KONGSBERG RDIOR420船舶工控卡件
量程信号校准注：如果首次校准新传感器，请使用第10节中的第一量程程序。要选择量程操作，请按以下步骤进行：（1）将工程钥匙插入工程卡前面板插座，并检查解锁LED（）是否亮起。（2） 按住所需的控制卡RESET/SELECT（重置/选择）按钮约1.5秒，并通过显示选择图标检查所选控制卡是否指示其已被选中。（3） 按下工程卡量程按钮，所选控制卡将自动禁用，控制卡信息显示屏上将显示以下显示之一：a.表示气体读数稳定。b、 A A A表示气体读数上升。c、 V V V V表示气体读数下降。当控制卡执行以下操作时，所选控制卡将在信息显示屏上显示oooo：a.将自身归零到当前传感器信号，前提是这在配置的零信号上限和下限值范围内。然后，控制卡将自动返回到正常选定状态。b、 如果信号超出存储的信号限制，则所选控制卡显示屏上将显示错误消息。c、 自动返回到正常选定状态，但控制卡上的禁用将保持激活状态。（8） 如果量距信号校准（第9节）不遵循此程序，则移除抑制。在装有2.4版软件的控制卡上，当零抑制启用时，在应用量距气之前，量距气浓度可能显示为零（0）。在显示读数之前，不得进行调整。
检查所选控制卡
数字显示器指示需要使用的量距气浓度，如果没有，则使用和按钮升高或降低指示，直到显示正确的浓度。注：1.模拟显示器将继续显示当前传感器实时信号电平。2.在此阶段按下按钮将使控制卡返回所选模式，而不会更改原始量距设置。根据所选通道传感器说明手册，以流速应用量距气一段时间。注：1.除氧气外，每个传感器在标定量程前都应调零。参见第8.2节。虽然可以使用低至传感器fsd值15%的量距气，但建议使用40%或以上的值。（6） 当信息显示表明读数稳定时，按下按钮。然后，选定的控制卡将显示在数字显示器上，同时执行以下操作：a.将其量程校准参数调整为新的显示值，前提是该值在配置的量程上限和下限信号限值范围内。b、 将上次校准日期设置为当前日期，如果启用，则重置校准提醒。c、 自动返回到正常选定状态，但控制卡上的禁用将保持激活状态。d、 如果显示的值超出存储的信号限制，则显示错误消息。e、 在为催化传感器输入配置的控制卡上，当前传感器信号将与新传感器时记录的信号进行比较。如果传感器的灵敏度降至原始值的50%以下，将显示警告。重要事项：当量距气已清除且传感器信号已恢复正常时，不要忘记将控制卡恢复到未禁用状态。
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.
