Siemens SIRIUS 3RK3 - LED Response for Various Element Functions; Monitoring Universal

7.3.3 LED response for various element functions
7.3.3.1 Monitoring Universal
The table below lists all the messages and corresponding LED responses to the "Monitoring
Universal" function element.
Message Meaning LED response
SF-LED on central
unit
Input LEDs on central unit or ex‐
pansion module
Startup test required This message is set in a parameterized
startup test on each restart and each time
the substitute value is changed to a real
value until the connected sensor is actu‐
ated at least once. After the sensor has
been operated correctly this message is
automatically reset.
‑ The IN LEDs of the sensor are 󹪞ashing
green.
Sequence condition
not ful󹪝lled
The sequence condition was not ful󹪝lled in
accordance with the parameter assign‐
ment. This message is automatically reset
if the value "0" is detected for all function
inputs monitored.
󹪞ashes red The IN LEDs of the sensor are 󹪞ashing
green.
Discrepancy condi‐
tion violated
is set if:
• After the discrepancy time has
elapsed, the signal states at the inputs
monitored are di󹪜erent
• The signal states of the inputs moni‐
tored had not all previously been reset
simultaneously to the value "0" when
they are set to "1"
󹪞ashes red The IN LEDs of the sensor are 󹪞ashing
green.
Safety sensor trig‐
gered
The safety sensor has been actuated. This
message is automatically reset if the value
"1" is present for all function inputs moni‐
tored (set as part of con󹪝guring).
‑ The IN LEDs of the sensor are o󹪜.
The IN2-LED is green on input type
NCNO.
Cross-circuit at input
x
A cross-circuit was detected at input x. red The IN LEDs of the sensor are 󹪞ashing
green.
