Page 3: For Your Safety
PNOZ s3 PNOZ s3 safety relay The safety relay provides a safety-related interruption of a safety circuit. The safety relay meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1 and may be used in applications with E-STOP pushbuttons Safety gates Light beam devices For your safety... -
Page 4: Safety Features
PNOZ s3 Safety features The relay meets the following safety requirements: The circuit is redundant with built-in self-monitoring. The safety function remains effective in the case of a component failure. The correct opening and closing of the safety function relays is tested automatically in each on-off cycle. -

PNOZ s3 Manual start: Unit is active once the input circuit is closed and then the start circuit is closed. Monitored start with falling edge: Unit is active once – the input circuit is closed and then the start circuit is closed and opened again. –... -
Page 6: Preparing For Operation
PNOZ s3 Calculation of the max. cable length l in the input circuit: lmax / km = max. overall cable resistance (see technical details) lmax / km = cable resistance/km Use copper wire that can withstand 60/75 °C. Sufficient fuse protection must be provided on all output contacts with capacitive and in- ductive loads. - Page 7 PNOZ s3 Connection Supply voltage Supply voltage Input circuit Input circuit Single-channel Dual-channel Emergency stop without detection of shorts across contacts Emergency stop with detection of shorts across contacts Safety gate without detection of shorts across contacts Safety gate with detection of shorts across contacts Light beam device or safety 24 V DC...

PNOZ s3 Fault Diagnostics: Power-up blocked due to short-term interruption at S12; input cir- cuits not operated simultaneously Remedy: Open both input circuits, S12 and S22, simultaneously and then close again. Fault Diagnostics: Power-up blocked due to short-term interruption at S22; input cir- cuits not operated simultaneously Remedy: Open both input circuits, S12 and S22, simultaneously and then close again. -
Page 11: Service Life Graph
PNOZ s3 Service life graph The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negli- gible. Example Inductive load: 0,2 A Utilisation category: AC15 Contact service life: 2,000,000 cycles Provided the application requires fewer than 2,000,000 cycles, the PFH value (see techni-... -
