5.2. RESET behaviour
The RESET function differentiates into a start-up function after restoration of voltage = general
reset and a status reset / an alarm reset = internal reset. The latter is triggered via the front-side

with enabled “alarm reset” function.
The following chart provides an overview about the RESET functions and their effect. The timing
behavior can be taken from the SCU installation manual.
