Time Setting
Mode of Operation
The output relay is normally in
the neutral centre position.
When power supply is applied,
the relay is switched to star
position (pin 16) and the star
time period starts.
At the end of the set time
period, the relay returns to
neutral centre position and the
set delay between star and
delta position starts.
At the end of the delay (ad-
justable 50 - 130 ms), the re-
lay is switched to delta posi-
tion (pin 18) and will not re-
lease until power supply is in-

terrupted for at least 100 ms.
If power supply is interrupted
for at least 100 ms before the
star time period has expired,
the relay will not operate and
the time circuit is reset to zero.
The relay is ready for a new
time period.
