● Two isolated inputs are configured to dual‑channel inputs of the STO function:
STO1/STO2.
● To facilitate commissioning, additional pin with supply voltage (+24V) is
integrated. The bridging of the 24 V terminal to STO1/STO2 is needed in case the
safety circuit is installed but no STO function is needed.
Note
If you need STO, you must remove the short circuit jumper.
