OPERATIVE MODE
1) Remove the instrument from its case.
2) Set the internal dip switch V101 in closed condi-
tion
3) Re-insert the instrument.
4) Switch on the instrument.
DISPLAY FUNCTION
The upper display shows the measured value
while the lower display shows the programmed
set point value (we define the above condition as
“normal display mode”).
NOTE : When the rate of change (Grd1, Grd2) is
utilized, the displayed set point value may
be different from the operating set point.
It is possible to change the information on the
lower display as follows:
- Push FUNC pushbutton for more than 3
seconds but less than 10 seconds.
The lower display will show " r. " followed by
the power value of the OUT programmed as
"rEV" control output (from 0.0 to 100.0%
* ).
- Push FUNC pushbutton again. The lower display
will show "d." followed by the power value of the
OUT programmed as "dir" control output (from
0.0 to 100.0%
* ).
* The graphic symbol "
.
" means 100%.
- Push FUNC pushbutton again. The display will
return in "Normal Display Mode".
NOTE : The two power outputs are displayed only if
the relative function has been previously configured.
When no pushbutton is pressed during the time
out (see P36), the display will automatically return
in "Normal Display Mode".
In order to keep the desired information
continuously on the lower display, depress
s or
t push-button to remove the timeout.
When return in "Normal Display Mode" is desired,
push FUNC push-button again.
INDICATORS
°C
Lit when the process variable is shown in
Celsius degrees.
°F Lit when the process variable is shown in
Fahrenheit degrees.
SMRT Flashing when the first part of the SMART
algorithm is active.
Lit when the second part of the SMART
algorithm is active.
OUT1 It will flash with a duty cycle proportional
to the linear output value.
OUT2 Lit when OUT 2 is ON or alarm 1 is in the
alarm state.
OUT3 Lit when OUT 3 is ON or alarm 2 is in the
alarm state
Other functions are shown by decimal points:
REM = Flashing, when the instrument is
controlled via serial link.
SP2 = Flashing at slow rate when SP2 is used.
Flashing at fast rate when a set point from
serial link is used.
MAN= Flashing at slow rate, when the instrument
is in MANUAL mode.
