2. The start-up method for the auto tuning
① During the dry unit operating, starts the auto tuning when push continuing △ and ▽ key at
the same time for 2 seconds during display of the dry temperature measurement value.
(During auto tuning, displays alternately at the period in 1 second in the measurement
temperature and
「At」)
② When the auto tuning ends, returns to usual PV display and starts PID control by the adjustment
result.
③ The operation when stopping auto tuning compulsorily is the operation that is the same as ①
completely.
※ Because this controller isn't displaying an error in the auto tuning, when the auto tuning
error occurs, (when a sensor is broken or the auto tuning time passes for equal to or
more than 3 hours) doesn't perform the display and the buzzer alarm operation.
Also, when the auto tuning error occurs once, in the power, unless restarting, it isn't
possible for the auto tuning to be again.
3. About influence of gas that occurs from the resin
○The information on influence of gas that occurs from the resin
The unit sometimes can not function normally with influence of gas that occurs from the resin.
As for the resin that has this possibility, the compatible to suppress influence of gas becomes necessary.
There are methods of non-paint specification and special exhaust (exhaust cyclone) etc. in compatible
method. However, the method must be chosen by the dry material.
Also, there is not the complete measure to all resins in the present.
Therefore, depending on the using resin, the constant regular maintenance and the parts replace of
consumables become necessary.
When the following phenomenon is confirmed in during use, there is possibility that the unit undergoes
influence by gas. In such case, please consult to us.
1) In case of the liquid of oily oozes from the exhaust filter box, the pipe connection part and the dry
hopper etc, and the paint breakaway.
2) The inside of exhaust filter case, filter and dust tube etc is discolored.
3) The thin smoke occurs from the exhaust filter.
4) Oil dirties the whole unit.
5) Oil adheres to the floor.
○As for the resin that influence of gas is estimated, refer to the list of next page.
