High-temp. release

1) The heating operation is performed as follows based

 

 

control

on the detected temperature of Tc sensor or Tcj sensor.

 

 

 

• When [M] zone is detected, the commanded frequency

 

 

 

is decreased from the real operation frequency.

 

 

 

After then the commanded frequency changes every

 

 

 

30 seconds while operation is performed in [M] zone.

 

 

 

• In [N] zone, the commanded frequency is held.

 

 

 

• When [L] zone is detected, the commanded fre-

 

 

 

quency is returned to the original value by approx.

 

 

 

6Hz every 60 seconds.
