數(shù)字顯示
數(shù)字顯示器為四字符、七段顯示器提供傳感器氣體讀數(shù)指示或相關(guān)值從工程卡中選擇的功能。
根據(jù)傳感器范圍和配置設(shè)置，數(shù)字顯示器將氣體值顯示為無小數(shù)位（默認(rèn)設(shè)置）或小數(shù)點(diǎn)后一位。
2.2.4信息顯示信息顯示由四個字符、14段顯示組成其提供傳感器狀態(tài)或以下信息的智能報(bào)告：
選定的工程功能。對于安裝有high的控制卡完整性繼電器輸出執(zhí)行主、區(qū)域或表決報(bào)警，報(bào)警
狀態(tài)也將顯示如下：
光束-光束阻塞報(bào)警MSTR-主報(bào)警分區(qū)報(bào)警投票報(bào)警
如果發(fā)生更新警報(bào)，則更新原因如下所示：跟隨：-故障報(bào)警
-IN-Inhibit報(bào)警
-A1-A1報(bào)警
-A3-A2報(bào)警
-A3-A3報(bào)警
-ST-STEL報(bào)警器
-LT-LTEL報(bào)警
-實(shí)時率報(bào)警
2.2.5圖標(biāo)
圖標(biāo)提供了顯示器正在運(yùn)行的簡單指示，以及當(dāng)選擇通道卡以使用操作時更改工程卡。
發(fā)光二極管控制卡前面板上的五個LED指示操作
信道狀態(tài)如下：
a、 故障-琥珀色LED
故障指示燈在傳感器硬件出現(xiàn)故障時提供指示如果傳感器信號超出預(yù)定義限值或通道卡檢測到硬件或軟件故障。
b、 抑制-琥珀色LED禁止LED指示通道何時處于禁止?fàn)顟B(tài)。
這種情況可以手動和遠(yuǎn)程選擇，或發(fā)生自動：在啟動過程中，在大約30秒，當(dāng)執(zhí)行某些工程功能時，量程、第一量程和報(bào)警測試。根據(jù)配置，控制卡可能會進(jìn)入一段短時間內(nèi)的禁止模式故障條件被清除
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
