AC500 system supply (terminals L+, M)

As soon as the CPU power supply is higher than 19.2 V DC, the power supply detection is activated and the CPU is started. When during operation the power supply is going down to lower than 19.2 V DC for more than 10 ms, the CPU is switched to safety mode (see System Technology of the CPUs).

A warm restart of the CPU only occurs by switching the power supply off and on again. Ssee also the description of the function modes of the CPU in the “AC500 System Technology” chapters.

S500 system supply is provided through the FBP plug. AC500 or S500 process power supply through terminals UP and ZP.
