7.6 Cyclic and acyclic data
Power supply system SITOP PSU8600
236 Manual, 09.2018, A5E36758446-5-76
Operating state, output 1 … n (channel1 … n operating state)
The status messages of an output are listed in the table below. The data applies to outputs 1
to n.
0 = ManualOff Output switched off manually (button): The output was manually switched off using the
button on the device. The device can only be switched on manually using the button on the
1 = RemoteOff Output switched off (PROFINET/IE): The output was remotely switched off via
Output switched off (prioritization output 1): The output was switched off during buffering.
3 = OverLoadOff Output switched off (overload): Invalid overload occurred at the output. The output was
4 = ReadyForRestart Output ready for reset (reset): Output is ready to be switched on again after automatic over-
Output switched off (error)
Output switched off (startup)
Output switched on (normal operation)
8 = OverLoad Output in overload operation: The output current is above the specified response threshold,
but still within the permissible overload profile.
9 = Limit Output current limited to the response threshold: The output is in the overload mode. The
output current is limited to the configured response threshold.
10 = OverloadWithDerating
Output in overload operation (system overload)
Output current limited (system overload)
Output switched off as the UPS8600 is being charged
Operating states SITOP BUF8600
Operating state of the buffer module (buffer operating state)
Buffer component is in the "Off" operating state.
Buffer component is powering up.
2 = Full Complete buffer readiness: The energy storage device of the buffer component is fully
charged (normal operation).
3 = Buffering The buffer component is operating in the buffer mode: The power supply system is supplied
via the buffer component(s).
4 = ErrorOff Shutdown after error: A fault/error has occurred when operating the buffer component. The
buffer component is not operational and must be restarted by switching off the supply volt-
age and switching it on again.
6 = NotFully
Ready for buffer operation as the energy storage device of the buffer component has been
sufficiently charged, but has not been fully charged.
7 = NotFully
Not ready for buffering as the energy storage device of the buffer module has not been
sufficiently charged and is presently being charged.
Buffer component is deactivated.
Firmware is being updated
