Description
Cd38 will display the current supply recorder sensor (SRS) reading for units con-
figured for four probes. If the unit is configured with a DataCORDER, Cd38 will
display "-----." If the DataCORDER suffers a failure, (AL55) Cd38 will display the
supply recorder sensor reading.
Cd39 will display the current return recorder sensor (RRS) reading for units config-
ured for four probes. If the unit is configured with a DataCORDER, Cd39 will display
"-----." If the DataCORDER suffers a failure, (AL55) Cd39 will display the return re-
corder sensor reading.
If a valid container id exists, the default display for Cd40 will be "cd40_XXXXX"
where "XXXXX" is the 5th character through the 9th character of the container id.
Pressing the ENTER key on Cd40 will display "id_YYYYYYY" where "YYYYYYY"
is the 5th character to the 11th character of the container id.
If no valid container id exists or the container id is blank, the default display will have
Cd40 on the left display and the right display will alternate between "_nEEd" and
"___id". Pressing the ENTER key while on Cd40 in the state will prompt the Set Id
Interface.
On start up if the container id is not valid, Cd40 will be brought up on the display for
the first minute of power up. This can be left by either entering a container id or leav-
ing the code select normally.
Cd40 is configured at commissioning to read a valid container identification num-
ber. The reading will not display alpha characters; only the numeric portion of the
number will display.
