PROGRAMMING OF THE DIGITAL OUTPUT (
SET DO1
SET DO2
)
The DO1 and DO2 digital outputs have three modality of functioning:
PULSE
, alarm (
ALR
) and
REMOTE
command.
The DO1 modality setting is independent from DO2. For example it’s possible to set DO1 on
PULSE
(pulse emission)
and DO2 on alarm mode (
ALR
).
In the menu
SET DO1
and
SET DO2
it’s possible to program the function of all digital outputs. In these menus are
available the following modality:
PULSE
,
ALR
and
REMOTE
.
In
PULSE
mode the digital output DO1 will emit pulses proportional to the active energy counted while the digital
output DO2 will emit pulses proportional to the reactive energy counted. The proportionality will depend from the
PULSE
set in the
SETUP
and the duration of the impulse is set in the
TPL
voice of the
SETUP
.
The
ALR
modality is divided in two parts:
ALR SYS 3PH
and
ALR SYS 123
. With
ALR SYS 3PH
the digital
output will function as alarm verifying that the three phase value doesn’t exceed the threshold set (
ALR HI
and
ALR
LO
). With
ALR SYS 123
the digital output will function as alarm verifying that the maximum value of the single
phases doesn’t exceed the maximum threshold set (
ALR HI
) and that the minimum value of the single phases
doesn’t come down the minimum threshold set (
ALR LO
). The activation of the alarm output will come after some
seconds of delay set(
ALR DL
).
In the
REMOTE
mode, the output status will be decided from the status of the correspondent MODBUS register (see
protocol modbus manual for EMM).
