LOGGING
Events that can be logged in the UD10 include:
•Calibration(Date,timeandsuccessY/Narelogged
for detectors that do not provide their own calibration
logging capabilities.)
Faults that are logged in the UD10 include:
•Detectorfault
•Lowpower
•Generalfault
Alarms that are logged in the UD10 for gas detector inputs
include:
•Highgasalarm
•Lowgasalarm
•Auxalarm.
The UD10 has its own battery backed real time clock
(RTC) and its own event logs. The RTC in the UD10
can be set from the UD10 display, Modbus or HART
interfaces. The RTC in the gas detector (any HART
detector having an RTC) can be set independently
using the UD10 menu, or by using the synchronize
command, which will set the detector RTC to the same
time as the UD10 RTC. See Figure 3.
The UD10 can display the detector event and
calibration logs (if available). The UD10 has its own
1,000-entry event log available under the Display
Status->History->Event Log menu.
UD10 event logs can be read from the HART interface
or the Modbus interface.
Detector calibration and event logs can also be read
from the detector HART interface (where available).
