Eliwell IC 901 A - User Manual

THE USER INTERFACE
The user has a display and four keys for
controlling status and programming of the
instrument.
KEYS AND MENUS
UP key Scrolls through the menu items
Increases the values
DOWN key Scrolls through the menu items
Decreases the values
FNC key ESC function (exit)
SET key Accesses the setpoint
Accesses the menus
Confirms the commands
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
(See Machine Status Menu Diagram)
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” sec-
tion).
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
(See Programming Menu Diagram)
To enter the “Programming” menu, press
the “set” key for more than 5 seconds.
If specified, the access PASSWORD will be
requested, (parameter “PA1”), and the
label of the first folder will follow.
To scroll through the other folders, use
the “UP” and “DOWN” keys; the folders
contain the level 1 and 2 parameters. The
level 2 parameters may be protected by a
second password (parameter “PA2”).
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 to move to the next parameter.
PLEASE NOTE: It is suggested to switch-off
and switch-on again the instrument every-
time it is changed the configuration of the
parameters: this prevents malfunctioning
on regulation and delay time occuring.
PASSWORD
The password “PA1”allow access to level 1
parameters. In the standard configuration
passwords are not present.
To enable them and assign them the
desired value, access the “Programming”
menu, within the folder with the “diS”
label.
If passwords are enabled, you will see PA1
at the entrance of the
“Programming” menu;
COPY CARD
The Copy Card is an accessory connected
to the TTL serial port which allows pro-
gramming quickly the instrument parame-
ters. The operation is performed as fol-
lows:
Fr-Format
This command allows copy card format-
ting, an operation recommended in case
of first use.
Warning: if the copy card has been pro-
grammed, using the “Fr” the data entered
are erased. This operation cannot be can-
celled.
UL-Upload
This operation loads the programming
parameters from the instrument.
dL-Download
This operation downloads to the instru-
ment the programming parameters.
The operations are performed accessing
the folder identified by the “FPr” label and
selecting, according to the case, “UL”, “dL”
or “Fr” commands; the operation is con-
firmed by pressing the “set” key. If the
operation is successful an “y” is displayed,
on the contrary, if it fails a “n” will be dis-
played.
NOTE:
• UPLOAD: instrument --> Copy Card
• DOWNLOAD: Copy Card --> instru-
ment.
KEYBOARD LOCKING
The instrument includes a facility for dis-
abling the keyboard, by programming the
“Loc” parameter (see folder with “Dis”
label). If the keyboard is locked, you can
still access the programming menu by
pressing the “set” key.
The Setpoint can also be viewed.
