DS200DCFBG1A燃机电气模块
报警LED亮起，但继电器不工作。
检查通道是否处于禁用状态，如有必要，取消禁用。检查所安装的继电器接口卡类型是否能够支持预期警报。检查通道卡配置，以查看继电器是否针对预期操作进行了配置。用另一个相同类型的继电器接口卡切换继电器接口卡，并使用工程卡报警测试功能测试继电器动作。有关报警LED，请参阅前面的指南。有关报警LED，请参阅前面的指南。工程卡未安装工程密钥。如果已安装钥匙，但未锁定（）LED未点亮，请检查工程钥匙的状况，必要时更换。所选功能在现有通道硬件上不可用。选择一个频道卡。检查工程卡通电（）指示灯是否亮起。这些操作说明是指在未安装工程钥匙的情况下，可用于系统一般操作和查询的设施。可能影响系统运行方式的设施包含在工程师操作说明第7章中，该章指安装工程钥匙时可用的设施。要重置通道控制卡，短按并释放其前面板reset/SELECT（重置/选择）按钮。这将：a.重置与控制卡相关的所有锁定和非活动警报。b、 取消所有锁定和非活动警告消息。c、 重置峰值读数显示。d、 确认存在更新条件。
用户操作例程
根据操作的键盘功能按钮，可以执行以下用户操作例行程序：通道复位。频道选择。查看报警级别。催化传感器电流检查。传感器信号监测。接受更新警报。查看时钟/日历。启动维护记录打印输出。当使用工程卡按钮控件选择通道控制卡时，通道复位和选择由通道卡复位/选择按钮执行，同时执行其余功能。一次只能选择一个通道卡，当选择时，其微处理器监测工程卡按钮功能，以确定应采取的措施。按住所需通道卡reset/SELECT（重置/选择）按钮约五秒钟，可将最大/最小信号值、STEL和LTEL值以及时间计算重置为零。在此期间，所选图标将开始闪烁打开和关闭，当闪烁停止时，重置完成。要从工程卡选择操作控制的通道卡，请按住所需的通道卡RESET/select（重置/选择）按钮约1.5秒，直到图标显示从正常显示变为如下所示的所选显示。要取消选择所选通道卡，短按其前面板RESET/SLECT（重置/选择）按钮。通道卡将被取消选择，任何正在进行但尚未确认的用户操作都将被取消。应注意，除非再次瞬时按下复位/选择按钮，否则通道卡不会复位。
The ALARM LED is illuminated but there is no relay operation.
Check to see if the channel is in the inhibited condition and if necessary remove the inhibit. Check to see that the type of relay interface card fitted can support the expected alarm. Check the channel card configuration to see that the relay is configured for the expected operation. Swop the relay interface card with another of the same type and test relay action by using the Engineering Card alarm test function. See previous guide for ALARM LED. See previous guide for Alarm LED. Engineering Card has no Engineering Key fitted. If key is fitted but the unlocked ( ) LED is not illuminated check the condition of Engineering Key and replace if necessary. The function selected is not available on the channel hardware present. Select a channel card. Check that the Engineering Card power on ( ) LED is illuminated.These operating instructions refer to the facilities available for general operation and interrogation of the system without the Engineering Key fitted. Facilities that may effect the way the system operates are covered in the Engineer's Operating Instructions Chapter 7 which refers to facilities available when the Engineering Key is fitted.To reset a channel control card, briefly push and release its front panel RESET/SELECT push-button. This will: a. Reset all latched and non-active alarms associated with the control card. b. Cancel all latched and non-active warning messages. c. Reset the peak reading display. d. Acknowledge an update condition should one be present.
USER OPERATING ROUTINES
Depending upon which keypad function push-buttons are operated, the following user operating routines may be performed: Channel reset. Channel select. View alarm levels. Catalytic sensor current check. Sensor signal monitoring. Accept an update alarm. View clock/calendar. Initiate a maintenance record printout. Channel reset and select are performed by the channel card RESET/ SELECT push-button while the remaining functions are performed, when a channel control card is selected using the Engineering Card push-button controls. Only one channel card can be selected at any one time and while selected its microprocessor monitors the Engineering Card pushbutton functions to determine what action should take place.The max/min signal values, STEL and LTEL values, and time calculations may be reset to zero by pushing and holding down the required channel card RESET/SELECT push-button for approximately five seconds. During this period the selected icon will start to flash on and off, and when the flashing stops the reset is complete.To select a channel card for operations controlled from the Engineering Card, push and hold the required channel card RESET/SELECT pushbutton for approximately 1.5 seconds until the icon display changes from the normal display to the selected display as shown below To deselect a selected channel card, briefly push its front panel RESET/SELECT push-button. The channel card will be deselected and any user operations in progress which have not been confirmed will be cancelled. It should be noted that the channel card will not be reset unless the RESET/ SELECT push-button is again momentarily pushed.
