PNOZ s2 PNOZ s2 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 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 s2 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 s2 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.
PNOZ s2 Preparing for operation Operating modes The operating mode is set via the rotary switch on the unit. You can do this by opening the cover on the front of the unit. CAUTION! Do not adjust the rotary switch during operation, otherwise an error message will appear, the safety contacts will open and the unit will not be ready for operation until the supply voltage has been switched off and then on again. Set operating modes } Switch off supply voltage.

PNOZ s2 Operation The unit is ready for operation when the Power LED is permanently lit. LEDs indicate the status and errors during operation: LED on LED flashes Information Status indicators and error indicators may occur independently. In the case of an error display, the "Fault" LED will light or flash (exception: "Supply voltage too low"). An LED that is also flashing indicates the potential cause of the error. An LED that is lit and is static indicates a normal operating status.
PNOZ s2 Reset Fault Diagnostics: Position of rotary switch is not permitted or rotary switch was adjusted during operation. } Remedy: Switch supply voltage off and then on again. Power, In1, In2, Out, Reset, Fault Diagnostics: The operating mode selector switch "mode" is in its start position (vertical position) } Remedy: Switch off the supply voltage and set the required operating mode on operating mode selector switch "mode".
PNOZ s2 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 technical details) can be used in the calculation. To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With contactors, use freewheel diodes for spark suppression.
