At start-up the instrument performs a
Lamp Test; for few seconds the display and
the leds blink, in order to verify their
integrity and correct operation. The instru-
ment has two main menus: the “Machine
Status” and “Programming” menu.
ACCESSING AND USING MENUS
Resources are arranged in a menu, which
can be accessed by pressing and quickly
releasing the “set” key (“Machine Status”
menu) or by holding down the “set” key
for more than 5 seconds (“Programming”
menu).
To access the contents of each folder, indi-
cated by the relevant label, just press the
“set” key once.
You can now scroll through the contents
of each folder, modify it or use its func-
tions.
If you do not use the keyboard for over
15 seconds (time-out) or if you press the
“fnc” key once, the last value shown on
the display is confirmed and you return to
the previous screen mask.
MACHINE STATUS MENU
To access the “Machine Status” menu
Press and quickly release the “set” key.
If alarms are not present, the label “SEt”
appears. By using the “UP” and “DOWN”
keys you can scroll through the other fold-
ers in the menu:
-AL: alarm folder (if present);
-Pb1: probe 1 value folder;
-SEt: Setpoint setting folder.
Set Setting
Access the “Machine Status” menu by
pressing and quickly releasing the “set”
key. The label of the “SEt” folder appears.
To display the Setpoint value press the
“set” key again.
The value appears on the display.
To change the Setpoint value, use the “UP”
and “DOWN” keys within 15 seconds.
If the parameter is LOC = y the Setpoint
cannot be changed.
Alarm on
If alarm condition exists, when accessing
The “Machine Status” menu the “AL” fold-
er label appears (see the “Diagnostics”
section).
Displaying Probes
By pressing the “set” key when the appro-
priate label appears, the value of the
probe associated to it is displayed.
PROGRAMMING MENU
1) Level 1 Parameters
To access the “Programming” menu, press
the “set” key for more than 5 seconds. If
specified, the level 1 access PASSWORD
will be requested (see parameter “PA1”)
and (if the password is correct) the label
of the first folder will follow. If the pass-
word is wrong, the display will show the
PA1 label again.
To scroll other folders, use the “UP” and
“DOWN” keys; the folders contain only
the level 1 parameters.
NOTE: At this point level 2 parameters
are NOT visible, even if they aren’t
protected by password.
2) Level 2 Parameters
In the Programming Menu go into the
“CnF” folder, scroll all the parameter until
you reach the PA2 label. By pressing and
releasing the “set” button you will enter to
level 2 parameters and the label of the
first folder in the programming menu will
follow.
The level 2 parameters may be protected
by a second password (see “PA2” parame-
ter inside “diS” folder, not to be confused
with PA2 label inside “CnF” folder.
If specified, level 2 parameters are hidden
to user; accessing the “CnF” folder the
level 2 access PASSWORD will be request-
ed and (if the correct password is entered)
the label of the first folder in the pro-
gramming menu will follow.
NOTE: At this point you will see only
level 2 parameters.
Level 1 parameters will NOT be visible;
to reach them you shall exit the
Programming Menu and re-entry the
Programming Menu section (see step 1).
To enter the folder, press “set”. The label
of the first visible parameter appears. To
scroll through the other parameters, use
the “UP” and “DOWN” keys; to change the
parameter, press and release “set”, then
set the desired value using the “UP” and
“DOWN” keys, and confirm with the “set”
key. Move to the next parameter.
PLEASE NOTE: It is suggested to switch-
off and switch-on again the instrument
everytime it is changed the configuration
of the parameters: this prevents malfunc-
tioning on regulation and delay time
occuring.
PASSWORD
The passwords “PA1” and “PA2” allow
access respectively to level 1 and level 2
parameters. In the standard configuration
passwords are not present. To enable
them (value 0) and assign them the
desired value, access the “Programming”
menu, within the folder with the “diS”
label. If passwords are enabled, they will
be requested:
- PA1 at the entrance of the
“Programming” menu (see the
“Programming Menu“ section);
- PA2 within the folder with the “Cnf”
label containing level 1 parameters.
