AFQ-4W
Instruction Manual 53
4.3.2.3.- ENABLE ALARM
This screen (Figure 55) allows us to control the different alarms:
Figure 55: Alarm activation screen.
Polarity alarm:
With the polarity alarm enabled, the active filter detects the direction of the load
measuring transformer current and if it detects inverse polarity (current towards
the mains) it returns to the initial conditions and restarts with the new conditions
in measuring the current. In the case of regenerative loads temporarily injecting
current into the mains, the polarity alarm will be activated.
With the polarity alarm disabled, if the load is injecting energy into the mains,
the AFQ-4W will measure negative active power and will stop neutralising
harmonics, balancing phases and compensating reactive energy. It will only
adjust the bus to the operating voltage.
When the active power is positive again, it will reperform all of the filtering
functions.
Disable the polarity alarm only in installations with loads temporarily
injecting current into the mains.
This option is enabled
by default and it is recommended not to
disable it.
Before starting the active filter with the polarity alarm disabled, check
the connection and polarity of the load measuring transformers.
