Hot air drying oven

Hot air drying oven

 ——Microprocessor control (with timing function)

USER’S MANUAL 

ZHEJIANG SUJING PURIFICATION EQUIPMENT CO.,LTD.

Summary:Provided to industrial and mining enterprises,

laboratories and scientific research in stitutes for desiccation,forrefaction, wax-melting and sterilization.

Futures

1、Intreior of oven is made of specular stainless steel by argon-arc-welding technics,and the exterior of oven is made of

high-quality steel sheet with a beautiful and novel appearance.

2、Microprocessor PID tem perature controller with tem perature control protection,digits display and timing function ensures a precise and reliable tem perature control.(intelligent programable LCD temperature coneroller is an option)。

3、Hot-air circulating system consists of a fan keeping running under a high tem perature and proper air ducts to ensure a uniform distribution a high tem perature in chamber。

4、Independent alarm system for temperature-limiting ensures experim ents run safely and no accident would happen.

How to use

1、Power start

2、Temperature setting：Press SET key，SV screen flicker，be ready to change the temperature setting value shift key →、↑、↓changing temperature setting value, Press SET key again to return to functional mode.

3、System parameter revises：Press SET key for more than 5 seconds，PV demonstrates RLI (SV demonstrates parameter value) ，press SET key for many times，then you can see PV displaying symbol and revising parameter value，press SET key for more than 5  seconds to return to functional mode.

4、Temperature error amendment：For instance：When we set the temperature 300 degree，then it shows 300 degree，but if we use the thermometer to find there is 290 degree in the inner box，then we should ccorrect the system parameter as “—10”，in shis way can make the monitoring instrument show 290 degree at the same time，thus to be consistent with the theremoter in the inner box.

5、Timing  function ：The monitoring instrument has no timing function when the parameter “T” is “ 0”，and when we set the parameter “T” is “ 100”，time is  100 minutes. Notes that be allowed to revise “T” value again guring the working period，but user should remember that the machine should be start again to ensure that the revised value be effected .

6、When we want to revise the system parameter，it is necessary to ensure the final item “LCY” to be  “0000”，only the “LCY ” to be “0000” then it is possible to revise the other parameters.
