Mode of Operation

The output relay is normally

in the neutral centre posi-

tion. When the power supply

is applied, the relay switch-

es to star position (pin 16)

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)

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 peri-

od.
