Hawkeye 904 microprocessor-based current status switches provide a unique solution for accurately monitoring status of motors controlled by variable frequency drives. The H904 stores the sensed amperage values for normal operation at various frequency ranges in non-volatile memory. This information allows the device to distinguish between a reduced amp draw due to normal changes in the frequency and an abnormal amp drop due to belt loss or other mechanical failures.
