Characterize loop
Loop characterization must be initiated when the level detector is first installed or when
electrical loop characteristics have been intentionally altered. Examples include a modified
power supply level or loop resistance of the system, changing the terminal block on the
level detector, or adding a Smart Wireless THUM to the level detector.
Note
Power Advisory is not recommended for a level detector operating in multi-drop mode.
Power Advisory action
When the voltage deviation exceeds the set limit, four possible actions can be configured
and can be set to “Latched” or “Unlatched”.
When the alert or alarm is unlatched, the alert or alarm will disappear if voltage deviation
returns to a normal level. A latched alarm or alert will not disappear when the voltage
deviation returns to normal levels. This requires the user to acknowledge and clear the alert
or alarm.
The four Power Advisory diagnostic actions are:
None
Alert latched
Alarm unlatched
Alert unlatched
Note
When messages about the loop appear, take appropriate safe action.
