PROGRAMMING OF THE DIGITAL OUTPUT (SET DO1 SET DO2) (only for vers. with digital output)
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 ELM).
