3.5 Trimmers
There are trim ers the side the device setting and axim um
voltage thresholds and tim delays.
This can used hen safe xiliary pow supply available pow the
c irc breaker otor operators.
The single/three phase setting made using itch num ber 6.
W ith strategy the itch ing sequence follow s:
- net anom aly detected
- norm line irc breaker opened and the gen set started
- delay til gen set supply available after the gen set circu it
breaker closed.The voltage ratings refer to:
- phase-to-neutral voltage the case single-phase operation
- phase-to-phase voltage case three-phase operation. The itching
sequence follow s:
- net anom aly detected
- gen set started
- delay til gen set supply available after the norm circu it
breaker opened
- gen set irc breaker closed.
N ork frequency
The netw ork frequency set using dip itch num ber Frequency
thresholds ill autom atically set +10% the rated value.
W hen the electric auxiliaries are powered dire ctly fro the net and gen set, this
sw itching strategy indispensable because safe pow supply the auxiliaries is
not available.
S itching strategy
D epending the application the ATS010 used, different
sw itching strategies can applied.
The itching strategies explained detail Chapter aturally
the connection diagram iffe according the strategy used.
W ith strategy before com anding irc breakers, the ATS010 aits one f
the pow supplies become available: norm gen set.
