troubleshooting Guide
• 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
"Fault" 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: Fault message
"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 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 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"
(LCD Display / LED / Buzzer will be OFF).
• 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
before 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, synchronize
with the AC input and then, transfer to the AC input at zero crossing. It will now
operate in Charging Mode
• EVO Inverter Charger is in FAULt MoDe because the battery voltage has dropped
to 9V or lower for EVO-2212 / 3012 or to 18 V or lower for EVO-2224 / 4024
• When the battery voltage drops to 9V or lower for the 12V version of EVO Inverter
Charger or 18V or lower for the 24V version, only the Inverter Section will be
switched OFF and message "Battery ultra low voltage!" will be displayed. Red
LED marked "Fault" 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
voltage!" 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" (LCD Display / LED / Buzzer will be OFF).
• 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
before 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, synchronize
with the AC input and then, transfer to the AC input at zero crossing. It will now
operate in Charging Mode
