3.2. Instruccions de cablejat

• Main Battery (Hauptbatterie):
  • Connect the positive (+) terminal of the charger to the positive (+) terminal of the main battery using a red cable (2.5-10 mm²).
  • Connect the negative (-) terminal of the charger to the negative (-) terminal of the main battery using a black cable (2.5-10 mm²).
  • Install a fuse (Sich. 1) of 25-40 A in the positive line, as close as possible to the main battery.
• Optional Start Battery (Startbatterie):
  • Connect the secondary positive (+) output (labeled "II START") of the charger to the positive (+) terminal of the start battery using a red cable (1.5-2.5 mm²).
  • Connect the negative (-) terminal of the start battery to the vehicle chassis (Karosserie).
  • Install a fuse (Sich. 2) of 15 A in the positive line, as close as possible to the start battery.
• Preparació del cable: Strip cable ends by approximately 10 mm before connecting them to the terminals.
• Vibració Dampeners: Do not remove the rubber sleeves intended for vibration reduction.
• Connexió de control remot: The charger has a connection point for an optional remote control.

3.3. Selecció del tipus de bateria

Set the battery type for the main battery (Hauptbatterie I) using the white-colored selector switch on the charger. The available settings are:

1. Lead Acid / AGM 1 (14.4V): Per a bateries estàndard de plom-àcid i AGM.
2. Gel (14.4V): For gel batteries.
3. AGM 2 (14.7V): For specific AGM batteries requiring a higher charging voltage.
4. LiFePO4 (14.4V): For Lithium Iron Phosphate batteries.

Important Note for LiFePO4 Batteries: For safety reasons, the device operates with LiFePO4 batteries only when a temperature sensor is connected. Mount the temperature sensor to the negative (-) pole of the battery.

4. Instruccions de funcionament

The VOTRONIC charger offers various charging programs and features to optimize battery life and performance.

4.1. Charging Programs Overview

• "Gel" Program (IU1oU2oU3 characteristic curve): Designed for sealed, gas-tight gel/dryfit batteries. This program uses a higher charging voltage and longer U1 hold times for fast charging and high storage capacity, preventing long-term battery "starvation."
• "AGM" Program (IU1oU2oU3 characteristic curve): For sealed, gas-tight AGM (Absorbent Glass Mat) batteries. It features a particularly high U1 level with adapted hold times for full charge, followed by a moderate U2 level for charge maintenance (plate and round cell technology).
• "Universal" Program (IU1oU2oU3 characteristic curve): A universal program for charging and maintaining lead-acid batteries in vehicles (mobile/stationary mixed use). With an average U1 level, it provides short charging times, good charge factor, and acid mixing for open and closed, low-maintenance and maintenance-free batteries, electric batteries, solar lamps, heavy-duty batteries, and AGM batteries with normal U1 level.
• "LiFePO4" Program (IU1oU2oU3 characteristic curve): Adapted for Lithium-LiFePO4 batteries with their own prescribed or integrated BMS and protection circuit. A special rest maintenance automatically keeps the LiFePO4 battery at a life-extending charge level of 50-80% when the vehicle is parked (seasonal operation). It also buffers 12V consumers and the vehicle's starter battery. A regular automatic wake-up function activates cell balancing.

4.2. Característiques clau

• Parallel and Buffer Operation: The battery is still charged or fully maintained even with simultaneous consumption.
• Silent Run Function: Optimized operation at the touch of a button.
• Funció d'alimentació: Allows powering consumers without a battery.
• Charge Cable Compensation: Voltage losses on charging cables are adjusted.
• Parallel Operation with Other Systems: Can operate in parallel with solar systems, wind generators, gasoline generators, alternators, etc., on a single battery.
• Charge Aid for Deeply Discharged Lead Batteries: Gentle pre-charging of lead batteries down to 8V, then powerful support even if consumers are still on.
• Separació de la bateria: Automatic separation of batteries in case of power failure, overheating, or incorrect operation (safety switch per charge output).

5. Manteniment

• Lead Battery Regeneration: The charger performs regeneration of lead batteries twice a week during long periods of inactivity to counteract harmful acid stratification, extending battery life.
• LiFePO4 Maintenance: The LiFePO4 program includes an automatic stop and a moderate automatic activation of battery cell balancing every 10 days to ensure full battery charge and optimal lifespan.
• Regularly check all cable connections for tightness and corrosion.
• Mantingueu el carregador net i lliure de pols i residus.

6. Solució De Problemes

The VOTRONIC charger is equipped with multiple protection features to ensure safe operation. If the charger is not functioning as expected, consider the following:

• Indicació de no càrrega:
  • Check if the charger is properly connected to the mains power supply.
  • Verify battery connections are secure and correctly polarized.
  • Inspect fuses (Sich. 1 and Sich. 2) for continuity.
• Protecció de sobrecàrrega: The charger is protected against overload. If an overload occurs, the charging current will be reduced or temporarily interrupted.
• Protecció contra el sobreescalfament: The device is protected against overheating. If the internal temperature becomes too high, the charging current will be reduced or charging will stop until the temperature returns to a safe level.
• Overvoltage Protecció: Evita els danys causats per un volum excessiutage.
• Protecció contra curtcircuits: Protects against damage from short circuits at the output.
• Protecció de polaritat inversa: Prevents damage if battery connections are reversed.
• Battery Discharge Protection: Prevents the battery from discharging back through the charger.
• LiFePO4 Battery Not Charging: Ensure the temperature sensor is correctly connected to the negative pole of the LiFePO4 battery. The device will not operate with LiFePO4 batteries without it.

If problems persist, consult a qualified technician or contact VOTRONIC customer support.
