系統(tǒng)應保持清潔，并保持自由防止灰塵和油脂。應每年進行以下檢查：，
如果當?shù)胤ㄒ?guī)或程序要求，則更頻繁：
（1） 檢查并在必要時擰緊直流輸入端的所有端子卡和接口/中繼卡。
（2） 檢查工程卡通電（）綠色LED是否為：點亮，所有其他LED熄滅。
（3） 檢查每個通道卡顯示是否指示正常讀數(shù)沒有錯誤消息。
（4） 依次選擇每個通道卡，并檢查通道傳感器信號讀數(shù)，如果連接了催化傳感器，則傳感器橋電流。
（5） 工程鑰匙安裝在工程卡上后，選擇每個通道卡依次進入報警測試功能。
（6） 檢查報警級別、報警LED操作、報警繼電器操作以及每個頻道的顯示操作。
（7） 檢查所有故障和禁止繼電器的工作情況。
（8） 檢查傳感器處于無氣體環(huán)境中時，顯示器表示零。如果適用，使用調(diào)整零點讀數(shù)零函數(shù)。
對于氧氣應用，應僅操作零點功能
在無氧氣氛中。正常大氣下
顯示器應顯示21%±0.5%v/v的條件，這可以是通過使用跨度函數(shù)進行調(diào)整。

The system should be maintained in a clean condition and kept free
from dust and grease. The following checks should be made annually,
or more frequently if required by local regulations or procedures:
(1) Check and if necessary tighten all terminations to the DC Input
Card and Interface/Relay Cards.
(2) Check that the Engineering Card power on ( ) green LED is
illuminated and all other LEDs are extinguished.
(3) Check that each channel card display indicates a normal reading
with no error messages.
(4) Select each channel card in turn and check that channels sensor
signal reading and, if a catalytic sensor is connected, the sensor
bridge current.
(5) With the Engineering Key fitted to the Engineering Card, select
each channel card in turn and enter the alarms test function.
(6) Check the alarm levels, alarm LED operation, alarm relay operation
and display operation for each channel.
(7) Check the operation of all fault and inhibit relays.
(8) Check that, with the sensor in a gas free atmosphere, the display
indicates zero. If appropriate adjust the zero reading using the
ZERO function.
Note: For oxygen applications the zero function should only be operated
in an oxygen free atmosphere. Under normal atmosphere
conditions the display should indicate 21% ± 0.5% v/v, this can be
adjusted by using the SPAN function.
The System 57 control cards and engineering cards carry out continual
self checking of the integrity of the hardware, software and sensor
operation. In the event of a problem, and depending on the type of
problem, the control card will indicate either an error message on the
LCD display or will operate the fault LED and relay output.
ERROR CODES
5.1 General
Operating errors within the system are indicated on the LCD message
display as an error code. The error codes used and their meaning are
listed in the following sections. These sections also contain appropriate
information pertaining to the likely cause of the error message being
displayed and an indication on how the error affects the operation of the
channel card.
Error Code: This relates to the error code message ERxx displayed on
the LCD message display. If more than one error is
present simultaneously, the error with the highest code
number is displayed.
