Displaying alarms
List of alarms displayed:
MERY PC board fault 1: the main
control and monitoring board is faulty.
The board must be replaced by the
MGE UPS SYSTEMS after-sales
service.
Internal fault: this message informs
the user of an internal conditioner fault
which requires intervention by the MGE
UPS SYSTEMS after-sales service.
Voltage out of tol.: the amplitude of
the utility network voltage is out of the
permitted limits. Check the presence
and amplitude of the utility power
3 phases and neutral. The voltage
tolerances permitted are defined in the
section on "characteristics and
performances".

1 Choose the Alarms option using the
and
keys. The choice must be
displayed on the screen in reverse
video.
2 Confirm the Alarms option by
pressing the ENT key.
The following screen is displayed
during normal operation: conditioner
running and no anomaly present.

AC network clean
Frequency out of tol.: the utility power
frequency is out of the permitted limits.
Check the utility power frequency. The
frequency tolerances permitted are
defined in the section on
"characteristics and performances".
MERY PC board fault 2: the main
control and monitoring board is faulty.
The board must be replaced by the
MGE UPS SYSTEMS after-sales
service.
Internal overtemp: the conditioner has
been stopped by the thermal protection
thus avoiding damage to the
equipment. Check that the 3 ventilators
are operating correctly, that the air
vents are clean and check the
temperature of the room. The
temperature tolerances permitted are
defined in the paragraph on
"characteristics and performances".

faults to be displayed. The F2 "Diag"
key provides access to the level 1
diagnosis and the F3 "Reset" key
allows memorised faults to be
acknowledged.
Harm current > I nom: the harmonic
root mean square current absorbed by
the load exceeds the SineWave™
conditioner nominal current making it
operate in current-limiting mode.
the conditioner limits its
compensating current to its nominal
current rating (e.g. 30 A root mean
square for a 30 A SineWave™
conditioner);
the load is not entirely compensated;
the harmonic current difference (load
harmonic I - compensating I) remains
on the utility power;
problems may occur in your
installation depending on the rate of
harmonics remaining on the utility
power;
consult the MGE UPS SYSTEMS
after-sales service.
