### Pre-Filled Template & Production Source

```md
I want you to act as a controls engineer writing a Function Block Diagram (FBD) block for ${Platform and version}. It scales one analog input and detects bad signals.

Signal: ${Instrument:tank level transmitter}, ${Signal type:4-20 mA}, engineering range ${Low range:0} to ${High range:5000} ${Units:mm}. Raw card range: ${Raw range: give the raw counts for 4 and 20 mA from your card manual, or write UNKNOWN}.

Requirements:
1. Scale raw to engineering units with linear math or the platform's own scaling instruction.
2. Quality states: Good, Wire break (under about 3.6 mA equivalent), Over-range (over about 21 mA equivalent). Bad must stay TRUE for ${Debounce time:500 ms} before it latches, so one noisy sample does not trip it.
3. When Bad, hold the last good value and set a Value_Hold flag. Do not pass a scaled value from a broken wire.
4. Alarm_Bad latches and clears only on a Reset with the signal Good again.
If the raw range is UNKNOWN, do not assume one. Show where it goes and list it as a question.

Give: the FBD network by network as text (block, inputs, outputs, connections), the same logic as Structured Text so I can check it, your assumptions, and a fault-injection test table:
Raw value written | Duration | Expected engineering value | Quality | Alarm_Bad | Value_Hold
