Measuring protection
Positive/negative
edge
1)
Activate measuring protection.
As long as the measuring protection is active, no other user actions on the
device are possible. This especially includes changes
to the configuration as
well as initialization of calibration via a digital input or via a bus interface.
A cyclical AutoCal that has already been configured is still executed, how-
ever because no user actions are necessary for this.
The measuring protection is only set if the following requirements are met:
• The device is in the "Measurement" operating mode.
• The inputs/outputs are not currently tested, for example, during the
commissioning/checking of communication with the control system:
→ Menu [3.11] Maintenance and diagnostics > Test
• The device is not in the "Function check" operating mode.
• No user is logged on.
The measuring protection is set with a delay under the following conditions:
• As long as function check is active
• As long as the operating mode is not "Measurement"
• As long as an already started calibration is still running (including expira-
tion of the sample gas purging time)
• If a calibration was triggered by a digital input, until the end of the cali-
bration or until the trigger is discarded.
• If an AutoCal/AutoVal is pending and its execution is delayed
• As long as an AutoCal/AutoVal is running, including sample gas inter-
mediate operation
