) The state of the LEDs corresponds to the logic state of the output. In case
of missing or low process supply voltage UP3 or UP4, the signal on the output
terminal is off even though the LED is on.
Technical data
The system data of AC500 and S500
Chapter 2.6.1 “System data AC500” on page 971
are
applicable to the standard version.
The system data of AC500-XC
Chapter 2.7.1 “System data AC500-XC” on page 1023
applicable to the XC version.
Only additional details are therefore documented below.
The technical data are also applicable to the XC version.
