Siemens SIRIUS 3RK3 - Protective Door with Lock

Message Meaning LED response
SF-LED on central
unit
Input LEDs on central unit or ex‐
pansion module
Cross-circuit at input x A cross-circuit was detected at input x. Red The IN LEDs of the sensor are 󹪞ash‐
ing green.
Start signal duration in‐
valid
Only with start type "Monitored start":
The start signal time monitoring ele‐
ment detected a violation.
‑ ‑
Start condition not ful󹪝l‐
led
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 signal sequence violation is
present
• A cross-circuit is present in the
case of cross-circuit monitoring

The table below lists all the messages and corresponding LED responses to the "Protective Door
with Lock" function element.
Message Meaning LED response
SF-LED on cen‐
tral unit
Input LEDs on central unit or
expansion 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.
‑ The IN LEDs of the sensor are
󹪞ashing green.
Sequence condition not ful󹪝l‐
led
The sequence condition was not ful󹪝lled in
accordance with the parameter assign‐
ment.
󹪞ashes red 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 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.
