数字显示
数字显示器为四字符、七段显示器提供传感器气体读数指示或相关值从工程卡中选择的功能。
根据传感器范围和配置设置，数字显示器将气体值显示为无小数位（默认设置）或小数点后一位。
2.2.4信息显示信息显示由四个字符、14段显示组成其提供传感器状态或以下信息的智能报告：
选定的工程功能。对于安装有high的控制卡完整性继电器输出执行主、区域或表决报警，报警
状态也将显示如下：
光束-光束阻塞报警MSTR-主报警分区报警投票报警
如果发生更新警报，则更新原因如下所示：跟随：-故障报警
-IN-Inhibit报警
-A1-A1报警
-A3-A2报警
-A3-A3报警
-ST-STEL报警器
-LT-LTEL报警
-实时率报警
2.2.5图标
图标提供了显示器正在运行的简单指示，以及当选择通道卡以使用操作时更改工程卡。
发光二极管控制卡前面板上的五个LED指示操作
信道状态如下：
a、 故障-琥珀色LED
故障指示灯在传感器硬件出现故障时提供指示如果传感器信号超出预定义限值或通道卡检测到硬件或软件故障。
b、 抑制-琥珀色LED禁止LED指示通道何时处于禁止状态。
这种情况可以手动和远程选择，或发生自动：在启动过程中，在大约30秒，当执行某些工程功能时，量程、第一量程和报警测试。根据配置，控制卡可能会进入一段短时间内的禁止模式故障条件被清除
Digital Display
The digital display is a four character, seven segment display which
provides either an indication of the sensor gas reading or a value relating
to a function selected from the Engineering Card.
Depending on the sensor range and the configuration setting, the digital
display shows a gas value to either no decimal place (the default setting)
or to one decimal place.
2.2.4 Message Display
The message display consists of a four character, 14 segment display
which provides intelligent reporting of the sensor status or information on
a selected engineering function. For control cards fitted with the high
integrity relay outputs performing master, zone or voted alarms, the alarm
state will also be indicated as follows:
BEAM - Beam Blocked Alarm
MSTR - Master Alarm
ZONE - Zoned Alarm
VOTE - Voted Alarm
In the case of an Update alarm the cause of the update is indicated as
follows:
-FT- - Fault Alarm
-IN- - Inhibit Alarm
-A1- - A1 alarm
-A3- - A2 alarm
-A3- - A3 alarm
-ST- - STEL alarm
-LT- - LTEL alarm
-RT- - Rate alarm
2.2.5 Icon
The icon provides a simple indication that the display is functioning and
changes when the channel card is selected for operation with the
Engineering Card.
LEDS
Five LEDs on the front panel of the control card indicate the operational
status of the channel as follows:
a. FAULT - Amber LED
The fault LED provides an indication in the event of a sensor hardware
failure, if the sensor signal is outside pre-defined limits or if the
channel card has detected a hardware or software fault.
b. INHIBIT - Amber LED
The inhibit LED indicates when the channel is in the inhibit condition.
This condition can be selected manually and remotely, or occurs
automatically:
during start-up for a pre-defined period of approximately 30
seconds,
when carrying out certain engineering functions such as zero,
span, 1st span and alarm test.
Depending upon the configuration, the control card may enter
the inhibit mode for a short period of time immediately after a
fault condition is cleared
