Maintenance

4.1 Necessity of maintenance

– Necessity of emitter pin cleaning and emitter replacement
In general, when static controllers are continuously in operation for a long period, dust and dirt are accumulated around the emitter pin, called “fuzzy-ball’.
Depending on operating environment, ‘fuzzy-ball’ grows to block normal ion emission and results in deterioration in performance of static controller.
An emitter pin (inside a emitter) is a sharp, pin-shaped object, made from tungsten.
ASM-A Series produces ions using Corona Discharge method. Thus, during an operation, high voltage is applied on its emitter pin, which rounds the sharp pin away as the time goes on. A rounded emitter pin cannot produce ion as well as the sharp one.
For these reasons, emitter and emitter pin should be cleaned and replaced periodically.
If not cleaned, and replaced properly, worn-out emitter pin with fuzzy-balls, may deteriorate the quality and performance of your production. Make sure that emitter  (and emitter pin) should be cleaned and replaced on a regular basis.
– Recommended cleaning cycle under the circumstance below : Every 6 months
– Temperature : 22 ℃[a higher temperature may lengthen the cycle] – Humidity : 50%[a higher humidity may lengthen the cycle] – Clean Class : 10,000 Class [a lower Class index may lengthen the cycle] – Quality of Supplied Air : CDA[purer air may lengthen the cycle] ※ The conditions listed above are for general environment, Actual result may slightly vary depending on the user’s working environment.
Six months cleaning cycle is based on test conditions used by DIT. Please compare DIT’s conditions and your working environment and adjust it and set up cleaning cycle accordingly.

4.2 Cleaning and replacement of emitters
– How to clean an emitter

① Prepare soft brush or cotton swab with alcohol.
(No acetone)
② Power off the device and stop the air feeding.
③ Wipe out the white ‘Fuzzy ball’ on the end of the emitter pin softly enough not to damage or scratch it.
④ Power on the device and feed the air
⑤ After 5 ~ 10 minutes, check the device performance with and measuring instrument.

– How to replace an emitter

① Prepare a new emitter for replacement.
② Power off the device and stop the air input.
③ Rotate the emitter assembled in the Unit counterclockwise
④ Pull the emitter to separate it from the Unit
⑤ Insert a new emitter and rotate it clockwise to fix it firmly.
⑥ Power on the device and feed the air
⑦ After 5 ~ 10 minutes, check the device performance with and measuring instrument.
