13.3.6 Safety-related characteristic data for operation with a safe rotary
encoder
Safe encoders are certified in accordance with EN 61508, EN 13849 and EN 62061. In or-
der to achieve the safety level stated by the encoder, the safe evaluation device (PNOZ
s30) must normally detect designated errors. Details of the safe encoder's requirements of
the evaluation device can be found in the user documentation for the safe encoder. The en-
coder and evaluation device must be compatible.
