13.6 Activation of STO function
The STO function will be activated in the factory upon request. Activation/deactivation by the customer
is not permissible. Non-permissible manipulation by the customer will result in all warranty, guarantee
and liability rights becoming null and void.
13.7 Functional check
When it comes to checking the function of the safety-relevant signals and functions, ensure that there
is nobody in the lift car. Next, disable the external calls in the lift controller.
It is recommended that the following tests be carried out by disconnecting the STO signals at the
relevant relays and not the frequency inverter directly. If the STO signals are disconnected on the
frequency inverter side, ensure in any case that the cables are not in contact with any components of
the frequency inverter (danger of destruction!).
STO fault messages can only be deleted by disconnection of the mains voltage.
13.7.1 Checking the GS signal
To check the function of the GS signals, disconnect the cable at terminal "53" and make a call via the
lift controller. The frequency inverter must not supply power to the motor and the parking brake must
remain engaged (no movement of lift cage).
Now, connect the cable to terminal 53 again and repeat the test while the lift is running. An emergency
stop must be performed immediately (lift car must be stopped).
Then connect the cable to terminal 53 again.
13.7.2 Checking the STO signals
To check the function of the STO signals, disconnect the cable at terminal "STO1" and make a call via
the lift controller. The frequency inverter must not supply power to the motor and the parking brake
must remain engaged (no movement of lift cage). The fault message relay TÜ of the frequency
inverter drops out and the fault message "STO Error" appears on the frequency converter display.
Then connect the cable to terminal "STO1" again and repeat the procedure with signal "STO2".
Repeat both tests while the lift is running. In both cases, an emergency stop must be performed
immediately (lift car must be stopped). The fault message relay TÜ of the frequency inverter drops out
and the fault message "STO Error" appears on the frequency converter display.
13.7.3 Checking the contactor drop-out monitor
To check the function of the contactor drop-out monitor, disconnect the cable from the corresponding
input of the lift controller; then make a call via the lift controller. After the end of the travel operation,
this state must be recognized and displayed by the lift controller. A new call must not result in another
travel operation.
After completion of the tests, check the wiring once again and enable external calling again.
