IS200HFPRG1A处理器模块
因失去励磁和具有电压限制功能的TOC而跳闸，因为它们可能会在失去交流电的情况下继续运行。意外通电DGP系统使用内部逻辑来检测发电机的意外通电。可配置I/O两个通用触点转换器输入允许轻松连接外部跳闸或报警触点，允许使用事件日志和DGP的可配置输出。可选输入可配置为禁用所有保护功能。八个可配置输出继电器，四个跳闸和四个报警，允许用户选择任何所需的功能组合。输出继电器可以通过安全授权或硬接线跳线远程或本地控制。DGP的控制功能可以本地或远程操作输出继电器。可配置逻辑DGP允许对内部逻辑进行战略性修改，以支持安全性或可靠性。这可以通过软件设置或通过“发电机离线”触点输入自动完成。该功能允许在发电机离线时禁用所选功能，并修改意外通电逻辑。触点扩展单元DEC 1000单元是一个智能触点扩展单元，它提供额外的11个输出继电器，5个触点为“C”配置，6个触点为常开触点。11个LED指示触点的操作，一个重置按钮测试并重置单元。适用于“CA”仅限型号。DEC 1000扩展了DGP控制的输出数量。监控和计量DGP具有高级计量和事件记录功能，包括：自检和诊断自检例行程序在通电期间执行，并在服务期间继续在后台运行。故障分为严重或非严重报警在严重报警期间，保护功能自动禁用，有助于保持DGP的高度安全性。DGP还具有一个继电器测试菜单，通过允许测试保护系统的单个保护功能和输出继电器，可方便安装。跳闸电路监测器此功能由跳闸电压监测器（TVM）和跳闸电流监测器（TCM）组成，最多可用于四个跳闸输出触点。TVM检测到外部跳闸电路中的任何中断，并产生非关键报警。当DGP发出跳闸时，TCM确认跳闸电路通电。为了保护输出触点，只要跳闸电流流动，TCM可用于密封跳闸输出。计量DGP提供以下计量值：电流（Ia、Ib、Ic）电压
tripping by the loss of excitation and TOC with voltage restraint functions, as they may continue operating with a loss of AC. Accidental Energization The DGP system uses internal logic to detect accidental energization of the generator. Configurable I/Os Two general purpose contact converter inputs allow easy connection of external trip or alarm contacts, permitting use of the event log and configurable outputs of the DGP. An optional input can be configured to disable all protections functions. Eight configurable output relays, four trip and four alarm, allow the user to select any desired combination of the functions. Output relays can be controlled remotely or locally through a secured authorization or hardwire jumper. The control functions of the DGP can operate output relays locally or remotely. Configurable Logic The DGP allows strategic modification of internal logic to favor either security or dependability. This can be accomplished either by software settings or automatically by a "Generator Offline" contact input. This feature allows disabling of selected functions when the generator is offline and modification of the Accidental Energization logic. Contact Expansion Unit The DEC 1000 unit is an intelligent contact expansion unit that provides an additional 11 output relays, five with contacts in ‘C’ configuration, and six with normally open contacts. Eleven LEDs indicate operation of contacts, and a reset button tests and resets the unit. Available for “CA“ model only. The DEC 1000 expands the number of outputs controlled by the DGP. Monitoring and Metering The DGP features advanced metering and event recording functions which include: Self-Tests and Diagnostics Self-test routines are performed during power-up and continue to run in the background during service. Failures are categorized as either a critical or non-critical alarm. Appropriate protective functions are automatically disabled during a critical alarm, helping to maintain the high security of the DGP. The DGP also has a RELAY TEST menu which facilitates installation by allowing testing of individual protective functions and output relays for the protection system. Trip Circuit Monitor This function consists of the Trip Voltage Monitor (TVM) and the Trip Current Monitor (TCM) for up to four trip output contacts. The TVM detects any discontinuity in the external trip circuit and produces a non-critical alarm. The TCM confirms energizing of the trip circuit when a trip is issued by the DGP. To protect the output contacts the TCM may be used to seal-in the trip output as long as trip current is flowing. Metering The DGP provides the following metering values: Currents (Ia, Ib, Ic) Voltages
