英国莫伯雷Mobrey超音波液位傳訊器中文操作說明書(续四)
Application/Duty: Flow Measurement 運用/ 程式:流量測量
1. With power on and the MSP900SH transmitter giving a 4-20mA signal to the MCU901 unit (see previous pages), you can
now programme the MS901 for an application. This application example is for a Wet Well with pump control.
與開啟電源和這MSP900SH感測器供給4-20mA信號到這MCU901裝置 (查看前頁)。現在可以應用MCU901程序表。這範例
是關於接液部與泵浦控制。
Requirement需求
.Live flow measurements in units of cubic metres per second. 測量流量運轉單位在米立方每秒(m3/s)。
.Totalised flow in cubic metres per second.
流量總計在米立方每秒(m3/s)。
Input Data輸入資料
.Channel Shape 渠道外形:Flume流水槽
.Maximum depth 深度*大值:1 metre1公尺(m)
.Maximum rate: 1 cubic metre per second
測量*大值:1(m3/s)

2. Navigate the menu system to get to the “Duty Wizard” screen. Key-press hints are alongside the screens
操作這選單系統到取得〝運作變化〞螢幕。提示按鍵在螢幕側邊。

3. Start the “Duty” Wizard by pressing the yellow (ENTER) key once.
初啟這〝運作〞功能由黃色(ENTER)鍵按一次。
4. Work through the “Duty” Wizard prompts (see next page) until completion; this occurs when the menu system re-appears.
Keypad hints, for the illustrated Wizard sequence on the next page, are provided alongside the prompts. If applicable, adapt the example to suit your application.
運作完成這〝運用〞功能提示訊息(查看下頁)直到完成時;出現這前選單系統版本-顯示。
按鍵提示,為用圖說明功能連續在下一頁,是以側邊提示為條件,假如可應用,你合適的例子應用。
5. Circled numbers in the illustrated Wizard sequence relate to these notes:循環數字在這說明正常連續敘述以下註解:
① Select “Flow” from the multiple-choice list. 從選擇〝流量〞多重-選擇一覽表。
② Enter the maximum rate of flow. 進入測量*大值流量。
③ Enter the present height of maximum flow in the Flume. 進入呈現在流水槽高度的*大值流量。
④ Option of registering flow as 0 m 3 /s on the MCU901 while the measured flow rate is below a programmed cut off.
選項流量設定在0m3/s開啟MCU901時間受限在下面流量測定程式切換。
⑤ Programme the 4-20mA output span with a flow rate range (e.g. 0 m 3 /s to 1 m 3 /s)
程式設計4-20mA輸出全長與流量範圍 (e.g. 0m3/s到1m3/s)。
⑥ Option to set-up a relay to output (100ms) pulses representing the totalised flow.
選擇向上設定繼電器到輸出(100ms)表示脈衝流量總計。
6. Return to the main menu by holding the ESC key for a few seconds, releasing it when the main menu appears. Next, go on-line by selecting the “Go on-line” menu option and then pressing the ENTER key once. Finally, press the ESC key repeatedly until the primary display appears. The flow measurement will be live on the primary display.
返回到主要選單按住ESC鍵為小數**,放開時那主要選單顯示,下一個,執行開啟-行經由選擇〝執行開啟-行〞選項可選擇所要按一次ENTER鍵。*後按ESC鍵重複按直到原始陳列顯示等。這流量測量將轉動到原始顯示。
Other Features其他特徵
Restoring factory defaults (Erases all user entered data) 還原原廠設定值 (刪除使用者全部輸入資料)
To re-set the MCU901 unit back to the factory defaults, navigate to the “Load Defaults” screen and press the ENTER key twice. 到指示設定MCU901單位還原原廠設定值,操作到載入預設值螢幕和按兩次ENTER鍵。
PIN Security**PIN(密碼)
Personal Identification Number (PIN) security prevents unauthorised people from programming the MCU901 control unit.
Typically, this is set-up when all the other programming has been completed. As with Bankcards, there is one PIN number.
確認個人密碼(PIN)**預防別人未經許可進入MCU901控制器編製程序。
典型的,這反黑是所有編製程序完整時。如同與銀行信用卡有一組PIN號碼。
The factory default is for PIN security to be inactive. To activate, navigate the menu system to the PIN screen and edit a 4-digit personal identification number (PIN) that you want. The PIN is edited with the arrow keys and confirmed with the ENTER key; the 4-digit PIN will then be replaced by “- - - -“ to indicate that PIN security is active. (By default, PIN is a0 if inactive).
這原廠預設值是為了防護PIN失效。到編組,操作選單系統到PIN螢幕和編輯個人4個數字(PIN) 號碼會要求你確認。這PIN是編輯應對那箭頭鍵和被證實對應ENTER鍵;這4個��字應對PIN值被那取代〝----〞到指示那PIN是**有效。(經由預設,即使PIN是0也不動作)。
Once PIN security is activated, a prompt for the PIN will appear when needed for an activity, such as starting a Wizard. If correctly entered, no further PIN requests are made unless the “Cancel Password” option is selected from the MAIN MENU screen. This menu option appears only after correctly entering the PIN; the option disappears when selected, therefore making the MCU901 secure and prompt for the PIN when needed.
一個PIN**編組是提示訊息為了PIN與當顯示要求時為任一操作,如此一啟動運作如果正確輸入,PIN沒有更進一步要**成功的除非這〝取消暗語〞從選項選擇這MAIN MENU(主要選單)螢幕。這選單只是依照選項顯示正確進入這PIN;當選項取消選擇時,因此構成MCU901**和為了提示訊息當PIN要求時。
