发电机单独运行：当发电机不并联运行时如果不需要无功电压降，则使用以下方法之一消除并联变压器影响的方法在电压调节器内。
-在电流互感器上安装一个单元/并联开关在单台发电机运行期间关闭开关。
-将电压下降电阻器R4设置为其小下降位置。
-在发电机单独运行的情况下，安装跨接线端子CT和CT1。
UFL电路50/60和400 Hz选择器J1：低频限值部件或V/Hz部件位于电压调节器上
电路板（见图9）。组成UFL或V/Hz的部件部件如图11所示。跨接导线J1消除了
电阻器R57的影响。拆下跨接线J1将R57置于电路中。
60或400 Hz操作：确保跨接导线安装在标记为J1的区域。导线安装在电路板的组件侧，并且
跨接导线的端部焊接在电路板的箔侧。
50Hz操作：确保跨接导线已从跨接导线上拆下标记J1的区域。通过切断跨接导线的两端拆下J1。
电压调节器保险丝：电压调节器包含15 a正常值熔断电压调节器输入电源电路中的保险丝（见图1、2和3）。在电压调节器功率要求为：减少，如与小型发电机一起使用时，励磁小于因此，可以使用较小的保险丝。切勿安装大于15 a的保险丝切勿安装延迟型保险丝。
附件项目：发电机系统提供的附件项目
必须按照随附的接线图所示进行连接发电机组和附件项目图纸或说明。看到连接时应遵循的注意事项和一般程序配件。
电压停机（发动机怠速开关）：系统可配备在紧急情况下或当原动机必须以降低的速度运行。此开关必须为放置在调节器的输入电源线上（端子P1或P2）。现场断路器 eld断路器必须为以下类型：具有用于热元件和触点的单独端子。

and reactive voltage droop is not required, use one of the following
methods to eliminate the effect of the parallel operation transformer
within the voltage regulator.
- Install a unit/parallel switch across the current transformer
secondary, and close switch during single generator operation.
- Set the voltage droop resistor R4 to its minimum droop position.
- Where the generator will be operating singly, install a jumper across
terminals CT and CT1.
UFL circuit 50/60 and 400 Hz selector J1: The underfrequency limit
components or V/Hz components are located on the voltage regulator
circuit board (see Figure 9). Parts comprising the UFL or V/Hz
components are shown in Figure 11. A jumper wire J1 eliminates the
effect of resistor R57. Removing the jumper J1 places R57 in the circuit.
60 or 400 Hz operation: Make certain the jumper wire is installed across
area marked J1. Wire is mounted on component side of circuit board and
ends of jumper wire are soldered on foil side of the circuit board.
50 Hz operation: Make certain the jumper wire is removed from across
area marked J1. Remove J1 by cutting each end of the jumper wire.
Voltage regulator fuse: The voltage regulator contains a 15 A normal
blow fuse in the voltage regulator input power circuit (see Fig. 1, 2
and 3). In applications where voltage regulator power requirements are
reduced, as when used with small generators where excitation is less than
given, a smaller fuse may be used. Never install a fuse larger than 15 A
and never install a delay-type fuse.
Accessory items: Accessory items provided with the generator system
must be connected as shown on the wiring diagram provided with the
generator set and the accessory item drawing or instruction. Observe
the precautions and general procedures that follow when connecting
accessory items.
Voltage shutdown (engine idle switch): The system can be equipped with
a switch to allow removal of excitation in an emergency or when the
prime mover must be operated at reduced speeds. This switch must be
placed in the input power line to the regulator (terminal P1 or P2).
Field circuit breaker: The  eld circuit breaker must be of the type that
has separate terminals for the thermal element and the contacts.
The circuit breaker thermal element receives heat from either the  eld
current or generator line current. Where it is heated by  eld current, the
thermal element connects between the voltage regulator output and the exciter  eld. Where it is heated by generator line current, the thermal
element connects to a current transformer located in one of the generator
load lines.
Auto/manual voltage control: The auto/manual voltage control option
includes the components described below. Connect the auto/manual
voltage control module as shown on the wiring diagram provided with
the generator.
- Three-position selector switch: When this switch is set to the AUTO,
power is fed across the switch contacts to the regulator input power
terminal P1 and P2. When the switch is set to MAN, power is fed
across the switch contacts to the manual voltage control circuit
recti ers. OFF position opens input power to both the voltage
regulator and the manual voltage control recti ers.
- Manual voltage control circuit: The manual voltage control circuit
consists of a full wave recti er assembly and a manual voltage
control variac. The manual voltage control variac controls generator
output whenever the generator set is operated in the manual voltage
control mode of operation.
