"tunE"
: it permits to activate the Autotuning or Selftuning function and
appears only if the parameter "Auto" is different from "no" or if the
parameter "SELF" is "yES".
"OFF"
: permits to switch the instrument into "OFF" state
" OPLO"
: permits to switch the instrument into manual control state and
then to program the % control value to apply. Appears only if par.
"EnOL" is programmes as "yES". Once selected the desired parameter
push "P" key to confirm it.
The selections "OPEr", "ConF" and "SPn" give
access to minor menu containing other parameters or options and more
precisely :
"OPEr"
: Operative parameters menu
:
contains the Set point parameters
and the alarms parameters
"ConF"
: Configuration parameters menu
:
contains the functioning
configuration parameters ( Alarms and input configuration, etc.)
"SPn"
: Selection menu of the active Set point
:
contains the selections of
the possible Set point to define as active.
Inside of these menu, on the upper display appears the parameter name
selected, while on the lower display appears its actual value.
The keys have then the following functions :
"LEFT"
: used to shift the "cursor" (flashing) on the figure that is desired
to modify
"UP"
: used to increase the figure on which is placed the "cursor". In
case of parameters not numerical, "UP" key is needed to select the
available options
"P"
: used to confirm the programmed data and pass then to the next
parameter. Keeping pushed "P" key and pushing "UP" key, the parameters
run over backwards. To accede to "ConF" menu it's requested a
PASSWORD. Set, using "UP" and "LEFT" keys, the number written on the
last page of this instruction manual and push then "P" key. If the password
entered is wrong, the instrument go back to the previous control state.
P.A. :
Always go regularly out from the programming phase because, if the
instrument is switched off during the programming, at the next start-up
could
be signalled the memory error "Err EEPr", To re-establish the
functioning occurs then to push "LEFT" key.
6 - PARAMETERS
DESCRIPTION
Here following are described all the instrument parameters; pls. note that
some of them could do not appear or because are according to the kind of
used instrument or because are automatically not qualified, as they're not
necessary.

SEt2
- SET POINT 2: Control value of Set Point n.2
SEt3
- SET POINT 3: Control value of Set Point n.3
SEt4
- SET POINT 4: Control value of Set Point n.4
ALHb
- HEATER BREAK ALARM THRESHOLD :
Activation set of
Heater Break alarm.
AL3
- ALARM A3 THRESHOLD : A3 alarm threshold for minimum or
maximum alarms.
AL3L
- MINIMUM ALARM A3 THRESHOLD : A3 alarm threshold
working as minimum alarm when it's set a window alarm type.
AL3H
- MAXIMUM ALARM A3 THRESHOLD : A1 alarm threshold
working as maximum alarm when it's set a window alarm type .
AL4
- ALARM A4 THRESHOLD : Equal to "AL3", but referred to A4
alarm.
AL4L
- MINIMUM ALARM A4 THRESHOLD : Equal to "AL3L", but
referred to A4 alarm.
AL4H
- MAXIMUM ALARM A4 THRESHOLD : Equal to "AL3H", but
referred to A4 alarm.
- "ConF" MENU
HSEt
- SET POINT HYSTERESIS : Semi-band relative to the Set Point,
which decides the C1 outputs activation and deactivation values when the
control mode is ON/OFF.
HAL3
- ALARM A3 HYSTERESIS : Asymmetric semi-band referred to A3
alarm value, that establish the deactivation value of A3 alarm.
HAL4
- ALARM A4 HYSTERESIS : Equal to "HAL3", but referred to A4
alarm.
FAL3
- A3/HB OUTPUT FUNCTIONING MODE : Permits to establish if
A3/HB output has to operate as alarm ("AL3") or Heater Break alarm
("Hb").
AL3t
- A3 ALARM TYPE : Permit to establish the type of A3 alarm (see
alarm output functioning mode)
AL3c
- CONFIGURATION OF A3 ALARM FUNCTIONING MODE :
Permit to establish the functioning mode of A3 alarm (see alarm output
functioning mode)
AL3o
- A3 ALARM BEHAVIOUR IN OFF CONTROL MODE : Permit to
establish if in "OFF" control mode the alarm has to be active ("On") or not
active ("OFF")
AL4t
- A4 ALARM TYPE : Equal to "AL3t", but referred to A4 alarm.
AL4c
- CONFIGURATION OF A4 ALARM FUNCTIONING MODE :
Equal to "AL3c", but referred to A4 alarm.
AL4o
- A4 ALARM BEHAVIOUR IN OFF CONTROL MODE :
Equal to
"AL3o", but referred to A4 alarm.
rLHb
- OUTPUT HB LOGIC MODE : Permits to establish the Heater
Break alarm (A3/HB) functioning mode, setting the output rest state ("nO"
= normally deactivated, "nC" = normally activated)
LbAP -
LOOP BREAK ALARM POWER : Value of C1 output power (in
%); if it is exceeded, intervene the time counting programmed on par.
"LbAt" that active the Loop Break alarm.
AbAt -
LOOP BREAK ALARM MAX. TIME : Maximum time that the power
programmed on par. "LbAP" can be applicable on the load (in sec.) before
that Loop Break alarm intervene
ALPr
- ALARMS PROGRAMMING ON "CONF" MENU : Permits to make
visible the alarm setting parameters on "OPEr" menu ("no") or on "ConF"
menu ("yES").
SPLL
- LOW/MINIMUM SET POINT : Minimum possible Set Point value
or lower limit of Set point.
SPHL
- HIGH/MAXIMUM SET POINT : Maximum possible Set Point
value or higher limit of Set point.
Cont
- CONTROL MODE : Permits to select one of the possible control
mode offered by the instrument : ON/OFF with symmetric hysteresis
("OnFS"), ON/OFF with asymmetric hysteresis ("OnFa") or PID ("Pid").
Func -
OUTPUT C1 OPERATING MODE : Permits to decide if C1
control mode has to act a reverse action, as an Heating process ("HEAt")
or a direct action, as a Cooling process ("CooL"). If it's desired to use the
PID control mode for motorised actuators, program the parameter as
"HEAt".
C2 -
C2/A4 OUTPUT FUNCTIONING MODE : Permits to establish if
C2/A4 output has to operate as alarm ("AL4") or as C2 output fot
motorised actuators ("3Pt").
SELF
- SELFTUNING: Parameter to enable (yES) or disable (no) of the

the option "tunE" , that permits to carry on the Autotuning cycle to
automatically tune the right PID regulation parameters. It's possible to

the effective value of the Set Point ("SP") or to a reduced value equal to
