Hawkeye 934 microprocessor-based current status switches provide a unique solution for accurately monitoring status of motors controlled by variable frequency drives. The H934 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. APPLICATIONS   Monitoring positive status on motors controlled by variable frequency drives Replacing pressure switches Microprocessor-based ... real labor saver. No need to calibrate to detect belt loss on VFDs   Self-adjusting trip point; factory programmed to detect belt loss undercurrent conditions Provides accurate status for VFD loads Automatically compensates for the effects of frequency and amperage changes associated with VFDs LED indicates normal and alarm conditions Huge labor savings - no need to calibrate in live starter enclosures; install and go Available with a relay; status and control in one package, saving time and space Bracket can be installed in three different configurations; added flexibility Accurately detects belt loss and coupling shear on VFD driven motors   Monitors both frequency and amperage; distinguishes normal drops in amperage due to frequency changes from abnormal drops due to mechanical failure Split-core design is ideal for retrofits; no need to remove conductor 5-year limited warranty
