MOUNTING - DIMENSIONS
The device is designed for panel mounting. Drill a 29x71 mm hole and insert the instrument; secure it with the special brackets provided. Do not
install the instrument in damp and/or dirty places; in fact, it is suitable for use in places with ordinary or normal levels of pollution.
Keep the area around the instrument cooling slots adequately ventilated.

USING THE COPY CARD
The Copy Card is connected to the serial port (TTL) and allows rapid programming of the instrument parameters. Access Installer parameters by
entering ‘PA2’, scroll through the folders using and until folder FPr appears. Select it using , scroll through the parameters using
and , then select the function using (eg. UL).
• Upload (UL): Select UL and press . This function uploads the programming parameters from the instrument to the card. If the
procedure is a success, ‘y’, will appear on the display, otherwise ‘n’ will appear.
• Format (Fr): This command is used to format the copy card (recommended when using the card for the first time).
Important: the Fr parameter deletes all data present.This operation cannot be cancelled.
• Download:Connect the Copy Card when the instrument is switched off. At power-on, data is downloaded from the copy card to the
instrument automatically. At the end of the lamp test, the display will show ‘dLy’ if the operation was successful and ‘dLn’
if not.
UPLOAD
DOWNLOAD
OR
NOTE: After downloading, the instrument works with the settings of the new map just downloaded.

ACCESSING AND USING THE MENUs
The resources are organized into 2 menus which are accessed as follows:
• ‘Machine Status’ menu: press and release the key.
• ‘Programming’ menu: hold down the key for 5 seconds.
Either do not press any keys for 15 seconds (timeout) or press the key once, to confirm the last value displayed and return to the previous
screen.
PASSWORD
Password ‘PA1’: used to access User parameters. The password is not enabled by default (PS1=0).
To enable it (PS1≠0): press and hold for longer than 5 seconds, scroll through the parameters using and until you see the label
PS1, press to display the value, modify it using and , then save it by pressing or . If enabled, it will be required in
order to access the User parameters.
Password ‘PA2’: used to access Installer parameters. The password is enabled by default (PS2=15).
To modify it (PS2≠15): press and hold for longer than 5 seconds, scroll through the parameters using and until you see the
label PA2, press , set the value to ‘15’ using and , then confirm using . Scroll through the folders until you find the label
diS and press to enter. Scroll through the parameters using and until you see the label PS2, press to display the value,
modify it using and , then save it by pressing or .
The visibility of ‘PA2’ is as follows:
1) PA1 and PA2 ≠ 0: Press and hold for longer than 5 seconds to display PA1 and PA2. It will then be possible to decide whether to
access the User parameters (PA1) or the Installer parameters (PA2).
2) Otherwise: The password PA2 is amongst the level1 parameters. If enabled, it will be required when accessing the Installer
parameters; to enter it, proceed as instructed for password PA1.
If the value entered is incorrect, the label PA1/PA2 will be displayed again and the procedure will need to be repeated.

MACHINE STATUS MENU
Access the Machine Status menu by pressing and releasing the key. If no alarms are active, the ‘SEt’ label appears.
Use the keys and to scroll through all the folders in the menu:
- AL:alarms folder (only visible if an alarm is active);
- SP1:Setpoint 1 setting folder;
- Pb1:probe 1 - Pb1 folder;
Setting the Setpoint: To display the Setpoint value press the key when the ‘SEt’ label is displayed.
The Setpoint value appears on the display. To change the Setpoint value, press the and keys within 15
seconds. Press to confirm the modification.
Displaying probes: When label Pb1 is present, press the key to view the value measured by the corresponding probe (NOTE:
the value cannot be modified).
PROGRAMMING MENU
To access the ‘Programming’ menu, press the key for more than 5 seconds. If specified, an access PASSWORD
will be requested: ‘PA1’ for User parameters and ‘PA2’ for Installer parameters (see ‘PASSWORD’ paragraph).
User Parameter: When accessed,the display will show the first parameter (e.g. ‘diF’). Press and to scroll through all the parameters on
the current level. Select the desired parameter by pressing . Press and to modify it and to save the changes.
Installer Parameter: When accessed, the display will show the first folder (e.g. ‘CP’). Press and to scroll through the folders on the
current level. Select the desired folder using . Press and to scroll through the parameters in the current folder and select the
parameter using . Press and to modify it and to save the changes.
NOTE: Make sure you switch the instrument off and on again each time the parameter configuration is changed, in order to prevent mal-
functioning in the configuration and/or timing in progress.

DIAGNOSTICS
Alarms are always indicated by the alarm icon and the buzzer.
To switch off the buzzer, press and release any key; the corresponding icon will continue to flash.
N.B.: If alarm exclusion times have been set (see ‘AL’ folder in the parameters table) the alarm will not be signalled.

TELEVIS SYSTEM
The Televis remote control systems can be connected using the
TTL serial port (TTL-RS485 BusAdapter 130 or 150 interface
module must be used).
To configure the instrument to do this, you need to access the
Add folder and use the dEA and FAA parameters. RS485
