The default setting for all warnings and alarms is OFF. To set and enable:
1. In the Online menu, press 3 Device Setup.
2. In the Device Setup menu, press 2 Diagnostics/Service.
3. In the Diagnostics/Service menu, press 1 Diagnosis
4. In the Diagnosis menu, press 3 Warnings/Alarms. Refer to the Online Configuration Map in
Appendix A and to the HART Communicator’s help screens.
6.4.19.1 Operating Hours Counter
Two operating hours counters with non-volatile memories are provided for the electronics and the sensor.
These counters are not re-settable. If power is removed and later reapplied, the counters begin counting
from the previous time. To read the operating hours counters:
1. In the Online menu, press 3 Device Setup
2. In the Device Setup menu, press 2 Diagnosis/Service
3. In the Diagnosis/Service menu, press1 Diagnosis
4. In the Diagnosis menu, press 2 Operating Hours
5. In the Operating Hours menu, press 1 Operating Hours Electronics or 2 Operating Hours Sensor. The
total operating hours will be displayed.
6.4.19.2 Calibration Timer and Service Timer
A two-stage time can be set to ensure regular calibration of the electronics and servicing of the
transmitter. A calibration or service warning appears after the first time expires. On expiration of a second
time, set as a time difference, a diagnostic alarm is signaled and a fault current is output.
A warning or alarm must be acknowledged before work can be performed on the transmitter. Timers can
then be reset and switched off temporarily.
For operating/acknowledging warnings and alarms in the HART Communicator, the following applies:
As long as the warning/alarm limit has not been reached:
•
“Reset” resets the timer and begins again with the counter at 0. Monitoring is still active.
•
“Acknowledge” has no effect, the timer continues running and the monitoring is still active.
•
“Reset and deactivate” stops the timer, resets it, and deactivates the monitoring.
When the warning/alarm limit has been reached:
•
“Acknowledge” resets the warning/alarm message but the timer continues to run. In this state, no new
alarm or warning is possible since the time limits will still have to be exceeded.
•
“Reset” resets the warning/alarm message the timer. At the same time, the alarm or warning is
acknowledged. The timer runs again immediately from zero and will respond again when the
warning/alarm limit is exceeded. The next calibration interval is therefore immediately activated.
•
“Reset and ActivateW/A” resets the warning/alarm message and resets and deactivated the timer.
