OFF-time period first

The OFF-time period starts

when power supply is applied.

At the end of the set OFF-time

period, the relay operates and

the ON-time period starts.

At the end of the set ON-time

period, the relay releases and

the OFF-time period starts

again.

This sequence continues until

power supply is interrupted.

ON-time period first

The relay operates and the

ON-time period starts when

power supply is applied.

At the end of the set ON-time
