Commissioning - Siemens SIRIUS 3SK1 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 ensure the safety of the system, a full functional test of the system must be conducted
after commissioning, and a successful result obtained.
Commissioning the 3SK1safety relays
The 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 configuration of the device is then
displayed on the configuration LEDs for approx. 3 s.
If a valid configuration is set and the potentiometer setting has been left unchanged, the
device is now ready for operation and is in safety mode.
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 jumpered ( 24 V DC) if it is not to be used.
Monitoring of the feedback circuits is not optional.
