digital outputs 21 or 24.
The relay serves as status relay that signals an exit from safe
Passive
measurement.
Passive
Passive Digital outputs 22 or 25.
The relay signals whether the module is in "Function check" mode.
Enabled
Passive Digital outputs 23 or 26.
The relay is used in analyzer modules to signal the fault status.
