ENTER IN THE SETUP
To program the digital output from the measures visualization, keep pressed the
A
key (5 seconds), the message
will appear on the
C
display.
CHOOSE THE DIGITAL OUTPUT SETTING
Press repeatedly the
B
key until the message
or
appears on the
C
display. Press the
A
key to
select this setting.
SELECT THE MODALITY OF FUNCTIONING OF THE DIGITAL OUTPUT
To select the functioning mode, using the
B
key, it’s possible to select:
,
,
.
(pulse emission) with DO1 linked to
(active energy) parameter and DO2 linked to
(reactive energy)
parameter;
, (alarm on three phase value),
(alarm on minimum and maximum single
phase value) and in a three-phase or in a balanced three-phase connection with connection mode set on
or
;
alarm on the minimum value and maximum value of L1 phase in a single-phase connection with
connection mode set to
. Confirm the setting, pressing the
A
Key.
CHOOSE THE PARAMETER TO LINK TO THE DIGITAL OUTPUTS
With an alarm modality set, it’s necessary to select the parameters associated to the alarm output; by pressing the
B
key
until the parameter choice appears on the third part (L3) of
C
display and the glowing the corresponding led on the
D
bar.
Press
A
key to confirm the set.
SET THE HIGH AND THE LOW THRESHOLDS
On
C
display
will
appear
the
message
with
the
high
threshold
value;
confirming
with
the
A
key
on
the
same
display
will
appear
the
message
with
low
threshold
value.
The
high
and
the
low
thresholds
values
are
set
using
the
B
key
to
increase
the
values,
and
A
and
B
key
pressed
together
(starting
from
the
condition
B
key
pressed)
to
decrease
the
values.
The
range
depends
by
the
parameter
and
it
is
linked
to
the
CT
and
VT
ratios.
Pressing
A
key
to
confirm.
The threshold set is linked with CT and
VT ratios, for this reason it’s necessary to make this operation after the
programming of the CT and VT. The end scale value must be confirmed when CT and VT ratios are modified.
The low threshold will be lower than high threshold. If the high threshold is set as OFF the low threshold will have the
range of the high threshold.
SET THE DELAY TO THE DIGITAL OUTPUT ACTIVATION
Now it’s possible to set the delay that will pass between the alarm condition set and the activation of digital output. On
C
display will appear
and the value expressed in seconds (range 1÷900). The modification of the value is done in
the same way of the threshold set. With the confirmation (
A
key) the set is complete.
PROGRAMMING OF THE HOURS COUNTER (
)
The hour counter will be increased when the measure of the parameter will exceed the set threshold value.
(the visualization depends on the settings and the I/O status)
To chose the parameter
(see the variable list)
Set the threshold
Increase
Decrease
Confirm and end of hour counter settings.
SELECT THE PARAMETER TO LINK TO THE HOURS COUNTER
From the previous setting, pressing the
C
key it’s possible to set the hours counter: the message
appears on
the
F
display. Press the
A
key to define the parameter to link to the hours counter. Press more time the
B
key to select the
parameter and the
A
key to confirm it.
SET THE THRESHOLD
Subsequently it’s necessary to set the threshold using the
B
(to increase) and
C
(to decrease) keys. Confirm with
A
key.
