Reset on Factory Setting:
In case of any of parameter is not in
it`s proper range or it has been disturbed any how, the controller could
be reset on default factory settings.
Manual capacitor Switching:
`UP` and `DN` keys are also provided
an additional function to manually switch on and off the stages.
This is not a permanent function, the apfc controller will follow the normal
automatic working rule after releasing the key.
Capacitor Recommendation:
It is strongly recommended that the
capacitor should be in ascending order from stage output 1 to stage output
15 for perfect result.
Example- 1, 2, 4, 8 and so on.
Dead Band Explanation:
Dead Band
is provided for, to prevent
frequently switch on/off the stages on small variation of power
factor. It could be understand by the figure as given below.
Power factor is set to 1.00 and dead Band is set to 2. The controller will start to switch on the stages when power
factor is below than 0.98 (1.00-2=0.98) in lag side and start to switch off the stages when power factor is below
than 0.98 in lead side. In between the controller will hold the stages that would be `no action zone`.
