如果存在校驗和差異，或者在啟動或定期自檢期間無法執行校驗和測試，則會顯示EEPROM故障消息。這是一個嚴重的卡故障，因此需要更換卡。Vps是用于設置讀數比例因子絕對值參考的電壓。無Vps消息顯示在未經出廠測試的通道卡上。這是一個嚴重的卡故障，因此需要更換卡。Vps插件用于設置Vps參考，不適合操作傳感器。Vps plug-in fitted（Vps插件已安裝）消息是一條出廠測試消息，顯示時表示傳感器驅動模塊連接已安裝特殊模塊。除非卡未正確配備VP1模塊。這是一個嚴重的卡故障，因此需要更換卡。如果通道卡在啟動程序中未能設置正確的催化傳感器電橋電流，則會顯示當前設置故障消息。檢查傳感器連接和電纜線路長度，以確保未超過最大線路阻抗。如果通道卡沒有配置信息或配置無效，則會在啟動期間顯示配置故障消息。這是一個嚴重的卡故障，因此需要更換卡。如果安裝在通道卡上的實際傳感器驅動模塊與通道卡配置中選擇的類型不同，則在啟動過程中會顯示錯誤的插件消息。應檢查插件與傳感器的兼容性，并相應更改插件模塊或通道卡配置
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.
