View transmitter status using the status LED
The status LED is located on the user interface module of the transmitter.
Procedure
View the status LED on the user interface module of the transmitter.
• For transmitters with a display, you can view the status LED with the transmitter housing cover in
place.
• For transmitters without a display, the transmitter housing cover must be removed to view the status
LED.
If the transmitter is in a hazardous area, do not remove the housing cover while power is
supplied to the unit. Removing the housing cover while power is supplied to the unit
could cause an explosion. To view transmitter status in a hazardous environment, use a
communication method that does not require removing the transmitter housing cover.
To interpret the status LED, see Table 8-1 .

View and acknowledge status alarms
To view and acknowledge status alarms, you can use the transmitter display, ProLink II, or the
Field Communicator.
The transmitter maintains two status flags for a status alarm:
• The first status flag indicates
Active
or
Inactive
.
• The second status flag indicates
Acknowledged
or
Unacknowledged
.
An alarm is
Active
when the transmitter detects that the alarm condition exists. An alarm is
Inactive
when
the transmitter detects that the alarm condition has cleared. When an alarm is posted, it is set to
Unacknowledged
. Operator action is required to change the status from
Unacknowledged
to
Acknowledged
,
whether or not the alarm is still active.
