7.3 Information from the controls in case of a system error
7.3.1 CPU
A system error is triggered by the Siemens system software, e.g. by the detection of an SPS hardware fault.
A system error is signalled by the “SE” LED.
System errors are:
• SPS hardware faults,
• Firmware errors,
• Program errors,
• Parameterising errors,
• Computational errors,
• Time errors,
• Faulty internal memory storage,
• Battery failure or the standby supply is missing while MAINS ON,
• Peripheral error in the internal peripheral functions.
A PG or a PC with the relevant software must be used to read out the diagnostics buffer for precise
determination of the errors.
) There is no alarm message in the display.
If a system error occurs, it can be signalled in one of the following possible ways:
Option 1: The “SE“ and “RUN“ LEDs are alight.
The application program continues to run.
The compressor is not switched off.

LED off
