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 54 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 (

S-

touch

) in

 

S version while the connection between the units TLB55

and BSLB4 it happens through a cable with RJ connectors
(

TLBCA

).

1 - Key P

 : Used for setting the Set point and for programming the

function parameters

2 - Key DOWN/Aux

 : Used for decreasing the values to be set and

for selecting the parameters. It can also be programmed via the
parameter “Fb” to carry out other functions such as activating the
Aux output, starting up the continuous cycle, selecting the active
set point or turning on and off (stand-by) the device (see par. 4.12).

3 - Key UP/DEFROST

 : Used for increasing the value to be set, for

selecting the parameters and for activating manual defrosting.

4 - Key U : 

Used for visualising the temperatures taken by the cell

probes and evaporator (Pr1 and Pr2) and the internal clock (if
present). It can also be programmed via the parameter “UF” to
carry out other functions, just like the key DOWN/AUX (see par.
4.12).

5 - Led OUT 

: Indicates the compressor output status (or the

temperature control device) on (on), off (off) or inhibited (flashing)

6 - Led DEF :

 Indicates defrosting in progress (on) or dripping

(flashing)

.

7 - Led FAN :

 Indicates fan output status on (on), off (off) or

delayed after defrosting (flashing)

8 - Led SET 

: Indicates the input in programming mode and the

programming level of the parameters

9 - Led Stand-By:

 Indicate the Stand-by status.

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”).
