Dear Mr Richard,

Last month, I purchased a product [name the product] from your company. 


Unfortunately there appears to be a problem with it. On the screen, it displays OL1.  Could you please explain this error message? How can I resolve this problem? 

In your return mail, could you also please  enclose a user manual for this product.

I looking forward to hearing from you soon.

Yours sincerely,

Phuoc

Dear Mr Phuoc,

Regarding your previous mail about the error message OL1 . 

OL1 means Motor Over Load  due to either:

•         Motor running at low speed for a long time under a  heavy drive load
•         Sudden change of load

Possible solutions for the problem:

•         Check or change motor
•         Check and possibly reduce the load

I hope this information has been useful.

I've  attached a .pdf file of the latest user manual for this product as requested.

If the problem persists or you have any other questions, please contact us again anytime.

Best regards,

John Richard
