DISPLAY FUNCTIONS
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 setpoint (see P48).
By pushing the FUNC key for more than 3 s but
less than 10 s. it is possible to change the
information on the lower display as follows:

TC or RTD input is selected.
Push "FUNC" key again, the lower display will
show:
P.

programmed with "
rEU
" action (from 0 to 100%).
Push "FUNC" key again, the lower display will
show:
d.
followed by power value assigned to the output
programmed with "

Push FUNC pushbutton again. The display will
return in "Normal Display Mode".
