产品详情资料
RTD短路/低温469具有RTD短路/低温度报警。该警报将查看所有已编程报警或跳闸的RTD,并确定RTD是否存在短路或温度过低(低于–50°C)。任何没有跳闸或报警的RTD都将被忽略。当检测到短路/低温时,指定的输出继电器将工作,显示屏上将显示一条信息,识别导致报警的RTD。建议使用此功能时,将报警编程为锁存状态,以便检测到间歇性RTD和元件4 4.10 S9电压元件4.10.1欠压。只有在总线通电时,U/V激活设置点可用于防止总线未通电时的有害报警或跳闸。如果该设定点编程为“是”,则任何报警/跳闸至少有一个电压必须大于额定铭牌电压额定值的20%。如果负载具有高惯性,则可能需要使电机离线跳闸或在线路电压完全损失的情况下防止电机启动。 RTD SHORT/LOW TEMP The 469 has an RTD Short/Low Temperature alarm. This alarm will look at all RTDs that have either an alarm or trip programmed and determine if an RTD has either a short or a very low temperature (less than –50°C). Any RTDs that do not have a trip or alarm associated with them will be ignored for this feature. When a short/ low temperature is detected, the assigned output relay will operate and a message will appear on the display identifying the RTD that caused the alarm. It is recommended that if this feature is used, the alarm be programmed as latched so that intermittent RTDs are detected and ELEMENTS 4 4.10 S9 VOLTAGE ELEMENTS 4.10.1 UNDERVOLTAGE The U/V ACTIVE ONLY IF BUS ENERGIZED setpoint may be used to prevent nuisance alarms or trips when the bus is not energized. If this setpoint is programmed to "Yes", at least one voltage must be greater than 20% of the nominal nameplate voltage rating for any alarm/trip. If the load is high inertia, it may be desirable to trip the motor off-line or prevent it from starting in the event of a total loss of line voltage.
