有關HONEYWELL XCL8010A數字控制器的使用
單通道控制卡
提供必要的電源向相關傳感器供電并調節輸入傳感器信號接收到的傳感器信號
然后由微處理器及其結果值和任何必要的報警動作,取決于頻道進行配置。
通道卡前面板可以是:
分為五個區域:顯示標簽和封面。
液晶顯示器。
報警LED。
復位/選擇按鈕。提取槽。
LCD顯示連接的傳感器讀數及其狀態,或者如果需要維護在傳感器上執行時,有關傳感器設定點和校準數據。
顯示器可分為四個部分:
模擬顯示。
消息顯示
數字顯示。
圖標顯示。
2.2.2模擬顯示
這包括25個段,提供傳感器氣體讀數的指示形式為:覆蓋傳感器的模擬條形圖范圍在-10%和+110%fsd之間。
有兩種可能的操作模式:
a、 線段填充區域的實體在零和實際氣體讀數之間。
b、 單行,其中有一段指示實際氣體讀數。
這些模式中的每一種都可以作為上升或下降顯示。峰值讀取設備是:可用,其將段保持在最高,或傳感器獲得的最低氣體值,因為前一峰值讀數復位。這是一個有用的連接的行為記錄工具
傳感器默認操作模式為固態電流氣體具有峰值讀數功能的讀數顯示器。
The Single Channel Control Card
provides the necessary power
supplies to the associated sensor
and conditions the incoming sensor
signal. The received sensor signal
is then processed by the
microprocessor and the resultant
value and any necessary alarm
action, depending on the channel
configuration, is carried out.
The channel card front panel can be
subdivided into five areas:
Display Label and Cover.
LCD Display.
Alarm LEDs.
Reset/Select Push-button.
Extraction Slot.
The LCD provides a display of the connected
sensor reading and its status, or if maintenance is
being carried out on the sensor, information on the
sensor set points and calibration data.
The display can be divided into four parts:
Analogue Display.
Message Display
Digital Display.
Icon Display.
2.2.2 Analogue Display
This consists of 25 segments providing an
indication of the sensor gas reading in the form of
an analogue bar graph which covers the sensor
range between -10% and +110% fsd.
There are two possible modes of operation:
a. Solid in which the segments fill the area
between zero and the actual gas reading.
b. Single Line in which a single segment
indicates the actual gas reading.
Each of these modes can be operated as either a
rising or falling display. A peak reading facility is
available which maintains a segment at the highest,
or lowest, gas value obtained by the sensor since
the previous peak reading reset. This is a useful
recording tool for the behaviour of the connected
sensor.
The default mode of operation is solid current gas
reading display with a peak reading facility.
