Diagnostics / ...Alarm Simulation
Manual simulation of alarms / error messages.
The simulated alarm is selected by setting the parameter to the corresponding error.
See also chapter Diagnosis / error messages on page 128.
The following error messages can be simulated:
Off, Flow Mass Reached, Flow Volume Reached, Simulation Alarm, Flowrate to Zero, Maint. Cycle Time, Totalizer Stop, Totalizer Reset, Totalizer Rollover, Dev. not
calibrated, NV defect on FEB, NV data defect, FEB not detected, FEB comm. error, Incompatible FEB, NV defect on MB, DO 41/42 Saturated, CO 31/32 Saturated,

Description
Activate the monitoring function for current output 31 / 32.
Activate the monitoring function for current output 31 / 32.
The transmitter measures the actual current and compares the measured value to the set point for the current output. If
the measured value deviates from the set point by more than ±2 %, the current output on the alarm current of 3.3 mA is set
and the 'Communicat. card not responding' error message is generated.
Factory setting: Off.
Selection of submenu '...Alarm Reset Option' using
Manually resetting the 'Communicat. card not responding' error message using
Automatic reset of the 'Communicat. card not responding' error message.
• Off: The error is permanently saved and must be reset manually. After the reset, the current output 31 / 32 is retested.
• On: The error is automatically reset after 10 minutes. After the reset, the current output 31 / 32 is retested.
Factory setting: On.
Behavior in the case of an open current output 31 / 32 (interruption of the current loop).
• Off: If the current loop is interrupted, the 'Communicat. card not responding' is generated. The reset of the error then
depends on the setting of the 'Auto. Reset 10 min' parameter.
• On: If the current loop is closed again, the error will be automatically reset.
Factory setting: On.
