EMA11 - USER MANUAL
-43-
11.2) MAIN MENU SETUP
The main menu or SETUP page is configured in the following way:
•
GENERAL , includes the settings of KCT (current ratio), KTV (voltage
ratio), MODE (4 wires, 3 wires, Aron), MEASURE TIME (time constant of
measure filter), WARNINGS, B.LIGHT (Backlit on display timing),
DISPLAY (positive or negative visualization), DEF. PAGE TIME (time of
wait before to come back to default page), SYNC. (frequency
synchronization), CLOCK (clock settings), PASSWORD (pin-code to
avoid that someone not authorized could modify the setup), ACCESS
(code to enable option function like harmonics and/or time-bands), USER
PAGE (to set the measures to display in user page) and V UNBALANCE.
•
SERIAL COMM , includes the settings of PROTOCOL (ASCII or MODBUS), ADDRESS (logical
number, node or address), COM1 (serial port 1, integrated), COM2 (serial port 2, expansion board).
•
AVERAGE , includes the settings of SYNC. AVG (synchronism of calculation average), TYPE (fixed
or mobile), TIME AVG (integration time for the calculation of the average parameters) and DT
MOBILE (sliding time of window mobile).
•
ENERGY , includes the setting of TYPE (energy counters in kWh or in MWh), PRESET (allows to set
the initial value of total ENERGY counter and the generic COUNTERS) and TIMEBANDS (with all
parameters to manage the power consumption in different periods)
•
STORAGE , includes the settings of MINMAX (minimum and maximum values storing), AVG.POW.
(the average consumption of active and reactive powers storing), HARM. (harmonic storing up to the
31
st
order for both current and voltage for each line), TRIGGER (start of storing from pulse on digital
input).
•
DIGITAL OUTPUT , sets the OUT INDEX number of digital output, TYPE (type of alarm; always on,
max. threshold, min. threshold, external band, energy pulse, always off), MEASURE CODE (the
parameter to associate with the digital output), VALUE (the value to set as threshold or, pulse),
TIME (delay time by enabling the digital output or duration of impulse), HYSTERESIS, INFVALUE
and SUPVALUE (lower value and higher value for alarm of external band).
•
DIGITAL INPUT , sets the type of acquisition: Not used, Clock Synchronization, Periods, Counters
(INPUT, NAME, WEIGHT) or External Synchronization.
•
ANALOG OUTPUT , set the analog output number, OUT INDEX, TYPE (disable, 0-20mA and 4-
20mA), MEASURE CODE (the parameter to associate at analog output), MIN and MAX (lower value
and higher value of the variable to associate at current output).
•
RESET , allows to make a RESET MEASURES, RESET SETUP, RESET STORAGE, RESET
COUNTER, RESET MAX DEMAND and RESET GLOBAL.
•
EXIT SETUP , allows the operator to exit from the main menu or setup page in order to reach the
instantaneous value page. Before exiting the page the instrument will question the operator if he
might to save the STORAGE Setup in case one or more parameters have been modified.
All the above mentioned voices will be described on the following chapters.
