ROBUS PROTON UNIVERSAL 360° PIR
| Preliminary Information | |
|---|---|
| Release Year | 2016 |
| Leak Risk | Low |
| Batteries | None |
| Mounting Technology | Through Hole, SMD |
| Capacitor Types | Film (X2), Aluminum Electrolytic, Ceramic |
| Destructive Entry | No |
| Power Requirements | |
| Input Voltage | 220 - 240 VAC 50/60 Hz |
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.
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.
-
Damaged metalized film in JIMSON GMF X2 100 nF film capacitor
Solutions
- Replace both X2 film capacitors (C29 & C30)
Disassembly Notes
 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.
