Fault Message
Symptoms and Troubleshooting

B a t t e r y
l o w v o l t a g e !
•
EVO™ is in
“FAULT MODE”
because the battery voltage has dropped to the set lower threshold
of “BATT LOW VOLTAGE”
(Section 4.4.2.9)
•
When the battery voltage drops to the threshold of parameter “BATT LOW VOLTAGE”
(Section
4.4.2.9)
, activation of this fault protection is initiated. The Red LED marked “Fault” will flash
once per second and the buzzer in the EVO will beep once per second.
The Inverter Section will
continue to operate normally, and the Green LED marked “Status” will continue to be ON steady
(
NOTE
: Fault message “Battery low voltage!” will not be displayed during this time)
•
If the battery voltage stays at or below the threshold of “BATT LOW VOLTAGE”
(Section 4.4.2.9)
for duration equal to parameter “LV DETECT TIME”
(See Section 4.4.2.10)
, only the Inverter
Section will be switched OFF
and fault message “Battery low voltage!” will be displayed.
The Red
LED marked “Fault” will now change to steady ON, the Green LED marked “Status” will switch
OFF and the buzzer in EVO will now beep steady.
The unit will get locked in this condition and
will be required to be switched off as follows:
o
The unit will automatically switch off after expiry of time set by parameter “LV CUT OFF
TIME”
(See Section 4.4.2.11)
.
[LCD Display / LED / Buzzer will be OFF]
, or
o
In case the time set by parameter “LV CUT OFF TIME”
(See Section 4.4.2.11)
has not
expired, switch off the unit manually
(See Section 3.2.2)
•
While in “Battery low voltage!” fault condition, if qualified AC input is made available before
expiry of time set by parameter “LV CUT OFF TIME”
(Section 4.4.2.11)
, the unit will automatically
reset to “Charging Mode”
provided the battery voltage is >9V for EVO-2212/3012 or >18V for
EVO-2224/4024
o
In case it is desired that the unit should not switch off due to “Battery low fault!” condition
after expiry of time set by parameter “LV CUT OFF TIME” (Section 4.4.2.11) but should
automatically reset to “Charging Mode” on availability of qualified AC input voltage with
battery voltage > 9V for EVO-2212/3012 or >18V for EVO-2224/4024
,
time value of
parameter “LV CUT OFF TIME” should be changed to 0 sec (Refer to Section 4.4.2.9.2)
•
If the batteries are charged by external charger connected directly to the batteries or through
the External Charger Input
(3, 4 in Fig 2.1 in the attached Owner’s Manual for EVO-2212/3012)
and
the battery voltage recovers to the set threshold of parameter “RESET VOLTAGE”
(Section
4.4.2.7)
before the expiry of time set by parameter “LV CUT OFF TIME”
(Section 4.4.2.11)
while in
“Battery low voltage!” fault condition, the Inverter Section will restart and “Battery low voltage!”
fault condition will be cleared.
