TRICONEX 3381工業卡件系列介紹
卡在錯誤的插槽中如果通道卡已移動到與其校準過的插槽不同的插槽，則會顯示錯誤插槽中的卡消息。這允許將卡移動到其他插槽位置以查找故障。當安裝新的通道卡或備用更換件時，也可能顯示此消息。通過將通道卡校準到新的插槽位置和連接的傳感器，可以清除該消息。根據報警配置，將通道卡移動到其他插槽可能會影響報警的生成。移動和校準卡后，應檢查報警操作。只有在檢查傳感器處于清潔（非目標氣體）空氣中后，才能重置鎖定信號超范圍故障條件。如果系統電源電壓低于約16V dc，將顯示電源故障錯誤消息。如果未啟用電源故障延遲，則錯誤鎖定。檢查電源的工作情況。電源正確恢復后，檢查系統的工作情況。Datasum Changed（數據量已更改）如果在正常操作期間通道卡RAM出現故障，則會顯示數據量已改變消息。應通過斷開卡的電源來重置卡。這是通過從機架插槽中取出卡，然后將卡裝回機架插槽來實現的。如果錯誤消息仍然存在，則需要更換卡。當前設置故障（僅限催化傳感器）當控制卡無法設置或保持催化傳感器的正確工作電流時，將顯示當前設置故障消息。檢查傳感器連接和電纜線路長度，確保未超過最大線路阻抗。
生命周期已過期
如果催化傳感器靈敏度低于其原始值的50%，將顯示壽命到期消息。壽命根據第一次SPAN期間測量的靈敏度與隨后正常SPAN期間測得的靈敏度之間的差值計算，并且僅在SPAN功能期間更新。這是一個警告，說明傳感器輸出變得不可接受的低，可能是由于老化或傳感器被硅酮、硫和鉛化合物“中毒”。應更換傳感器。信號低于范圍當傳感器信號讀數低于通道配置數據中的預定水平時，顯示信號低于范圍消息。該預定水平低于正常工作范圍。這通常是由于傳感器信號漂移到正常零操作點以下。根據傳感器類型，這可能是由于氣候條件的巨大變化、端子連接松動、傳感器中毒或傳感器故障的早期跡象。在某些情況下，此錯誤可能由傳感器或電纜短路引起。應校準通道卡并檢查其操作。
Card In Wrong Slot
The card in wrong slot message is displayed if a channel card has been moved to a different slot from the one that it had been calibrated for. This allows cards to be moved to alternative slot locations for fault finding purposes. This message may also be displayed when fitting a new channel card or fitting a spare replacement. The message can be cleared by calibrating the channel card to the new slot location and connected sensor. Depending on the alarm configuration, moving channel cards to alternative slots may compromise the generation of alarms. The alarm operation should be checked after the card has been moved and calibrated.The reset of a latched signal overrange fault condition should only be carried out after checking that the sensor is in clean (non target gas) air.The power fail error message is displayed if the system supply voltage falls below approximately 16V dc. The error latches if power failure delay is not enabled. Check the operation of the power supply. When the power is correctly restored, check operation of system.Datasum Changed The datasum changed message is displayed if there is a failure in the channel card RAM during normal operation. The card should be reset by removing the power to the card. This is achieved by removing the card from the rack slot and then replacing the card back into the rack slot. If the error message persists the card needs replacing.Current Setting Fault (Catalytic Sensors Only) The current setting fault message is displayed when the control card is unable to set or maintain the correct operating current for a catalytic sensor. Check the sensor connection and cable line lengths to ensure that the maximum line impedance has not been exceeded.
Lifetime Expired
The lifetime expired message is displayed if the catalytic sensor sensitivity falls to below 50% of its original value. The lifetime is calculated on the difference between the sensitivity measured during 1st SPAN and that measured during subsequent normal SPANs, and is only updated during the SPAN function. This is a warning that the sensor output is becoming unacceptably low and may be due to age or due to the sensor being 'poisoned' by the presence of silicones, sulphur and lead compounds. The sensor should be replaced.Signal Under Range The signal under range message is displayed when the sensor signal reading is less than a predetermined level held within the channel configuration data. This predetermined level is below the normal operating range. This is typically due to the sensor signal drifting below the normal zero operating point. This could, depending on the sensor type, be due to large changes in climatic conditions, loose terminal connections, the sensor being poisoned or an early indication of the failure of the sensor.In some instances this error can be caused by short circuits in the sensor or cabling. The channel card should be calibrated and its operation checked.
