13. Configuration menu (cont.)
The ‘ Tools’ ( tool ) menu groups several functions.
• at the ‘ Eco mode ’ ( Eco ) parameter, define the time to wait before the
display is powered off (while in ‘ normal mode ’ of operation). Default
value is 60 seconds. Configure ‘0’ to disable the function and maintain
the display always on.
• at the ‘ SOS mode ’ ( SoS ) parameter select ‘ on ’ to activate the output
signal to a predefined value. Select the value from 0 to 100% of the
active output range (4/20 mA or 0/10 Vdc). To deactivate the ‘ SOS
mode ’ select ‘ oFF ’. See section 6 for more information on the ‘ SOS
mode ’.
• at the ‘ Label ’ ( LAbL ) parameter, define an alphanumerical value to
be displayed on the display, when the instrument is in ‘ normal mode ’
of operation, or at the ‘ messages ’ function when the key ‘ LE ’ (
3
) is
pressed. The label can be used to identify the instrument with its
own internal factory code. If more than four characters are needed,
configure the ‘ Label 2 ’ ( LbL.2 ) parameter. The total label value is
the characters at ‘ label ’ followed by the characters at ‘ label2 ’. For
additional information and a list of available characters, see section 7.
• at the ‘ On error ’ ( on.Er ) parameter, configure the behavior of the
output signal, in case of error at the input signal (see section 16).
• select ‘ Output to high ’ ( to.hI ) to force the output signal to overrange
to maximum value
• select ‘
Output to low ’ ( to.Lo ) to force the output signal to
underrange to minimum value
• select ‘ Standard output ’ ( Stdr ) to overrange output signal to
maximum value in case of input signal overrange, and to underrange
output signal to minimum value in case of input signal underrange.

The key ‘ LE ’ (
3
) at the front of the instrument gives access to a
configurable set of information messages.
At the ‘
Key LE (messages function) ’ ( K.LE ) menu, select the informations
to be displayed when the front key ‘ LE ’ (
3
) is pressed (see section 10.5).
Select ‘ on ’ to activate each information.
• configure ‘ Input signal value ’ ( InP.S ) to ‘ on ’ to see the actual input
signal value and units (for example: ‘ Inp tc J ºC 528 ’).
• configure ‘ Output signal value ’ ( out.S ) to ‘ on ’ to see the actual output
signal value and units (for example: ‘ Out mA 08.3 ’)
• configure ‘ Label ’ ( LAbL ) to ‘ on ’ to read the value configured at the
‘ label ’ and ‘ label2 ’ parameters (see section 13.10).
• configure ‘ Process value ’ ( Proc ) to ‘ on ’ to read the process value as
configured at the process parameters (see section 13.6) (for example: ‘ Proc
1500 ’).
• configure ‘ Percentage ’ ( Prct ) to ‘ on ’ to see the actual percentage
of signal, where ‘0’ is the value assigned to the ‘ input signal low ’
parameter, and ‘100’ is the value assigned to the ‘ input signal high ’
parameter (see section 13.6) (for example: ‘ Prct 23.5 ’).
When more than one parameter is set to ‘ on ’, values will be displayed
sequentially, in the same order as they are listed in the menu, with a
middle dash ‘ - ’ between them. When all information has been displayed,
the instrument returns to ‘ normal mode ’ of operation.
