电流设置故障（催化传感器仅限）
当前设置故障信息为：当控制卡无法执行以下操作时显示：
设置或保持正确的工作电流用于催化传感器。
检查传感器连接和电缆线路确保最大线的长度未超过阻抗。
82寿命到期如果出现以下情况，将显示生存期过期消息：
催化传感器灵敏度降至以下其原始价值的50%。
寿命是根据差值计算的在第1次测量期间测量的灵敏度之间跨度和随后测量的跨度
正常跨度，仅在跨度函数。
这是传感器输出为的警告变得不可接受的低，可能是由于老化或由于传感器“中毒”
通过硅酮、硫和铅化合物。应更换传感器。
81信号低于范围
显示信号低于范围信息当传感器信号读数小于通道内保持的预定电平
配置数据。这个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低于正常零操作点。
根据传感器类型，由于气候的巨大变化条件、端子连接松动、传感器中毒或早期指示传感器的故障。在某些情况下，此错误可能是：由传感器短路或布线。
应校准通道卡并检查其操作。80信号超范围
信号超出范围警告信息为：当传感器信号读数为超过预定水平，保持在信道配置数据。这预定水平高于操作水平范围
这提供了传感器处于以下状态的警告：
检测到气体水平超过设定值信道的工作范围。
锁存信号的复位超出范围警告条件只能执行检查传感器是否清洁后（非目标气体）空气。
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.
82 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.
81 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.
80 Signal Over Range
The signal over range warning message is
displayed when the sensor signal reading is
more than a predetermined level held within
the channel configuration data. This
predetermined level is above the operating
range.
This provides a warning that the sensor is
detecting a level of gas exceeding the set
operating range of the channel.
The reset of a latched signal overrange
warning condition should only be carried out
after checking that the sensor is in clean
(non target gas) air.
