启动原动机/发电机，并在额定速度和负载下进行最终调整。
初始启动后，DECS-100不需要任何进一步调整，除非系统的变化。
由于其脉宽调制（PWM）功率级，DECS-100工作功率输入具有大量电容。DECS-100通电时会出现高浪涌电流当使用“固态”电源时。为DECS-100通电以进行电压编程时大于120 Vac时，高涌入电流可能会损坏装置。因此，在编程期间，DECS100工作功率应在30至120 Vac（50/60 Hz）范围内。
DECS-100编程期间的操作功率考虑
如果有必要在120 Vac以上的工作电源下执行编程，电流限制
电阻器必须连接在电源和DECS-100之间（图4-12）。额定值为20欧姆和20瓦可用于将浪涌电流限制在安全水平。在浪涌电流（大约一个周期），将超过电阻器的额定功率。一旦涌入已经过去，电阻器功耗水平将是最小的。如果需要，可以使用10欧姆、50瓦的电阻器相反只有在DECS-100编程过程中才能观察到这些特殊操作注意事项。DECS-100由发电机输出（并联供电）或永久电源供电的应用磁体发生器（PMG）在第1节“一般信息”中给出的约束范围内仍然有效，规格。在使用电站电源为DECS-100供电的应用中应通过浪涌电流降低模块（ICRM-7）进行保护。有关更多信息，请参阅电源输入信息调整
所有调整均使用外部开关或通过后面板使用BESTCOMS软件进行通信端口。有关设置调整的更多信息，请参阅第5节和第6节BESTCOMS软件。BESTCOMS-DECS100软件提供DECS-100和用户之间的通信链路。所有DECS-100设置均通过BESTCOMS输入，所有计量值（更新约一次每隔一秒）通过BestCom读取。BESTCOMS中的软件允许用户建立基于指定发电机和/或励磁机的适当PID（比例+积分+微分）参数时间常数。在BESTCOMS中，DECS-100设置可以保存在计算机文件中，并在以后用于使用相同设置配置其他装置。
Connect only the DECS-100 power input terminals to an auxiliary power source. Before applying
DECS-100 operating power, observe the precautions noted in Operating Power Considerations
During DECS-100 Programming.
5. Perform all initial DECS-100 settings by connecting a PC operating with BESTCOMS to the rear
communication port of the DECS-100 and save all new settings.
6. Remove power from the DECS-100.
7. Connect the rest of the DECS-100 leads using the tagged identification.
8. Start the prime mover/generator and perform the final adjustments at rated speed and load.
9. After the initial startup, the DECS-100 should not require any further adjustments unless there is a
change in the system.
Operating Power Considerations During DECS-100 Programming
Due to its pulse-width modulated (PWM) power stage, the DECS-100 operating power input has a
substantial amount of capacitance. High inrush current can be experienced upon DECS-100 power-up
when a "solid" power source is used. When powering the DECS-100 for programming with voltage
greater than 120 Vac, high inrush current may damage the unit. Therefore, during programming, DECS100 operating power should be within the range of 30 to 120 Vac (50/60 Hz).
If it is necessary to perform programming with applied operating power over 120 Vac, a current-limiting
resistor must be connected between the power source and DECS-100 (Figure 4-12). A resistor rated at
20 ohms and 20 watts may be used to limit the inrush current to a safe level. During the duration of the
inrush current (about one cycle), the resistor power rating will be exceeded. Once the inrush has passed,
the resistor power dissipation level will be minimal. If desired, a 10 ohm, 50 watt resistor may be used
instead. These special operating considerations are to be observed only during DECS-100 programming.
Applications where the DECS-100 is powered from the generator output (shunt powered) or a permanent
magnet generator (PMG) are still valid within the constraints given in Section 1, General Information,
Specifications. In applications where station power is used to power the DECS-100, the DECS-100
should be protected by an Inrush Current Reduction Module (ICRM-7). See Power Supply Inputs for more
information.
ADJUSTMENTS
All adjustments are made using external switching, or with BESTCOMS software via the rear panel
communication port. See Sections 5 and 6 for more information regarding setting adjustments with
BESTCOMS software. BESTCOMS-DECS100 software provides the communication link between the DECS-100 and the user.
All DECS-100 settings are entered through BESTCOMS and all metering values (updated about once
every second) are read through BESTCOMS. Software within BESTCOMS enables the user to establish
proper PID (proportional + integral + derivative) parameters based on a specified generator and/or exciter
time constants. Within BESTCOMS, DECS-100 settings can be saved in a computer file and used later to
configure other units with the same settings.
