負(fù)載增益調(diào)整對(duì)于該程序，發(fā)電機(jī)必須同步運(yùn)行，而不是平行。將直流電壓表連接到端子11（–）和13（+）之間進(jìn)行測(cè)量負(fù)載信號(hào)電壓。
啟動(dòng)原動(dòng)機(jī)并施加全負(fù)荷。測(cè)量負(fù)載信號(hào)電壓和將負(fù)載增益電位計(jì)調(diào)整為6.0 V.*如果無法獲得全負(fù)載，與負(fù)載成比例地減小負(fù)載增益。例如，在50%負(fù)載下將負(fù)載增益調(diào)整為3 V。
當(dāng)在同步模式下或在隔離母線上并聯(lián)時(shí)，發(fā)電機(jī)速度必須相同。如果它們不相等，則不會(huì)保持負(fù)載共享與負(fù)載變化成比例。機(jī)組之間的任何負(fù)載差異可能是：通過調(diào)整負(fù)載增益電位計(jì)進(jìn)行校正。增加負(fù)載增益（順時(shí)針轉(zhuǎn)動(dòng)電位計(jì)）將使發(fā)電機(jī)承載更少的負(fù)載。
如果在特定負(fù)載信號(hào)電壓下并聯(lián)時(shí)出現(xiàn)穩(wěn)定性問題，通過降低負(fù)載增益來降低電壓（轉(zhuǎn)動(dòng)電位計(jì)逆時(shí)針），并降低所有其他的負(fù)載信號(hào)電壓設(shè)置系統(tǒng)中的發(fā)電機(jī)電壓相同。當(dāng)負(fù)載信號(hào)電壓系統(tǒng)中的所有發(fā)電機(jī)減少、負(fù)載分配增益減小，并且這可能導(dǎo)致負(fù)載分擔(dān)靈敏度的一些損失。從端子8和9上拆下A相CT導(dǎo)線，然后連接該相連接到產(chǎn)生最高正負(fù)載信號(hào)的一對(duì)端子的導(dǎo)線電壓和產(chǎn)生最高正負(fù)載信號(hào)的極性電壓19.解開并斷開B相CT導(dǎo)線。連接B相CT將導(dǎo)線連接到負(fù)載上剩余兩對(duì)CT輸入端子中的一對(duì)傳感器20.施加全負(fù)荷并測(cè)量負(fù)荷信號(hào)。

Load Gain Adjustment
For this procedure, the generator must be running isochronously and not
paralleled. Connect a dc voltmeter across terminals 11 (–) and 13 (+) to measure
the load-signal voltage.
Start the prime mover and apply full load. Measure the load signal voltage and
adjust the LOAD GAIN potentiometer for 6.0 V. * If full load is not obtainable,
decrease the LOAD GAIN proportionally to the load. For example, at 50% load
adjust the LOAD GAIN to 3 V.
When paralleled in the isochronous mode or on an isolated bus, generator
speeds must be the same. If they are not equal, load sharing will not remain
proportional as the load varies. Any difference in loads between the units can be
corrected by adjusting the Load Gain Potentiometer. Increasing the LOAD GAIN
(turning the potentiometer clockwise) will cause that generator to carry less load.
If stability problems occur when paralleled at a particular load-signal voltage,
reduce the voltage by reducing the LOAD GAIN (turn the potentiometer
counterclockwise), and reduce the load-signal voltage setting of all other
generators in the system to the same voltage. When the load-signal voltages of
all generators in a system are reduced, the load-sharing gain will be reduced,
and this may result in some loss of load-sharing sensitivity. Remove the phase A CT wires from terminal 8 and 9 and connect the phase
A wires to the pair of terminals that produced the highest positive load-signal
voltage and in the polarity that produced the highest positive load-signal
voltage.
19. Untape and disconnect the phase B CT wires. Connect the phase B CT
wires to one pair of the two remaining pair of CT input terminals on the load
sensor.
20. Apply full load and measure the load signal. Start a new list and record this
voltage.
21. Unload the system, and reverse the phase B CT wires on the same
terminals. *
22. Apply full load, measure the load signal, and record this voltage.
23. Unload the system, remove the phase B CT wires, and connect them to the
other pair of terminals. *
24. Apply full load, measure the load signal, and record this voltage.
25. Unload the system and reverse the phase B CT wires on the same
terminals. *
26. Apply full load and measure the load signal. Record this voltage, and
compare the four voltages on the list.
27. Unload the system. Remove the phase B CT wires and connect them to the
pair of CT input terminals that produced the highest positive load signal
voltage and with the polarity that produced the highest positive load signal
voltage. Untape and disconnect the phase C CT wires. Connect these two wires to
the remaining pair of CT input terminals.
29. Apply full load, measure the load signal, and record this voltage.
30. Unload the system and reverse the phase C CT wires on the same
terminals. *
31. Apply full load, measure the load signal, and record this voltage.
32. Unload and shut down the system. Compare the two voltages. *
33. Connect the phase C CT wires to the same pair of CT input terminals, but in
the polarity that produced the highest positive load-signal voltage.
34. Re-label each wire with the phase designation of the terminal that it is now
connected to.
35. Remove the burden resistors and terminal block.
*—Be sure to shut down the prime mover if the temporary burden resistors
are not used.
