Page 5: Introduction
PNOZ e8.1p Introduction Validity of documentation This documentation is valid for the product PNOZ e8.1p. It is valid until new documentation is published. This operating manual explains the function and operation, describes the installation and provides guidelines on how to connect the product. -
Page 6: Safety
Safety Intended use The PNOZ e8.1p is the evaluation device for safe line inspection with PLID d1. As the eval- uation device for PLID d1, the PNOZ e8.1p achieves PL d (Cat. 2) in accordance with EN ISO 13849-1 and SIL CL 2 in accordance with EN IEC 62061. -

Page 15: Logic Connection Between Several Units
The unit with the lowest SIL/PL value determines the SIL/PL value of the entire circuit. PNOZ e1p, PNOZ e8.1p: These units do not have logic inputs. Their safety outputs can be used to logically link the units to the logic inputs of other PNOZelog units or to the cas- cading inputs from PNOZmulti units. -
