UR6PH继电器模块
系统应保持清洁，并保持自由防止灰尘和油脂。应每年进行以下检查：，
如果当地法规或程序要求，则更频繁：
（1） 检查并在必要时拧紧直流输入端的所有端子卡和接口/中继卡。
（2） 检查工程卡通电（）绿色LED是否为：点亮，所有其他LED熄灭。
（3） 检查每个通道卡显示是否指示正常读数没有错误消息。
（4） 依次选择每个通道卡，并检查通道传感器信号读数，如果连接了催化传感器，则传感器桥电流。
（5） 工程钥匙安装在工程卡上后，选择每个通道卡依次进入报警测试功能。
（6） 检查报警级别、报警LED操作、报警继电器操作以及每个频道的显示操作。
（7） 检查所有故障和禁止继电器的工作情况。
（8） 检查传感器处于无气体环境中时，显示器表示零。如果适用，使用调整零点读数零函数。
对于氧气应用，应仅操作零点功能
在无氧气氛中。正常大气下
显示器应显示21%±0.5%v/v的条件，这可以是通过使用跨度函数进行调整。
系统57控制卡和工程卡连续执行硬件、软件和传感器完整性的自检
活动在出现问题时，取决于问题，控制卡将在LCD显示或将操作故障LED和继电器输出。
错误代码5.1概述系统内的操作错误显示在LCD消息上
显示为错误代码。使用的错误代码及其含义如下：在以下章节中列出。这些部分还包含适当的
与错误消息的可能原因有关的信息如下：显示并指示错误如何影响频道卡。
错误代码：这与上显示的错误代码消息ERxx有关LCD消息显示。如果存在多个错误：同时出现具有最高代码的错误显示数字。
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.
