NETWORK ANALYZER USER MANUAL
51
In order to set an alarm, it is needed to define the parameter associated to the alarm, the alarm type (cross
up over threshold, or cross down under threshold), the threshold value for the parameter, the activation
delay and the hysteresis for the turn off threshold.
Setting
Description
Parameter
Voltage (L1, L2, L3, L1-L2, L2-L3, L1-L3), Current (total, L1, L2, L3, neutral,
ground), Active Power (total, L1, L2, L3), Reactive Power (total, L1, L2, L3),
Apparent Power (total, L1, L2, L3), THD Voltage (L1, L2, L3, L1-L2, L2-L3, L1-L3),
THD Current (L1, L2, L3, neutral), Unbalance Voltage (L-L, L-N), Unbalance
Current, Frequency, Power Factor (total, L1, L2, L3), Count down Timer.
Alarm Type
Cross up or Cross down.
Threshold
Manual entry from 0 to 999k.
Delay
Manual entry from 0s to 900s.
Hysteresis
Manual entry from from 0% to 40%.
Logs
Enable or Disable the logging of alarms inside notifications.
1a. In case an alarm has been set, it will present
an edit symbol ( ) in the list of alarms. A tap
on an alarm with edit symbol allows to edit
an existing alarm.
1b. In case an alarm is not completely set, it will
present a “+” in the list of alarms. A tap on an
alarm with “+” allows to create a new alarm.
7.6.Complex alarms
In this section it is possible to configure the complex alarms, allowing to combine simple alarm into single
entity through specific logics.
Up to 4 complex alarms can be configured on the device. It is possible to create an alarm logic that will allow
the alarm activation only in case specific conditions take place.
Each complex alarm can be linked to up to 4 simple alarms, selected along with OR / AND logical operator.
When OR is selected alarm will be tripped every time one of the conditions of the equation will turn positive;
when AND is selected alarm will be tripped every time all the conditions of the equation will turn positive.
Complex alarm trip can be registered in the notifications (alarm section) and/or alarm output is set High.
Once logical equation will turn negative again, complex alarm is turned off, thus digital output is turned off
or/and it is registered in the notifications log (alarm section).
1a. In case an alarm has been set, it will present
an edit symbol ( ) in the list of alarms. A tap
on an alarm with edit symbol allows to edit
an existing alarm.
1b. In case an alarm is not completely set, it will
present a “+” in the list of alarms. A tap on an
alarm with “+” allows to create a new alarm.
