What it represents
A transformer-fed indicator lamp includes a documented internal voltage-conversion arrangement. Its supply terminals and lamp indication are shown according to the selected assembly.
How to read it
- Use the assembly input rating rather than the internal lamp voltage as the wiring supply requirement.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State input voltage
- Name indicated condition
- Reference assembly terminals
A distinction that matters
A built-in lamp transformer is different from a separately drawn panel control transformer.
