QNA500 analyzer will record all variables selected every X minutes once the variables have been
selected and the new configuration has been sent, in accordance with the programmed standard
recording time period.
These records are saved in various files, depending on the type of data. Refer to the file section for
more information related to the location of these information records.
8.11.- ALARM SETUP (Digital objects)
QNA500 power quality analyzer can configure a list of alarms (up to 16 alarms) for an improved and
more accurate supervision of the electrical installation and its status.
These alarms can be simply recorded in the memory or used to create actions in other MULTIFIT
modules, such as, for example, the activation of the relay of a M-8IO module.
There are 2 different types of alarms (or digital objects), as described:
• ALARM OBJECTS: can enable any alarm condition associated to an electrical variable
measured by the QNA500 module.
• ENERGY OBJECTS: these are necessary when associating a pulse output of a M-8IO module.
The most common application is where the pulse outputs can produce pulses proportional to
the energy (A+, A-, Q1, Q2, Q3 or Q4) measured by the QNA500. To do so, first activate an
energy object and activate the pulse output on the M-8IO module. This configuration is
explained in the corresponding chapter of this module.
These alarms (or digital objects) can be associated with the following variables:
