FBM222输入输出模块
10.1.6报警
通电后，FCO101启用了4个报警：•AIN1上110%的高报警
•AIN1上-10%的低报警
•AIN1和SETPT之间的110%偏差报警
•无警报
1.按下报警/降压按钮，逐步通过报警限制和启用/禁用状态。注意所有报警被启用，报警限值以工程单位显示在数字显示器上，并作为S条形图上闪烁LED的范围百分比。如果满足安全许可，报警限值可以
可通过旋转脉冲发生器旋钮来改变。尝试将报警限值A1更改为50%（300华氏度），然后按存储以保存新值。
2.按退出返回正常操作模式。
3.进入手动模式以显示Loop01.V。
4.转动脉冲发生器旋钮，直到阀门输出和过程输入均大于50%。请注意字母数字显示器将闪烁“A1高”，L和S LED将闪烁。
按确认按钮以确认警报
12.按“向下”键显示“100.000”。
13.按下向右箭头按钮，直到显示屏显示“0.00001”。
14.转动脉冲发生器旋钮，将最后一位数字更改为5。显示应为“0.00005”
15.按左箭头按钮，直到显示屏显示“500.000”，然后按存储。
16.按“上一步”。
17.转动脉冲发生器旋钮或使用箭头按钮以显示DPP。
18.按下“下一步”。请注意，“0.00”或2位小数是默认值。转动脉冲发生器旋钮以设置数字小数位数的0.0或在显示器上显示1位小数，然后按存储按钮。
19.按下步进并转动脉冲发生器旋钮或使用箭头按钮显示ENGUNITS。
20.按下“下一步”。请注意，默认单位为PRCT。
21.使用箭头按钮将闪烁光标移动到P之前的空间。现在将脉冲发生器旋钮转到显示“D”。使用箭头按钮移动到下一个位置，并转动脉冲发生器旋钮选择“E”。重复直到显示器读数为华氏度，然后按下存储按钮。
22.按ENTER/EXIT CONF返回正常操作。尝试显示过程和设定点。请注意，它们现在以工程单位显示，比例为100到500或在50%时为300。按下“单位”按钮以显示上面配置的工程单位。尝试将工艺调整到高于或低于50%（300华氏度）。请注意，报警将在不按的情况下清除
如果进程下降到报警限值以下，确认按钮-死区。使用报警快速按钮返回
报警限制A1为默认值110%（540华氏度），然后按存储保存。中引用的其他报警参数
报警功能块描述可以以类似方式改变。
10.1.6 Alarms
Upon power up, FCO101 has 4 alarms enabled:
• Hi alarm at 110% on AIN1
• Lo alarm at -10% on AIN1
• Deviation alarm of 110% between AIN1 and SETPT
• No alarm
1. Press the ALARM/STEP DOWN button to step through the Alarm limits and Enable/Disable Status. Notice all
the alarms are enabled and the alarm limits are displayed in engineering units on the numeric display and as a
percentage of range by a flashing LED on the S bargraph. If security clearance is satisfied, the alarm limits can
be changed by rotating the pulser knob. Try changing the alarm limit A1 to 50% (300 DEG F) and press
STORE to save the new value.
2. Press EXIT to return to normal operation mode.
3. Enter manual mode to display Loop01.V.
4. Turn the pulser knob until both the valve output and process input are greater than 50%. Note that the
alphanumeric display will flash “A1 HI” and the L and S LEDs will flash. Press the ACK button to
acknowledge the alarm. 12. Press STEP DOWN to display “100.000”.
13. Press the right arrow button until display reads “0.00001”.
14. Turn the pulser knob to change the last digit to 5. Display should read “0.00005”
15. Press left arrow button until display reads “500.000” and press store.
16. Press STEP UP.
17. Turn the pulser knob or the use arrow button to display DPP.
18. Press STEP DOWN. Notice “0.00” or 2 decimal places is the default. Turn the pulser knob to set the number
of decimal places to 0.0 or to show 1 decimal place on the display and press STORE button.
19. Press STEP UP and turn the pulser knob or use the arrow button to display ENGUNITS.
20. Press STEP DOWN. Notice that the default units are PRCT.
21. Use the arrow buttons to move the flashing cursor to the space before the P. Now turn the pulser knob to
display “D”. Use the arrow button to move to the next position and turn the pulser knob to select “E”. Repeat
until display reads DEG F and press the STORE button.
22. Press ENTER/EXIT CONF to return to normal operation.
Try displaying the process and setpoint. Notice that these are now displayed in engineering units scaled 100 to 500
DEG F, or 300 at 50%. Press the UNITS button to display the engineering units configured above. Try adjusting the process above and below 50% (300 DEG F). Notice that the alarm will clear without pressing the
ACK button if the process drops below the alarm limit - deadband. Use the ALARM QUICK button to return the
Alarm Limit A1 to the default 110% (540 DEG F) and press STORE to save. Other alarm parameters referenced in
the ALARM function block description may be changed in a similar manner.
