Watchdog "Elite" Bucket Elevator Monitor
The bucket elevator monitor for the 21st century. The 4B Watchdog
"Elite" uses non-contacting, magnetic sensors to monitor belt speed
and belt alignment at the head / boot or both. Additional sensors

The system incorporates dual microprocessor control, using the latest
PIC microprocessors and non-volatile (EEPROM) memory chips. An
LCD screen displays elevator status messages (available in four

All units automatically select supply voltages from 110VAC to 240VAC
(50-60 HZ) and supply the sensors with fully regulated 12VDC.
Voltage free isolated relay contacts are provided for alarm, stop,
underspeed, misalignment, and temperature. RS485 communication
is also available for connection to plant computers / PLCs. Simple
menu-driven calibration and parameter adjustment. Cert: ATEX/IEC
