10.1.6報(bào)警
通電后，F(xiàn)CO101啟用了4個(gè)報(bào)警：?AIN1上110%的高報(bào)警
?AIN1上-10%的低報(bào)警
?AIN1和SETPT之間的110%偏差報(bào)警

1.按下報(bào)警/降壓按鈕，逐步通過(guò)報(bào)警限制和啟用/禁用狀態(tài)。注意所有報(bào)警被啟用，報(bào)警限值以工程單位顯示在數(shù)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(bào)警限值可以
可通過(guò)旋轉(zhuǎn)脈沖發(fā)生器旋鈕來(lái)改變。嘗試將報(bào)警限值A(chǔ)1更改為50%（300華氏度），然后按存儲(chǔ)以保存新值。
2.按退出返回正常操作模式。
3.進(jìn)入手動(dòng)模式以顯示Loop01.V。
4.轉(zhuǎn)動(dòng)脈沖發(fā)生器旋鈕，直到閥門(mén)輸出和過(guò)程輸入均大于50%。請(qǐng)注意字母數(shù)字顯示器將閃爍“A1高”，L和S LED將閃爍。
按確認(rèn)按鈕以確認(rèn)警報(bào)
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(zhuǎn)動(dòng)脈沖發(fā)生器旋鈕，將最后一位數(shù)字更改為5。顯示應(yīng)為“0.00005”
15.按左箭頭按鈕，直到顯示屏顯示“500.000”，然后按存儲(chǔ)。
16.按“上一步”。
17.轉(zhuǎn)動(dòng)脈沖發(fā)生器旋鈕或使用箭頭按鈕以顯示DPP。
18.按下“下一步”。請(qǐng)注意，“0.00”或2位小數(shù)是默認(rèn)值。轉(zhuǎn)動(dòng)脈沖發(fā)生器旋鈕以設(shè)置數(shù)字小數(shù)位數(shù)的0.0或在顯示器上顯示1位小數(shù)，然后按存儲(chǔ)按鈕。
19.按下步進(jìn)并轉(zhuǎn)動(dòng)脈沖發(fā)生器旋鈕或使用箭頭按鈕顯示ENGUNITS。
20.按下“下一步”。請(qǐng)注意，默認(rèn)單位為PRCT。
21.使用箭頭按鈕將閃爍光標(biāo)移動(dòng)到P之前的空間?，F(xiàn)在將脈沖發(fā)生器旋鈕轉(zhuǎn)到顯示“D”。使用箭頭按鈕移動(dòng)到下一個(gè)位置，并轉(zhuǎn)動(dòng)脈沖發(fā)生器旋鈕選擇“E”。重復(fù)直到顯示器讀數(shù)為華氏度，然后按下存儲(chǔ)按鈕。
22.按ENTER/EXIT CONF返回正常操作。嘗試顯示過(guò)程和設(shè)定點(diǎn)。請(qǐng)注意，它們現(xiàn)在以工程單位顯示，比例為100到500或在50%時(shí)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(diào)整到高于或低于50%（300華氏度）。請(qǐng)注意，報(bào)警將在不按的情況下清除
如果進(jìn)程下降到報(bào)警限值以下，確認(rèn)按鈕-死區(qū)。使用報(bào)警快速按鈕返回
報(bào)警限制A1為默認(rèn)值110%（540華氏度），然后按存儲(chǔ)保存。中引用的其他報(bào)警參數(shù)
報(bào)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.
