Generally, messages are performed via LED, error and alarm output, PC program, or via the
bus system. It can be adjusted via the PC program if a message should be read out via the
error or alarm output.

Further Messages
An LED is also installed at each of the 10 SYT outputs for the purpose of network load
optimization, from which one can recognize if the output is set or not.
7.5.4
Fuse Triggering
The Thyro Power Manager possesses an internally built-in fuse (T 1A 250V). Yet, this only
serves the purpose for the internal protection of electronics and is not for power line security.
If this fuse responds, the green power LED H100 goes out, and the Unit does not operate
any more.
