3BHE036342R0101 DCS卡件
3.3.7珠子mA按钮当操作胎圈mA按钮时，所选的
催化控制卡提供该卡传感器头的指示
现在的如果工程关键是：安装在工程卡上。报警按钮当操作报警按钮时，所选的
控制卡提供该卡的级别和类型指示（上升或下降）的每个报警电平（A1、A2、A3、STEL、LTEL）。
如果工程钥匙安装在工程卡上，调整可以在预先定义的限制范围内达到报警水平，并且测试设施可用。该设施允许每次报警操作
待检查，如果需要，其相关输出继电器应：锻炼。
3.3.9信号按钮
当操作信号按钮时，所选控制卡提供该卡传感器信号的指示：
跟随：a、 4-20mA控制卡-回路电流（mA）。
b、 催化控制卡-催化桥输出（灵敏度），单位为mV。
3.3.10归零按钮
零点按钮只能在工程键处于以下状态时使用：
安装在工程卡上，用于校准选定的控制卡。
3.3.11量程按钮
只有在工程键为安装在工程卡上，用于校准选定的控制卡。
3.3.12第1跨按钮第1跨按钮只能在工程
钥匙安装在工程卡上，用于校准量程安装到选定催化控制装置的新催化传感器的点卡片
该功能用于提供指示，与随后的正常量程调整，a的输出灵敏度催化传感器，并自动指示中毒或损失传感器性能。3.3.13时钟按钮
当操作时钟按钮时，所选的控制卡提供机架的时间和日期指示时钟
3.3.7 BEAD mA Push-button
When the BEAD mA push-button is operated, the display of the selected
Catalytic Control Card provides an indication of that card's sensor head
current.
Adjustments to this current can also be made if the Engineering Key is
fitted to the Engineering Card.ALARMS Push-button
When the ALARMS push-button is operated, the display of the selected
control card provides an indication of that card's level and type (rising
or falling) of each alarm level (A1, A2, A3, STEL, LTEL).
If the Engineering Key is fitted to the Engineering Card, adjustments
can be made to the alarm levels, within pre-defined limits, and additional
test facilities become available. This facility allows each alarm operation
to be checked and, if required, its associated output relay to be
exercised.
3.3.9 SIGNAL Push-button
When the SIGNAL push-button is operated, the display of the selected
control card provides an indication of that cards sensor signal as
follows:
a. 4 - 20mA Control Card - Loop current in mA.
b. Catalytic Control Card - Catalytic bridge output (sensitivity) in mV.
3.3.10 ZERO Push-button
The ZERO push-button can only be used when the Engineering Key is
fitted to the Engineering Card and is used to calibrate the zero point of
the selected control card.
3.3.11 SPAN Push-button
The SPAN push-button can only be used when the Engineering Key is
fitted to the Engineering Card and is used to calibrate the span point of
the selected control card.
3.3.12 1ST SPAN Push-button
The 1ST SPAN push-button can only be used when the Engineering
Key is fitted to the Engineering Card and is used to calibrate the span
point of a new catalytic sensor fitted to a selected catalytic control
card.
This function is used to provide an indication, in conjunction with
subsequent normal span adjustments, of the output sensitivity of a
catalytic sensor and to automatically indicate poisoning or loss of
sensor performance.
3.3.13 CLOCK Push-button
When the CLOCK push-button is operated, the display of the selected
control card provides an indication of the time and date of the rack
clock.
