Switching the System On and Off
1.11.1
Switching On
Before switching the system on, all system elements must be connected to a power supply.
Switching on takes place by connecting the voltage, as for example by switching on a minia-
ture circuit breaker. The system starts up automatically (startup after power-up).
The entire system is operational (without consideration of the error display), as soon as all
system elements have concluded the startup (refer to section 5.2,
plays). This is also applicable analogously, if only parts of the system are switched off and
switched on again.
1.11.2
Switching Off
The switching off of the system takes place by disconnecting the voltage on all system parts.
With redundant power supply, pay attention to entire loss of voltage.
Caution
The switching off of the master control element during writing operations to the flash card (load firmware,
load parameters) is to be absolutely avoided, since the data on the flash card could be destroyed as a
result.
