Operating Mode & Description Timing Diagram
MODE - 00: ON DELAY
On application of the supply voltage, the preset time
duration (T) starts. On completion of the pre-set time,
the output is switched ON & remains on till the supply
voltage is present.
MODE-01: ON DELAY CONSTANT SUPPLY TYPE 2
Timing will commence when the supply voltage is applied
and input signal removed. After the time period has elapsed,
output is switched ON. If signal is applied during the timing
then the timing stops. Timing will restart only when signal
is removed again. Therefore there are two methods this
timer can be controlled, either by application or removal
of signal input and with the interruption of the supply
voltage to the timer with signal removal.
MODE-02: ON DELAY CONSTANT SUPPLY TYPE 3
A permanent supply voltage is required. The timing period
starts when the signal is present and will continue irrespective
of any further changes to signal input.
After the time period has elapsed output is switched ON.
Signal change has no effect during timing period. To reset
the timer, signal must be removed and then closed once again.
MODE-03: ON DELAY (CONTROL SWITCH RESETTABLE)
When the supply voltage is applied and signal is present, the
timing function starts. If signal is removed and present again
during the preset timing then timing is restarted and output
stays OFF. After preset time has elapsed the output is ON.
MODE – 04: SIGNAL ON DELAY
Time commences as supply voltage and signal is present.
When input signal is absent, the timing resets. The output is
switched ON at the end of the preset time duration (TOFF).
When output is ON if signal is absent then output switches OFF.
MODE - 05: INVERTED SIGNAL ON DELAY
When supply voltage is applied and if signal is absent then
the preset time duration (TOFF) starts. On preset time
completion, the output is switched ON. If signal is present
during timing period, then timing stops and timing restarts
when signal is removed.
MODE -06: INVERTED SIGNAL ON DELAY TYPE 2
When the supply voltage is applied and input signal is absent,
the preset time duration (TOFF) starts. After the time period
has elapsed, the output is switched ON. Signal change has no
effect during timing period. Output stays ON until supply
voltage has been interrupted.
MODE – 07: SIGNAL OFF DELAY
When the supply voltage is applied & input signal present, the
output is switched ON. When the signal is absent the preset
time duration commences & the output is switched OFF at
the end of the preset time duration. If signal is present during
timing period, then timing stops and timing restarts when
signal is absent again.
MODE-08: OFF DELAY CONST. SUPPLYTYPE 2
A permanent supply voltage is required. When the input signal
is present the output is switched ON immediately. When input
signal is removed the timing period starts. After the time period
has elapsed output is switched OFF. Once the timing period has
started further changes in the input signal will have no effect.
However once the timing cycle has been completed the process
may be started again by closing input signal. While the timer is
executing the only way to reset the timer is to interrupt the
supply.
MODE - 09: CYCLIC ON/OFF
On application of supply voltage, the output is initially switched
ON for the preset 'ON' time duration (TON) after which it is
switched OFF for the preset 'OFF' time duration (TOFF).
This Cycle repeats and continues till supply is present.
MODE - 10: CYCLIC OFF/ON
On application of supply voltage, the output is initially switched
OFF for the preset 'OFF' time duration (TOFF), after which it is
switched ON for the preset 'ON' time duration (TON).
This Cycle repeats and continues till supply is present.
MODE-11: ASYMMETRIC CYCLE PULSE START
A permanent supply voltage is required. The timer function is
triggered by the input signal. When input signal present the
output is switched ON while the first preset time period (TON)
elapses. Once this time period (TON) has elapsed output is
switched OFF for the second preset time (TOFF) period. Once
this second time period (TOFF) had elapsed then output
switched ON and the cycle will start from the beginning again.
If input signal is opened during timing (TON or TOFF) the cycle
will stop and output is switched OFF, cycle will start with output
ON state when the input signal present again.
MODE-12: ASYMMETRIC RECYCLER PULSE START
TYPE 2
A permanent supply voltage is required. The timer function is
triggered by input signal. When input signal is present the output
is switched OFF while the first preset time period (TOFF) elapses.
Once this time period has elapsed output is switched ON for the
second preset time period (TON). Once this second time period
(TON) had elapsed then output is switched OFF and the cycle
will start from the beginning again. If input signal is absent
during timing (TON or TOFF) the cycle will stop and output is
switched OFF, cycle will start with output OFF state when the
input signal present again.
MODE – 13: SIGNAL ON OFF DELAY
On application of signal the preset time (T) starts. After this
preset time has elapsed, output is switched ON. During this
timing, if signal is absent then output is switched ON
immediately and OFF delay is started. Once this time period
has elapsed the output is switched OFF. During this OFF delay
if signal is present again the output switched OFF immediately
and ON Delay restarted.
MODE –14: SIGNAL ON OFF DELAY TYPE 1
On application of supply voltage & input signal the preset time
(T) starts. After this preset time has elapsed, output is switched
ON. During this timing, if signal is absent then output is
switched ON immediately and preset timing is restarted.
Opening the signal during this timing suspends timing but does
not reset the time sequence. Timing will resume immediately
when signal is present again. Therefore, total time taken before
the delayed contact changes state is the preset time plus any
time that the signal is opened. Once this time period has
elapsed the output is switched OFF.
MODE – 15: SIGNAL ON/OFF Type 2
On application of input signal, the preset delay time period (T)
starts. During this timing if signal is removed then timing is
stopped and timing will be restarted when signal applied again.
After this time period has elapsed output is switched ON.
On removal of input signal, the preset time period starts again
& the output is switched OFF when the preset time duration is
complete. Output stays OFF until supply voltage has been
interrupted.
MODE - 16: IMPULSE ON ENERGIZING
On application of supply voltage, the output is instantly switched
ON for the preset time duration (TON) after it is switched OFF.
MODE - 17: IMPULSE ON/OFF
When supply voltage is applied and on closing or opening of
input signal, the output is switched ON & the preset time duration
starts. On completion of the time duration the output is switched
OFF. During timing period, changing the state of the input signal
dose not affects output but resets time.
MODE – 18: ACCUMULATIVE DELAY ON SIGNAL
On application of supply voltage, the preset timing duration
commences. When input signal is present, the timing pauses &
resumes only when the input signal is absent. The output is
switched ON at the end of the preset time duration (TOFF).
Operating Mode & Description Timing Diagram
MODE - 19: ACCUMULATIVE DELAY ON INVERTED
SIGNAL
Time commences as supply voltage is applied and signal is
present. When input signal is absent, the timing pauses &
resumes only when the input signal is present again. The output
is switched ON at the end of the preset time duration.
MODE - 20: ACCUMULATIVE IMPULSE ON SIGNAL
On application of supply voltage, the output is switch ON & the
preset timing duration commences. When input signal is present,
the timing pauses & resumes only when the input signal is absent.
The output is switched OFF at the end of the preset duration (TON).
MODE - 21: LEADING EDGE IMPULSE
On application of supply voltage & input signal, the output is
switched ON for preset time. After completion of preset time
period, output is switched OFF. If the input signal is applied or
opened during preset timing period, the output and timing
remains unaffected.
MODE - 22: LEADING EDGE IMPULSE 2
On application of the input signal the output is immediately
switched ON. The output remains ON for the preset time duration
(T) after which it is switched OFF. If the input signal is absent
during the pre-set time, the output immediately switched OFF.
MODE - 23: TRAILING EDGE IMPULSE
When the supply voltage is applied and input signal is absent,
the output is switched ON for the preset time duration (T).After
completion of preset time period, output is switched OFF. If I/P
signal is present during the preset timing period then output is
switched OFF & timing stops.
MODE - 24: TRAILING EDGE IMPULSE 2
When the input signal to the timer is absent, the output is
immediately switched ON for the preset time duration (TON)
after which it is switched OFF. If the input signal is present
during the pre-set time, the output remains unaffected.
MODE - 25: DELAYED IMPULSE
On application of supply and input signal, the preset 'OFF' time
duration (TOFF) starts. The output is switched ON at the end of
preset 'OFF' time duration. Then the preset 'ON' time starts
irrespective of the signal state & ON till the completion of ' TON'.
During the output OFF period if signal is present then timing is
restarted, but output is unaffected. The signal change has no
effect during time period (TON).
MODE-26: DELAYED IMPULSE TYPE 2
A permanent supply is required. When signal is present the output
will remain OFF while the first preset time period (TOFF) elapses.
Once this time period has elapsed the output is switched ON for
the second preset time period (TON). Once this second time period
(TON) had elapsed then output is switched OFF and cycle stops.
Output stays OFF until supply voltage has been interrupted.
During timing period (TON or TOFF) if signal is absent then output
is switched OFF and the cycle stops, cycle will start with output
OFF state when the input signal present again.
MODE-27: DELAYED PULSE (CONSTANT SUPPLY)
POWER BASED
The timing period (TOFF) starts when the supply is applied to the
timer. After the preset has elapsed output is switched ON for the
preset pulse (TON) duration. To reset the timer the supply has to
be interrupted. If this interruption occurs during the pulsed
output (TON) then the output is switched OFF and the timer will
reset.
MODE-28: DELAYED PULSE (REMOTE TRIG.)
The timing period (TOFF) will start when input signal is closed with
the supply connected. After preset time (TOFF) has elapsed the
output is switched ON for the per-selected pulse (TON) duration.
To reset the timer either input signal needs to be removed or
supply has to interrupt. If this action occurs during the pulsed
output cycle (TON) then output is switched OFF and the timer
will reset.
MODE-29: DELAYED PULSE (CONST. SUPPLY TYPE 1)
Supply to the unit must be continuous. On application of input
signal the time period 'TOFF' starts to run. On completion of 'TOFF',
the relay output is switched ON immediately and the time period
'TON' starts to run. On completion of 'TON' the output is switched
OFF. The input signal has no effect until 'TOFF' or 'TON' have
completely expired.
MODE-30: ON PULSE (CONTROL SWITCH
RESETTABLE)/ WATCH DOG TYPE
When the supply is connected and signal is applied, output is
switched ON and the timing function starts. If signal is removed
and applied during the preset timing then timing is restarted and
output stays ON. After preset time(TON) has elapsed the output
is switched OFF
MODE – 31: ON PULSE (SUPPLY RESET)
On application of supply voltage the output is switched ON. The
first pulse of input signal starts the preset time period. Receiving
pulses during the time period extends it and output stays ON.
Receiving no signal pulses during the time period completes it
and output is switched OFF. Output stays OFF until supply
voltage has been interrupted.
MODE – 32: Leading Edge Bi-stable or Step Relay
After every signal, the output contact changes their states,
alternately switching from open to close & vice versa.
Important Note:
As per the timing diagram this mode is not time base mode,
hence ideally there is no need to enter the time. But if we have
select action on Signal present as relay ON continuously, then
as per flow chart of the TDT2 (Action on Transition during Run
Time) will not shown. So select relay on time maximum
i.e. 999 Days.

MODE – 33: Forward- Reverse Mode With total time
Note: 1) Cycle will start if signal is high at Power ON or signal
transition occurs from low to high. 2)Total time and cycle will
restart when signal transition occurs from low to high.3) There
will be no change in Timer status if signal transition occurs
from high to low. 4) After completion of one cycle (when total
time counting is complete), cycle will start again when signal
transition occurs from low to high.
A permanent supply voltage is required. The timer function is
triggered by input signal. When input signal is present then both
output are switched OFF for first pause time period (P). After
completion of pause time period then output R1 is switched ON
(R2 OFF)for the second preset time period (t1). Once this
second time period (t1) had elapsed again output R1 is switched
OFF. After completion of next pause time (P) period then output
R2 is switched ON for the third preset time period (t2). Above
cycle will repeat for total time duration (T).
MODE – 34: Forward- Reverse Mode Without total time
A permanent supply voltage is required. The timer function is
triggered by input signal. When input signal is present then both
output are switched OFF for first pause time period (P). After
completion of pause time period then output R1 is switched ON
(R2 OFF)for the second preset time period (t1). Once this
second time period (t1) had elapsed again output R1 is switched
OFF. After completion of next pause time (P) period
then output R2 is switched ON for the third preset time
period (t2).
Note:1) Cycle will start if signal is high at Power ON or signal
