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).
