The ROBUS PROTON UNIVERSAL 360° PIR sensor (RU360-01) is a typical ceiling mountable PIR motion sensor intended for indoor lighting applications sold in the Australian and EU markets.

Alternate re-brands (OEM unknown)

  • MATelec FMS-12080

Known Issues

Device does not function or behaves erratically

Causes

  • Film capacitor in the 'capacitive dropper' power supply has degraded and no longer passes enough current for the device to operate correctly.

Solutions

  • Replace both X2 film capacitors (C29 & C30)

Disassembly Notes

warning WARNING This device contains a non-isolated mains voltage 'capacitive dropper' style power supply. Low voltage circuity still poses a shock hazard.
  • Front bezel quarter turn to remove and expose controls
  • 4 self tapping screws hold enclosure together, PH2 bit size
  • 3 plastic clips hold enclosure onto surface mounting plate
  • Ensure potentiometers are correctly aligned with plastic knobs during re-assembly

Replacement Parts

The replacement Vishay 339 series film capacitors have higher ratings and should be expected to last far longer than the original capacitors.

If parts are not available or different selection is preferred, you can use the values in the Original Parts section to perform a parametric search

note NOTE Vishay recommends the F1772 series X2 'high stability grade' film capacitor for 'capacitive dropper' power supply applications. Use this if available in correct package for your device, otherwise Vishay 339 series or similar will suffice.
