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 131.
The following error messages can be simulated:
Off, Mass flowrate exceeds limits., Volume flowrate exceeds limits., Simulation is on. Simulating process/output value. , Flowrate to zero, Maintenance interval is
reached, All totalizer stopp., Totalizer reset. Reset of one or more Totalizer, Display value is <1600h at Qmax., Device not calibrated., Sensor memory defective., NV

Description
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 'CO 31/32 readback current deviates' error message is generated.
Factory setting: Off.
Selection of submenu '...Alarm Reset Option' using
Manually resetting the 'CO 31/32 readback current deviates' error message using
Automatic reset of the 'CO 31/32 readback current deviates' 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 'CO 31/32 readback current deviates' 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.
