電流設(shè)置故障（催化傳感器僅限）
當(dāng)前設(shè)置故障信息為：當(dāng)控制卡無法執(zhí)行以下操作時(shí)顯示：
設(shè)置或保持正確的工作電流用于催化傳感器。
檢查傳感器連接和電纜線路確保最大線的長度未超過阻抗。
82壽命到期如果出現(xiàn)以下情況，將顯示生存期過期消息：
催化傳感器靈敏度降至以下其原始價(jià)值的50%。
壽命是根據(jù)差值計(jì)算的在第1次測量期間測量的靈敏度之間跨度和隨后測量的跨度
正常跨度，僅在跨度函數(shù)。
這是傳感器輸出為的警告變得不可接受的低，可能是由于老化或由于傳感器“中毒”
通過硅酮、硫和鉛化合物。應(yīng)更換傳感器。
81信號低于范圍
顯示信號低于范圍信息當(dāng)傳感器信號讀數(shù)小于通道內(nèi)保持的預(yù)定電平
配置數(shù)據(jù)。這個(gè)預(yù)定水平低于正常工作范圍。
這通常是由于傳感器信號漂移低于正常零操作點(diǎn)。
根據(jù)傳感器類型，由于氣候的巨大變化條件、端子連接松動、傳感器中毒或早期指示傳感器的故障。在某些情況下，此錯(cuò)誤可能是：由傳感器短路或布線。
應(yīng)校準(zhǔn)通道卡并檢查其操作。80信號超范圍
信號超出范圍警告信息為：當(dāng)傳感器信號讀數(shù)為超過預(yù)定水平，保持在信道配置數(shù)據(jù)。這預(yù)定水平高于操作水平范圍
這提供了傳感器處于以下狀態(tài)的警告：
檢測到氣體水平超過設(shè)定值信道的工作范圍。
鎖存信號的復(fù)位超出范圍警告條件只能執(zhí)行檢查傳感器是否清潔后（非目標(biāo)氣體）空氣。
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.
