欠量程故障将显示范围不足故障信息
当传感器信号读数小于通道内保持的预定电平配置数据。
通常，这是由于传感器或传感器电缆安装断路。
87超范围故障将出现超出范围故障消息
当传感器信号读数高于信道内保持的预定电平配置数据。
通常，这是由于传感器或传感器电缆安装短路。或者，传感器可以检测气体含量非常高。锁存信号的复位超出范围只能执行故障条件检查传感器是否清洁后（非目标气体）空气。
86卡在错误的插槽中
卡在错误的插槽中。消息为：如果频道卡已被已移动到与该插槽不同的插槽
它已经被校准。这允许将卡移动到用于故障查找的替代插槽位置
目的。此消息也可能是：安装新频道卡时显示或安装备用替换件。这个
可通过校准清除消息将通道卡移动到新插槽位置并连接传感器。
根据警报配置，将通道卡移动到替代插槽
可能会影响生成警报。报警操作应为：移动卡后检查并校准。
85电源故障错误
将显示电源故障错误消息如果系统电源电压低于
大约16V dc。错误锁存器如果未启用电源故障延迟。
检查电源的工作情况。
当电力被正确恢复时，检查系统的运行情况。
84数据集已更改数据集更改消息为：
如果通道中出现故障，则显示正常操作期间的卡RAM。
应通过移除来重置卡卡的电源。这是实现的从机架插槽中卸下板卡
然后将卡放回机架插槽。如果错误消息仍然存在这张卡需要更换。
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.
87 Over Range Fault
The over range fault message will appear
when the sensor signal reading is above the
predetermined level held within the channel
configuration data.
Typically this is due to either the sensor or the
sensor cable installation being short circuit.
Alternatively, the sensor may be detecting a
very high level of gas.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.
86 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.
85 Power Fail Error
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.
84 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.
