6-6. Function Check with Control Terminal
There are two types of display modes for operation check from control terminal, which can be selected
depending upon the purpose. The first type of display mode is provided by the system status display and
the other is provided by the “W” menu on the menu display.
The system status display shows result of self diagnostics that is performed automatically by the primary
station when the main power of the system is turned on. It also shows error messages that are issued by
the respective stations on the S-BUS data link in real time, enabling to use the system status display as the
monitor of system operation during system run.
To check the old system status, call the menu item [W: SYSTEM STATUS LOG].
This menu takes out only the system status from the memory, and displays error messages, corresponding
station and time of occurrence.

As the control terminal constantly checks the errors of the system, and is capable of recording/displaying
these, it is extremely effective for monitoring the operations of the system. Therefore, it is recommended
to connect this control terminal after completing initial settings.

When the power of the primary station is turned on, the results of the self-diagnosis of the primary station
and the ROM checksum value, will be displayed as shown in the figure below.
If the result of the self-diagnosis is normal, “OK” will be displayed for this item. If errors have been
detected, the corresponding item will be the reversal characters.
