UCD224A102通道模块
5701系列控制系统用于提供以下操作：以及全面维护天然气系统所需的工程设施检测设备。
机架系统内的每个控制卡显示传感器读数、报警该信道的状态和条件。
可以收集更多信息，并根据安全性状态，某些设置可以通过工程进行调整安装在机架上的卡。
系统的继电器输出配置为提供以下范围：
输出报警功能如下：
a、 故障报警当在控制卡中检测到故障时，故障报警激活并且不是用户可配置的。此外故障指示灯将点亮。
b、 抑制报警当系统报警被禁止时，禁止报警激活：任何原因，并且不可由用户配置。此外，禁止LED将被照亮。c、 A1、A2和A3级报警当气体液位下降时，A1、A2和A3液位报警激活被测量超过预配置的报警阈值。此外相关LED将点亮。
d、 STEL报警（短期暴露极限）当时间加权平均值有毒气体的浓度，通常平均超过10、15或30分钟，超过预先配置的阈值。激活时，STEL将：显示在控制卡的信息显示屏上。确切地继电器卡和配置，期间关联的报警LEDSTEL报警的设置将点亮，例如LTEL报警（长期暴露极限）。当时间加权平均值有毒气体的浓度，通常平均超过8小时预先配置的阈值。激活时，LTEL将显示在控制卡的消息显示。对于某些中继卡和配置，设置期间与LTEL相关的报警LED警报将点亮。
速率报警（仅限2Vx软件版本）
速率报警通过监测
传感器信号的上升速率，并提供早期报警指示
在传感器信号达到下一级报警设定点之前。
g、 单独报警
单个报警由单个控制器的输入引起
信道超过预先配置的阈值，与任何
另一个控制信道。相关LED（A1、A2、A3、故障、禁止）将
报警状态下控制卡上亮起。
INTRODUCTION
The 5701 Series Control System is equipped to provide the operational
and engineering facilities necessary to fully maintain a system of gas
detection equipment.
Each control card within a rack system displays a sensor reading, alarm
status and condition of that channel.
Further information can be gathered and, depending on the security
status, certain settings can be adjusted by means of an Engineering
Card fitted to the rack.
The relay outputs of the system are configured to provide a range of
output alarm functions as follows:
a. Fault Alarm
The fault alarm activates when a fault is detected in the control card
or associated sensor and is not user configurable. In addition the
FAULT LED will be illuminated.
b. Inhibit Alarm
The inhibit alarm activates when the system alarms are inhibited for
any reason and is not user configurable. In addition the INHIBIT LED
will be illuminated.
c. A1, A2 and A3 Level Alarms
The A1, A2 and A3 level alarms are activated when the level of gas
being measured crosses the preconfigured alarm threshold. In addition
the relevant LED will be illuminated.
d. STEL Alarm (Short Term Exposure Limit)
The STEL alarm will be activated when the time weighted average
concentration of a toxic gas, usually averaged over 10, 15 or 30
minutes, crosses a preconfigured threshold. When active STEL will
be shown on the message display of the control card. For certain
relay cards and configurations, the alarm LED associated during
setup to the STEL alarm will be illuminated.e. LTEL Alarm (Long Term Exposure Limit).
The LTEL alarm will be activated when the time weighted average
concentration of a toxic gas, usually averaged over 8 hours, crosses
a preconfigured threshold. When active LTEL will be shown on the
message display of the control card. For certain relay cards and
configurations, the alarm LED associated during setup to the LTEL
alarm will be illuminated.
f. Rate Alarm (Version 2Vx Software only)
The rate alarm predicts the future gas concentration by monitoring the
rate of rise of the sensor signal and provides an early alarm indication
before the sensor signal reaches the next level alarm set point.
g. Individual Alarm
An individual alarm is caused by the input to an individual control
channel crossing a preconfigured threshold and is not related to any
other control channel. The relevant LED (A1, A2, A3, Fault, Inhibit) will
illuminate on the control card with the alarm condition.
