⊙（1）battery charger overheat
State：
（1）When “battery charger overheating” light flash, means
the charger internal protections function start due to charger long
time working or external environment temperature is too high.
(When the charger inside temperature reaches 75℃, the
protection begin working).In the meanwhile the charger
automatically cut off output, when internal temperatures below 75
℃, charger automatically start. If the "battery charger overheating"
light flashes, you can ignore it, and after the temperature drop, it
will automatically restart.
（2）When the "battery error" lights flash, means the battery is
not match with charger voltage. Means the voltage is higher or
lower than charger voltage. Such as factory set voltage 48V, the
battery voltage is 60V or 36V, then the "battery error" lights flash.
（3）When the “input voltage error” light flash, means the
charger’s current input voltage is not match with the factory setup
input voltage. Such as factory set voltage 220V, but connect to
110V, or factory set voltage 110V, but connect to 220V, then the
"input voltage error" lights flash.
（4）When the "battery overheat" light flash, means the
battery temperature is too high, then should stop charging the
battery.
Electrical characteristics:
ESF/ESFP series Chargers have request to AC input voltage.
ESF series AC input voltage is "85V-125V" or "185V-265V". ESFP
series Charger AC input voltage is "85V-265V". Please see details
of input voltage from Charger Label.
