要查看漸變率的工作方式,請確??刂破魈幱谧詣幽J剑?zhí)行以下步驟。
1.按快速顯示RRATE。
2.旋轉(zhuǎn)脈沖發(fā)生器旋鈕,將斜坡速率設(shè)置為300,然后按存儲。由于SETPT范圍指針為對于按100至500華氏度縮放的AIN1,300將表示300華氏度/分鐘的斜坡速率。
3.按快速鍵顯示目標(biāo)。將目標(biāo)設(shè)置為250%,然后按存儲。
4.按快速鍵顯示R ON OFF。轉(zhuǎn)動脈沖發(fā)生器旋鈕將設(shè)置更改為ON,然后按存儲。
5.按ENTER/EXIT在數(shù)字顯示器上顯示設(shè)定點。設(shè)定點應(yīng)在30分鐘內(nèi)上升至25%秒。
要從漸變速率更改為漸變時間,請執(zhí)行以下步驟。
1.按ENTER/EXIT CONF以顯示循環(huán)。
2.按兩次“向下”以顯示視圖。
3.按下向右箭頭按鈕或轉(zhuǎn)動脈沖發(fā)生器旋鈕以顯示編輯FB。
4.按“向下”鍵顯示A/M。
5.轉(zhuǎn)動脈沖發(fā)生器旋鈕以顯示SETPT。
6.按下“下一步”以顯示RG PTR。
轉(zhuǎn)動脈沖發(fā)生器旋鈕以顯示使用率。
8.按“向下”鍵顯示“是”。
9.將脈沖發(fā)生器旋鈕轉(zhuǎn)到“否”,然后按存儲。按“上一步”。
10.逆時針轉(zhuǎn)動脈沖發(fā)生器旋鈕或使用左箭頭按鈕顯示RTIME。11.按下“逐步下降”以顯示斜坡時間。
12.轉(zhuǎn)動脈沖發(fā)生器旋鈕以設(shè)置所需的斜坡時間,然后按存儲。
13.按退出返回正常操作模式。

10.1.9調(diào)諧
在正常操作模式下,按下調(diào)諧按鈕將滾動控制器調(diào)諧參數(shù)和允許激活自動調(diào)諧算法。FCO101配置為具有自動調(diào)諧功能的PID控制啟用。按下調(diào)諧按鈕,并注意比例增益(PG)、時間積分(TI)的默認(rèn)值,
將顯示時間導(dǎo)數(shù)(TD)和導(dǎo)數(shù)增益(DG)。此外,自動調(diào)諧參數(shù)%將顯示偏差百分比、滯后和自動調(diào)諧是/否。
To see how the Ramp rate works, make sure the controller is in AUTO mode and do the following steps.
1. Press QUICK to display RRATE.
2. Rotate the pulser knob to set the ramp RATE to 300 and press STORE. Since the SETPT range pointer is
configured for AIN1 scaled 100 to 500 DEG F, 300 will represent a ramp rate of 300 DEG F/min.
3. Press QUICK to display TARGET. Set the target to 250% and press STORE.
4. Press QUICK to display R ON OFF. Turn the pulser knob to change the setting to ON and press STORE.
5. Press ENTER/EXIT to display the setpoint on the numeric display. The setpoint should ramp to 25% in 30
seconds.
To change from a Ramp RATE to a Ramp TIME do the following steps.
1. Press ENTER/EXIT CONF to display LOOP.
2. Press STEP DOWN twice to display VIEW.
3. Press the right arrow button or turn the pulser knob to display EDIT FB.
4. Press STEP DOWN to display A/M.
5. Turn the pulser knob to display SETPT.
6. Press STEP DOWN to display RG PTR.
7. Turn the pulser knob to display USE RATE.
8. Press STEP DOWN to display YES.
9. Turn the pulser knob to change to NO, and press STORE. Press STEP UP.
10. Turn pulser knob counterclockwise or use left arrow button to display RTIME. 11. Press STEP DOWN to display ramp TIME.
12. Turn the pulser knob to set the desired Ramp TIME, and press STORE.
13. Press EXIT to return to normal operation mode.
Now press the QUICK button. Note that the RTIME parameter will now be displayed instead of the RRATE
parameter. Setting R ON OFF parameter to “ON” will now ramp the setpoint to the TARGET setpoint in the
specified time rather that at a particular rate. See the SETPT description in Section 3.2 for more details on setpoint
functions.
Quickset parameters for other function blocks such as RATIO and BIAS may be changed in a similar fashion. See
specific function block descriptions in Section 3 for more details.
10.1.9 TUNE
When in normal operation mode, pressing the TUNE button will scroll through the controller tuning parameters and
allow activating the AUTOTUNE algorithm. FCO101 is configured for PID control with the AUTOTUNE feature
enabled. Press the TUNE button and note that the default values for Proportional Gain (PG), Time-Integral (TI),
Time-Derivative (TD), and the Derivative Gain (DG) will be displayed. In addition, the AUTOTUNE parameters
% Deviation, % Hysteresis, and Autotune YES/NO will be displayed.
