Siemens SIRIUS 3RK3 - Displays on the 3 RK3 Advanced Central Unit

7.3.2.2 Displays on the 3RK3 Advanced central unit
LED Display Explanation
DEVICE o󹪜 No voltage, undervoltage, overvoltage
green Device OK, user program in safety mode
green 󹪞ashing
0.5 Hz (ratio 1:1)
System power-up
󹪞ickering green Device OK, user program in test mode
yellow User program stopped (con󹪝guring mode; user program not released; no
user program)
yellow 󹪞ashing
0.5 Hz (ratio 1:1)
Factory settings restored
󹪞ickering yellow See Chapter "Restoring factory settings (Page 347)"
red System stop (e.g. wiring error)
The system stop can only be exited by means of a restart after switching
the power supply o󹪜 and on. If the fault is still present after the system
has restarted, you must replace the 3RK3 central unit.
red 󹪞ashing
0.5 Hz (ratio 1:1)
Error in con󹪝guration
(e.g. memory module removed during operation)
󹪞ickering red See Chapter "Restoring factory settings (Page 347)"
AS-i o󹪜 AS-i bus OK, code table complete
red AS-i bus OK, but code sequence error
red 󹪞ashing
0.5 Hz (ratio 1:1)
AS-i bus not OK, code table either missing or incomplete; TARGET ≠ AC‐
TUAL AS-i con󹪝guration
TEACH o󹪜 Code sequences complete
󹪞ashing yellow Teaching of code sequences in progress
yellow Teaching of code sequences successfully completed, code sequence ta‐
bles can now be applied
SF o󹪜 No group error
red Group fault
1)
that requires acknowledgment
(wiring, communication, parameterization or con󹪝guration error)
red 󹪞ashing
0.5 Hz (ratio 1:1)
Self-acknowledging group fault (logic error)
(e.g. discrepancy time violation, violation of a signal sequence)
IN1, IN2,
IN3, IN4,
IN5, IN6,
IN7, IN8
o󹪜 Input signal not present
green Input signal present
green 󹪞ashing
(1.75 s
on / 0.25 s o󹪜)
Error detected (cross-circuit at input / wirebreak / short-circuit to power
cable / discrepancy error / feedback circuit error / sequence error / error
during startup test)
Input signal present
green 󹪞ashing
(0.75 s
on / 1.25 s o󹪜)
Error detected (cross-circuit at input / wirebreak / short-circuit to power
cable / discrepancy error / feedback circuit error / sequence error / error
during startup test)
Input signal not present
Q1, Q2 o󹪜 Output signal not present
green Output signal present
