    • A load abnormality detecting system and method for detecting the burnout and short circuit of a load are provided. A voltage generator (10) generates a specified voltage Vs in accordance with a load current IL. A judging device (4) compares a signal corresponding to this voltage (Vs) with a specified reference value (T1, T2) to judge whether a load (2) has any abnormality. A selector (6) causes the burnout reference value (T1) to be inputted to the judging device (4) and controls the voltage generator (10) to use a first resistance value when checking the burnout of the load (2) while causing the short-circuit reference value (T2) to be inputted to the judging device (4) and controlling the voltage generator (10) to use a second resistance value when checking the short circuit of the load (2).
    • 提供一种用于检测负载的烧坏和短路的负载异常检测系统和方法。 电压发生器(10)根据负载电流IL产生规定的电压Vs。 判断装置(4)将与该电压(Vs)对应的信号与规定的基准值(T 1,T 2)进行比较,判断负载(2)是否有异常。 选择器(6)使得烧断参考值(T 1)被输入到判断装置(4),并且当检查负载(2)的烧坏时,控制电压发生器(10)使用第一电阻值,同时引起 输入到判断装置(4)的短路参考值(T 2),并且在检查负载(2)的短路时控制电压发生器(10)使用第二电阻值。
