KONGSBERG RDIOR400船舶控制器
催化传感器电桥电流调节与BEAD mA按钮相关的操作仅适用于为催化输入配置的控制卡。在选择其他类型的控制卡的情况下按下按钮无效，并显示警告。要进入催化传感器电桥电流操作，请执行以下操作：（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BEAD mA按钮，检查所选控制卡信息显示屏是否显示mA，数字显示屏是否显示实际电桥电流。（4） 如果显示的电桥电流未设置为所需值，则使用和按钮升高或降低指示的电桥电压读数，直到显示所需值。注：1.只能设置在配置上限和下限值内的电桥电流值。2.按下按钮将取消显示的电流，而不会更改存储值。（5） 按下按钮以永久设置新电桥电流。然后，选定的控制卡将自动返回到正常选定状态。在测试模式下，按下所选控制卡前面板的RESET/SELECT（重置/选择）按钮，可取消选择所选的控制卡。模拟气体液位和继电器状态将保持设置，允许同时测试多个控制卡。当重新选择控制卡时，该卡将返回测试模式。2.如果禁用被解除，外部继电器将运行
零信号校准
要选择零点操作，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） 按下工程卡零按钮，工程卡将自动抑制选定的控制卡，以防止产生错误报警。所选控制信息显示屏上将显示以下显示之一：a.表示稳定的气体读数。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。（4） 检查所选控制卡数字显示器和条形图是否继续显示当前传感器信号电平。注：在此阶段按下按钮将使控制卡返回所选模式，而不会改变原始零读数。（5） 确保所选通道传感器处于无气体环境中。如果需要，根据所选通道传感器说明手册，在流速和时间下，应用零气体，通常不含待测气体的空气。（6） 当信息显示屏显示时，要指示稳定读数，请按下按钮。
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.
