10.1.6報警
通電后，FCO101啟用了4個報警：?AIN1上110%的高報警
?AIN1上-10%的低報警
?AIN1和SETPT之間的110%偏差報警
?無警報
1.按下報警/降壓按鈕，逐步通過報警限制和啟用/禁用狀態。注意所有報警被啟用，報警限值以工程單位顯示在數字顯示器上，并作為S條形圖上閃爍LED的范圍百分比。如果滿足安全許可，報警限值可以
可通過旋轉脈沖發生器旋鈕來改變。嘗試將報警限值A1更改為50%（300華氏度），然后按存儲以保存新值。
2.按退出返回正常操作模式。
3.進入手動模式以顯示Loop01.V。
4.轉動脈沖發生器旋鈕，直到閥門輸出和過程輸入均大于50%。請注意字母數字顯示器將閃爍“A1高”，L和S LED將閃爍。
按確認按鈕以確認警報
12.按“向下”鍵顯示“100.000”。
13.按下向右箭頭按鈕，直到顯示屏顯示“0.00001”。
14.轉動脈沖發生器旋鈕，將最后一位數字更改為5。顯示應為“0.00005”
15.按左箭頭按鈕，直到顯示屏顯示“500.000”，然后按存儲。
16.按“上一步”。
17.轉動脈沖發生器旋鈕或使用箭頭按鈕以顯示DPP。
18.按下“下一步”。請注意，“0.00”或2位小數是默認值。轉動脈沖發生器旋鈕以設置數字小數位數的0.0或在顯示器上顯示1位小數，然后按存儲按鈕。
19.按下步進并轉動脈沖發生器旋鈕或使用箭頭按鈕顯示ENGUNITS。
20.按下“下一步”。請注意，默認單位為PRCT。
21.使用箭頭按鈕將閃爍光標移動到P之前的空間。現在將脈沖發生器旋鈕轉到顯示“D”。使用箭頭按鈕移動到下一個位置，并轉動脈沖發生器旋鈕選擇“E”。重復直到顯示器讀數為華氏度，然后按下存儲按鈕。
22.按ENTER/EXIT CONF返回正常操作。嘗試顯示過程和設定點。請注意，它們現在以工程單位顯示，比例為100到500或在50%時為300。按下“單位”按鈕以顯示上面配置的工程單位。嘗試將工藝調整到高于或低于50%（300華氏度）。請注意，報警將在不按的情況下清除
如果進程下降到報警限值以下，確認按鈕-死區。使用報警快速按鈕返回
報警限制A1為默認值110%（540華氏度），然后按存儲保存。中引用的其他報警參數
報警功能塊描述可以以類似方式改變。
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.
