（过载曲线），如果电机启动扭矩持续存在于卡住或损坏的设备上，也可以防止或限制对被驱动设备的损坏。在正常运行期间，机械堵塞拾取水平应设置为高于电机负载，但低于电机失速水平。通常，将延迟设置为最小时间延迟，或设置为不会因瞬时负载波动而产生干扰跳闸。❙ 过载报警器❙ [ENTER]更多过载报警：关闭范围：关闭、锁定、未锁定分配报警继电器：报警范围：报警、辅助2、辅助3、报警和辅助2、报警和辅3、辅助2和辅助3、警报和辅助2和辅3过载报警延迟：0.1 s范围：0.1至60秒，步骤：0.1过载报警事件：关闭范围❙ 机械堵塞❙ [输入]更多机械堵塞跳闸：关闭范围：关闭、锁定、未锁定分配跳闸继电器：跳闸范围：跳闸、跳闸和辅助2、跳闸和辅2和辅助3；跳闸和辅助3机械堵塞传感器：1.50 x FLA范围：1.01至3.00 x FLA，步骤0.01机械堵塞延迟：1秒范围：1至30秒。，步骤1输入退出信息退出信息退出消息退出消息退出重置退出退出信息退出4-48 469电机管理继电器GE电源管理4.7 S6电流元件4设定值编程4 4.7.4欠电流a）功能一旦达到Ia、Ib、Iba、Ib和Ib值，或Ic在欠电流报警延迟指定的时间内低于拾取电平×FLA。欠电流元件仅在电机运行时激活。在电机启动启动时，在U/C BLOCK FROM start（U/C阻止启动）设定点规定的时间内将其阻断（例如，该阻断可用于允许泵在欠流元件跳闸之前建立扬程）。值“0”表示该功能从开始时未被阻止。如果输入的值不是“0”，则当电机停止时，以及从检测到启动到输入的时间结束时，该功能将被禁用。在正常操作期间，欠电流报警拾取水平应设置为低于电机负载。b） 示例：如果泵被泵送的液体冷却，负载损失可能意味着泵过热。在这种情况下，启用欠流功能。如果电机负载永远不会低于0.75×FLA，即使在短时间内，欠电流跳闸传感器也可以设置为“0.70”，欠电流报警传感器设置为“0.75”。如果泵始终启动负载，则应禁用“从启动开始阻止欠电流”设定点（编程为0）欠电流报警延迟/欠电流跳闸延迟通常设置得尽可能快，即1秒。❙ 潜流，潜流❙ [ENTER]欲了解更多来自启动的阻止欠电流：0 s范围：0到15000秒，步骤：1欠电流报警：关闭范围：关闭、锁定、未锁定分配报警继电器：报警范围：报警、报警和辅助2、报警和辅2和辅3、辅2和辅助3、辅3欠电流报警拾取：0.70 x FLA范围：0.10到0.95 x FLA，步骤：0.01欠电流报警延迟：1 s范围：1到60秒。，步骤：1欠电流报警事件：关闭范围：打开，关闭欠电流跳闸：关闭范围，关闭，锁定，未锁定分配跳闸继电器：跳闸范围：跳闸，跳闸和辅助2，跳闸和辅2和辅3，跳闸和附属3欠电流跳闸传感器：0.70 x FLA范围：0.10至0.99 x FLA
(overload curve), it may also prevent or limit damage to the driven equipment if motor starting torque persists on jammed or broken equipment. The MECHANICAL JAM PICKUP level should be set higher than motor loading during normal operation, but lower than the motor stall level. Normally the delay is set to the minimum time delay or set so that no nuisance trips occur due to momentary load fluctuations. ❙ OVERLOAD ALARM ❙ [ENTER] for more OVERLOAD ALARM: Off Range: Off, Latched, Unlatched ASSIGN ALARM RELAYS: Alarm Range: Alarm, Auxiliary2, Auxiliary3, Alarm & Aux2, Alarm & Aux3, Aux2 & Aux3, Alarm & Aux2 & Aux3 OVERLOAD ALARM DELAY: 0.1 s Range: 0.1 to 60 sec., step: 0.1 OVERLOAD ALARM EVENTS: Off Range: On, Off ❙ MECHANICAL JAM ❙ [ENTER] for more MECHANICAL JAM TRIP: Off Range: Off, Latched, Unlatched ASSIGN TRIP RELAYS: Trip Range: Trip, Trip & Auxiliary2, Trip & Aux2 & Aux3; Trip & Auxiliary3 MECHANICAL JAM PICKUP: 1.50 x FLA Range: 1.01 to 3.00 x FLA, step 0.01 MECHANICAL JAM DELAY: 1 s Range: 1 to 30 sec., step 1 ENTER ESCAPE ð ð MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE RESET ENTER ESCAPE ð ð MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE 4-48 469 Motor Management Relay GE Power Management 4.7 S6 CURRENT ELEMENTS 4 SETPOINT PROGRAMMING 4 4.7.4 UNDERCURRENT a) FUNCTION A trip or alarm will occurs once the magnitude Ia, Ib, or Ic falls below the pickup level × FLA for the time specified by the UNDERCURRENT ALARM DELAY. The Undercurrent element is active only when the motor is running. It is blocked upon the initiation of a motor start for the time defined by the U/C BLOCK FROM START setpoint (e.g. this block may be used to allow pumps to build up head before the undercurrent element trips). A value of "0" means the feature is not blocked from start. If a value other than "0" is entered, the feature is disabled when the motor is stopped and also from the time a start is detected until the time entered expires. The UNDERCURRENT ALARM PICKUP level should be set lower than motor loading during normal operations. b) EXAMPLE If a pump is cooled by the liquid it pumps, loss of load may mean that the pump overheats. In this case, enable the undercurrent feature. If the motor loading should never fall below 0.75 × FLA, even for short durations, the UNDERCURRENT TRIP PICKUP could be set to "0.70" and the UNDERCURRENT ALARM PICKUP to "0.75". If the pump is always started loaded, the BLOCK UNDERCURRENT FROM START setpoint should be disabled (programmed as 0). • the UNDERCURRENT ALARM DELAY / UNDERCURRENT TRIP DELAY is typically set as quick as possible, i.e. 1 s. ❙ UNDERCURRENT ❙ [ENTER] for more BLOCK UNDERCURRENT FROM START: 0 s Range: 0 to 15000 sec., step: 1 UNDERCURRENT ALARM: Off Range: Off, Latched, Unlatched ASSIGN ALARM RELAYS: Alarm Range: Alarm, Alarm & Auxiliary2, Alarm & Aux2 & Aux3, Auxiliary2, Aux2 & Aux3, Auxiliary3 UNDERCURRENT ALARM PICKUP: 0.70 x FLA Range: 0.10 to 0.95 x FLA, step: 0.01 UNDERCURRENT ALARM DELAY: 1 s Range: 1 to 60 sec., step: 1 UNDERCURRENT ALARM EVENTS: Off Range: On, Off UNDERCURRENT TRIP: Off Range: Off, Latched, Unlatched ASSIGN TRIP RELAYS: Trip Range: Trip, Trip & Auxiliary2, Trip & Aux2 & Aux3, Trip & Auxiliary3 UNDERCURRENT TRIP PICKUP: 0.70 x FLA Range: 0.10 to 0.99 x FLA
