At start of Auto Initialization display shows "Ato"
1. Auto Init enables detection of phase correction angle between voltage and
current , number of capacitor bank and capacitor bank kVAr connected.
Auto option will become "No" automatically once auto initialization is completed
successfully.
2. For successful auto init voltage should be healthy, otherwise Auto Init will be
terminated and display shows "InP" and test is aborted.
3. For detection of phase correction angle the power factor should be in range
of 0.6 Lag to 0.99 Lag. if detected successfully then display shows angle on
screen.
4. Load conditions are stable and No error detected then average of three
attempts of capacitor bank kVAr values is calculated by switching capacitor
bank one after other. and three attempts are made to get capacitor bank kVAr
values.
during capacitor switching the attempt
number with bank position is shown
followed by capacitor kVAr value
measured."A-P" indicates Auto Init
Pass and "A-F" indicates Auto Init Fail
5.During Auto init Screen displays
"Ato" followed by "diS" at power on
Auto Init will be started after Discharge
time delay. if auto int fails due to some
reason then after predefined time or at
each Power On it will be re attempted.
