Studer Innotec RCC-03, RCC-02 user manual Absorption phase, Equalization phase

Studer Innotec

Absorption phase {1451}

During this phase, the battery accumulates the final percentages of the energy it is storing. This phase is carried out with a constant voltage.

Authorised absorption {1155}

This configuration determines whether or not the absorption phase is used. If this phase is deactivated, the charger goes directly to the authorised phase that follows it.

Absorption voltage {1156}

Use this configuration to adjust the voltage that is used for the absorption phase.

Duration of absorption {1157}

Use this configuration to adjust the duration of the absorption. The absorption phase starts once the set voltage {1156} is reached. When the duration has run out, the charger automatically goes to the authorised phase that follows it.

Completion of absorption released by the current {1158}

The absorption phase may be interrupted if the battery charge current automatically passes below a certain threshold. This may be used in order to limit the duration of the operation of a generator while there is an acceptable battery charge.

During the absorption phase, as a matter of fact, the charge current reduces progressively. If the bulk charge has been carried out with a current correct for the battery, it is not necessary to adhere to a fixed duration to end the charging.

Current at end of absorption {1159}

Set the current value below which the absorption phase is considered to be at an end. When the current of the charger goes below this value, the next step starts.

Equalization phase {1452}

Certain types of battery require equalization in order to avoid the stratification of water and acid that they contain. Use the configurations below in order to adjust the usage conditions for this charge phase.

During an equalization phase, a large quantity of gas is released that is highly explosive (hydrogen). Ensure that you adhere to the battery manufacturer’s instructions for this function. In all cases, ensure that there is sufficient ventilation around the batteries.

During the equalization phase, the water of the battery is separated into gases (hydrogen and oxygen) and this action serves to decrease the level of liquid in the batteries. Check their level regularly.

Start equalization {1162}

Use this configuration to force the start of an equalization phase.

It is only possible to force an equalization phase if the equalization is authorised. Once the phase has started, prohibiting the phase does not stop the equalization. To stop the equalization, use Force passage to maintenance (floating) or Force new cycle.

Authorised equalization {1163}

This configuration determines whether or not the equalization may be used on the installation.
