调整：与电压调节器有关的调整，以及以下段落中描述了系统操作，除了如有说明，在初始运行期间和正常情况下进行调整在电压调节器的寿命期间不必重复。
发电机电压调整变阻器（VAR）：此调整为用于控制发电机电压。设置为大值时逆时针位置，获得小发电机电压。
当变阻器设置为大顺时针位置。
标称电压范围设置调整（R2）：提供此调整
为了扩大发电机电压调整变阻器（VAR）的限制。通常，R2设置为向发电机电压调节变阻器提供：额定电压±10%的调节范围。R2位于监管者在尝试调整R2之前，松开1/2英寸锁紧螺母（用小螺丝刀）。调整后重新拧紧锁紧螺母完成
稳定性调整（R6）：稳定性控制R6提供稳定
通过控制反馈量来调节操作，即应用于误差检测器级。逆时针转动控制装置减少稳定性反馈量，使调节器反应更快。
该控制装置位于盖子顶部，安装在加热器下方下沉和高于范围调整。松开9/16英寸六角头锁紧螺母，防止控制轴在使用前因振动而转动尝试调整R6（使用螺丝刀）。之后重新拧紧锁紧螺母调整完成。
以额定频率、空载运行发电机稳定性调整是关键的。广告公正稳定 rst旋转使用螺丝刀完全顺时针控制。螺丝刀的一端插槽将指向2点钟；这一端是指针。设置稳定性逆时针旋转指针至10点钟。此设置正常确保良好的稳定性，但可能无法提供佳响应时间发电机。
如果发电机电压振荡（振荡），顺时针转动控制器
振荡停止的点。如果需要更快的响应，旋转逆时针控制，直到电压变得不稳定，以及然后顺时针旋转，直到电压稳定。佳调整当发电机电压稳定且响应令人满意时达到空载时，以及在任何负载下运行至满载时发电机的额定值。并联电压降电位计（R4）：提供此调整以控制并联运行的发电机的电压降信号。它位于调节器底盘上。达到大电压降当电位计设置到其大顺时针位置时。调整并联运行的每台发电机具有相同的电压降
如以下并行操作过程中所述。使使用1/2英寸扳手松开锁紧螺母进行调整，调整用螺丝刀将下垂，然后拧紧锁紧螺母已经进行了调整。
欠频调整（R55）：该调整包括在电压调节器提供了低频限制选项。R55是否在工厂按照以上所列或发电机的要求进行调整采购订单。
-当发电机频率可设置为所需的断点：
1.在电路板之间连接电压表端子TP1和TP2。
2.在所需的低频限值设置下运行发电机点（例如58Hz）。
3.根据仪表上的指示，将R55调整为0伏。
-发电机运行时调整低频限值频率无法调整。
1.在电路板之间连接电压表端子TP1（负）和TP2（正）。
2.在额定转速和电压下运行发电机。
3.确定所需的低频限值设定电压60Hz发电机见表1，50Hz发电机见表2发电机。
4.调整R55，直到TP1-TP2之间的电压等于测试适当表格中给出的电压。示例：带单位在60Hz下运行，并且其中期望在大约55Hz下限制，TP1-TP2两端的电压应为-0.438 Vdc。Adjustments: The adjustments pertaining to the voltage regulator and
system operation are described in the paragraphs that follow and, except
where noted, adjustment is made during initial operation and normally
does not have to be repeated during the life of the voltage regulator.
Generator voltage adjust rheostat (VAR): This adjustment is
provided to control the generator voltage. When set to its maximum
counterclockwise position, minimum generator voltage is obtained.
Maximum generator voltage is obtained when the rheostat is set to its
maximum clockwise position.
Nominal voltage range set adjust (R2): This adjustment is provided
to extend the limits of the generator voltage adjust rheostat (VAR).
Normally R2 is set to provide the generator voltage adjust rheostat with
an adjustment range of ±10% of rated voltage. R2 is located on the
regulator. Loosen the 1/2 inch locknut before attempting to adjust R2
(with a small screwdriver). Retighten the locknut after adjustment is
complete.
Stability adjustment (R6): Stability control R6 provides for stable
regulating operation by controlling the amount of feedback that is
ap plied to the error detector stage. Turning the control counterclockwise
decreases the amount of the stability feedback, making the regulator
respond faster.
This control is located on top of the cover, mounted below the heat
sink and above the RANGE adjust. Loosen the 9/16 inch hex-head
locknut that keeps the control shaft from turning due to vibration before
attempting to adjust R6 (with a screwdriver). Retighten the locknut after
adjustment is complete.
Operate the generator at rated frequency, no load, the point at which the
stability adjustment is most critical. Ad just STABILITY by  rst rotating
the control fully clockwise with screwdriver. One end of the screwdriver
slot will point to 2 oclock; this end is the pointer. Set the STABILITY
by rotating pointer counterclockwise to 10 oclock. This setting normally
ensures good stability, but may not provide optimum response time for
the generator.
If the generator voltage oscillates (hunts), turn the control clockwise past
the point where oscilla tion stops. If faster response is required, rotate
the control counterclockwise until the voltage becomes unstable, and
then rotate clockwise until the voltage is stable. Optimum adjustment
is attained when generator voltage is stable and response is satisfactory
at no-load and also during operation under any load up to the full load
rating of the generator.Parallel voltage droop potentiometer (R4): This adjustment is provided
to control the voltage droop signal of generators operating parallel. It
is located on the regulator chassis. Maximum voltage droop is attained
when the potentiometer is set to its maximum clockwise position. Adjust
each generator that will be operated parallel for identical voltage droop
as described in the parallel operation procedure that follows. Make the
adjustment by loosening the locknut with a 1/2 inch wrench, adjusting
the droop with a screwdriver and then tightening the locknut after the
adjustment has been made.
Underfrequency Adjustment (R55): This adjustment is included in
voltage regulators provided with the underfrequency limit option. R55
is ad justed at the factory as listed above or as requested in the generator
purchase order.
- Adjusting the underfrequency limit when the generator
frequency can be set to the desired breakpoint:
1. Connect a voltmeter between the circuit board
terminals TP1 and TP2.
2. Run generator at the desired underfrequency limit set
point (for example 58 Hz).
3. Adjust R55 for 0 volts as indicated on the meter.
- Adjusting the underfrequency limit when generator
frequency can not be adjusted.
1. Connect a voltmeter between the circuit board
terminals TP1 (negative) and TP2 (positive).
2. Run the generator at rated speed and voltage.
3. Determine the desired underfrequency limit setting voltage
from Table 1 for 60 Hz generators or Table 2 for 50 Hz
generators.
4. Adjust R55 until the voltage between TP1-TP2 equals the test
voltage given in the appropriate table. EXAMPLE: With unit
running at 60 Hz and where limiting is desired at about 55 Hz,
the voltage across TP1-TP2 should be -0.438 Vdc.
