MGE UPS Systems Comet TM 5 - 30 kVA alarms

7.2 Comet installation and user manual: E-6761200XT/FA Merlin Gerin by MGE UPS SYSTEMS

alarms (cont')

■"11" - battery circuit breaker in "off" position:

indicates that the battery circuit is open (battery circuit breaker 4is in "off"

position). The load is no longer protected because battery power is no longer

available in the event of an AC input power failure. In the case of the "battery-free

frequency converter" option, it is normal for the "11" message to remain on;

■"12" - check battery: indicates that the battery should be checked (see Battery

maintenance in the Maintenance and servicing section);

■"13" - low battery shutdown warning: indicates that battery power will end

after a user-set time period. The user must take the required measures to secure

the load (load shedding, file saving and system shutdown, etc.);

■"14" - end of battery power;

■ "15" - battery fault: indicates a problem with the battery (see "battery

maintenance" in the "maintenance and servicing" section;

■ "16" - ambient T° fault: this display indicates that the ambient temperature is

outside the tolerance range (<0°C or > 40°C);

■ "17" - battery periodic test: this message indicates that the battery is in the

process of being checked;

■ "18" - battery manual test: this message indicates that the battery is in the

process of being completely discharged in order to update the battery monitoring

parameters;

■ "21" - inverter fault: indicates a fault in the inverter module 7 ; contact the

after-sales support department;

■ "22" - inverter overtemperature: indicates overheating inside the UPS; check

that the Comet ventilation system is working and that the ambient temperature is

within tolerances (see "appendices");

■ "25" - inverter overload: indicates an overload when the load is being

supplied via the inverter. Reduce the load;

■ "31" - Mains 2 voltage outside tolerance range: this display indicates that

the Mains 2 power supply voltage of the "static bypass" 3 is outside the

tolerance range;
