欠量程故障將顯示范圍不足故障信息
當傳感器信號讀數小于通道內保持的預定電平配置數據。
通常,這是由于傳感器或傳感器電纜安裝斷路。
87超范圍故障將出現超出范圍故障消息
當傳感器信號讀數高于信道內保持的預定電平配置數據。
通常,這是由于傳感器或傳感器電纜安裝短路。或者,傳感器可以檢測氣體含量非常高。鎖存信號的復位超出范圍只能執行故障條件檢查傳感器是否清潔后(非目標氣體)空氣。
86卡在錯誤的插槽中
卡在錯誤的插槽中。消息為:如果頻道卡已被已移動到與該插槽不同的插槽
它已經被校準。這允許將卡移動到用于故障查找的替代插槽位置
目的。此消息也可能是:安裝新頻道卡時顯示或安裝備用替換件。這個
可通過校準清除消息將通道卡移動到新插槽位置并連接傳感器。
根據警報配置,將通道卡移動到替代插槽
可能會影響生成警報。報警操作應為:移動卡后檢查并校準。
85電源故障錯誤
將顯示電源故障錯誤消息如果系統電源電壓低于
大約16V dc。錯誤鎖存器如果未啟用電源故障延遲。
檢查電源的工作情況。
當電力被正確恢復時,檢查系統的運行情況。
84數據集已更改數據集更改消息為:
如果通道中出現故障,則顯示正常操作期間的卡RAM。
應通過移除來重置卡卡的電源。這是實現的從機架插槽中卸下板卡
然后將卡放回機架插槽。如果錯誤消息仍然存在這張卡需要更換。
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.
