TX180 Temperature Transmitter 15
The transmitter is indicating
FAILSAFE
, since no sensor is connected, and the analog output is
indicating greater than 100%, loop current at 23.00mA, which is the standard Failsafe report
condition. Please note that the display / keyboards can be plugged into the transmitter while the
transmitter is powered up. There is no need to disconnect power before plugging the LI-1 or LI-2 into
the TX180.
Press the key marked
NEXT
. The display starts to alternate asking if the user wishes to return to the
Operate Mode?
To activate the
NEXT
and
ENTER
; keys a slow, deliberate push of the key is required. This prevents
any casual, inadvertent activation of the transmitter into one of the configuration modes.
The answer would be “No”, therefore, press the
NEXT
key. This will enter you into the
DISPLAY
MODE
configuration menu. If you wish to answer a question “Yes”, press the
ENTER
key. A flow
chart summarizing the operation of the
DISPLAY MODE
appears at the end of this manual.
Note that when more than seven characters are required to describe a function, the display keeps
sequencing through two or more screens or may use common abbreviations. In this manual, the
sequencing of the display is indicated by placing the two or more parts of the message adjacently.
With some functions, the LI-2 display indicates a numeric value and unit of measurement on the top
line of the display in addition to the message on the lower display line.
