Setting protection
The lock to prevent rewriting can be set to each category of
the setting values.
Since this setting change is sent to the TM201 immediately,
there are no buttons like "Set".
<Setting value>
Self check
"Self Check" button
Self-check is a function to check the memory of the TM201 main unit
automatically and to detect errors.
It is also a function that performs checksum of software, operation check
of NOVRAM and RAM, and check of lamp lighting. This function does
not diagnose the analog circuit.
When the "Self Check" button is clicked, operation of the TM201 is
checked, and the software version of the TM201, checksum and results
are displayed.
During self-check, the STATUS (green) lamp and ALM (red) lamp all light off → light on (green)
→ light on (red) → all light on. Once the self-check is complete, the display returns to normal.
If the check is complete normally, "PASS" is displayed in the result.
If an error is detected in the TM201, "NGXX" is displayed in the result. (XX represents a 2-digit
number.)
● If "NGXX" is displayed, it may be a sign of failure. (XX represents a 2-digit number.)
