BUTTONS AND MENUS ACCESSING
AND USING MENUS

The resources are arranged in a menu that
can be accessed by pressing and quickly
releasing the “set” button (Machine Status
menu) or holding down the “set” button
for more than 5 seconds (Programming
menu).
To access the contents of each folder indi­cated by the relevant label, just press the
“set” button once.
You can now scroll through the contents
of each folder, modify it or use its func­tions. If you do not use the keyboard for
over 15 seconds (time-out) or if you press
the “fnc” button once, the last value
shown on the display is confirmed and you
are taken back to the previous screen
mask.

MACHINE STATUS MENU
(See Machine Status Menu Diagram)

To access the Machine Status menu, press
the “set” button and quickly release it.
The “SP1” label appears.
(If alarms are active, with the exception of
faulty probes/probe errors, the “AL” label
appears).
By using the “UP” and “DOWN” buttons
you can scroll through the other folders in
the menu: the folders are indicated below
in the order they appear:

-SP1: Set point 1 setting folder or

-AL: alarm folder (if alarms present, with
exception of faulty probes/probe errors);

-SP2: Set point 2 setting folder.

-Pb1: probe 1 value folder;

-Pb2: probe 2 value folder;

The folders are present according to
the presence and configuration of the
associated resource.

Alarm on

If an alarm condition exists when the
Machine Status menu is accessed, the “AL”
folder label appears (see “Diagnostics”
section).

USER INTERFACE

The user has a display and four buttons
for controlling instrument status and pro­gramming.

*FNC FUNCTION FOLDER
The FnC folder (last folder visible from
the Programming Menu, level 1) con­tains the following functions. They are
activated using the “set” button

If the unit is switched off, the function
labels go back to their default status.

SOFT START
Note: The SOFT START function is but­ton, D.I. or function selectable.

The Soft Start controller can be used to
set the temperature gradient required to
reach a specific set point in a specific peri­od of time.
This function automatically gives you a
progressive increase of the control set
point from the Ta value (ambient tempera­ture at start-up) to the value actually dis­played. This means that a rise in tempera­ture can be immediately stopped and the
risk of overshooting reduced. (continued

USING COPY CARD

The Copy Card is an accessory connect­ed to the TTL serial port used for quick
programming of the unit parameters
(upload and download parameter map
to one or more units of the same type).
Operations are described below:

Fr-Format

This command is used to format the
copy card. This is necessary if:

•it is used for the first time,

•it is used with models that are incom­patible,

•after use with a specific model if
another model needs to be connected.
Warning: when the copy card has been
programmed using the “Fr” parameter
all the data entered is cancelled. This
operation cannot be undone.

UL-Upload

This operation uploads the programming
parameters from the instrument.

dL-Download

This operation downloads the program­ming parameters to the instrument.

NOTE:

• UPLOAD: instrument —> Copy Card

• DOWNLOAD: Copy Card —> instru­ment.

The operations are performed by access­ing the folder identified by the “FPr”
label and selecting the “UL”, “dL” or “Fr”
commands. The operation is confirmed
by pressing the “set” button. If the oper­ation is successful, a “y” is displayed
whereas if it is unsuccessful an “n” will
be displayed.

Download “from reset”

Connect the copy card with the instru

­ment OFF. When the instrument is
switched on the programming parame­ters will be downloaded into the copy
card; when the lamp test has been com­pleted, the following appear on the dis­play for about 5 seconds:

• label dLY if copy operation is success­ful

• label DLn if operation fails
PLEASE NOTE:

• after downloading the instrument will
work with the parameter map settings
that have just been downloaded.

HOW TO LOCK THE KEYBOARD

Keyboard operating can be locked by pro­gramming the “LOC” parameter (see folder
with “diS” table).
If the keyboard is locked you can only
access the Programming MENU (see)
Functions CANNOT be activated with but­tons (to silence alarms, for example) .

HOW TO SET THE SET POINTS
Setting Setpoint 1 (Setpoint 2)

Go to the “Machine Status” menu, press the “set” button and quickly release it. The “SP1” folder label appears.
(To set Set point 2 press the “UP“ and “DOWN“ buttons until “SP2” appears). To display the Set point 1 (2) value, press the “set” but­ton again.
The Set point value appears on the display. To change the Set point 1 (2) value, press the “UP” and “DOWN” buttons within 15 seconds.
If parameter LOC = y the Set points cannot be changed.

HOW TO DISPLAY THE TEMPERATURE READ BY PROBE(S)

If you press the “set” button when the corresponding label appears, the value of the probe associated with it is displayed.

ALARM PRESENT?

If an alarm condition exists when the Machine Status menu is accessed, the “AL” folder label appears. which will include the alarm
codes. (see section on “Diagnostics”).

PROGRAMMING MENU
(See Programming Menu Diagram)

1) Displaying level 1 parameters

To access the Programming menu, hold
the “set” button for more than 5 seconds.

Level 1 parameters can be protected by a
PASSWORD* (defined by parameter
DIS/PA1) If the PASSWORD is enabled,
the label “PA1” will appear when you
access the Programming Menu; press
the “set” button and the value “0” will
appear; enter the password using the
“UP”/”DOWN” buttons and press the
“set” button again. This allows you to
access the level 1 parameters.
The first folder that appears is “CP”.
Use the “UP” and “DOWN” buttons to
scroll through the other folders; the

folders will only display level 1 para­meters.
NOTE: at this point level 2 parameters
are NOT visible even if NOT password­protected.

2) Displaying level 2 parameters

Go to the “CnF” folder in the
Programming Menu and scroll down the
parameters until you reach the PA2 label.
By pressing and releasing the “set” but­ton you will enter the level 2 parameters
and the “CP” label of the first folder in

the programming menu will appear.

The level 2 parameters can be protected
by a second PASSWORD* (defined by
parameter DIS/PA2)
(NOTE: not to be confused with the PA2
label in the “CnF” folder).
If the PASSWORD is enabled, the label
“PA2” will appear in CnF/PA2 when you
access the Programming Menu; press
the “set” button and the value “0” will
appear; enter the password using the
“UP”/”DOWN” buttons and press the
“set” button again. This allows you to
access the level 2 parameters. The first
folder that appears is “CP”.

NOTE: At this level the folders will
only display all the level 2 parame­ters.Therefore level 1 parameters will

only be visible if you quit the
Programming Menu and repeat proce­dure 1).

NOTE: It is strongly recommended that
the unit is switched off and on again
each time parameter configuration is
changed in order to prevent malfunc­tioning of the configuration and/or
ongoing timings (compulsory for selec-

tion of probe type and count parame­ters).

*PASSWORD

Passwords “PA1” and “PA2” allow level 1
and level 2 parameters to be accessed.
There are no passwords in the standard
configuration. To enable them (value ≠0)
and assign them the desired value, access
the Programming menu in the “diS” fold­er. If passwords are enabled, they will be
requested:

- PA1 when entering the Programming
menu (see the “Programming Menu“ sec­tion);

- PA2 in the “Cnf” folder containing the
level 1 parameters.
