初始預(yù)啟動設(shè)置啟動原動機前，請閱讀整個程序。
額定轉(zhuǎn)速電位計是該系統(tǒng)中唯一的多轉(zhuǎn)電位計控制所有其他罐都是單圈的。小心不要轉(zhuǎn)動這些鍋已經(jīng)停不住了。
額定轉(zhuǎn)速
A、 將額定轉(zhuǎn)速電位計設(shè)置為最小值（完全逆時針方向）。
B、 將外部速度微調(diào)（如果使用）設(shè)置到中間位置。
2.在中間位置復位設(shè)置。
3.增益設(shè)置在中間位置。
4.斜坡時間設(shè)置為最大值（完全順時針方向，注意不要過度扭轉(zhuǎn)鍋）。
5.將低怠速設(shè)置為最大值（完全順時針方向，注意不要過度扭轉(zhuǎn)鍋）。
6.負載增益設(shè)置在中間位置。
7.將下垂設(shè)置為最小值（完全逆時針方向，注意不要過度扭轉(zhuǎn)鍋）。
8.致動器補償。
A、 將執(zhí)行器補償電位計設(shè)置為0至上的2
10柴油、燃氣輪機或燃油噴射汽油電位計刻度原動機。
B、 將執(zhí)行器補償電位計設(shè)置為0至6
10用于汽化氣體或汽油原動機的電位計刻度，以及蒸汽渦輪機。
9.啟動燃油限制設(shè)置為最大值（完全順時針方向，注意不要過度扭轉(zhuǎn)鍋）。
10.確保致動器連接至端子20和21。
啟動調(diào)整
1.完成第2章中的安裝檢查程序，并完成初始上述預(yù)啟動設(shè)置。確保速度范圍開關(guān)設(shè)置在正確的速度范圍內(nèi)：您的應(yīng)用程序如第2章所述。手冊82389 2301A LSSC伍德沃德15
2.閉合額定觸點的閉合。將控件設(shè)置為“同步”通過閉合下垂觸點進行操作。
這僅用于初始原動機啟動。對于正常啟動額定觸點閉合（怠速時斷開/額定時閉合）應(yīng)為：如果原動機以怠速啟動，則打開。
3.向控制器施加輸入功率。
4.預(yù)設(shè)額定轉(zhuǎn)速。如果未使用信號發(fā)生器，將額定轉(zhuǎn)速電位計設(shè)置為最小值（完全逆時針）。
使用信號發(fā)生器設(shè)置額定轉(zhuǎn)速時，設(shè)置信號發(fā)生器額定轉(zhuǎn)速下轉(zhuǎn)速傳感器的頻率，并將其連接到端子28和29.（以Hz為單位的額定轉(zhuǎn)速頻率等于額定轉(zhuǎn)速原動機轉(zhuǎn)速（rpm）乘以轉(zhuǎn)速傳感器上的齒數(shù)齒輪除以60。）將額定觸點的閉合置于額定（閉合）位置位置將速度微調(diào)電位計（如果使用）設(shè)置到中間位置。連接將直流模擬電壓表連接到端子20（+）和21（-），以讀取致動器電壓。
如果執(zhí)行器電壓為最小值（最小值約為0伏特），順時針緩慢轉(zhuǎn)動額定轉(zhuǎn)速電位計（對于反向作用控制，逆時針方向）直到電壓剛開始移動到最大值。
如果執(zhí)行器電壓處于最大值，則緩慢轉(zhuǎn)動額定轉(zhuǎn)速電位計逆時針方向（逆時針方向用于反向控制）直到電壓剛開始移動到最小值。
Initial Pre-Start Settings
Read this entire procedure before starting the prime mover.
The Rated Speed potentiometer is the only multi-turn pot in this
control. All other pots are single-turn. Take care not to turn these
pots beyond their stops.
1. RATED SPEED
A. Set the RATED SPEED potentiometer to minimum (fully
counterclockwise).
B. Set the external Speed Trim, if used, to mid-position.
2. RESET—Set at mid-position.
3. GAIN—Set at mid-position.
4. RAMP TIME—Set at maximum (fully clockwise—be careful not to
overtorque the pot).
5. LOW IDLE SPEED—Set at maximum (fully clockwise—be careful not to
overtorque the pot).
6. LOAD GAIN—Set at mid-position.
7. DROOP—Set at minimum (fully counterclockwise—be careful not to
overtorque the pot).
8. ACTUATOR COMPENSATION.
A. Set the ACTUATOR COMPENSATION potentiometer at 2 on the 0 to
10 potentiometer scale for diesel, gas turbine, or fuel-injected gasoline
prime movers.
B. Set the ACTUATOR COMPENSATION potentiometer at 6 on the 0 to
10 potentiometer scale for carbureted-gas or gasoline prime movers,
and steam turbines.
9. START FUEL LIMIT—Set at maximum (fully clockwise—be careful not to
overtorque the pot).
10. Be sure that the actuator is connected to terminals 20 and 21.
Start-Up Adjustments
1. Complete the installation checkout procedure in Chapter 2, and the initial
prestart settings above.
Be sure the speed range switch is set on the right speed range for
your application as described in Chapter 2.

2. Close the Close For Rated contact. Set the control for isochronous
operation by closing the droop contact.
This is for initial prime mover start-up only. For normal start-up, the
Close For Rated contact (open for idle/close for rated) should be
open if the prime mover is to start at idle.
3. Apply input power to the control.
4. Preset rated speed.
If a signal generator is not used, set the RATED SPEED potentiometer at
minimum (fully counterclockwise).
When using a signal generator to set rated speed, set the signal generator
for the frequency of the speed sensor at rated speed, and connect it to
terminals 28 and 29. (The rated speed frequency in Hz equals the rated
prime mover speed in rpm times the number of teeth on the speed-sensing
gear divided by 60.) Put the Close For Rated contact in the rated (closed)
position. Set the speed trim potentiometer, if used, to mid-position. Connect
a dc analog voltmeter to terminals 20 (+) and 21 (–) to read actuator voltage.
If the actuator voltage is at minimum (minimum will be approximately 0
volts), slowly turn the RATED SPEED potentiometer clockwise
(counterclockwise for reverse-acting controls) until the voltage just begins to
move to maximum.
If the actuator voltage is at maximum, slowly turn the RATED SPEED
potentiometer counterclockwise (clockwise for reverse-acting controls) until
the voltage just begins to move to minimum.
