2.1 – SET POINTS PROGRAMMING
The instrument permits to program up to 3 time sets: “t1”, “t2”,
“t3”.
To program this times do proceed as follows :
Pushing key P and keeping it pushed for 1 sec. approx., the display
will visualize “t1” and led SET/CNT will blink rapidly.
Releasing the key, on the display will be visualized the programmed
Set Point “t1”.
To modify it, work on keys UP, to increase the value or on key
DOWN, to decrease it.
If the programmed functioning mode require the set “t2” (F1 = 3, 4
or 5), for programming this pressing key P again and the display will
show “t2”.
Releasing the key, on the display will be visualized the programmed
Set Point “t2” and will be possible to modify it by the key UP or
DOWN.
If the programmed functioning mode require the set “t3” (F2 = 3 o
4), for programming this pressing key P again and the display will
show “t3”.
Releasing the key, on the display will be visualized the programmed
Set Point “t3” and will be possible to modify it by the key UP or
DOWN.
The outgoing from the set points programming it’s automatically
obtainable not working on any key for 5 sec. approx. or pressing
only one time the key U, thus the counting value willl again be
displayed.
The programming of the set times is always possible, both with
counting on or off.
The display will go back to the normal functioning, the parameters
will not be accessible anymore and it will only be possible to modify
the Set Point.
To have again access at the parameters, repeat the same
procedure pushing key P and selecting "uL" ; finally go out from the

expressly allowed by the above mentioned rule has
to foreseen proper protection devices.
The instrument CAN’T be used in environments with dangerous
atmosphere (flammable or explosive) without a proper protection.
It has to be reminded that the user has to take care that the
electromagnetic rules are being respected also after the instrument
installing, eventually using proper filters.
Whenever a failure or a bad functioning of the instrument may
cause dangerous situations or damage to people, things or animals
it has to be reminded that the plant has to be equipped with
additional electromechanical devices in order to grant the safety.
3.2 – MECHANICAL MOUNTING
The instrument, in DIN case 72 x 72 mm, is designed for flush-in
panel mounting.
Make a hole 66,5 x 66,5 mm and insert the instrument, fixing it with
the provided special brackets.
We recommend to mount the gasket to obtain the front protection
degree as declared. Do avoid to place the instrument in ambient
with very high humidity or dirt that may create condensation or
introduction into the instrument of conductive substances.
Ensure the adequate ventilation to the instrument and avoid the
installation within boxes where are placed devices which may
overheat or have as a consequence the instrument’s functioning at
higher temperature than allowed and declared.
Connect the instrument as far as possible from source of
electromagnetic disturbances so as motors, power relays, relays,
electrovalves,etc.
3.3 – ELECTRICAL CONNECTIONS
Carry out the electrical wiring connecting only one wire for each
terminal , according to the following diagram, checking that the
power supply is the same as indicated on the instrument and the
loads current is not higher than the maximum current admitted.
The instrument, being a built in equipment with permanent
connection into a cabinet, is not equipped neither with switches nor
with internal devices protecting from overcurrent : the installation
shall employ a two-phase circuit-breaker, placed as near as
possible to the instrument, located in a position easily reachable by
the user and marked as instrument disconnecting device.
It's recommended, furthermore, to properly protect all the electric
circuits connected to the instrument, with devices (ex. fuses)
proportionate to the circulating currents.
It's strongly recommended to use cables with proper insulation,
according to the working voltages and temperatures.
Furthermore, the input cable of the probe has to be kept separate
from line voltage wiring. If the input cable of the probe is screened, it
has to be connected on the ground with only one side.
When you choose the "b" parameter with option 2 (timer goes on
operating in case of power failure) is necessary to check that the

3.4 - ELECTRICAL CONNECTION DRAWING
F1 = 2 - FEEDTHROUGH :
On receiving the START signal, the instrument enables the output
OUT1.
The output is disabled when the set time value “t1” has been
reached.
The output will be enabled again after the transmission of a RESET
signal and a subsequent START signal.
F1 = 3 - ASYMMETRICAL OSCILLATOR START ON:
This operating mode allows the user to enter two SET times “t1” and
“t2”, and therefore also involves the "S2" parameter .
On receiving the START signal, the output OUT1 is immediately
enabled and remains enabled for the time period t1.
4 - OPERATING MODE
Then the output is disabled and remains disabled for the time period
t2.

U, or through the remote inputs CNT EN and RES.
The operating mode of the key U is defined by the parameter "t",
the operating mode of the input CNT EN is defined by the parameter
"E" while the input RES always works as reset, i.e. it stops and
resets the counting when it is activated and moreover it has priority
on the other commands (when it is activated it doesn't allow the
starting of the counting).

4.2 – FUNCTIONING OF THE DISPLAY
The led SET/CNT is used to indicate the access into the
programming (flashing fast), the counting in action (flashing each
second), the counting interrupted before the term (lighted fixed) or
the counting finished and the state of reset (off).
After the reset, the display visualizes 0000 if the counting mode is
programmed as UP (par. "C" = 1) or it visualizes the programmed
set value if the counting mode is programmed as DOWN (par. "C" =
2).
During the counting, the display visualizes the value of time that
spends in UP or in DOWN mode.
If the back-up mode has been programmed to continue the counting
in action without power supply, the display remains lighted but with
an inferior brightness (with the purpose to limit as much as possible
the absorption from the battery).
Then the output is enabled.
The output is disabled again when the set time period “t2” has
expired. This procedure goes on until a RESET signal is transmitted.
F1 = 5 - ONE CYCLE ASYMMETRICAL OSCILLATOR START OFF:
The operation results similar to the "F1"=4 with the only difference
that only one cycle of OFF/ON is performed.
To the start signal the output OUT1 remains disabled for the time
“t1".
4.3 - OUT1 OPERATING MODE
When the time “t1” is expire the output will be on for the time “t2”.
The instrument can be programmed by the parameter "F1" to The cycle will be enabled again after the transmission of a RESET
signal and a subsequent START signal.

F1 = 1 - DELAYED :
On receiving the START signal, the instrument starts counting time.
When the set time value “t1” has been reached, the instrument
enables the output OUT1.
The output is disabled by the RESET signal.
TECNOLOGIC spa - TT 73 - OPERATING INSTRUCTIONS - Vr. 01 - ISTR 06083 - PAG. 3
4.4 - OUT2 OPERATING MODE
The instrument can be programmed by the parameter "F2" to
operate in any of the following 4 modes:
F2 = 1 - Output OUT2 operating like OUT1
The output OUT2 exactly operates like the output OUT1 so that to
be able to have two output contacts.
F2 = 2 - Output OUT2 operating as instant contact
The output OUT2 is activated during the counting phase and
remains activated to the reset command.
F2 = 4 - Same function of OUT1 (time t1) with time t3 relative to t1
(in advance) : The choice of this mode of operation enable the set
"t3" that it has the same range time "S1" and cannot be higher of
"t1."
Received the start signal the instrument begins the counting and
exactly operating on the output OUT 2 in the same way with which it
operates the function F1 on the output OUT1.
If F1 = 1, 4 or 5 the output OUT 2 operate with the function of delay
with the time [”t1” - "t3"] while if F1 = 2 or 3 the output OUT 2
F2 = 3 - Same function of OUT1 (time t1) with time t3 absolute:

If F1 = 1, 4 or 5 the output OUT 2 operate with the function of delay
with the time "t3" while if F1 = 2 or 3 the output OUT 2 operate with
the feedthrough function always with the time "t3."
In the programming mode of the time "t3" the display shows "t3 i" to
indicate that the time t3 is independent.
If “F2” = 0 the output OUT 2 is always disabled.

4.5 - CNT EN INPUT OPERATING MODE
The start signal can be given by the frontal key U programmed as
START/STOP function (“t”=1 or 2), which normally has bistable
functioning, or by the CNT EN input count enable.
As regards the CNT EN input, which enables time counting, the
instrument can be programmed to operate in any of the following 4
modes:
E = 1 - BISTABLE START/STOP:
After resetting the timer using the RESET input, close the CNT EN
contact to start the timer. Now release the contact.
When the contact is closed again, the timer stops on the current
counting value.
The timer starts again following another impulse to the CNT EN
input port.
This procedure goes on until a RESET signal is transmitted or the
set time period has expired.
E = 4 - MONOSTABLE RESET-START/STOP:
By closing the CNT EN input and keeping it closed, the timer is
resetted and starts the counting, at the opening of the CNT EN input
the counting is stopped.
This operating mode is recommended when the user wants to
control the timer using voltage signals. In fact, with an appropriate
interface (eg. an external relay) the timer is reset and starts counting
when voltage is supplied, and stops when voltage is cut off (just like
a conventional timer).
In this functioning mode the U frontal key works only as reset.
5 - PROGRAMMABLE PARAMETERS
5.1 - PARAMETERS TABLE
E = 2 - BISTABLE RESET-START/STOP:
This operating mode is very similar to that of the front START/STOP
key and dipends also from "t" parameter which has 2 possible
functioning modes:
E = 2 , t = 1 - RESET-START/STOP:
The first impulse on CNT EN input reset and start the timer, at the
second impulse, if it is given before the end of the time, the timer
stops (if the output was actived now will be disabled), otherwise, if it
is given after the end of the time, the second pulse actives a new
counting cycle.
E = 2, t = 2 - RESET/START/STOP:
At the first pulse on CNT EN input the timer is resetted, at the
second the counting starts, at the third pulse the counting is
stopping, and so on.
E = 3 - MONOSTABLE START/STOP:
After being reset by means of the RESET input, the timer starts
when the CNT EN contact is closed and stops when the contact is
opened.
At this point, if the contact is closed again, the timer will re-start from
the current value, and so on until a RESET signal is transmitted or
the set time period has expired.
In this functioning mode the U frontal key works only as reset.

DOWN mode, ie. whether the display must show the time which has
passed or the remaining time. The options are:
1 = UP mode
2 = DOWN mode
b - BACK-UP MODE. This parameter determines the instrument
reaction in the case of power failure. The options are:
1 = Timer stops and memorized the counting current value
2 = Timer goes on counting (only with internal battery present and
enabled)
3 = Timer reset the counting
When option 1 has been chosed, the instrument goes off and the
counting current value is saved. When the power supply is restored,
the timer can will start working from the saved value.
When option 2 has been chosed, in the case of power failure the
display and the output will go off, but the timer will continue to count.
Note that the mode 2 is enabled only if the internal battery is present
and activated by the connection of relative terminal blocks (see
electrical connections).
Under these conditions of operation the display results turned on but
with an inferior brightness to the normal mode
We recommends to disable the battery when it is not necessary.
In case 3 finally, at the missing of power supply, the instrument
stops the counting and does not memorize the reached value, so
that at the returning of power supply the instrument will be in the
reset conditions.
