What this worksheet captures
This worksheet is built to capture the field details that usually decide whether control voltage capture can move into a quote, replacement, or engineering review.
It is meant to keep the intake practical, consistent, and easier to hand off between maintenance, engineering, and purchasing.
- control voltage source
- measured voltage
- device or coil being fed
- voltage under load
- available schematic reference
When to use it
Use it when the field information is incomplete, when multiple people are touching the job, or when the replacement path depends on details that are easy to miss over email or phone.
Worksheet
Fill this in on-screen or print the page and carry it into the field so the same core details make it back to engineering, sourcing, or quote review.
| Field | Value | Notes |
|---|---|---|
Control voltage source Measure or read the actual control voltage from the schematic, terminals, or powered circuit instead of assuming the nominal value. |
||
Measured voltage Measure or read the actual control voltage from the schematic, terminals, or powered circuit instead of assuming the nominal value. |

Device or coil being fed Capture the exact field detail from the installed equipment, drawings, labels, or documentation that best answers this part of the job. |

Voltage under load Measure or read the actual control voltage from the schematic, terminals, or powered circuit instead of assuming the nominal value. |

Available schematic reference Use the installed wiring, one-line, or panel drawings so the replacement path can be checked against the real circuit. |
How to use it on site
Work from the installed equipment first, then collect the ratings, environment, fit notes, and related components that change the actual buying decision.
| Item | What it means in practice | Why buyers care |
|---|---|---|
| Core role | Define a published performance, application, or evaluation boundary | This is why ratings and standards matter during selection. |
| What engineers compare first | scope, device context, and what the label changes in the design | The first question is what the rating actually applies to. |
| Typical downstream decisions | enclosure choice, protection strategy, substitution risk, and compliance review | This is where the rating affects real projects. |
| Common confusion | Treating the summary label like a complete engineering or code answer | The summary is the starting point, not the final signoff. |
What to verify before sending it on
A worksheet is most useful when the captured values are checked for completeness before they move into sourcing or quote prep.
Important verification notes
Use the worksheet to structure the job, then confirm the final release path against the exact product-family data and installed conditions.
