PNOZ s5 PNOZ s5 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 } 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 s5 } Plug-in connection terminals (either spring-loaded terminal or screw terminal) 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 s5 } Dual-channel operation with detection of shorts across contacts: redundant input circuit, detects – earth faults in the start and input circuit, – short circuits in the input circuit and, with a monitored start, in the start circuit too, – shorts between contacts in the input circuit. Automatic start: Unit is active once the input circuit has been closed. } } Manual start: Unit is active once the input circuit is closed and then the start circuit is closed.
PNOZ s5 Wiring Please note: } Information given in the "Technical details" must be followed. } Outputs 13-14, 23-24 are instantaneous safety contacts, outputs 37-38, 47-48 are delay-on de-energisation safety contacts. } Semiconductor output Y32 should not be used for safety circuits! } To prevent contact welding, a fuse should be connected before the output contacts (see technical details). } Calculation of the max. cable length lmax in the input circuit: Rlmax = max.
PNOZ s5 Set operating modes } Switch off supply voltage. } Select operating mode via the operating mode selector switch "mode". } If the operating mode selector switch "mode" is in its start position (vertical position), an error message will appear.

LEDs indicate the status and errors during operation: LED on LED flashes Information Status indicators and error indicators may occur independently.
PNOZ s5 Reset 24 V DC is present at S34. Out Set delay time is running. Error indicators All LEDs off Diagnostics: Short across contacts/earth fault; unit switched off } Remedy: Rectify short across contacts/earth fault, switch off supply voltage for 1 min. Fault Diagnostics: Plug terminator not connected } Remedy: Insert plug terminator, switch supply voltage off and then on again.
PNOZ s5 In2 Fault Diagnostics: Power-up blocked due to short-term interruption at S22; input circuits not operated simultaneously } Remedy: Open both input circuits, S12 and S22, simultaneously and then close again. 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.
PNOZ s5 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 negligible. Example } Inductive load: 0,2 A } Utilisation category: AC15 } Contact service life: 1,000,000 cycles Provided the application requires fewer than 1,000,000 cycles, the PFH value (see technical details) can be used in the calculation.
