Troubleshooting and Indicators

Error Lamp Status

Check connections, battery type, and charging interruptions for error lamp.

Power Lamp Status

Steady light indicates mains connection; flashing light means energy save mode.

Charging Stage Details

Step 1: Desulphation

Detects and removes sulphate from lead plates to restore battery capacity.

Step 2: Soft Start

Tests if the battery can accept charge, preventing charging of defective batteries.

Step 3: Bulk

Charges with maximum current until approximately 80% battery capacity.

Step 4: Absorption

Charges with declining current to maximize up to 100% battery capacity.

Step 5: Analyse

Tests if the battery can hold charge; identifies batteries needing replacement.

Step 6: Recond

Increases voltage for controlled gassing, mixing acid and restoring energy.

Step 7: Float

Maintains battery voltage at maximum level with a constant voltage charge.

Step 8: Pulse

Maintains 95-100% capacity by pulsing when voltage drops.

Connecting and Disconnecting

Connecting to Battery

Connect red clamp to positive pole, black clamp to chassis, then to wall socket.

Disconnecting from Battery

Disconnect from wall socket first, then black clamp, then red clamp.

Positively Earthed Batteries

Connect black clamp to negative pole, red clamp to chassis for positive earth systems.
