8-2．转速侦测说明 |
|
|||||||
|
|
Output waveform: square wave.
When the voltage value is higher (Voltage Y)then output waveform is higher
When the fan is shutdown then output waveform is a horizontal line
The cyclic distance is longer then the RPM is slower.
RPM formula as follows:
RPM= 60000
X（ns）
<例>Example X=15 Ls=1000ns
Lmin=60000ns
RPM = 60000 =4000

9．注意事项（Notes） |
|
|||||||
|
|
9-1．使用时请勿超出本规格所规定之极限，否则我们不保证此产品。 We,JYD Co;LTD will not guarantee the products if the application of our products are exceeded the Limitation which is specified on the specification.
9-2．倘若要变更此份文件的任何规格，请务必事先提出要求 In case of changes of the specification specified on this document. A WRITTEN NOTICE IS REQUESTED IN ADVANCE。
9-3．请勿触压着叶片以及电源线缠绕着风扇或用力拉扯电源线，如此轴心与电源线将会被损坏 please do not touch the impeller with the pressure and never bring the fan with lead wire .The bearing and lead wire may be damaged.
9-4．本产品不保证因粉尘、水滴、小虫进入，而影响寿命与不良产生 No guarantee on the products against the safety problem or failure caused by powder dust, drop of water or insect.
9-5．如有任何资料及文件与此份不同，将以此份资料为主要参考 If there is any data or related documentation different from this data sheet.This data sheet is the principle Reference
9-6．请勿在可燃性气体与任何有害环境中使用 Please do not use the fan in the environment of corrosive gas or liquid or any detrimental gas
9-7．请于六个月内使用，否则风扇存放在很高温或很低温及湿度很高的室温中，风扇于六个月后将可能 会有漏电流产生。 Please do not store the fan in the environment of high/low temperature, high humidity or detrimental gas Please store within six months ,every six months , shall be a leakage of electric current to the fan even Though the fan is stored in room temperature.
9-8．当风扇于运转中，请勿企图将风扇锁死特别长的时间。如此，会因连续停止不转，产生高热而烧毁 风扇 While the fan is in operation, please do not look the fan intentionally for a long period of time,since the Continuous stoppage will result in overheat and thus burnt out the fan.
9-9．组装风扇时，请特别注意，因共振或振动产生的噪音 During the installation of the fan , please pay substantial attention to possible notice caused by resonance Vibration and shock.
9-10．当搬运或作业中，风扇如从60cm的高度落下，将会对叶片的平衡产生若干影响，特别是滚珠轴承 避免掉落。 It is very important to notify that avoid to drop from 60cm height when in any movement or operation, it Will impact the balance of balance of blade . Especially ball bearing structure is avoided to drop down.
9-11．锁外壳之螺丝扭力不得超4kg/f. The torque of the screw that locked the frame should not exceed4kg/f. |
