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.3
Normal
Classic Alarm with reference to a fi xed threshold or to maximum and minimum delay
and applicable hysteresis. "AVG" parameter is not used.
1-OF-3
Consider also the 2 following registers of the selected one in "MEAS" . Works on a fi xed
max or min threshold with delay and applicable hysteresis. If one of the three register
exceed the threshold the alarm goes on. "AVG" parameter is not used.
3-OF-3
Consider also the 2 following registers of the selected one in "MEAS". Works on a fi xed
max or min threshold with delay and applicable hysteresis. When all the three register
exceed the threshold the alarm goes on. "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 diff ers
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.
UNBAL
Consider also the 2 following registers of the selected one in "MEAS".
parameter becomes a % value. Alarm goes on when one of the three register is
diff erent from the percentage set on "THRE" comply with the higher value of the three
read register if "MAX" is set on "TYPE", or comply with the lower value of the three
register if "MIN" is set on "TYPE"
With delay and applicable hysteresis.
Note n.4
MAX
Alarm setting in excess compared with the established conditions.
With the exception of "UNBAL".
MIN
Alarm setting in decrease compared with the established conditions.
With the exception of "UNBAL"
Note n.5
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" and "UNBAL"
in which the value inserted becomes a percentage.
Note n.6
AVG
Parameter to be used only in "DERIV" mode. Is the duration of the reference (in
seconds) used to create a reference value for the istantaneous readings.
Note n.7
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.8
PULSE
Enables exit function as impulsive
ALARM
Enables exit function as alarm
REMOTE
Enables function output via protocol Modbus
NO
Normally open
