Troubleshooting Guide
TM Inverter/Charger. There is no buzzer in Remote Control EVO-RC
TM Inverter/Charger is in FAULT MODE because the battery voltage has dropped to
• EVO
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 Section will continue to operate normally and the Blue 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 Blue LED marked "Status" will switch OFF and the buzzer in EVO
will now beep steady. If the "Battery low voltage!" fault condition is not reset within the "LV
CUT OFF TIME", EVO
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
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 TM Inverter/Charger is in FAULT MODE because the battery voltage has dropped to 9V
or lower for the 12VDC input Models EVO-1212F / 1212F-HW / 2212 / 3012 or to 18 V or
lower for the 24 VDC input Models EVO-1224F / 1224F-HW / 2224 / 4024.
• When the battery voltage drops to 9V or lower for the 12 VDC version of EVO
Charger or 18V or lower for the 24 VDC 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 Blue LED marked "Status" will be switched OFF and the
buzzer in EVO TM 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
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 TM 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
