For the dryer to control temperature properly, three parameters must be set:
S
Proportional band (P) heat
S
Integral (I) heat
S
Derivative (D) heat
These parameters make up the PID loop that controls the duty cycle used to
regulate the amount of power applied to the induction coil. PID settings for
your dryer are optimized to provide the best possible response (fastest rise
time with minimum overshoot).
The default settings are:
Proportional:
40
Integral:
8.30 seconds
Derivative:
0.50 second
Sample Time:
0.2 second
To adjust these settings, touch the desired field and use the keypad to set a
new value. Touch the
ENT
key to save your settings.
