TON
While the device is energized,
If START is active, relay is energized after delay time
(TOFF).
While the device is energized,
If START input is active, relay becomes Off and On
periodically during TOFF and TON times respectively.
At the end of each TON time START input is checked.
If it START is passive, timer stops and initial conditions
are returned. Otherwise, periodic operation continues.
While the device is energized,
With an impulse at the START input, relay becomes On
during TON time. Then, relay becomes Off.
With an impulse at the START input, relay becomes On.
However, timer do not counts while START is active.
When START becomes passive, relay becomes Off after
a time delay (TON).
While the device is energized,
If START input is active, relay becomes first Off and then On
periodically during TOFF and TON times respectively.
As soon as START becomes passive, timer stops and initial
conditions are returned.
NOTE: if Gate input becomes active, timer enters into wait mode. Timer waits at that condition until gate input becomes passive

TON: Relay On time
TOFF: Relay Off time
t: Partial time of TON or TOFF.
: Indefinite time
While the device is energized,
If START input is active, first TON and then TOFF times are
passed periodically.
As soon as START becomes passive, timer stops and initial
conditions are returned.
While the device is energized,
If START input is active, relay becomes On
during TON time. Then, relay becomes Off.

If START is active, relay is energized after delay time

timer waits for another active signal at the START input
to complete the TOFF time.

While the device is energized,
If START is active, relay is energized after delay time
(TOFF).
If START becomes passive before TOFF time,
timer waits for another active signal at the START input
to complete the TOFF time.
If START becomes passive after TOFF time, reset occurs.
Relay is de-energized and initial condition is returned.
