2 - PROGRAMMING
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.
2.2 – PARAMETERS PROGRAMMING
To have access at the functioning parameters, it’s necessary to
push key P and keep it pushed for 5 sec. approx.
After 4 sec. will appear the label of the first parameter ("F1").
Now it possible to release key P and it will appear the value
programmed for parameter "F1".
To modify this value work on keys UP or DOWN.
Once the desired value has been programmed, pushing again key
P the display will show the label of the successive parameter.
Releasing then key P, it will appear the value programmed for that
parameter which can be modified working on keys UP and DOWN.
Pushing and releasing key P it’s possible to visualize all the
parameters labels (when key is pushed) and the relative
programming (when key is released) one after the other.
The outgoing from the parameters programming it’s obtainable not
working on any key for 20 sec. approx. or pressing only one time
the key U, thus the counting value willl again be displayed.
P.A.: During the counting is not possible to enter in the parameters
programming mode.
2.3 – PARAMETERS LOCK
It’s possible to lock the access at the programming parameters with
the following procedure :
Switch off the instrument, push key P and keep it pushed while the
instrument is switched on again.
After approx. 5 sec. on the display will appear "uL" (unlock) which
indicates that the parameters are accessible.
Keeping pushed key P and pushing key DOWN it will appear "Lo"
(lock) which indicates that the parameters are not accessible.
Release key P to exit from this modality.
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
parameters lock modality.
3 - INSTALLATION AND USE ADVICES
3.1 – USE ALLOWED
The instrument has been projected as measure and
control device, built according to EN61010-1 for the
altitudes operation until 2000 ms.
The use of the instrument for applications not
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 case 33 x 75 mm, is designed for flush-in panel
mounting.
Make a hole 29 x 71 mm and insert the instrument, fixing it with the
provided special bracket.
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 connect the
external battery .
With the purpose to prolong its duration it recommends him to
disconnect the battery when it is not necessary to the operation.
Finally, it is advisable to check that the parameters are those
desired before connecting the outputs to the actuators in order to
avoid plant anomalies which may cause injuries to people, things or
animals.
Tecnologic S.p.A. and its legal representatives are not
responsible for any eventual damages to people, things or
animals deriving from the instrument violation, not proper or
wrong use or in any case not in accordance with the
instrument features.

4 - OPERATING MODE
4.1 – FUNCTIONING OF THE COUNTING COMMANDS
The counting can be enabled and disabled through the frontal key
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).
When the instrument is predisposed for the continuation of the
counting also without power supply, during the counting under
conditions of lack of supply the only active command is the RESET
one, which can be given only from the frontal key U.
When the instrument is supplied through the battery it is not
therefore possible to make the counting start again once stopped.
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).
4.3 - OUT1 OPERATING MODE
The instrument can be programmed by the parameter "F1" to
operate in any of the following 5 modes:
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.

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.
TECNOLOGIC spa - TT 34 - OPERATING INSTRUCTIONS - Vr. 01 - ISTR 06086 - PAG. 4

This procedure goes on until a RESET signal is transmitted or the

operating mode of the output OUT 1 as regards counting.
The 5 mode are:
1 = Delayed
2 = Feedthrough
3 = Asymmetrical Oscillator Start On
4 = Asymmetrical Oscillator Start Off
5 = One cycle Asymmetrical Oscillator Start Off
F 2 - OUT 2 OPERATING MODE: Permits the user to select the
operating mode of the output OUT 2 as regards counting.
The 5 mode are:
0 = Ouput disable
1 = Operating like OUT1
2 = On during counting
3 = Same function of OUT1 with time t3 absolute
4 = Same function of OUT1 with time t3 dependent from time t1
S1 - TIME RANGE t1 (and t3) : This parameter allows the user to
select the full range of the time t1 (and t3 if activate) according to
the following options:
1 = hrs (9999)
2 = hrs - min. (99 hrs 59 min.)
3 = min. - sec. (99 min. 59 sec. )
4 = sec. - cents (99 sec. 99 cents) .
S2 -TIME RANGE t2: This parameter only involves the operating
modes "F1"= 3 and 4, and is used to select the full range of the t2
time period. The options are the same as for the "S1" parameter.
H1 - HIGH SET POINT TIME t1 : This parameter allows the user to
program the 2 most significative figures of the Higher value
programmable as Set Point “t1”
H2 - HIGH SET POINT TIME t2: Similar to “H1” but referred to the
set “t2”.
C- COUNTING MODE. Permits the user to choose the UP or
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 external battery connected )
3 = Timer reset the counting
TECNOLOGIC spa - TT 34 - OPERATING INSTRUCTIONS - Vr. 01 - ISTR 06086 - PAG. 5

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 external battery
is present (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.
E- CNT EN INPUT OPERATING MODE. Allows the user to select
the operating mode of the Count Enable (CNT EN) external input.
The options are:
1 = Bistable Start/Stop
2 = Bistable Reset-Start/Stop
3 = Monostable Start/Stop
4 = Monostable Reset-Start/Stop
t - U KEY OPERATING MODE: This parameter permits to decide
the operating mode of the frontal U key and the possibilities are:
0 = Key disable
1 = RESET-START/STOP
2 = RESET/START/STOP
3 = RESETonly
