1 - INSTRUMENT DESCRIPTION
1 .1 - GENERAL DESCRIPTION
The models TLB 30 (Display and control unit) and BSLB4 (Supply
and outputs unit) are a digital controller system with
microprocessor that is typically used in cooling applications that
have temperature control with ON/OFF regulation and defrosting
control with set time by means of electrical heating or hot
gas/reverse cycle.
The system has up to 4 relay outputs, 2 inputs for PTC or NTC
temperature probes and 2 digital inputs, that can all be configured.
The 4 outputs at main voltage (in BSL unit) can be used for
controlling the compressor or the temperature control device, the
defrosting device, the evaporation fan and an alarm or an auxiliary
device (light, second compressor etc.) .
The two inputs for the PTC and NTC temperature probes (which
can be selected by parameter) connected to TLB30 unit can be
used to measure the cell temperature (Pr1) and the evaporator
temperature (Pr2) while the digital inputs (DIG1,2) can be
programmed to carry out various functions such as defrosting
commands, selecting 2 or 4 different set of temperature
regulations, external alarm signals, activating a continuous cycle,
and activating an auxiliary output etc.
ASCON TECNOLOGIC - TLB30 - OPERATING INSTRUCTIONS - Vr. 04 - 02/12 - ISTR-MTLB30ENG04 - PAG. 1
Furthermore, the instrument allows an optional voltage alarm to
disable control outputs when main voltage is too low or too high.
The instrument is equipped with a big 2-digit display (h 31 mm )
with - indication and 3 LED signals.
The parameters programming is possible by a remote keyboard
(TLBTA) in standard model or by capacitive sensor keyboard (Stouch) in S version while the connection between the units TLB30
and BSLB4 it happens through a cable with RJ connectors
(TLBCA).

2 - PROGRAMMING
2.1 - PROGRAMMING OF THE SET POINT
Press the key P then release it and the display will show SP (or S2,
S3, S4 if a different set is active at that time) alternating with the set
value (see selection of the active set point).
To change it press the UP key to increase the value or DOWN to
decrease it.
These keys increase or decrease the value one digit at a time, but
if the button is pressed for more than one second the value
increase or decreases rapidly, and after two seconds pressed, the
speed increases even more to all the desired valued to be reached
rapidly.
Exiting the Set mode is achieved by pressing the P key or
automatically if no key is pressed for 15 seconds. After that time
the display returns to the normal function mode.
2.2 - PARAMETERS PROGRAMMING
To access the instrument’s function parameters, press the key P
and keep it pressed for about 5 seconds, after which the SET led
will light up, the display will visualised the code that identifies the
first group of parameters (“-SP “) and the group of parameters that
are to be edited are selected by pressing the UP and DOWN keys.
Once the group of parameters has been selected, press the P and
the code that identifies the first parameter in the selected group will
be visualised.
Again using the UP and DOWN keys, the desired parameter can
be selected and pressing the P key, the display will alternately
show the parameter code and its setting that can be changed with
the UP and DOWN keys.
Once the desired value has been set, press the key P again: the
new value will be memorised and the display will show only the
abbreviation of the selected parameter.
Pressing the UP and DOWN keys, it is possible to select another
parameter (if present) and change it as described.
To return to select another group of parameters, keep the U key
pressed for about 1 second, after which the display will return to
showing the code of the parameter group.
Release the pressed key and using the UP and DOWN keys it will
be possible to select another group (if present).
To exit the programming mode, do not press any key for about 20
seconds, or keep the U key pressed until it exits the programming
mode.

2.3 - PARAMETER PROTECTION USING THE PASSWORD
The instrument has a parameter protection function using a
password that can be personalised, through the “PP” parameter in
the “-Pn” set.
If one wishes to have this protection, set the password number
desired in the parameter “PP”.
When the protection is working, press the P key to access the
parameters and keep it press for about 5 seconds, after which the
LED SET will flash and the display will show “0” .
At this point, using the UP and DOWN keys, set the password
number programmed and press the key "P".
If the password is correct, the display will visualise the code that
identifies the first group of parameters(“-SP “) and it will be possible
to programme the instrument in the same ways described in the
previous section.
Protection using a password can be disabled by setting the
parameter “PP” = oF.
2.4 - PARAMETERS PROGRAMMING LEVELS
The instrument has two parameter programming levels.
The first level (“visible” parameters) is accessed according to the
procedure described above (with or without password request)
while the second level (“hidden” password) can be accessed
according to the following procedure.
Remove the power supply to the instrument, press the key P and
return power to the instrument, keeping the key pressed.
After about 5 sec. the SET led will light up, the display will show the
code that identifies the first group of parameters(“-SP “) and it will
be possible to set the parameters of the instrument using the same
programming procedure described previously.
Once the parameter has been selected and the SET is on, it means
that the parameter can be programmed even on the first level
("visible”).
If the led SET is off it means that the parameter can only be
programmed on this level (i.e. “hidden”).
To change the visibility of the parameter, press the key U: the led
SET will change status, indicating the accessibility level of the
parameter (on = parameter “visible”; off = parameter “hidden”).

4 - FUNCTIONS
ASCON TECNOLOGIC - TLB30 - OPERATING INSTRUCTIONS - Vr. 04 - 02/12 - ISTR-MTLB30ENG04 - PAG. 4
This function foresees a time control on the switching on of the “Ot”
output associated with the temperature regulation request.
The protection consists of preventing the output being switched on
during the time set in the parameter “Pt” and counted depending
on what has been programmed in the parameter “PS”, and
therefore that any activation occurs only after the “Pt” time has
finished.
If during the power on delay phase, the regulator request should
disappear, due to an inhibition caused by the compressor
protection function, the foreseen start up of the output is naturally
cancelled.
Using the parameter "PS", it is possible to set the type of
compressor protection and therefore from when the inhibition time
“Pt” must start.
The parameter “PS” can be set as:

= cS - the instrument carries out a defrosting cycle at each
compressor stop (i.e. at each deactivation of the output Ot). If this
option is used, set “di”=oF.
The automatic defrosting cycle can be at time intervals or, if an
evaporator probe is used (Pr2), when a temperature is reached.
If the evaporator probe is not used (par. “EP” = oF) the duration
cycle is set by the parameter “dE”.
If instead the evaporator probe is used (parameter “EP” = on) the
defrosting takes place when the temperature measured by the
probe exceeds the temperature set in the parameter “tE”.
If this temperature is not reached in the time set in the parameter
“dE”, defrosting is interrupted.
In order to avoid pointless defrosting the parameter. “tS” is
foreseen that sets the enablement temperature for defrosting
If the temperature measured by the probe is higher than the one

The function is disabled by “od” = oF.
During the power on delay phase, the display shows the indication
od, alternating with the normal programmed visualisation.
4.6 - DEFROST CONTROL
All the parameters concerning the defrosting control that acts on
the outputs configured as “Ot” and “dF”, are container in the group
“-dF”.
The type of defrosting that the instrument must carry out is set by
the parameter “dt” that can be programmed:
= EL - WITH ELECTRICAL HEATING
or BY STOPPING
COMPRESSOR (during defrosting, the output “Ot” is deactivated
while the output “dF” is enabled)
= in - WITH HOT GAS or INVERSION OF CYCLE (during
defrosting the outputs “Ot” and “dF” are enabled)
The automatic defrosting can take place at intervals.
Defrosting at intervals is possible by setting the time that runs
between the two next automatic defrostings in the parameter “di”.
Counting this interval is set through the parameter "dC" that can
be programmed:
= rt - counts the total function time (instrument on)

Examples: defrosting 1 ends due to reaching of temperature “tE”,
defrosting 2 ends at the end of the “dE” time as the temperature
“tE” is not reached, defrosting 3 does not take place as the
temperature is higher than “tS”.
At the end of defrosting, it is possible to delay the new start up of
the compressor (output “Ot”) at the time set in parameter “td” to
allow the evaporator to drain.
During this delay, the led Def flashes to indicate the draining state.
If one wishes to set a defrosting cycle every time the instrument is
switched on (as long as the conditions set in the parameters “tS”
and "tE" apply) programme the parameter “Sd” = y.
This allows the evaporator to be permanently defrosted, even when
frequent interruptions to power supply occur that may cause the
cancellation of the various defrosting cycles.
During the defrosting, it may occur that the temperature measured
by the cell probe (Pr1) increases excessively (this obviously
depends on the position of the probe Pr1 compared to the
evaporator).
In the event that one does not wish this increase to be visualised
by the instrument, it is possible to use the functions in the
parameter “dL” (Block display during defrosting) and “Et”
(Differential unblocking of display after defrosting).
The parameter “dL” = on allows the temperature Pr1 visualisation
to be blocked on the last reading during a whole defrosting cycle
and until the temperature does not return under the value [”SP” +
“d”] after defrosting has finished (or the time set in the parameter
"dA" contained in the block “-AL”).
With “dL” = Lb, this allows visualisation of the writing dF during
defrosting and at the end of defrosting the writing Pd up to when
the temperature Pr1 does not return below the value [”SP” + “d”] (or
the time set on the parameter "dA" contained in the block “-AL”).
Alternatively with the “dL” = oF, during defrosting, the instrument
will continue to visualise the temperature measured by the probe

4.9 - ALARM FUNCTIONS
All the parameters concerning the alarm functions are contained in
group “-AL”.
The alarm functions of the instrument work on the output desired, if
configured by the parameters “o1”, “o2”, “o3”, “o4” depending on
what is set on the said parameters.
The possible selections of these parameters for the alarm
signalling function are:
= At - when one wants the output to be activated in alarm and can
be disabled (alarm silencing) manually by pressing any key of the
instrument (typical application for sound signal).
= AL - when one wants the output to be activated in alarm status
but cannot be disabled manually and are therefore only disabled
when the alarm status ceases (typical application for a light signal).
= An - when one wants the output to be activated in alarm status
and that they remain activated even when the alarm has ceased
(see par.4.9.5) Disablement (recognition of memorised alarm) can
only be carried out manually by pressing any key when the alarm
has ended (typical application for light signal).
= -At - when one wants the function described as At but with an
inverse function (output activated in normal condition and disabled
in alarm status).

4.9.2 - EXTERNAL ALARM
The instrument can signal an external alarm by activating the digital
input 1 with the function programmed as “Fi” = 4 or 9 (see par.
4.10).
At the same time as the signalling of the configured alarm output,
the instrument visualising AL and the variable set in parameter
“dS” alternately on the display.
4.9.3 - OPEN DOOR ALARM
The instrument can signal an open door alarm by activating the
digital input 1 with the function programmed as “Fi” = 5 or 6 (see
par. 4.10).
When the digital input is activated and after the delay programmed
in parameter “oA”, the instrument signals the alarm via the
activation of the configured alarm output, and oP and the variable
set in parameter “dS” are visualised alternately on the display.
4.9.4 - MAIN VOLTAGE ALARMS
All the parameters concerning the voltage alarm functions are
contained in group “-Pr”.
If the instrument is equipped with voltage alarms function it is
possible to disable the control outputs when the main voltage is
lower or higher than the values sets to the parameters:
"LU" - Low voltage Alarm (expressed in V x 10)
"HU" - High voltage Alarm (expressed in V x 10)
The temperature alarm is enabled at the end of exclusion time and
is enabled after the “At” time when the temperature measured by
the probe Pr1 exceeds or goes below the respective maximum and
minimum alarm thresholds.
At the intervention of the alarm (and after the “Ud” time) all the
control outputs are disabled, the alarm is activated and the
instrument visualises UL and the variable set in parameter “dS”
alternately on the display.
ASCON TECNOLOGIC - TLB30 - OPERATING INSTRUCTIONS - Vr. 04 - 02/12 - ISTR-MTLB30ENG04 - PAG. 7
4.12 - FUNCTIONING OF KEYS “U” AND “DOWN/AUX”
Two of the instrument keys, in addition to their normal functions,
can be configured to operate other commands.
The U key function can be defined by the parameter “UF” while the
DOWN/AUX key function can be defined by the parameter “Fb”
both contained in the group “-Pn”.
Both the parameters have the same possibilities and can be
configured for the following functions:
= 0 - The key carries out no function.
= 1 - Pressing the key for at least 1 second, it is possible to
enable/disable the auxiliary output if configured (“FO”=2).
= 2 - Pressing the key for at least 1 second, it is possible to
enable/disable a continuous cycle (see continuous cycle function).
= 3 - Pressing the key for at least 1 second, it is possible to switch
between SP and S2 memorised set point in rotation. Once
selection has been made, the display will flash the active set point
code for about 1 sec. (SP, S2).
= 4 - Pressing the key for at least 1 second, it is possible to switch
the instrument from the ON status to Stand-by status and vice
versa.
4.13 - PARAMETERS CONFIGURATION BY “A01”
The instrument is equipped with a connector that allows the transfer from and toward the instrument of the functioning parameters
through the device A01 with 5 poles connector.
This device A01 it’s mainly useable for the serial programming of
the instruments which need to have the same parameters
configuration or to keep a copy of the programming of an
instrument and allow its rapid retransmission.
The same device can connect the instrument via USB to a PC and
through the proper configuration software tools "TECNOLOGIC
UniversalConf”, it’s possible to configure the operating parameters.
To use the device A01 it’s necessary that the device or instrument
