Operation of the easy circuit configuration
[t-head1-nnp]
Start/stop the circuit with the external pushbuttons S1and
S2. The mains protection starts the time relay in easy.
I1: Mains protection switched on
Q1: Star contactor ON
Q2: Delta contactor ON
T1: Changeover time star/delta (10 to 30 s)
T2: Waiting time between star contactor off and delta
contactor on (30, 40, 50, 60 ms)
If your easy has an integral time switch, star/delta
starting can be combined with the time switch. In this case,
use easy to also switch the mains contactor.
