HOW TO ENTER THE ‘FORCE MENU
With the instrument in ‘normal mode’ of operation (see section 12.2), press
and hold the ‘UP’ (5) key for 1 second. The horizontal leds light from bottom
to top. When the upper led lights, the instrument enters into the ‘force’ menu.
If the ‘UP’ (5) key is released before entering into the ‘force’ menu, the
horizontal leds light downwards from top to bottom, and the instrument
returns to ‘normal mode’ of operation.
HOW TO OPERATE INSIDE THE ‘FORCE’ MENU
The available functions inside the ‘force menu can be congured (see
section 13.7). By default, ‘Force High’, ‘Force Low’, ‘Force Set’ and ‘Tare’ are
available. Inside the ‘force’ menu:
press the ‘UP’ (5) key to move to the next function.
press the ‘SQ’ (<) key to activate the selected function.
When the function is active, the display will remain ashing. Press the SQ
(<) key to deactivate the function (display stops ashing), or wait for the
rollback to activate.
DESCRIPTION OFFORCE’ FUNCTIONS
The ‘force’ functions allow to manually force the output signal to the low
and high levels of the output signal selected. These functions allow to
easily validate the correct function of remote elements connected to the
instrument output, such as PLC, HMI’s, SCADAs, etc.
The ‘force low’ function sets the output signal to the minimum value of the
selected range (4 mA or 0 Vdc or the value congured at the output_low
parameter).
The ‘force high’ function sets the output signal to the maximum value of the
selected range (20 mA or 10 Vdc or the value congured at the ‘output_high
parameter).
The ‘force setfunction sets the output signal to a value between 0 and 100%
of the maximum selected range (4 to 20 mA or 0 to 10 Vdc or the range
congured at the ‘output_low’ and ‘output_high’ parameters). When entering
the ‘force set’ function, the display reads ‘50’ (the output is forced to 50% of
the congured range). Use keys UP’ (5) and ‘LE’ (3) to move up to 100% or
down to 0% of the congured range.
12.4 How to operate the ‘Force’ menu
HOW TO ACTIVATE ‘MESSAGES FUNCTION
With the instrument in ‘normal mode’ of operation (see section
12.2), press the ‘LE’ (3) key to activate the ‘messages’ function. The
messages’ function displays information about the instrument status.
The information available is congurable (see section 13.8).
The ‘messages’ function ends when all the information has been
displayed or front keys ‘UP’ (5) or ‘SQ’ (<) are pressed. The ‘display
returns to ‘normal mode’ of operation.

FAST CONFIGURATION
The fastest way to congure the instrument is to activate one of the
predened conguration codes (see section 8).
Access the ‘conguration menu’ and enter the ‘Function code’ (codE)
menu entry. The code displayed is the current active input - output range.
Select the new code and validate. Selecting a code automatically exits
the ‘conguration menu’ and activates the new conguration.
*
There are different codes for 4/20 mA and 0/10 Vdc output
signals.
To customize the input and output signals, see the Advanced scaling
section of the ‘conguration menu’ (see section 13.4).
ADVANCED CONFIGURATION
Additional conguration parameters are available at the conguration
menu’. The operator can customize the input and output signal ranges,
the messages seen on display, the functions available at the ‘force’ menu,
the messages associated to the ‘LE’ (3) key, activate lters, password
function, etc.
See section 13 for a detailed explanation on the ‘conguration menu’.
12.6 Fast and advanced congurations
DESCRIPTION OFTARE’ FUNCTION
The ‘tare’ function allows to view the actual value of the tare and manually
apply a tare. Press the ‘SQ’ (<) key to enter the ‘tare’ function, and access
the actual tare value expressed in millivolts’ (see section 10.1) with 2 decimal
points. Press again the ‘SQ’ (<) key to apply a new tare. The instrument
will show ‘ok’ while the new tare is applied, and will return back to indicate
the new tare value applied. Tare value can also be accessed and manually
modied at the ‘conguration menu’ (see section 13.4).
HOW TO EXIT ‘FORCE’ MENU
To exit the ‘force’ menu, press the ‘LE’ (3) key, or press the key ‘UP’ (5) key
until the parameter ‘----’ appears, and select by pressing the ‘SQ’ (<) key, or
wait without pressing any key until the automatic ‘rollback’ activates.
When exiting the ‘forcemenu, the horizontal leds light down from top to
bottom, and the instrument returns to ‘normal mode’ of operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument
exits the ‘force’ menu and returns to ‘normal mode’ of operation.
