產品詳情內容介紹
B&R 5AP923.1906-F01終端顯示屏
校準按照中的規定，讓連接的傳感器穩定一段時間傳感器手冊。按中所述調整催化傳感器的傳感器頭電流第7章第7節至傳感器所示的要求值操作說明。
使用針對所用傳感器類型指定的程序，遵循第7章第8節中的零量程和第一量程操作指南和10，并校準每個通道。維護為確保系統正常運行，維護應根據現場規定定期進行所用傳感器類型的說明。對于安裝在應遵循歐盟標準EN 50073?！?br/>
系統應保持清潔并保持暢通灰塵和油脂。
應每年進行以下檢查，或根據當地法規或程序的要求更頻繁地：
（1） 檢查并在必要時擰緊直流輸入端的所有終端卡、四中繼接口卡和（如果安裝到擴展）中繼卡。
（2） 檢查工程卡通電（）綠色LED是否為點亮，所有其他LED熄滅。
（3） 檢查正在使用的每個通道、每個控制卡的顯示，表示正常讀數，沒有錯誤消息。
（4） 依次選擇每個控制卡的每個通道，并檢查通道傳感器信號讀取，如果催化傳感器連接時，傳感器電橋電流。
（5） 將工程鑰匙安裝在工程卡上，選擇每個每個控制卡的通道依次進入報警測試功能。
（6） 檢查警報級別、警報LED操作、警報繼電器操作以及每個通道的顯示操作。
（7） 檢查所有故障和抑制繼電器的工作情況。
（8） 檢查傳感器處于無氣體環境中時，顯示屏表示零。如果合適，使用ZERO功能。
注：對于氧氣應用，只能操作零點功能在無氧環境中。
正常大氣條件下顯示器應指示21%±0.5%v/v的條件，這可以是使用SPAN功能進行調整。
系統57控制卡和工程卡持續執行硬件、軟件和傳感器完整性的自檢活動出現問題時，取決于問題，控制卡將在LCD顯示屏或將操作故障LED和繼電器輸出。LCD信息顯示系統內的操作錯誤顯示為錯誤代碼。使用的錯誤代碼及其含義如下在以下各節中列出。這些部分還包含適當的與錯誤消息的可能原因有關的信息并指示錯誤如何影響通道卡。
MAINTENANCE
To ensure that the system functions correctly, maintenance should be carried out on a regular basis as dictated by the site regulations and instructions for the type of sensor being used. For installations in the EU, EN 50073 should be followed.” The system should be maintained in a clean condition and kept free from dust and grease. The following checks should be made annually, or more frequently if required by local regulations or procedures: (1) Check and if necessary tighten all terminations to the DC Input Card, Quad Relay Interface Cards and if fitted to the Expansion Relay Card. (2) Check that the Engineering Card power on ( ) green LED is illuminated and all other LEDs are extinguished. (3) Check the display of each channel in use, of every control card, indicates a normal reading with no error messages. (4) Select each channel of every control card, in turn, and check that channels sensor signal reading and, if a catalytic sensor is connected, the sensor bridge current. (5) With the Engineering Key fitted to the Engineering Card, select each channel of every control card in turn and enter the alarms test function. (6) Check the alarm levels, alarm LED operation alarm relay operation and display operation for each channel. (7) Check the operation of all fault and inhibit relays. (8) Check that, with the sensor in a gas free atmosphere, the display indicates zero. If appropriate adjust the zero reading using the ZERO function. Note: For oxygen applications the zero function should only be operated in an oxygen free atmosphere. Under normal atmosphere conditions the display should indicate 21% ± 0.5% v/v, this can be adjusted by using the SPAN function. The System 57 control cards and engineering cards carry out continual self checking of the integrity of the hardware, software and sensor operation. In the event of a problem, and depending on the type of problem, the control card will indicate either an error message on the LCD display or will operate the fault LED and relay output.
CALIBRATION
Leave the connected sensors to stabilise for a period as specified in the sensor manual. Adjust the sensor head current of catalytic sensors as described in Chapter 7 Section 7 to the required value as indicated in the sensor operating instructions. Using the procedures specified for the type of sensors being used, follow the zero and 1st span operational guide in Chapter 7 Sections 8 and 10, and calibrate each channel.
Operating errors within the system are indicated on the LCD message display as an error code. The error codes used and their meaning are listed in the following sections. These sections also contain appropriate information pertaining to the likely cause of the error message being displayed and an indication on how the error affects the operation of the channel card.
