1. Contact Sensor PCS-250 with Needle Assembly
Teaching the sensor a tool is as single as pressing the teach button on the control unit. Once the entire swing cycle has been learned, any low tolerance deviation from those parameters will be interpreted as a fault condition.
打开控制器的教学按钮即可启动检测器教学模式，一旦整个摆动周期被设定，这些参数中的任何低偏差将被认定为故障状态。
Memorized swing movement is stored in memory and does not reguire another teaching cycle when power has been removed.
摇摆运动的记忆自动存储在内存卡里，即使切断电源也不需要重新设定教学周期。
Swing angle of needle is memorized, either CW or CCW direction, up to 300°max. CW or CCW can be changed by the switch on the control unit.
当探针摆动角度被记忆，不管是正转方向还是反转方向，哪怕角度达到300°都可以通过控制器更改方向。
Contact Pressure of needle (speed of needle swing) can be changed in 3 steps by the switch of control unit. The lowest swing speed is ideal for the small dia. of tools. Up to about 0.4mm dia. of tools can be detected.
只需要三步即可在控制器上调整探针的接触压力（探针旋转速度），旋转速度适合测小尺寸的被测工具，测量工具尺寸为0.4mm。
Swing speed of the needle can be selected in several steps. It can help to minimize the cycle time of machining,
探针旋转速度只需要遵循几个步骤操作即可进行选择，这样能有效地缩短机器加工周期

OK output
If a tool is detected, OK relay outputs a momentary or latch signal. Green LED illuminates.
FAULT output
When a broken tool condition is detected, FAULT relay outputs a momentary or latch signal Red LED illuminates.
当检测到破损件时，瞬间发出一个故障信号，红色LED灯亮起
