# D14 類比錯誤警報

### 定義

此功能用於設定當儀表的 4-20mA 電流輸出 Iout 訊號發生異常時，流量計的警報模式，預設勿擾。警報代碼屬於Alarm - C 。

### 注意事項

勿擾模式表示發生異常時，螢幕顯示的顏色不會改變，但仍可在通訊部分顯示數字及狀態頁的位元顯示異常。

{% hint style="info" %}

#### **DND（Do Not Disturb，勿擾模式）說明**

當啟用 DND 模式 時：

* 主機雖能偵測異常，但不會亮起紅色背光警示
* 例如：若在 dnd 模式下出現 Alarm-A 「4 Off Pipe」 異常，背光不會亮起
* 不過異常內容仍會在「異常頁面」顯示
* 若主機有連接 RS485，監控系統仍可接收到異常訊號
* 若有設定 OCT 警報輸出，OCT 也會持續輸出警示訊號
  {% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.lorric.com/qr/fpas310-zhong-wen-v5/parameters/d-jing-bao-ji-tong-zhi-she-ding/d14-lei-bi-cuo-wu-jing-bao.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
