ICS TRIPLEX T3464 PN200158机器人备件
NC R1跳闸触点应与接触器线圈串联。断路器跳闸线圈的监控要求监控电路与R1跳闸继电器输出触点并联。通过这种连接,监控输入电路在触点两端设置阻抗,通过断路器跳闸线圈抽取2 mA电流(对于30至250 V DC的外部电源电压)。监控电路将此涓流电流的损失作为故障条件进行响应。配备标准控制电路的断路器具有断路器辅助触点,仅当断路器闭合时,才允许跳闸线圈通电。当这些触点断开时,如起动器状态数字输入监控断路器辅助触点所检测到的,跳闸线圈监控电路将自动禁用。该逻辑允许仅在断路器闭合时监测跳闸电路。•R2辅助、R3辅助:辅助继电器可编程用于跳闸回声、报警回声、跳闸备用、报警区分、控制电路和许多其他功能。它们应根据配置保证进行接线。•R4报警:报警继电器应连接到适当的报警器或监控装置。•R5阻断启动:该继电器应与断路器或接触器配置中的启动按钮串联,以防止电机启动。当断路器上的跳闸未复位时,闭锁启动继电器会阻止启动尝试,从而导致立即跳闸。任何锁定功能也指向块启动继电器。•R6维修:如果469诊断中的任何一个检测到内部故障或控制电源丢失,维修继电器将工作。该输出可通过报警器、PLC或DCS进行监控。如果认为电机比过程更重要,维修继电器NC触点也可以与断路器应用中的跳闸继电器并联连接,或者NO触点可以与接触器应用中的脱扣继电器串联连接。这将提供电机的故障安全操作;也就是说,如果469没有保护电机,电机将从线路上跳闸。但是,如果过程是关键的,则此类故障的通知将允许操作员或操作计算机继续或顺序停机。详见下图。图2-22:接触器备用接线警告2-18 469电机管理继电器GE Multilin 2.2电气2安装2 2.2.10拉出指示器拉出指示器只是端子E12至F12之间的跳线。当469从外壳中取出时,端子E12和F12断开。这可能有助于区分R6 SERVICE继电器指示的控制功率损失和装置的退出。2.2.11 RS485通信端口提供两个独立的双线RS485端口。多达32 469可以在通信信道上菊花链连接在一起,而不超过驱动器的能力。
applications, the NC R1 Trip contact should be wired in series with the contactor coil. Supervision of a breaker trip coil requires that the supervision circuit be in parallel with the R1 TRIP relay output contacts. With this connection made, the supervision input circuits place an impedance across the contacts that draws a 2 mA current (for an external supply voltage from 30 to 250 V DC) through the breaker trip coil. The supervision circuits respond to a loss of this trickle current as a failure condition. Circuit breakers equipped with standard control circuits have a breaker auxiliary contact permitting the trip coil to be energized only when the breaker is closed. When these contacts are open, as detected by the Starter Status Digital Input monitoring breaker auxiliary contacts, trip coil supervision circuit is automatically disabled. This logic allows the trip circuit to be monitored only when the breaker is closed. • R2 AUXILIARY, R3 AUXILIARY: The auxiliary relays may be programmed for trip echo, alarm echo, trip backup, alarm differentiation, control circuitry, and numerous other functions. They should be wired as configuration warrants. • R4 ALARM: The alarm relay should connect to the appropriate annunciator or monitoring device. • R5 BLOCK START: This relay should be wired in series with the start pushbutton in either a breaker or contactor configuration to prevent motor starting. When a trip has not been reset on a breaker, the block start relay prevents a start attempt that would result in an immediate trip. Any lockout functions are also directed to the block start relay. • R6 SERVICE: The service relay operates if any of the 469 diagnostics detect an internal failure or on loss of control power. This output may be monitored with an annunciator, PLC or DCS. If it is deemed that a motor is more important than a process, the service relay NC contact may also be wired in parallel with the trip relay on a breaker application or the NO contact may be wired in series with the trip relay on a contactor application. This will provide failsafe operation of the motor; that is, the motor will be tripped off line in the event that the 469 is not protecting it. If however, the process is critical, annunciation of such a failure will allow the operator or the operation computer to either continue, or do a sequenced shutdown. See the following figure for details. Figure 2–22: ALTERNATE WIRING FOR CONTACTORS WARNING 2-18 469 Motor Management Relay GE Multilin 2.2 ELECTRICAL 2 INSTALLATION 2 2.2.10 DRAWOUT INDICATOR The Drawout Indicator is simply a jumper from terminals E12 to F12. When the 469 is withdrawn from the case, terminals E12 and F12 are open. This may be useful for differentiating between loss of control power as indicated by the R6 SERVICE relay and withdrawal of the unit. 2.2.11 RS485 COMMUNICATIONS PORTS Two independent two-wire RS485 ports are provided. Up to 32 469s can be daisy-chained together on a communication channel without exceeding the driver capability.
