Functional Description
1.ON DELAY [0]
Timing commences when supply is present. R
energizes at the end of the timing period.
T-ON and T-OFF can be same or different. The relay
(R) keeps on changing its status until power is
removed.
This function is quite similar to the function ‘1’ but
initially the relay (R) is ON for period T-ON after the
power is applied.
After power ON, R energizes and timing starts. R de-
energizes after timing is over.
Time commences as supply is present and switch B1 is
open. Closing switch B1 pauses timing. Timing
resumes when switch B1 is opened again. R energizes
at the end of timing.
Time commences as supply is present and switch B1 is
closed. Opening switch B1 pauses timing. Timing
resumes when switch B1 is closed again. R energizes
at end of timing.

When supply is ON, R energizes. When switch B1 is
closed timing is suspended and remains suspended till
switch B1 is opened again. Interrupting supply resets
timer.
7. ACCUMULATIVE IMPULSE ON SIGNAL [6]
9.INVERTED SIGNAL ON DELAY [8]
VLL012-00
Timing will commence when supply is present and
switch B1 is open. R energizes after timing. If B1 is
closed during timing period, timing resets to the
beginning of cycle.
11.IMPULSE ON/OFF [a]
Permanent supply is required. R energizes for the
timing period when B1 is opened or closed. When
timing commences, changing state of B1 does not
affect R but resets timer.
When switch B1 is closed or opened for preset time ’T,’
the relay changes its state after time duration T.
12.SIGNAL OFF/ON [B]
A permanent supply is needed. When B1 is closed,
output relay energizes until timing irrespective of any
further action of B1.
13.LEADING EDGE IMPULSE1 [c]
Permanent supply is required. when switch B1 is
closed, and remains closed output relay energizes until
timing is over. If B1 is opened during timing, R resets.
14.LEADING EDGE IMPULSE 2 [D]
15.TRAILING EDGE IMPULSE 1 [e]
Permanent supply required. when B1 is opened, R
energizes and de-energizes when timing is over. If B1
is closed during timing R resets.
16.TRAILING EDGE IMPULSE 2 [f]
Permanent supply is required. When switch B1 is
opened, R energizes and will de-energize when timing
is over. If B1 is pulsed during timing period it Will have
no effect on R.
17.DELAYED IMPULSE [G]
when switch B1 is closed, TOFF starts. Relay energizes
at the end of TOFF period. Then, TON starts
irrespective of signal level and relay de-energize at
the end of TON period.
10.SIGNAL OFF DELAY [9]
Permanent supply is required. R energizes when
switch B1 is closed. Timing commences after S is
opened and then the relay de-energizes.
Permanent supply required. Timing starts when switch
B1 is closed. R energizes at end of timing period and
de-energizes when B1 is opened.
8.SIGNAL ON DELAY [7]
Timing starts only upon signal ‘B1’ transition high to
low. During timing or after completion of Time (i.e.
relay on), any signal transition is ignored. To reset the
timer supply has to be interrupted.
