Commissioning - Siemens SIRIUS 3SK1 Equipment Manual

Commissioning

Note
Since commissioning of the 3SK1 safety relays is an important, safety-related step, it must be
carried out by qualified personnel.
Hazardous voltage
Can cause death, serious injury, or property damage.
Carry out function test of the plant.
To guarantee the safety of the system, a full functional test must be carried out and successfully
concluded following commissioning.
Commissioning 3SK1 safety relays
3SK1 safety relays are commissioned by applying the operating voltage.
After the supply voltage has been applied, all LEDs show a green light for about 1 s (lamp test).
The LEDs then go out for approx. 0.5 s. The device configuration is then displayed on the
configuration LEDs for approx. 3 s.
If no configuration change (DIP, PAR, potentiometer, input expansion, output expansion) has
been detected, the device changes automatically to safety mode and is ready for operation.
However, if the device detects a deviation of the set parameters from the saved configuration,
it remains in safe configuration mode until the new configuration is accepted by pressing the SET/
RESET button.
Note
Observe the following during commissioning:
The cascading input must be bypassed (24 V DC) if it is not to be used.
Monitoring of the feedback circuits is not optional.
