NOTE n.3
NORMALE 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 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.
UNBAL Consider also the 2 following registers of the selected one in “MEAS”.
“THRE” parameter becomes a % value. Alarm goes on when one of the
three register is different 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 refe-
rence (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
ALLARME 1 Only MODBUS alarm
ALLARME 2 Only MODBUS alarm
ALLARME 3 Only MODBUS alarm
ALLARME 4 Only MODBUS alarm
NOTE n.9
LOW Associated scale value starts at 0 and 4 mA
HIGH Full scale value associated with 20 mA
