Note n.1
POWERS
Integration time of the average value (AVG) and peak value (MD) for
power (from 1 to 60 minutes)
CURRENTS
Integration time of the average value (AVG) and peak value (MD) for
current (from 1 to 60 minutes)
Note n.2
NORMAL
Classic Alarm with reference to a fi xed threshold or to maximum and
minimum delay and applicable hysteresis. "AVG" parameter is not used.
DERIV
"THRE" parameter becomes a % value, "AVG" parameter is used. The
instant value applied to the alarm on "MEAS" is compared with its value
mediated obtained on the basis of the time set on "AVG". When the
instantaneous value combined alarm differs in more (setting "Max") or less
(setting "MIN") from the average value (" AVG ") of the percentage set on
"THRE" the alarm goes on. With delay and applicable hysteresis.
Note n.3
MAX
Alarm setting in excess compared with the established conditions.
MIN
Alarm setting in decrease compared with the established conditions.
Note n.4
MEAS
indicates which register (and thus measure) the alarm is related.
See table n.1 input register.
THRE
Alarm threshold in absolute value, with the exception made for "DERIV"
in which the value inserted becomes a percentage.
Note n.5
AVG
Parameter to be used only in "DERIV" mode. Is the duration of the refe-
rence (in seconds) used to create a reference value for the istantaneous
readings.
Note n.6
NORMAL
Physical output of the alarm excited during the duration of the alarm. It
restores automatically
HOLD
Output remains excited until manual reset made via Modbus
PULSE-L
Output generate a 500ms impulse when the alarm goes on.
PULSE-S
Output generate a 100ms impulse when the alarm goes on.
Note n.7
PULSE
Enables exit function as impulsive
ALARM
Enables exit function as alarm
REMOTE
Enables function output via protocol Modbus
NO
Normally open
NC
Normally closed
Note n.8

P-EXP
Exported Active Power (Energy)
Note n.9
YES
Referred to SHUNT primary
NO
Referred to SHUNT secondary
Note n.10
ALARM 1
Alarm related to the physical output: DIGITAL OUT 1 (DO1, terminal 8)
ALARM 2
Alarm related to the physical output: DIGITAL OUT 2 (DO2, terminal 9)
ALARM 3
Only MODBUS alarm
ALARM 4
Only MODBUS alarm
MESSAGE "CFG ERROR"
During the set up operation a "CFG ERROR" message could appear. This means
that some wrong parameters are typed. To restore the factory default settings use the
following procedure (RESTORE FACTORY SETTING) seguire la seguente procedura:

ALARM SET UP EXAMPLE
To ensure that the exit "Digital out 1" remain excited for the alarm duration (latching)
when average active power (MEAS 344) exceeds the value of 100 kW, hysteresis, 5%
and latency of 5 seconds set the parameters such as table:

To ensure that the exit "Digital out 2" remain excited for the alarm duration (latching)
when average active power (MEAS 344) goes down the value of 90 kW, hysteresis, 5%
and latency of 5 seconds set the parameters such as table:
