Displaying the alarms (if present)

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)

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:

-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.

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)

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 (if the

password is correct) the label of the first

folder will follow.

To scroll through the other folders, use

the “UP” and “DOWN” keys.

If the password is wrong, the display will

show the PA1 label again.

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

everytime it is changed the configuration

of the parameters: this prevents malfunc-

tioning on regulation and delay time

occuring.

PASSWORD

The password “PA1” allows access to pro-

gramming parameters. In the standard

configuration password is not present.

To enable (value≠0) and assign it the

desired value, access the “Programming”

menu, within the folder with the “diS”

label. If password is enabled, you will see

it at the entrance of the “Programming”

menu (see the “Programming Menu“ sec-

tion).

MANUAL ACTIVATION OF THE

DEFROSTING CYCLE

To manually activate the defrosting cycle,

press the “UP” key for 5 seconds.

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:

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.

Upload

This operation loads the programming

parameters from the instrument.

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.
