    ZCT215L2-SQS-A1G-4007 is a new generation cost-effective dual axis tilt switch researched and developed by ZC Technology. This product is based on the 32-bit high-performance microprocessor, which is calibrated to the zero deviation and sensitivity deviation of the sensor to ensure the reliability and consistency. The sensor comes with its own blister, by looking at the water bubble position and setting the zero button, so as to meet the requirements of the site and be convenient to the user.



    Built-in 32-bit microprocessor, faster operation speed.

    Non-contact sensitive components, longer life.

    Remark 1: Resolution is the minimum amount of change that the sensor can detect in the measurement range.

    Remark 2: Accuracy is the difference between the output value of the sensor and the true corresponding input value.

    1) Status indication

    When the product powered on first time, the indicator light flashes red and green twice alternatively, then green or red light normally on. (Green light on indicates the tilt angle is under non-alarm state, electrical switch on; when red light on indicates the tilt angle is under alarm state, electrical switch off.)

    After tilt angle is continuously larger than the preset alarm angle for 1.5s (alarm delay 1.5s), the inside electrical switch off, alarm signal cable output is high-impedance state. After green light flashes, the green light off, red light on.

    Once the tilt angle is smaller than the preset alarm angle (Recovery delay 0s), inside electrical switch on, alarm signal cable output is close to supply voltage. ( Due to overload protection device inside, the output voltage is always slightly smaller than supply voltage) Now the green light is stays on, red light stays off.

    2) Zero point

    Cooperate with blister status, user can set relative zero point by zero button. After press zero button, indicator light flashes between red and green alternatively, last 4 second, the indicator light turns to orange, which means zero set success. Release the button, the green light stays on, red light stays off.
