ACCESSORY BATTERY

Service instructions

For a tubular armoured drive storage battery consisting of 24 cells type 6 PZS 690 S - 48 V - Capacity 690 Ah with discharge in 5 hours.

Use

The electrical machine should never be used up to the battery complete discharge. To optimize the battery use, especially in terms of length of service, only 90% of its capacity should be allowed to run down over a 5-hour period. The machine should therefore stop operating when the fluid capacity in the cells drops to a specific weight of 1.13-1.14, that is the weight which corresponds to 90% of its capacity. If the density is not measured, the machine should be stopped at the first signs of performance drop and the battery should be recharged either immediately or, preferably, after a few hours of rest. The work shift length should be programmed taking this requirement into consideration; otherwise the battery deteriorates prematurely.

Overcharge

Batteries which are in good condition do not generally require overcharging.

Overcharging is recommended for batteries which have not been used for over 15 days, because completely run down or faulty etc.

The overcharging current should never be more than half the normal charging current for a period lasting approx. 9 hours, divided into three periods (3 hours of charging and 2 hours of rest).

Special overcharging treatments, where required, will be recommended by the technicians.

Maintenance

a)Topping up

The cell electrolyte level should be kept at approx. 1 cm above the bored surface (splash guard) which can be seen inside the cells when looking through the plug hole.

When the level drops, leaving the splash guard uncovered, distilled water must be added until the required level is reached. The electrolyte level should be topped up equally in all cells so that its density is even.

This accuracy can only be obtained by means of the “IMPIDOR” topping up device which is easy to use, not requiring any particular precision. Topping up could never be done evenly by using funnels, pipes etc., even if the operation were carried out with the utmost care.

The topping up frequency depends on the type of efforts to which the battery is subjected as well as on charging and temperature. It is, however, important to check the electrolyte level and density once a week after charging.

If topping up is required increasingly more frequently, this is due to excessive or prolonged charging. Check and calibrate the rectifier immediately.

b)Cleaning

The battery should always be kept clean and dry. This is of extreme importance to avoid oxide formation on the lifting hooks or on the battery container edges etc. as this leads to current leakage and corrosion.

Periodically clean the entire surface of the battery with a damp sponge so as to remove the film of acid which tends to deposit during charging.

If the container has a discharge hole (unfortunately not all containers have one, or can have one) it is possible to clean the surface with a water jet, thus obtaining far superior results than with a sponge.

It is not necessary to dry: since all acid traces have been removed, the cells become dry in a short time.
