Mode of Operation
Example 1
Aut. start with relay ON
The relay operates and the time
period starts when power sup-
ply is applied.
If an input pulse is received
before the end of the set time
period, the relay continues
Example 2
Start with relay OFF
The relay operates and the
time period starts at the lea-
ding edge of the first input
pulse.
If a new input pulse is received
before the end of the set time
operating for a full new time
period starting at the leading
edge of the input pulse.
If the set time period expires
before a new input pulse is
received, the relay releases.
period, the relay continues
operating for a full new time
period starting at the leading
edge of the new input pulse.
If the time expires before a
new input pulse is received,
the relay releases.
