PNOZ s1 Safety relay PNOZ s1 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 For your safety } Only install and commission the unit if you have read and understood these operating instructions and are familiar with the applicable regulations for health and safety at work and accident prevention.
PNOZ s1 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. } The unit has an electronic fuse.
PNOZ s1 Installation Install base unit without contact expansion module: } Ensure that the plug terminator is inserted at the side of the unit. Connect base unit and PNOZsigma contact expansion module: } Remove the plug terminator at the side of the base unit and at the contact expansion module. } Connect the base unit and the contact expansion module to the supplied connector before mounting the units to the DIN rail.

Operation The unit is ready for operation when the Power LED is permanently lit.
PNOZ s1 Status indicators Power, In1, In2 Input circuit is closed. Out Safety contacts are closed and semiconductor output Y32 carries a high signal. Reset 24 V DC is present at S34. Error indicators Fault Diagnostics: Plug terminator not connected } Remedy: Insert plug terminator, switch supply voltage off and then on again. Fault Diagnostics: Internal error, unit defective } Remedy: Switch supply voltage off and then on again, change unit if necessary.
