EVO™ Inverter/Charger is in
FAULT MODE
because of overload conditions in
Inverting Mode:
•
There will be no AC output because the Inverter Section will be switched OFF. The Green LED
marked “Status” will be switched OFF and the Red LED marked “Fault” will be steady ON. The
buzzer in EVO™ Inverter/Charger will beep steady
•
EVO™ Inverter/Charger will be latched in OFF condition and will require manual reset
by powering OFF, waiting for 1 minute and then powering ON again
•
Ensure that overloading is limited to the specified limit
Output voltage is less than 96Vrms for 300 cycles
(5 seconds at 60Hz)
Output power is over the Power Boost Rating (110%) for 30 min
Output power is over the Power Boost Rating (120%) for 5 minutes
Output power is over the Power Boost Rating (140%) for 30 seconds
Output power is over the Power Boost Rating (150%) for 5 seconds

!
EVO™ Inverter/Charger is in
FAULT MODE
because there is a short circuit on the output side in Inverter
Mode. Short circuit protection is activated when (i) the output current is over 18.33 Arms for EVO-
2212/2224, 25 Arms for EVO-3012 and 33.33 Arms for EVO-4024) and (ii) output voltage is less than
15 Vrms for 6 cycles
(0.1 second for 60 Hz)
.
(NOTE: Current is sampled every 33.3 µs)
•
There is no AC output because the Inverter Section has been switched OFF. The Green LED
marked “Status” will be switched OFF and the Red LED marked “Fault” will be steady ON. The
buzzer in EVO™ Inverter/Charger will beep steady
•
EVO™ Inverter/Charger will be latched in OFF condition and will require manual reset
by powering OFF, waiting for 1 minute and then powering ON again
NOTE:
If there is short circuit condition in Charging Mode i.e. when AC input is available, short circuit
condition on the output side will trip the AC input breaker. The load will be transferred to the Inverter
Section and the Inverter Section will then see short circuit condition and will shut down as described
above

f a i l u r e !
EVO™ Inverter/Charger is in
FAULT MODE
because AC input from Grid / Generator has been connected
to the AC Output terminals by mistake. 10VAC or above seen at the AC Output Terminals at the time of
boot up of EVO™ Inverter/Charger will activate this protection
•
The Green LED marked “Status” will be switched OFF and the Red LED marked “Fault” will be
steady ON. The buzzer in EVO™ Inverter/Charger will beep steady
•
EVO™ Inverter/Charger will be latched in OFF condition and will require manual reset
by powering OFF, waiting for 1 minute and then powering ON again
Check the connection. If there is 10V over at the output terminal, remove the connection.

o v e r h e a t
!
EVO™ Inverter/Charger is in
FAULT MODE
because the main Bidirectional Transformer in the EVO™
Inverter/Charger has overheated to 150°C
•
The Green LED marked “Status” will be switched OFF and the Red LED marked “Fault” will be
steady ON. The buzzer in EVO™ Inverter/Charger will beep steady
•
If in Inverting Mode, Inverter Section will be switched OFF. If in Charging Mode, the Transfer Relay
will be de-energized and the Inverter Section will be switched OFF.
•
Check that the fans are working properly, there is no blockage of air suction and discharge vents,
adequate cool replacement air is available and the ambient temperature is within the limits.
Reduce the load / “BULK CURRENT”
(Section 4.4.2.1)
•
The fault will be cleared when the transformer has cooled down to 80°C
