NOTICE
Communication failure of PSB-S modules in case of polarity reversal
The polarity reversal of the 48 V connectors of a PSB-S module may result in the
communication failure of several PSB S modules during travel.
Ensure the correct polarity.
Refer to the "EMS400S Plant controller for Electric Monorail Systems" system manual
and the "EMS400S Diagnostics Unit" operating instructions, see Preface (Page 3).
Malfunction or damage in case of polarity reversal on the PSB-C module
The polarity reversal of the 24 V connectors of a PSB-C module may result in equalizing
currents and equalizing voltages at the analog output of the PSB C module. The result
may be malfunctions or damage of the device connected to the analog output.
Ensure the correct polarity.
Additional information is available in the "S7-1200 Automation System" system manual.
