KONGSBERG RDIOR400船舶控制器
催化傳感器電橋電流調(diào)節(jié)與BEAD mA按鈕相關(guān)的操作僅適用于為催化輸入配置的控制卡。在選擇其他類型的控制卡的情況下按下按鈕無效，并顯示警告。要進(jìn)入催化傳感器電橋電流操作，請(qǐng)執(zhí)行以下操作：（1）將工程鑰匙插入工程卡前面板插座，并檢查解鎖LED（）是否亮起。（2） 按住所需的控制卡RESET/SELECT（重置/選擇）按鈕約1.5秒，并通過顯示選擇圖標(biāo)檢查所選控制卡是否指示其已被選中。（3） 按下工程卡BEAD mA按鈕，檢查所選控制卡信息顯示屏是否顯示mA，數(shù)字顯示屏是否顯示實(shí)際電橋電流。（4） 如果顯示的電橋電流未設(shè)置為所需值，則使用和按鈕升高或降低指示的電橋電壓讀數(shù)，直到顯示所需值。注：1.只能設(shè)置在配置上限和下限值內(nèi)的電橋電流值。2.按下按鈕將取消顯示的電流，而不會(huì)更改存儲(chǔ)值。（5） 按下按鈕以永久設(shè)置新電橋電流。然后，選定的控制卡將自動(dòng)返回到正常選定狀態(tài)。在測試模式下，按下所選控制卡前面板的RESET/SELECT（重置/選擇）按鈕，可取消選擇所選的控制卡。模擬氣體液位和繼電器狀態(tài)將保持設(shè)置，允許同時(shí)測試多個(gè)控制卡。當(dāng)重新選擇控制卡時(shí)，該卡將返回測試模式。2.如果禁用被解除，外部繼電器將運(yùn)行
零信號(hào)校準(zhǔn)
要選擇零點(diǎn)操作，請(qǐng)按以下步驟進(jìn)行：（1）將工程鑰匙插入工程卡前面板插座，并檢查解鎖LED（）是否亮起。（2） 按住所需的控制卡RESET/SELECT（重置/選擇）按鈕約1.5秒，并通過顯示選擇圖標(biāo)檢查所選控制卡是否指示其已被選中。（3） 按下工程卡零按鈕，工程卡將自動(dòng)抑制選定的控制卡，以防止產(chǎn)生錯(cuò)誤報(bào)警。所選控制信息顯示屏上將顯示以下顯示之一：a.表示穩(wěn)定的氣體讀數(shù)。b、 A A A表示氣體讀數(shù)上升。c、 V V V V表示氣體讀數(shù)下降。（4） 檢查所選控制卡數(shù)字顯示器和條形圖是否繼續(xù)顯示當(dāng)前傳感器信號(hào)電平。注：在此階段按下按鈕將使控制卡返回所選模式，而不會(huì)改變原始零讀數(shù)。（5） 確保所選通道傳感器處于無氣體環(huán)境中。如果需要，根據(jù)所選通道傳感器說明手冊，在流速和時(shí)間下，應(yīng)用零氣體，通常不含待測氣體的空氣。（6） 當(dāng)信息顯示屏顯示時(shí)，要指示穩(wěn)定讀數(shù)，請(qǐng)按下按鈕。
CATALYTIC SENSOR BRIDGE CURRENT ADJUSTMENT
The operation associated with the BEAD mA push-button only applies when a control card has been selected that is configured for a catalytic input. The pressing of the push-button with other types of control cards selected has no effect and a warning is displayed to this effect. To enter the catalytic sensor bridge current operation, proceed as follows: (1) Plug the Engineering Key into the Engineering Card front panel socket and check that the Unlocked LED ( ) is illuminated. (2) Push and hold the required control card RESET/SELECT pushbutton for approximately 1.5 seconds and check that the selected control card indicates it has been selected by displaying the select icon. (3) Push the Engineering Card BEAD mA push-button and check that the selected control card message display shows mA and the digital display shows the actual bridge current. (4) If the displayed bridge current is not set to the required value, use the and push-buttons to raise or lower the indicated bridge current reading until the required value is displayed. Note: 1. Only bridge current values that are within the configured upper and lower limit values can be set. 2. Pressing the push-button will cancel the displayed current without alteration to the stored value. (5) Push the push-button to permanently set the new bridge current. The selected control card will then automatically return to the normal selected state.
A selected control card may be deselected while in the TEST mode by pushing the selected control card front panel RESET/ SELECT push-button. The simulated gas level and relay states will remain set allowing several control cards to be tested simultaneously. When the control card is reselected the card will return to the TEST mode. 2. If the inhibit is removed, the external relays will operate
ZERO SIGNAL CALIBRATION
To select the zero operation, proceed as follows: (1) Plug the Engineering Key into the Engineering Card front panel socket and check that the Unlocked LED ( ) is illuminated. (2) Push and hold the required control card RESET/SELECT pushbutton for approximately 1.5 seconds and check that the selected control card indicates it has been selected by displaying the select icon. (3) Push the Engineering Card ZERO push-button and the Engineering Card will automatically inhibit the selected control card to prevent false alarms being generated. One of the following displays will be shown on the selected control message display: a. Indicates a stable gas reading. b. A A A A Indicates a rising gas reading. c. V V V V Indicates a falling gas reading. (4) Check that the selected control card digital display and bar graph continue to display the current sensor signal level. Note: Pushing the push-button at this stage will return the control card to the selected mode without any changes to the original zero reading. (5) Ensure the selected channel sensor is in a gas free atmosphere. If required apply zero gas, normally air not containing the gas to be measured, at the flow rate and for a time according to the selected channels sensor instruction manual. (6) When the message display shows , to indicate a stable reading, push the push-button.
