4B Watchdog "Elite"運用非接觸，磁性傳感器監控帶速和頭部/尾部或兩者傳送帶調整，附加的傳感器監控軸承溫度，主動皮帶輪調整＆插入噴管的狀況。 該系統結合了雙微處理器控制，采用最新的PIC微處理器＆非易失性（EEPROM）存儲片。 LCD液晶顯示升降機狀態信息（四種語言可用），超亮LED顯示傳動帶速度。 所有部件自動選擇電壓范圍110VAC 到240VAC （50-60 HZ），傳感器電壓12VDC。電壓自由隔離繼電器觸點用于報警，停止，減速，位移＆溫度調整。 RS485通訊同樣用于連接到工廠電腦/PLC,簡單菜單指示校準＆參數調整。 original text： [COLOR=#708090]Watchdog “Elite”Bucket Elevator monitors The 4B Watchdog "Elite" uses non-contacting, magnetic sensors to monitor belt speed and belt alignment at the head / boot or both. Additional sensors monitor bearing temperature, head pulley alignment and plugged spout conditions. 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 different languages） and a super-bright LED screen displays belt speed. 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. [/COLOR]
