TRICONEX 3381工业卡件系列介绍
卡在错误的插槽中如果通道卡已移动到与其校准过的插槽不同的插槽，则会显示错误插槽中的卡消息。这允许将卡移动到其他插槽位置以查找故障。当安装新的通道卡或备用更换件时，也可能显示此消息。通过将通道卡校准到新的插槽位置和连接的传感器，可以清除该消息。根据报警配置，将通道卡移动到其他插槽可能会影响报警的生成。移动和校准卡后，应检查报警操作。只有在检查传感器处于清洁（非目标气体）空气中后，才能重置锁定信号超范围故障条件。如果系统电源电压低于约16V dc，将显示电源故障错误消息。如果未启用电源故障延迟，则错误锁定。检查电源的工作情况。电源正确恢复后，检查系统的工作情况。Datasum Changed（数据量已更改）如果在正常操作期间通道卡RAM出现故障，则会显示数据量已改变消息。应通过断开卡的电源来重置卡。这是通过从机架插槽中取出卡，然后将卡装回机架插槽来实现的。如果错误消息仍然存在，则需要更换卡。当前设置故障（仅限催化传感器）当控制卡无法设置或保持催化传感器的正确工作电流时，将显示当前设置故障消息。检查传感器连接和电缆线路长度，确保未超过最大线路阻抗。
生命周期已过期
如果催化传感器灵敏度低于其原始值的50%，将显示寿命到期消息。寿命根据第一次SPAN期间测量的灵敏度与随后正常SPAN期间测得的灵敏度之间的差值计算，并且仅在SPAN功能期间更新。这是一个警告，说明传感器输出变得不可接受的低，可能是由于老化或传感器被硅酮、硫和铅化合物“中毒”。应更换传感器。信号低于范围当传感器信号读数低于通道配置数据中的预定水平时，显示信号低于范围消息。该预定水平低于正常工作范围。这通常是由于传感器信号漂移到正常零操作点以下。根据传感器类型，这可能是由于气候条件的巨大变化、端子连接松动、传感器中毒或传感器故障的早期迹象。在某些情况下，此错误可能由传感器或电缆短路引起。应校准通道卡并检查其操作。
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.
