端子52L和52M處的用戶提供的觸點(diǎn)確定AVR或下垂模式是否激活。
端子52L和52M通常連接到發(fā)電機(jī)斷路器的52b輔助觸點(diǎn)。端子52J和52K處的用戶提供觸點(diǎn)控制var或功率因數(shù)校正是否激活殘廢端子52J和52K通常連接到公用設(shè)施連接斷路器的輔助觸點(diǎn)。桌子4-3列出了不同52L/M和52J/K接觸狀態(tài)下實(shí)現(xiàn)的操作模式。
封閉狀態(tài)指示連續(xù)觸點(diǎn)閉合
而開路狀態(tài)指示連續(xù)開路。電壓匹配（可選）此功能的客戶提供的啟用/禁用觸點(diǎn)連接到標(biāo)有VM和的端子VMC。只有干燥、不接地的開關(guān)觸點(diǎn)應(yīng)用于電壓匹配觸點(diǎn)輸入。
電壓匹配也通過(guò)52J/K和/或52L/M觸點(diǎn)輸入的狀態(tài)啟用/禁用。在里面當(dāng)52J/K或52L/M觸點(diǎn)輸入為打開或僅52J/K觸點(diǎn)輸入打開。電源輸入

DECS-100可以直接從各種電源供電，只要DECS-100INPUT電源規(guī)范（見第1節(jié)，一般信息，規(guī)范）。
DECS-100操作電源的示例包括：?發(fā)電機(jī)（并聯(lián)供電）
永磁發(fā)電機(jī)（PMG）
?輔助繞組
當(dāng)從低阻抗電源向DECS-100供電時(shí)，必須作出特殊規(guī)定：避免損壞DECS-100。低阻抗電源的示例包括電站服務(wù)電源或電源插座。浪涌電流降低模塊ICRM-7必須連接在電源和DECS-100輸入電源端子（見圖4-10）。ICRM-7防止DECS-100通過(guò)最大限度地降低浪涌電流水平造成的損壞。ICRM-7也可用于編程DECS-100。但是，初步設(shè)置段落說(shuō)明了臨時(shí)為DECS-100提供編程電源。有關(guān)ICRM-7的更多詳細(xì)信息，請(qǐng)參見Basler Electric出版物9387900990。
Voltage Matching (Optional) A customer-supplied enable/disable contact for this function connects to the terminals labeled VM and VMC. Only dry, ungrounded switching contacts should be applied to the Voltage Matching contact input. Voltage matching is also enabled/disabled by the state of the 52J/K and/or 52L/M contact inputs. In BESTCOMS, voltage matching can be configured to be disabled when the 52J/K or 52L/M contact input is open or just the 52J/K contact input is open. Power Supply Inputs Power input terminals are labeled 3, 4, and 5. Single-phase or three-phase power may be applied. Singlephase power may be applied to any two of the three terminals. The DECS-100 can be powered directly from a variety of sources as long as the DECS-100 input power specifications are followed (see Section 1, General Information, Specifications). Examples of DECS-100 operating power sources are: ? Generator (shunt fed) ? Permanent magnet generator (PMG) ? Auxiliary winding When powering the DECS-100 from a low-impedance power source, special provisions must be made to avoid damage to the DECS-100. Examples of a low-impedance power source include a station service source or power outlet. An Inrush Current Reduction Module, ICRM-7, must be connected between the power source and DECS-100 input power terminals (see Figure 4-10). The ICRM-7 prevents DECS-100 damage by minimizing the level of inrush current. The ICRM-7 can also be used when programming the DECS-100. However, the Preliminary Setup paragraphs illustrate an alternate method for temporarily powering the DECS-100 for programming. More details about the ICRM-7 are available in Basler Electric publication 9387900990.
