6 V / 12 V / 24 V ?
ER1 (Error Code 1) appears when:
1. Battery clamps are connected incorrectly. The correct connection
is Red Clamp to Positive, Black Clamp to Negative.
2. The charger is powered on before being connected to the battery
(connect first, then power on).
3. The battery is completely flat. The charger requires at least 2 V to
add charge; below 2 V, it will not charge.
ER2 (Error Code 2) appears when:
1. A defective battery is connected.
Cannot be charged.
2. The battery voltage does not match the
selected charge mode (e.g., a 6 V battery
with a 12 V setting).
