7. Battery
7.1. Substituting the battery
1. Remove the battery from its retainers;
2. Remove the cables from the battery terminals;
3. Slide out the battery;
4. Mount the battery following the above instructions in reserve order, fixing in place and connecting it correctly.
Before assembly check the battery for correct mechanical condition.
Fix the pole terminals safely to the respective end poles + and - of the battery. This is a permanent
connection and shall not be used for continuous changes.
Check the electrolyte level of the battery. If not all cells have equal electrolyte level or if the electrolyte is not
visible, refill distilled water (DIN 43530) up to shortly above plate level.
Do not refill up to max. level mark!
After recharging (according to charging condition) cleaned water may be refilled up to the maximum filling
mark. The battery is ready for operation.
7.2. General Rules and Advice for Operation
Above all, the battery manufacturer's directions and instructions are applicable.
Modern sulphuric acid batteries require little maintenance and are easy to maintain. The working life of the
battery depends mainly on the manner of application and maintenance. To ensure longest possible working
life, observe the following rules:
The indicator gives the battery condition indication by means of a series of 5 green LED and one red LED.
When the battery is charged, the first 4 green LED are on and, with the progressive discharging of the
battery, they switch off one after the other, in proportion to the residual charge of the battery, until the residual
charge value reached is such that the red LED lights up, signalling in this way that the battery is flat.
Hour counter
In the middle of the instrument dial there is a liquid crystals alpha-numerical display
which informs the operator about the working hours carried out.
Alarms
The same display used for the hour counter works also as the indicator of the alarm
condition, by displaying a code which corresponds to the kind of alarm signalled. In
order to draw the attention of the operator, the red LED begins flashing
Do not retain discharged batteries. Recharge as soon as possible.
−
Avoid heavy discharge of more of 80% of nominal capacity. The acidity should not be lower than 1,13 kg/l .
−
Heavy discharges reduce capacity and working life.
−
The most favourable operating temperature is between + 25°C and + 55°C. Do not exceed the electrolyte
−
temperature of + 55°C.
Expect a temperature increase of approx. 10° up to 12 K (°)during charging.
−
Interrupt charging before having exceeded the temperature limit of 55°C.
−
At temperatures of more than 40°C more distilled water will evaporate. Control the acid level more often.
−
Heavy duty and winter temperatures require a daily charging of the battery, even if less than 80% of the
−
nominal capacity have been consumed.
Always keep the battery clean and dry and protect against soiling.
−
Thoroughly grease the pole terminals (pole screws)
−
Only refill distilled water according to DIN 43530.
−
For charging, only use charging devices which are suited for the battery size (capacity) and charging times.
−
Before charging, remove the battery covers respectively open the battery storage cap.
−
The ventilation holes of the fillers must be free to allow battery gasses to escape.
−
Always connect the charging device with correct poles, i.e. plus to plus, minus to minus.
−
Repairs on the battery and charging device should only be executed by trained and competent personnel.
−
After having completed the charging process the stacker has to remain in a ventilated room until all
−
gasses have safely escaped. Avoid handling the electric installation during charging and in the
subsequent non-working time.
