Ft

 - CONTROL MODE: Allows the selection of one of possible control

modes that the instrument offers: ON/OFF (on), PID (Pi) or Neutral Zone
(nr).

PSE

 - INPUT PROBE: Allows selecting, if the instrument type is for

thermocouples or for thermoresistances, various types of probe: J (FE), K
(Cr), S (rh) for thermocouples and Pt100 (Pt), Ni100 (ni) for
thermoresistances. On changing this parameter it is to be remember that
the exit programming phase is to be carried out first afterwhich the
instrument is to be switched off and then on again.

OCO

 - SETS CONNECTION: Determines if the two Sets are to be

independent or if Set2 must be considered relative to Set1 (in=independent,
di=dependent).

HC1 

- OUTPUT 1 OPERATING MODE: Determines if the output OUT1 is

tocontrol a process which increment is intended as positive or reverse (ex.
Heating, Humidification etc.) or a process which increment is intended as
negative or direct (ex. Cooling, Dehumidification etc.) (H=reverse ,
C=direct).

HC2 

- OUTPUT 2 OPERATING MODE: Determines if the output OUT2 is

to control a process which increment is intended as positive or reverse (ex.
Heating, Humidification etc.) or a process which increment is intended as
negative or direct (ex. Cooling, Dehumidification etc.) (H=reverse ,
C=direct).

dP

 - DECIMAL POINT : Allows the insertion of the decimal point on the

display and therefore to determine resolution of the reading value (1 or
0,1) but not modified the Set, the Set limits (par. "LS", "HS") and the input
limits (par. "Lci", "Hci"). Example, if the Set was 20 the new Set will be 2.0
(on= with decimal point, oF=without decimal point).(available only for
models provided for PTC, RTD and normalized signals input). 

rou 

- UNIT OF MEASUREMENT: Determines the visualization of the

temperature in Centigrade or Fahrenheit degree. It is to be remember that
the change of this parameter modifies the visualization but not the Set and
the Set limit ("LS" and "HS") programmed (eg. if the Set was 50°C and the
unit changes, the Set will rest 50°F).

tun 

- AUTOTUNING: Determines the selection of Autotuning function for

the automatic setting of  PID parameters (n=no autotuning, y=start
autotuning).

hdd

 - HALF DIGIT DISPLAY: This parameter allows the approximation of

the last digit at right side. Infact when this parameter is in on mode, on this
digit will be show 0 when the real measuring value is between 0 and 4, and
will be show 5 when the real measuring value is between 5 and 9. For
example if the real measure is 78 display will show 75, or if the real
measure is 70.3 the display will show 70.0 (n=without approximation,
y=with approximation).

7 - PROBLEMS, MAINTENANCE AND WARRANTY
ERRORS SIGNALLING: 

The instrument shows the error message

"EEEE"

 , when  the probe is interrupted or in overrange, or 

"- - - -"

when the probe (PTC, RTD or normalised signals) is in short-circuit or
underrange; in this case verify the correct  probe wiring with the
instrument and afterward proceed to verify itself.  In the error condition all
the outputs are disactivated.

HOW TO CLEAN

We recommend  to avoid abrasive cleaners or  

containing solvents which could damage the instrument.

WARRANTY AND REPAIRS

The instrument is under warranty against

construction vices  or defected material, noticed within 12 months from
delivery date.The warranty is limited to the repairs or to the substitution of
the instrument. The eventual opening of the housing, the violation of the
instrument or the wrong use and installation of the product means the
automatically decay of the warranty. In case of defected instrument,
noticed in warranty period  or out of warranty, do contact our sales
department to obtain the shipment authorisation. The defected product
must be shipped to TECNOLOGIC with the detailed description of the
failures found  and without any fees or charge for Tecnologic, safe
different agreements.
