Mode of Operation
The output relay is normally
in the neutral centre position.
When the power supply is
applied, the relay switches to
star position (pin 16 or 4)
and the star period starts.
At the end of the set time
period, the relay returns to
the neutral centre position
and the set delay between
star and delta position starts.
At the end of the star to
delta delay (adjustable from
50 to 130 ms), the relay
switches in delta position
(pin 18 or 3) and does not
release until the power sup-
ply is interrupted for at least
200 ms.
If the power supply is inter-
rupted for more than 200 ms
before the star time period
has expired, the relay does
not operate and the time cir-
cuit is set to zero. The relay is
ready for a new time period.

scale: 1 to 10 with respect
to the chosen range.
