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:
- By pushing the FUNC pushbutton within 3s to
10s. The lower display will show " A." followed
by the current consumed by the load (driven by
the OUT 1) when
the load is in ON condition
(see also "OUT 1 failure detection").
- Push FUNC pushbutton again, the lower
display will show " b." followed by the leakage
current running in the load (driven by the OUT
1) when the load is in OFF condition (see also
"OUT 1 failure detection").
- Push FUNC pushbutton again, the lower
display will show "H." followed by OUT 1 power
value (from 0 to 100%).
- Push FUNC pushbutton again, the lower
display will show "C." followed by OUT 2 power
value (from 0 to 100%).
- Push FUNC pushbutton again. The display will
return in "Normal Display Mode".
NOTE : The "A", "b" and "C" informations will be
displayed only if the relative function has been
previously configured.
When no pushbutton are pressed during the time
out (see P35), 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.

algorithm is active.
OUT1 Lit when OUT 1 is ON.
OUT2 Lit when OUT 2 is ON or alarm 1 is in the
alarm state.
OUT3 Lit when the alarm 2 is in the alarm state.
Flashing with slow rate when the OUT 1
failure detection is in the alarm state.
