# D11 類比輸出警報
### 定義
此功能用於設定類比輸出超出4-20mA 範圍時，流量計的警報模式，預設關閉。警報代碼屬於Alarm - B 。
### 注意事項
1. 4 mA 與 20 mA 的對應數值可分別於 **E07（4 mA）** 與 **E08（20 mA）** 參數中進行調整。
2. 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 %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.lorric.com/qr/fp-as510-paddle-wheel-flowmeter-manual-chinese-v2/parameters/d-jing-bao-ji-tong-zhi-she-ding/d11-lei-bi-shu-chu-jing-bao.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
