Technical Data - Comar Condensatori BMR 6 Serie Instrucciones De Instalación Y Funcionamiento

HIGH CURRENT: the current measured from the C.T. exceeds the
110% In. the alarm relay operates in the programmed mode.
LOW CURRENT: the current measured from the C.T. is less than
6%In for 5secs.: if this conditions during more than 2 min.
the regulator switch OFF all the capacitors banks, and the
alarm relay operates in the programmed mode.
UNDER COMPENS: this alarm appears when the PFC equipment
does not reach
and the alarm relay operates in the programmed mode.
OVER COMPENS: this alarm appears when the cosφ is Capacitive
for 2 min; the regulator switches OFF all the capacitors
banks and the alarm relay operates in the programmed
mode.
HIGH THD%: the harmonic distortion value is more than the
THERM THD% value set on the PAR SETUP menu; the
regulator switches OFF all the banks and the alarm relay
operates in the programmed mode.
OVER THD%: the harmonic distortion value is over the
instantaneous OVER THD% value set on the PAR SETUP
menu; the regulator switches OFF all the banks and the
alarm relay operates in the programmed mode.
OVER TEMPERATURE: the temperature measured by the probe
(if connected) is over the value set in the PAR SETUP menu
the regulator switches OFF all the banks and the alarm relay
operates in the programmed mode.
MAIN FAILURE: no supply voltage or less then the minimum limit
on the volt signal input gate. The ALARM relay switch-on
end disconnection of all the capacitors banks (alarm
displayed only in BMR8 and 12)
The normal functions resume when the alarm condition ends and
the alarm relay is reset.
