Wire symbols into circuits
Draw wires from symbol to symbol with the Wire tool, put each wire on a circuit with the chips, route it through waypoints, erase a wire, and change a circuit later.
A wire in ePlan joins two symbols and belongs to a circuit. The circuit gives the wire its colour and groups it for Test mode and the PDF's legend.
Draw a wire
- Tap Wire, beside the palette. A banner shows Draw and Erase, and the circuit chips appear.
- Tap a chip: one of the plan's circuits, New for the next number (C1, C2 and on), or None.
- Tap the symbol the wire starts on.
- To route the wire, tap empty spots on the plan. Each one becomes a point the wire passes through.
- Tap the symbol it ends on. The wire appears as a smooth curve in its circuit's colour.
- Draw the next wire, or tap Done to leave the tool. Cancel drops a wire you have started.
Which circuit a wire takes
- The chip you chose. With None, the circuit of the symbol it starts on, or else of the one it ends on.
- A symbol with no circuit of its own takes the circuit of the wire drawn to it.
- Circuits made with New stay in the chip row until you leave the tool.
- C1 is blue, C2 red, C3 amber and C4 green, and the colours run on to C10. A circuit you name yourself gets a colour too.
The rules wires follow
- A wire starts on a symbol and ends on another. It cannot end in empty space.
- Two symbols share at most one wire. Drawing a second between them does nothing.
- Wires end at the centre of their symbols and follow them when you move them.
- Deleting a symbol deletes its wires, and Undo brings both back.
Erase a wire
- In the Wire tool, choose Erase.
- Tap a wire. Wire removed appears with an Undo button, in case it was the wrong one.
Change a wire later
- Outside the Wire tool, tap a wire to select it.
- Tap the tag button to change its circuit, or the bin to delete it.
What to draw
- Draw each switch to the light it controls, and a two-way pair (a 3-way pair in the US) to each other and to the light. Simulate in Test mode tests exactly that.
- Bring every circuit back to the board, the panel in US symbols. Check counts a device as fed only when wires reach it from a board.
See Test a plan, and the two-way switch article for how a switched pair works.
