Code 30
Note: Error in configuration memory. Please
verify user defined parameters and check the
back-up battery.
This error message is displayed when the system is switched on
and the buffer battery power for the settings and the real-time
clock is too low. Please replace the buffer battery. Then it is
necessary to reset the clock (see chapter 5.7.4). The settings
(setpoints, etc.) - except for the modifications made in the last
operating phase - are automatically reloaded from the second
read-only memory so that they are available even after a failure of
the buffer battery. Nevertheless, it is recommended to check the
settings.
