Action
Make sure that the drive STO function is configured and validated. See
the hardware manual.
Checks and settings with no voltage connected
Stop the drive and do the steps in section Electrical safety precau-
tions (page 12) before you start the work.
Make sure that the necessary ATEX/UKEX markings are attached.
Make sure that the classification of the motor thermal protection function
corresponds to the Ex classification of the environment and the Ex motor.
The motor manufacturer selects the PTC sensors for the motor temper-
ature measurement according to the specified temperature class. Make
sure that the temperature on-off resistances match those of the module.
If you have done any changes to the wiring, do a check of the connec-
tions against the applicable circuit diagrams.
Make sure that the installation of the motor temperature sensor complies
with the requirements for the applicable type of protection.
Make sure that the SIL/PL of the safety function meets the target SIL/PL.
Make sure that the wires are connected to the correct terminals and
that the terminal connections are tightened to the correct torque.
Settings with voltage connected
Make sure that you have set all the necessary parameters for the safety
function.
Validation test procedure
Make sure that you can run and stop the motor freely during the test.
Start the drive and make sure that the motor is running.
Do an overtemperature monitoring test: increase the resistance in the
PTC input to more than 4 kohm (for example, open the circuit by discon-
necting the wires).
Make sure that the correct indications are activated: the SMT fault and
other indications depending on the parameter settings.
Make sure that the STO is activated and that the motor coasts to a stop.
