3.設置
先按(an)BET鍵出現數碼閃爍(shuo),再按(an)■■鍵到顯示:1、2、3。再按BET鍵出現數碼(ma)閃爍，再按■鍵調整打(da)滑轉數值，再按BET鍵(jian)設置成功。

4.使用與安裝

5.主要技術參數

The underspeed slip switch is a highly reliable, simple and versatile monitoring device for shaft speed and other rotating devices.When it is detected that the current speed signal is lower than the normal speed range, the switch outputs a switch signal foralarm or shutdown.No moving parts, no wear, long safety life, integrated structure , centralized control device, simple setting ortroubleshooting.

2.Working Principle
The underspeed slip switch is used to detect the rotation speed of the tail wheel of the beltconveyor, and the switch has nocontact with the tail shaft.When the tail shaft rotates with the running of the belt conveyor, the induction piece is driven, and theinduction signals generated by the induction piece and the detector are input into the control circuit.Ater enlarging and reshaping.the count is compared with the preset number to judge the speed of the tape.That is, when the speed is lower than the slip speed,the execution circuit outputs the corresponding switch signal to stop the host.This switch can adjust the speed value.Theunderspeed slip switch is used to detect the rotation speed of the tail wheelof the beltconveyor, and the switch has no contact withthe tailshaft.When the tail shaft rotates with the running of the belt conveyor, the induction piece is driven,and the inductionsignals generated by the induction piece and the detector are input into the control circuit.Ater enlarging and reshaping, thecount is compared with the preset number to judge the speed of the tape.That is, when the speed is lower than the slip speed,the execution circuit outputs the corresponding switch signal to stop the host.This switch can adjust the speed value.

3.Options

First press the BET key to display the number flashing, then
press the .keys to display : 1,2,3.
Press the BET key again to make the number flash, and then
press the  key to adjust the slip rotation value.Press the
BET key again to set successfully.

4.Use & lnstallation
The underspeed skid switch is installed on the side of the driven wheel or other shaft of the conveyor which can be equal to theactual speed of the beltThe size of the Induction Cross section is not less than 50mmX 50mm, and the maximum distance betweenthe underspeed sliding switch and the induction surface is 25mm.The sensing surface provides a pulse signal for the under-speedslip switch, and the driven wheel rotates once through an under-speed slip switch area to generate a pulse signal.When a pulsesignal is generated, the pulse indicator on the underspeed sliding switch panel flashes once. lt is necessary to ensure that thereis no metallic object on the side of the driven wheel other than the sensing surface that would cause the underspeed slip switchto produce a pulse signal. When the object or torn beltis suspended and swept down to the aviation steel wire rope, the aviationsteel wire rope pulls the tear switch pull ring to make its action, the tear switch sends an alarm or stop signal.
