Macromatic Time Delay Relay Timing Functions
|
|
Function
|
|
On Delay
|
|
Description
|
|
The time delay starts along with the input voltage. The output
energizes after the time delay finishes. Taking out the input
voltage resets the time delay and de-energizes the output.

|
Interval On
|
|
Description
|
|
The output energizes and the time delay starts along with the input
voltage. After the time delay the output is de-energized. Taking out
the input voltage resets the relay.

Function
|
|
Off Delay
|
|
Description
|
|
The output energizes through the use of a trigger, and the time
delay starts when the trigger is taken out. The output de-energizes
after the time delay ends. Re-introducing the trigger while the time
delay is going on will reset it and keep the output energized.

Function
|
|
Single Shot
|
|
Description
|
The output energizes and the time delay starts through the use of a
trigger. Re-applying the trigger during the time delay will not
affect it. After the time delay the output de-energizes and needs
another trigger to re-energize again.

Function
|
|
Flasher OFF
|
|
Description
|
The time delay starts along with the input voltage. Once the time
delay ends, the output energizes and stays energized for another
time delay period. The cycle then repeats itself until the input
voltage is taken out.

Function
|
|
Flasher ON
|
|
Description
|
Works an opposite way compared to Flasher OFF. The time delay starts
and the output energizes along with the input voltage. Once the time
delay ends, the output de-energizes and stays that way for another
time delay period. The cycle then repeats itself until the input
voltage is taken out.

Function
|
|
On/Off Delay
|
|
Description
|
|
Time delay (t1) starts through the use of a trigger, and the output
energizes once t1 ends. The output stays energized after the trigger
is removed for the duration of the time delay (t2). At the end of
t2, the output de-energizes and needs another trigger to start the
sequence again. Taking out the trigger during t1 keeps the output
de-energized and resets the time delay (t1).

Function
|
|
Single Shot Falling Edge
|
|
Description
|
|
Trigger is required to implement the timing sequence. Output stays
de-energized when trigger is introduced and energizes when it is
removed. This also starts the time delay. The output de-energizes
after the time delay, and requires the trigger to be re-introduced
and removed. Reapplying and removing the trigger before the time
delay finishes keeps the output energized.

Function
|
|
Watchdog
|
|
Description
|
|
Works in a similar way to Single Shot Falling Edge. The output
energizes and the time delay starts through the use of a trigger.
The output de-energizes after the time delay, and needs a trigger to
restart the sequence again. Reapplying the trigger before the time
delay finishes keeps the output energized.

Triggered On Delay
|
|
Description
|
|
The time delay starts along with the trigger. The output energizes
when the time delay finishes and will stay that way until the
trigger is removed. Taking out the trigger during the time delay
keeps the output de-energized and resets the time delay.

Function
|
|
Repeat Cycle OFF
|
|
Description
|
|
Time delay (t1) starts along with the input voltage. The output
energizes after t1 ends and stays that way for time delay (t2).
After t2 ends the sequence starts again until the input voltage is
taken out.

Function
|
|
Repeat Cycle ON
|
|
Description
|
|
Works in an opposite way compared to Repeat Cycle OFF. Time delay
(t1) starts and the output energizes along with the input voltage.
The output de-energizes after t1 ends and stays that way for time
delay (t2). After t2 ends the sequence starts again until the input
voltage is taken out.

Function

|
Delayed Interval
|
|
Description
|
|
Time delay (t1) starts along with the input voltage. The output
energizes after t1 finishes and stays energized for time delay (t2).
After t2 ends the output de-energizes and the input voltage has to
be taken out and re-introduced to restart the sequence.

Function

Triggered Delayed Interval
|
|
Description
|
|
Time delay (t1) starts along with a trigger. The output energizes
after t1 ends and remains energized for time delay (t2). After t2
finishes, the output de-energizes and the trigger needs to be
re-introduced to restart the sequence. Removing and re-introducing
the trigger during t1 and t2 has no effect on the output.

|
Function
|
|
True Off Delay
|
|
Description
|
|
The output energizes along with the input voltage. The time delay
starts after the input voltage is taken out and the output stays
energized for the duration, after which it de-energizes.
Re-introducing the input voltage during the time delay will reset
it.

Function
|
|
On Delay/True Off Delay
|
|
Description
|
|
Time delay (t1) starts along with the input voltage. The output
energizes after t1 ends. If the input voltage is taken out, the
output stays energized for time delay (t2), after which it
de-energizes. Input voltage needs to be reapplied to start the
sequence again. Re-introducing the input voltage during t2 keeps the
output energized and resets the t2 time delay.

Single Shot Flasher
|
|
Description
|
|
Time delay (t1), time delay (t2), and the output energizes through
the use of a trigger. The output stays energized for the duration of
t2. After that the output de-energizes for t2, and the cycle repeats
for the duration of t1. Removing the trigger and reapplying it
during t1 will have no effect on the sequence.

Function

On Delay Flasher
|
|
Description
|
|
Time delay (t1) starts along with the input voltage. The output
energizes after t1 ends and stays that way for the duration of time
delay (t2). It then de-energizes for another period of t2, and the
cycle starts again, using the t2 time delay. The cycle keeps going
until the input voltage is taken out.
