Control panel (cont.)
Light A - emergency shutdown This red light signals that the remote "emergency shutdown" button was pressed (external information received and stored in memory).
Light B -
This green light indicates that the
Light C -
◗input switch Q1 open;
◗RC input protection fuse
◗RC internal
◗battery charge
◗battery
◗RC electronic control board faulty, not calibrated or not personalized;
◗power supply board fault.
Light D - Mains 1 outside tolerances This yellow light signals that the Mains 1 voltage and/or frequency characteristics are outside tolerances.
Light E - battery room ventilation fault and/or harmonics filter temperature outside tolerances This yellow light is an alarm stored in memory signaling a battery room ventilation fault (external information that must be supplied from the room). If the installation includes a harmonics filter, this light will also signal an overtemperature of the filter’s inductor (information supplied).
Light F - battery temperature outside tolerances
This yellow light signals that the battery temperature is outside tolerances (external information supplied by special board ("Temperature Monitor" option).
Light G - battery charging
This yellow light signals that the battery is being recharged (vented batteries only). This light is deactivated in systems with sealed
Light H - inverter fault
This red light is an alarm stored in memory signaling an inverter fault. It can signify one or several of the following faults:
◗inverter shutdown due to inverter output voltage outside tolerances;
◗inverter output protection fuse (FU5-
◗inverter stack subassembly protection fuse blown (parallel systems);
◗inverter leg fault;
◗inverter output transformer over- temperature;
◗inverter leg
◗phase or output voltage fault (parallel systems only);
◗internal clock fault;
◗inverter control board faulty, not calibrated or not personalized;
◗power supply board fault.
Light I - battery discharged
This yellow light signals that the battery has reached its minimum voltage level, resulting in inverter shutdown.
Light J - inverter desynchronized with Mains 2
This light signals that the inverter output frequency has been voluntarily desynchronized with that of Mains 2.
Light K - transfer to inverter function fault
This red light is an alarm stored in memory signaling a fault in the systems for load transfer from Mains 2 to the inverter. It can signify one or several of the following faults:
◗inverter output switch K3N fault;
◗
◗static switch internal over- temperature;
◗static switch ventilation fault;
◗static switch power supply fault;
◗transfer function control board fault;
◗inverter control board not calibrated or not personalized;
◗power supply board fault.
Light L - overload
This yellow light is an alarm signaling one or several of the following faults:
◗inverter stack current more than 5% above rated current;
◗inverter output current more than 5% above rated current;
◗Mains 2 line current more than 5% above rated current;
◗inverter shutdown due to current limiting of output current.
Light M - Mains 2 outside tolerances
This yellow light signals that the Mains 2 voltage or frequency characteristics are outside tolerances.
Light N - maintenance position
This yellow light signals that devices QF1, Q4S, Q5N and Q3BP are set to the maintenance configuration. The UPS system is not available for load protection.
