PNOZ s6.1 Safety relay PNOZ s6.1 The safety relay can be used as a two-hand control relay or for simultaneity monitoring. 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 The two-hand control relay meets the requirements of EN 574 Type IIIA. It forces the operator to keep his hands outside the danger zone area during the hazardous movement. It is designed for use in two-hand circuits.

PNOZ s6.1 Function description } The safety relay must be activated by simultaneously pressing two control elements (pushbuttons) within 0,5 s . If one or both pushbuttons are released or the contacts open, the unit interrupts the control command for the hazardous movement. } Reactivation: The output relays will not re-energise until both control elements have been released and re-operated simultaneously or the contacts have opened and then closed.
PNOZ s6.1 Preparing for operation } Supply voltage Supply voltage AC } DC Input circuit Input circuit Single-channel Dual-channel Two-hand pushbuttons with detection of shorts across contacts Simultaneity monitoring in safety gate applications with automatic start after the safety gate is closed ATTENTION! *The unit starts automatically when the E-STOP / safety gate device is released.
PNOZ s6.1 } Semiconductor output Legend } S1/S2: Two-hand pushbuttons 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.
PNOZ s6.1 Fault 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. Fault Diagnostics: Internal error, unit defective } Remedy: Switch supply voltage off and then on again, change unit if necessary.
PNOZ s6.1 Faults - malfunctions } Contact malfunctions: If the contacts have welded, reactivation will not be possible after the input circuit has opened. 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.
PNOZ s6.1 UB 48-240 VAC/DC 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. 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.
