1. Installation and use warnings
Permitted use
- The instrument has been projected and manufactured as
a measuring and control device to be used according to EN61010-1 for the
altitudes operation until 2000 ms. The use of the instrument for applications not
expressly permitted by the above mentioned rule must adopt all the necessary
protective measures.
The instrument CANNOT be used in dangerous environments (flammable or explo-
sive) without adequate protection. The installer must ensure that EMC rules are
respected, also after the instrument installation, if necessary using proper filters.
Mechanical mounting
TLK48 B -The instrument, in case 48 x 48 mm, is designed for flush-in panel
mounting. Make 45 x 45 mm a hole and insert the instrument, fixing it with the
provided special brackets. We recommend that the gasket is mounted in order
to obtain the declared front protection degree.

General installation warnings -
Avoid placing the instrument in environ-
ments with very high humidity levels or dirt that may create condensation or intro-
duction of conductive substances into the instrument. Ensure adequate ventilation
to the instrument and avoid installation in containers that house devices which may
overheat or which may cause the instrument to function at a higher temperature
than the one permitted and declared.
Connect the instrument as far away as possible from sources of electromagnetic
disturbances such as motors, power relays, relays, solenoid valves, etc..
Electrical connections - Carry out the electrical wiring by connecting only one
wire to each terminal, according to the following diagram, checking that the power
supply is the same as that indicated on the instrument and that the load current
absorption is no higher than the maximum electricity current permitted.

As the instrument is built-in equipment with permanent connection inside
housing, it is not equipped with either switches or internal devices to protect
against overload of current: the installation will include an overload protection
and a two-phase circuit-breaker, placed as near as possible to the instrument
and located in a position that can easily be reached by the user and marked
as instrument disconnecting device which interrupts the power supply to the
equipment. It is also recommended that the supply of all the electrical circuits
connected to the instrument must be protect properly, using devices (ex. fuses)
proportionate to the circulating currents.
It is strongly recommended that cables with proper insulation, according to the
working voltages and temperatures, be used. 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 to the ground with only one side. We
recommend that a check should be made that the parameters are those desired
and that the application functions correctly before connecting the outputs to the
actuators so as to avoid malfunctioning that may cause irregularities in the plant
that could cause damage to people, things or animals.
2. Instrument description
TLK48 B and TLK72 B are digital microprocessor-based controllers, with ON/OFF,
Neutral Zone ON/OFF, PID single action, PID dual action (direct and reverse)
control and with
AUTOTUNING
function (FAST or OSCILLATING type).
The instrument can have up to 2 outputs: relay type or can drive solid state relays
type (SSR). Depending on the model required the input accept:
C: Thermocouples temperature probes (J, K, S and ZIS Infrared sensors),
mV signals (0... 50/60 mV, 12... 60 mV) and Pt100 thermoresistances;
E: Thermocouples temperature probes (J, K, S and ZIS Infrared sensors),
mV signals (0... 50/60 mV, 12... 60 mV) and PTC or NTC Thermistors;
I: Normalized analogue signals 0/4... 20 mA;
V: Normalized analogue signals 0... 1 V, 0/1... 5 V, 0/2... 10 V.

3. Controller Programming
Set Point Quick Setup -This procedure allows the fast programming of the
active Set Point (SP1) and eventually the alarm threshold (AL1). Push key , then
release it, the display shows SP1 and its programmed value; to modify it, press
to increase the value or key to decrease it. These keys change the value one
digit at a time, but if they are pressed for more than one second, the value increases
or decreases rapidly, then, after two seconds in the same condition, the changing
speed further increases in order to rapidly reach the desired value. Once the desired
value has been reached, pushing key it is possible to exit the Quick Setup mode
or (if the instrument have an output configured as alarm) is possible to display
and modify the alarm threshold in sthe same way as SP1. To exit the Set Point
Quick Setup it is necessary to press after the visualisation of the last Set Point,
or alternatively pressing no keys for about 15 seconds the display automatically
returns to normal functioning. Set Point SP1 can be programmed with a value that
is between the value programmed between the parameters SPLL and SPHL.
Parameters programming - By pushing key
and holding it down for
about 2 s it is possible to enter into the main selection menu. Using the
or
keys, it is then possible to roll over the selections:
OPEr
Operating parameters Menu
: this normally contains the Set Point “SP1”
and the alarm threshold “AL1” parameters but it can contain all the
desired parameters (see par. 2.3).
ConF
Configuration parameters Menu
: this contains all the operating param-
eters and the functioning configuration parameters.

To enter the ConF menu select the option ConF, press the key , the display
shows 0. At this request, enter, using keys and , the number reported
on the last page of this manual and push key . If an incorrect password
is entered, the instrument exit from programming mode. If the password is
correct, the display shows the code that identifies the first group of parameters
(]SP) and with keys and it will be possible to select the desired group of
parameters. Once the desired group of parameters has been selected, the code
identifying the first parameter of the selected group will be visualised by pushing
the key. Again using the and keys, it is possible to select the desired
parameter and, if the key is pressed, the display will alternatively show the
parameter code and its programming value, which can be modified by using the
/ keys. Once the desired value has been programmed, push key once
more: the new value will be memorised and the display will show only the code
of the selected parameter. By using the / keys, it is then possible to select
a new parameter (if present) and modify it as described above.
To select another group of parameters, keep the
/ key pressed for about 2
s, afterwards the display will return to visualise the code of the group of param-
eters. Release the key and by using the
and keys, it will be possible to
select a new group . To exit the programming mode, no key should be pressed
for about 20 s, or keep the
/ pressed until exit from the programming
mode is obtained. The programming and exit modes for the OPEr menu are the
same as those described for menu ConF with the difference that to access the
menu OPEr the Password is not required.
The instrument is factory programmed with all the parameters, with
the exception of SP1 Set Point and AL1 alarm threshold, programma-
ble in the menu ConF. This has be done with the purpose to prevent
wrong accidental programming from non experienced consumers.
4. Programmable parameters
Below are described all the parameters available in the instrument. Some
of them could be not present either because they are instrument depend or
because they are automatically disabled as unnecessary.
