Example :
Output DO1 (RO1) : set to standard output mode (details via communication link only)
Output DO2 (RO2) : set to pulse mode, 20 pulses/kWh of energy ΣEP-
The standard output function can be used at instruments equipped with communication link only – it can be adjusted only via
connected PC using ENVIS program ( see ENVIS program manual ). The pulse output function can be set simply from the
instrument panel too.
The alarm lights A1, A2 setup is not displayed, it is available via a communication line only. You can only check if the setup is
the same as corresponding DO1/2 (RO1/2) setup or not. If any of signal lights A1, A2 is set, the outlines of both lights appear
on the display. They stay hidden when function of both lights is disabled.
2.12.3 Pulse Output Mode
Any of digital outputs or alarm lights can be set as transmitting electricity meter. The frequency of generated impulses can be
set depending on values of measured electric energy by the embedded electricity meter unit.
You can set to impulse output mode not only the
DO
-type (solid-state) outputs, but the
RO
-type (electromechanical
relay) outputs too. But note lifetime of electromechanical relays, they have limited number of switchings.
The outputs DO1/2 (RO1/2) can be set to impulse output mode both manually from the instrument panel and remotely via a
communication line. The manual setup is available in parameter group 11. After entering editation, set edited parameter
(range 0.001÷999) with arrow keys and select desired energy with the
key.
Example :
Output DO1 (RO1) : 0.1 pulses/kWh = 1 pulse / 10 kWh, energy ΣEP+ (no additional symbol)
Output DO2 (RO2) : 5 pulses/kvarh , energy ΣEQL (due to symbol
)
By setting any of the DO1/2 (RO1/2) outputs from the instrument panel, corresponding alarm light A1/A2 is set in the
same way automatically too. Then the DO1/2 (RO1/2) activity can be checked by the A1/A2 lights on the instrument
display. Separate setup of the lights is available using the ENVIS program via a communication line only. If any of
lights is set different from corresponding DO1/2 (RO1/2) output the symbol ▲ preceeding appropriate setup
appears.
Even if an instrument is equipped with neither any digital output nor any communication line, you can set impulse
function of alarm lights A1, A2 by setting the DO1/2 (RO1/2) outputs.
