Operating manual for
BAUER RAINSTAR series
TX Plus
37
6.11 BATTERY
In the factory a battery of 12 V and 6,5 ampere hours is mounted.
Charging the battery with a standard solar panel during the irrigation season is not necessary. Basically, the battery
should be charged all 6 month with a charging current of max. 2 ampere. (Please note the maintenance and
operating manual).
If the battery is connected the display shows for a short time e.g. “VERSION 4.1”, and then goes over to standard
display again.
In order to ensure a long lifespan of the dry battery of the ECOSTAR (LC-R 127R2PG 7,2 Ah/20 HR), it is
important to follow certain guidelines when storing and charging the device.
During operation of the battery on the ECOSTAR no special precautions need to be taken as the solar panel
permanently charges the battery.
1. Every new RAINSTAR irrigation machine delivered by BAUER, which is equipped with an ECOSTAR is also
equipped with a fully charged and ready to use battery.
The solar panel,however, is covered and not connected to the battery. If there is a longer period of time
between delivery and first operation the battery needs to be maintained. (see following points)
The same applies for spare part batteries and batteries which were held on stock for a longer period of time.
2. If the RAINSTAR is not in operation for a longer period of time, e.g off season, the battery should be
disconnected from the ECOSTAR and dismounted.
3. The accumulator battery should be stored fully charged, separate of conductive materials and out of the sun.
If the accumulator battery is stored in an uncharged condition for a longer period of time the full capacity
cannot be reached again after charging.
4. The optimum storage temperature lies between 0° and +25°.
Also during storage the battery underlies self-discharge and needs to be charged in the following intervals:
Storage temperature:
Interval for charging:
Less
than
+20°C 9
month
+20°C to +30°C
6 month
+30°C to +40°C
3 month
5. The humidity in the storage room needs to be low (55%+/- 30%) in order to prevent that the poles corrode.
6. A complete discharge of the battery should be prevented (deep discharge). The battery can be charged and
reach its full capacity again but a repeated deep discharge the lifespan of the battery is reduced.
7. The accumulator batteries should be kept clean. For cleaning a dry cloth can be used, if required soaked in
water or alcohol.
Under no circumstances use oil, petrol or diluents.
8. Accumulator batteries must not be disassembled as they contain acid which can cause strong chemical burns.
9. Accumulator batteries must not be hot-wired as they could be damaged.
10. Charging the battery should be done with a voltage of max. 2,0 A. If the battery is fully discharged the battery
needs approx. 7 hours until is is fully charged.
Devices which check the capacity of the battery, as well as devices with an intelligent (self-regulating) charging
function, enable an exact analysis as well as a controlled charging of the battery.
