Siemens SIRIUS 3RK3 - Display Philosphy; Error Management

7.2.1 Display philosphy
In error management, the following display concept applies:
• Errors requiring acknowledgment are displayed by a red SF LED.
WARNING
System Restart After Fault Acknowledgment/Restart
Can Cause Death, Serious Injury, or Damage to Property.
After fault acknowledgment/restart, the system immediately resumes operation with the
values speci󹪝ed by the control, and outputs are activated if the power-on condition is
ful󹪝lled.
Take appropriate measures (e.g. start button with monitored starting) to prevent
unintentional restarting and to ensure a de󹪝ned start of the system.
• Self-acknowledging errors are displayed by a red 󹪞ashing SF LED.
• If more than one error is present at the same time, red has priority over red 󹪞ashing.
• The LEDs of the real inputs on the MSS 3RK3 to which the error refers also indicate the error
by a green 󹪞ashing LED.
7.2.2 Error management
Error categories
Error management makes a distinction between 󹪝ve di󹪜erent error categories:
• Device error
• System error
• Logic or wiring error
• Parameterization or con󹪝guration error
• Handshake error
Device error
A device error causes the system to stop. Communication between the modules is not possible.
The cause of such an error is either internal system error or a defective 3RK3 central unit.
