LOAD PROTECTED
ECO MODE
This is the normal display when there are no problems: the load is supplied by the inverter or the bypass AC source,
and battery backup is available.
LOAD NOT PROTECTED
ECO MODE
Ø
This display indicates that the load is supplied but has no battery backup. The arrow
Ø indicates the presence of
one or more problems specified in secondary messages.
The buzzer sounds continuously.
LOAD FORCED TO INVERTER
ECO MODE
The load has been transferred to the inverter following a specific request by the user.
Secondary Messages
LOAD ON MAINS 2
The load has been transferred to the bypass AC source (M2) and is no longer protected (only in on-line mode). The
buzzer sounds continuously.
MAINS 2 OUTSIDE TOLERANCES
TRANSFER DISABLED
CHECK MAINS 2
The bypass AC source (M2) frequency or voltage is outside tolerances and the inverter is unable to synchronize.
Transfer of the load from the inverter to the bypass AC source (M2) or vice-versa will result in an interruption of the
supply of power to the load. The buzzer sounds slowly and discontinuously.
BATTERY OVER TEMPERATURE,
CHECK VENTILATION
The battery temperature is outside tolerances. The buzzer sounds slowly and discontinuously
BATTERY ROOM VENTILATION
FAULT, CHECK VENTILATION
A fault requiring servicing has occurred in the battery room ventilation system. The rectifier/charger shuts down after
a 30-second time delay.
The user must take steps to re-establish correct operation of the ventilation system.
This message also signals an abnormally high temperature in the filter inductor.
The buzzer sounds slowly and discontinuously.
MAINS 1 OUTSIDE TOLERANCES
CHECK MAINS 1
The normal AC source (M1) frequency or voltage is outside specified tolerances and the rectifier/charger has shut
down. The inverter is on battery power.
MAINS 1 INPUT SWITCH Q1
IS OPEN
The normal AC input (M1) switch Q1 is open. It must be closed for rectifier/charger start-up. The buzzer sounds
slowly and discontinuously.
