ENTER IN THE SETUP
From the measures visualization, press at the same time the
A
and
C
keys, the message
Set Up
will appear on the
F
displays.
CHOOSE THE DIGITAL OUTPUT TO PROGRAM
Press repeatedly the
C
key until the message
SET DO1
(DO1 output) or
SET DO2
(DO2 output) appears on the
F
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
and
C
keys, it’s possible to select:
PULSE
(pulse emission),
ALR SYS
3PH
, (alarm on three phase value),
ALR PH_ 123
(alarm on minimum and maximum single phase value) and
BY_
REMOTE
(the digital output is managed using serial output). Press
A
key to confirm.
CHOOSE THE PARAMETER TO LINK TO THE DIGITAL OUTPUT
With an alarm modality set, it’s necessary to select the parameters associated to the alarm output; by pressing the
B
and
C
keys until the parameter choice appears on the third part (L3) of
F
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
F
display will appear the message
ALR Hi
with the high threshold value; confirming with the
A
key on the same
display will appear the message
ALR LO
with low threshold value. The
B
(to increase) and
C
(to decrease) keys are
used to set the high and the low thresholds 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
F
display will appear
ALR DLY
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.
The programming will be referred to the digital output indicated on
G
display (
DO1
o
DO2
).
