KONGSBERG RDIOR420船舶工控卡件
量程信號(hào)校準(zhǔn)注：如果首次校準(zhǔn)新傳感器，請(qǐng)使用第10節(jié)中的第一量程程序。要選擇量程操作，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(guò)顯示選擇圖標(biāo)檢查所選控制卡是否指示其已被選中。（3） 按下工程卡量程按鈕，所選控制卡將自動(dòng)禁用，控制卡信息顯示屏上將顯示以下顯示之一：a.表示氣體讀數(shù)穩(wěn)定。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。當(dāng)控制卡執(zhí)行以下操作時(shí)，所選控制卡將在信息顯示屏上顯示oooo：a.將自身歸零到當(dāng)前傳感器信號(hào)，前提是這在配置的零信號(hào)上限和下限值范圍內(nèi)。然后，控制卡將自動(dòng)返回到正常選定狀態(tài)。b、 如果信號(hào)超出存儲(chǔ)的信號(hào)限制，則所選控制卡顯示屏上將顯示錯(cuò)誤消息。c、 自動(dòng)返回到正常選定狀態(tài)，但控制卡上的禁用將保持激活狀態(tài)。（8） 如果量距信號(hào)校準(zhǔn)（第9節(jié)）不遵循此程序，則移除抑制。在裝有2.4版軟件的控制卡上，當(dāng)零抑制啟用時(shí)，在應(yīng)用量距氣之前，量距氣濃度可能顯示為零（0）。在顯示讀數(shù)之前，不得進(jìn)行調(diào)整。
檢查所選控制卡
數(shù)字顯示器指示需要使用的量距氣濃度，如果沒(méi)有，則使用和按鈕升高或降低指示，直到顯示正確的濃度。注：1.模擬顯示器將繼續(xù)顯示當(dāng)前傳感器實(shí)時(shí)信號(hào)電平。2.在此階段按下按鈕將使控制卡返回所選模式，而不會(huì)更改原始量距設(shè)置。根據(jù)所選通道傳感器說(shuō)明手冊(cè)，以流速應(yīng)用量距氣一段時(shí)間。注：1.除氧氣外，每個(gè)傳感器在標(biāo)定量程前都應(yīng)調(diào)零。參見(jiàn)第8.2節(jié)。雖然可以使用低至傳感器fsd值15%的量距氣，但建議使用40%或以上的值。（6） 當(dāng)信息顯示表明讀數(shù)穩(wěn)定時(shí)，按下按鈕。然后，選定的控制卡將顯示在數(shù)字顯示器上，同時(shí)執(zhí)行以下操作：a.將其量程校準(zhǔn)參數(shù)調(diào)整為新的顯示值，前提是該值在配置的量程上限和下限信號(hào)限值范圍內(nèi)。b、 將上次校準(zhǔn)日期設(shè)置為當(dāng)前日期，如果啟用，則重置校準(zhǔn)提醒。c、 自動(dòng)返回到正常選定狀態(tài)，但控制卡上的禁用將保持激活狀態(tài)。d、 如果顯示的值超出存儲(chǔ)的信號(hào)限制，則顯示錯(cuò)誤消息。e、 在為催化傳感器輸入配置的控制卡上，當(dāng)前傳感器信號(hào)將與新傳感器時(shí)記錄的信號(hào)進(jìn)行比較。如果傳感器的靈敏度降至原始值的50%以下，將顯示警告。重要事項(xiàng)：當(dāng)量距氣已清除且傳感器信號(hào)已恢復(fù)正常時(shí)，不要忘記將控制卡恢復(fù)到未禁用狀態(tài)。
SPAN SIGNAL CALIBRATION
Note: If a new sensor is being calibrated for the first time, use the 1st Span procedure in Section 10. To select the span 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 SPAN push-button and the selected control card will automatically be inhibited and one of the following displays will be shown on the control card 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. The selected control card will display oooo on the message display while the Control Card carries out the following: a. Zeroes itself at the current sensor signal, providing this is within the configured upper and lower zero signal limit values. The control card will then automatically return to the normal selected state. b. If the signal is outside the stored signal limits an error message will be displayed on the selected control card display. c. Automatically return to the normal selected state, however, the inhibit on the control card will remain active. (8) If the Span Signal Calibration (Section 9) is not to follow this procedure, remove the inhibit.On Control Cards fitted with version 2.4 software, when zero suppression is enabled the span gas concentration may be displayed as zero (0) until the span gas is applied. No adjustment sould be made until a reading is shown.
Check that the selected control card
digital display indicates the required span gas concentration to be used, if not, use the and push-buttons to raise or lower the indication until the correct concentration is displayed. Note: 1. The analogue display will continue to show the current sensor live signal level. 2. Pushing the button at this stage will return the control card to the selected mode without any changes to the original span setting Apply the span gas at a flow rate and for a time according to the selected channels sensor instruction manual. Notes: 1. Apart from oxygen, every sensor should be zeroed before being spanned. See Section 8. 2. Although a Span Gas as low as 15% of the fsd value of the sensor may be used, it is recommended that a value of 40% or above is used. (6) When the message display shows to indicate a stable reading, push the push -button. The selected control card will then display on the digital display while it carries out the following: a. Adjusts its span calibration parameter to the new displayed value, providing this is within the configured upper and lower span signal limit values. b. Set the last calibration date to the current date and reset the calibration reminder if this is enabled. c. Automatically return to the normal selected state, however, the inhibit on the control card will remain active. d. If the displayed value is outside the stored signal limits, display an error message. e. On control cards configured for catalytic sensor inputs, the present sensor signal will be compared with that recorded when the sensor was new. A warning will be displayed if the sensitivity of the sensor has fallen to below 50% of its original value. IMPORTANT When the span gas has been removed and the sensor signal has returned to normal, do not forget to return the control card to its uninhibited state.
