2. Buzzer is available only in EVO Inverter Charger. There is no buzzer in Remote Control EVO-RC
Fault Message
Symptoms and Trouble Shooting
Battery low voltage!
• EVO Inverter Charger is in
FAULT MODE
because the battery voltage has
dropped to the set lower threshold of “BATT LOW VOLTAGE”
• When the battery voltage drops to the set lower threshold of “BATT LOW
VOLTAGE”, activation of this fault protection is initiated. The Red LED marked
“Alarm” will flash once per second and the buzzer in EVO Inverter Charger 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:
“Battery
low voltage!” will not be displayed during this time)
• If the battery voltage stays at or below the above threshold for duration equal
to the set “LV DETECT TIME”, only the Inverter Section will be switched OFF
and message “
Battery low voltage!
” will be displayed. The Red LED marked
“Alarm” will now change to steady ON, the Green LED marked “Status” will
switch OFF and the buzzer in EVO Inverter Charger will now beep steady. If the
“Battery low voltage!” fault condition is not reset within the “LV CUT OFF TIME”,
EVO Inverter Charger will be shut down completely after the expiry of “LV CUT
OFF TIME”.
• 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 EVO Inverter Charger Man-
ual) and the battery voltage recovers to the set “RESET VOLTAGE” before the expiry
of “LV CUT OFF TIME” while in “Battery low voltage!” fault condition, the Inverter
Section will restart and “Battery low voltage!” fault condition will be cleared.
• While in “Battery low voltage!” fault condition, if AC input is made available be-
fore the expiry of “LV CUT OFF TIME”, the “Battery low voltage!” fault condition
will be cleared. The EVO Inverter Charger will restart in Inverter Mode, synchro-
nize with the AC input and then, transfer to the AC input at zero crossing. It will
now operate in Charging Mode
Battery ultra low voltage!
• EVO Inverter Charger is in
FAULT MODE
because the battery voltage has
dropped to 9V for EVO-2212 / 3012 or to 18 V for EVO-2224 / 4024
• When the battery voltage drops to 9V for the 12V version of EVO Inverter Char-
ger or 18V for the 24V version, only the Inverter Section will be switched OFF
and message “
Battery ultra low voltage!
” will be displayed. Red LED marked
“Alarm” will be steady ON, the Green LED marked “Status” will be switched OFF
and the buzzer in EVO Inverter Charger will beep steady.
• When the duration in “Battery ultra low voltage!” fault condition is equal to the
set duration of “LV DETECT TIME”, the message will change to “Battery low volt-
age!” If “Battery low voltage!” fault condition is not reset within the “LV CUT
OFF TIME”, EVO Inverter Charger will be shut down completely after the expiry
of “LV CUT OFF TIME”.
• 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 EVO Inverter Charger
Manual) and the battery voltage recovers to the set “RESET VOLTAGE” before
the expiry of “LV CUT OFF TIME” while in “Battery low voltage!” fault condition,
the Inverter Section will restart and “Battery low voltage!” fault condition will be
cleared.
• While in “Battery low voltage!” fault condition, if AC input is made available be-
fore the expiry of “LV CUT OFF TIME”, the “Battery low voltage!” fault condition
will be cleared. The EVO Inverter Charger will restart in Inverter Mode, synchro-
nize with the AC input and then, transfer to the AC input at zero crossing. It will
now operate in Charging Mode
