Zhengzhou Winsen Electronics Technology Co., Ltd. www.winsen-sensor.com Safety Zone Danger Zone Safety Barrier Sensor The distribution parameters of the connecting cable between the safety barrier and the sensor should meet: Cc≤Co-Ci Lc≤Lo-Li Ui≥Uo Ii≥Io Pi≥Po
Note:
Uo: Maximum output voltage of safety barrier; Io: Maximum output current of safety barrier Po: Maximum output power of safety barrier Co: Maximum external capacitance of safety barrier Lo: the maximum external inductance of the safety barrier (see the safety barrier instructions for the above parameters book) Cc: Maximum allowable distributed capacitance of connecting cable Ui: sensor maximum input voltage Ii: Maximum sensor input current Pi: sensor maximum input power Ci: Maximum internal capacitance of the sensor Li: Maximum internal inductance of the sensor Lc: Maximum allowable distributed inductance of connecting cable
7. Cautions for Maintenance
7.1 The sensor should be calibrated regularly. The suggested cycle time is 6 months. 7.2 Do not use the sensor in the high dusty environment for long time. 7.3 The sensor should be kept away from heat sources and away from direct sunlight or other thermal radiation. 7.4 Please use the sensor with correct power supply. 7.5 Forbid to weld the sensor pins directly. 7.6 Forbid to cut the sensor pins.
