DS200DCFBG1A模塊GE燃機(jī)技術(shù)
EEPROM保存應(yīng)用程序配置數(shù)據(jù)。
如果存在校驗(yàn)和差異，或者在啟動(dòng)或定期自檢期間無(wú)法執(zhí)行校驗(yàn)和測(cè)試，則會(huì)顯示EEPROM故障消息。這是一個(gè)嚴(yán)重的卡故障，因此需要更換卡。Vps是用于設(shè)置讀數(shù)比例因子絕對(duì)值參考的電壓。無(wú)Vps消息顯示在未經(jīng)出廠測(cè)試的通道卡上。這是一個(gè)嚴(yán)重的卡故障，因此需要更換卡。Vps插件用于設(shè)置Vps參考，不適合操作傳感器。Vps plug-in fitted（Vps插件已安裝）消息是一條出廠測(cè)試消息，顯示時(shí)表示傳感器驅(qū)動(dòng)模塊連接已安裝特殊模塊。除非卡未正確配備VP1模塊。這是一個(gè)嚴(yán)重的卡故障，因此需要更換卡。如果通道卡在啟動(dòng)程序中未能設(shè)置正確的催化傳感器電橋電流，則會(huì)顯示當(dāng)前設(shè)置故障消息。檢查傳感器連接和電纜線路長(zhǎng)度，以確保未超過(guò)最大線路阻抗。如果通道卡沒(méi)有配置信息或配置無(wú)效，則會(huì)在啟動(dòng)期間顯示配置故障消息。這是一個(gè)嚴(yán)重的卡故障，因此需要更換卡。如果安裝在通道卡上的實(shí)際傳感器驅(qū)動(dòng)模塊與通道卡配置中選擇的類型不同，則在啟動(dòng)過(guò)程中會(huì)顯示錯(cuò)誤的插件消息。應(yīng)檢查插件與傳感器的兼容性，并相應(yīng)更改插件模塊或通道卡配置
錯(cuò)誤代碼含義
高完整性繼電器故障。高完整性繼電器輸出的實(shí)際狀態(tài)和要求狀態(tài)不匹配。檢查高完整性繼電器卡是否正確連接。如果可能，請(qǐng)使用另一個(gè)工作正常的高完整性繼電器或控制卡來(lái)確定要更換的卡。如果通道卡檢測(cè)到其操作中的故障或傳感器輸入的故障，則會(huì)顯示硬件故障消息。檢查傳感器連接。卸下通道卡，將其插入兼容的工作通道，并檢查其運(yùn)行情況（在此操作過(guò)程中可能會(huì)出現(xiàn)ER86，這是正常現(xiàn)象）。如果卡仍然指示有故障，則必須更換。如果卡正在工作，則應(yīng)更換傳感器。欠量程故障當(dāng)傳感器信號(hào)讀數(shù)低于通道配置數(shù)據(jù)中的預(yù)定水平時(shí)，將顯示欠量程故障消息。通常，這是由于傳感器或傳感器電纜安裝開路造成的。
The EEPROM holds the application configuration data.
The EEPROM failure message is displayed if there is a checksum difference or it has been impossible to carry out a checksum test during start-up or periodic self test. This is a serious card failure and, as such, the card needs to be replaced.Vps is a voltage which is used to set the absolute value reference for the reading scaling factor. The no Vps message is displayed on a channel card that has not been factory tested. This is a serious card failure and, as such, the card needs to be replaced.The Vps plug-in is used to set the Vps reference and is not suitable for operating sensors. The Vps plug-in fitted message is a factory test message, when displayed indicates that a special module is fitted to the sensor drive module connections. Unless the card has been incorrectly supplied with a VP1 module fitted.This is a serious card failure and, as such, the card needs to be replaced.The current setting fault message is displayed if the channel card has failed to set the correct catalytic sensor bridge current during the startup routine. Check the sensor connection and cable line lengths to ensure that maximum line impedance has not been exceeded.The configuration fault message is displayed during start-up if the channel card has no configuration information or the configuration is not valid. This is a serious card failure and, as such, the card needs to be replaced.The wrong plug-in message is displayed during start-up if the actual sensor drive module fitted to the channel card is different from the type selected in the channel card configuration. The plug-in should be checked for compatibility with the sensor and either the plug-in module or channel card configuration changed accordingly
Error Code Meaning
High Integrity Relay Fault. The actual and demanding states of the high integrity relay outputs do not match. Check that the high integrity relay card is properly connected. If possible use another known working high integrity relay or control card to determine which card to replace.The hardware fault message is displayed if the channel card detects a fault in its operation or a fault with a sensor input. Check the sensor connections. Remove the channel card and insert it into a compatible working channel and check its operation (ER86 may appear during this operation - this is normal). If the card still indicates a fault, it must be replaced. If the card is working, the sensor should be replaced.Under Range Fault The under range fault message is displayed when the sensor signal reading is less than the predetermined level held within the channel configuration data. Typically this is due to either the sensor or the sensor cable installation being open circuit.
