Siemens SIRIUS 3RK3 - Protective Door

Message Meaning LED response
SF-LED on central
unit
Input LEDs on central unit
or expansion module
Start signal duration invalid Only with start type "Monitored start":
The start signal time monitoring ele‐
ment detected a violation.
‑ ‑
Start condition not ful󹪝lled is set if:
• A sensor test was not executed in
the case of an active startup test
function
• A discrepancy condition violation is
present
• The value "1" is not present simul‐
taneously at all available (parame‐
terized) function inputs (IN1, ...)
• A cross-circuit is present in the case
of cross-circuit monitoring

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 actuated at least once.
‑ The IN LEDs of the sensor are 󹪞ash‐
ing green.
Sequence condition not
ful󹪝lled
The sequence condition was not ful‐
󹪝lled in accordance with the parame‐
ter assignment.
󹪞ashes red Basic: The IN LEDs of the sensor are
󹪞ashing green.
Advanced/ASIsafe: The sensor that
triggered the sequence violation is
󹪞ashing.
Discrepancy condition
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
monitored 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 󹪞ash‐
ing green.
Safety sensor triggered The safety sensor has been actuated.
This message is automatically reset if
the value "1" is present for all function
inputs monitored (set as part of con‐
󹪝guring).
‑ The IN LEDs of the sensor are o󹪜.
The IN2-LED is green on input type
NCNO.
