If an ID is defined, for example as A, type the following:
OPEN A
If an ID is defined but forgotten, type the following:
OPEN *
NOTE
The ID can be alphanumeric.
An ID is not needed if the device type LT is included in the OPEN
command. This device type can be used when there is only one LT31 on
the line. This command is similar to the OPEN * command with the
exception that it only opens the LT31 command mode and not the other
possible sensors on the line. The following is an example of the
command.
OPEN LT
If there are other sensors on the line with the same ID, the command
mode of LT31can be opened by including the device type LT with the
ID. This command is similar to the OPEN ID command with the
exception that it only opens the LT31 command mode and not the other
sensors on the line with the same ID. If an ID is defined, for example as
1, type the following:
OPEN LT 1
The LT31 sensor with the ID 1 answers as follows:
LT31-1 LINE OPENED FOR OPERATOR COMMANDS
0>
If no input is given within 10 minutes (default), LT31 closes the line
automatically and gives the following answer:
LT31-1 LINE CLOSED
The user can select the time-out time.
Also, if LT31 receives an OPEN command targeted to another device
while in the command mode, the line for the first opened device will be
closed (the CLOSE command executed).
