Note:
In high summer and in case of a high solar radiation, we recommend leaving
the switch in its „ON“ position. Thus, you will achieve the maximum possible runtime
of the pump.
5.2 Timer operation:
The accumulator station may be operated
with the timer function via the press
switch “Timer On”, “Timer Off”. The functi-
on is activated if the switch is pressed.
Every hour, the pump will work for approx.
10 minutes.
Note: This function shall particularly be
used in case of weak solar radiation or for
a longer overshoot time at darkness.
6. Short Circuit Protection
The accumulator station is equipped with a short circuit protection in order to prevent
any damage of the electronics by a short circuit at the pump. As soon as the connec-
tion of the pump is affected by a short circuit, the state of charge indicator will flash
alternately red and green. In this case, please check the pump for function (e.g.
directly supply the pump via the solar module) and check all plug-in connections for
tightness.
7. LED Indicator Lights
G-Normal, R-Low:
LED is lit up green when the accumulator is sufficiently charged in order to supply the
pump with energy. LED is lit up red if the accumulator is discharged. The LEDs are
not lit up when the pump is switched-off.
Charge:
LED is lit up yellow as soon as the accumulator is charged via the solar module LED
is also lit up in switched-off condition.
8. Exchange of the accumulator
We recommend to exchange the accumulator approx. every 2 years. A new identical
in construction accumulator is available from the manufacturer or dealer.
Proceed as follows if you want to exchange the accumulator:
1. Set the switch into the position „OFF“ and unplug the module and the water pump
from the accumulator station.
2. Turn the accumulator station upside down and loosen the screws on the bottom
frame of the accumulator box and carefully remove the cover.
3. Unplug both cables from the accumulator (see picture above). Please memorize
the color of the cables for the
positive pole (brown)
and
negative pole (blue).
4. Remove the accumulator from the housing and insert the new identical in con-
struction accumulator.
5. Reattach the cable lugs on the poles of the accumulator with correct polarity.
Cable color for the positive pole (brown) and negative pole (blue).
6. Close the housing in reverse order.
Note:
Please only use an identical in construction accumulator with identical voltage
and capacity.
Note:
The old accumulator has to be disposed of in an environmentally sound way.
For this purpose, please contact you local authorities, public collection points or your
dealer.
9. Storing throughout the winter
Completely charge the rechargeable battery
in the battery box. Use a sunny day to do this
and disconnect the battery box.
After charging disconnect the cable from one
terminal of the rechargeable battery.
To do this open the housing as described in
Section 8. The battery box should only be sto-
red throughout the winter in a fully charged
condition and in a frost free room.
10. Troubleshooting
LED does not light green in spite of solar radiation but the yellow LED is lit up.
1. The accumulator has not yet been charged sufficiently and the restart threshold is
not reached. The charging process may take several hours in case of insufficient
solar radiation.
2. Accumulator is exhausted! The accumulator should be exchanged approx. every
2 years. Please see item 8 of this instruction.
The LED is not illuminated green. In spite of solar radiation when switching-off
and on again of the switch On/Off , the pump starts to work and the green LED
is illuminated.
1. The accumulator has not yet reached its restart threshold. The electronics is reset
after the deactivation and activation of the system and the system starts to work
without waiting for the restart threshold. This is a normal process and does not
indicate any defect.
LED does not light up green in spite of solar radiation. When the switch
On/Off is switched-off and –on, the pump starts working and the green LED is
lit up.
1. The accumulator has not yet reached its re-start threshold. After the system is
switched-off and –on, the electronics is reset and the system starts running wit-
hout waiting for the re-start threshold. This is a absolutely normal process and
does not constitute a defect or failure.
LED flashes alternately red and green.
1. There is a short circuit at the output. Please check the pump and all plug-in con-
nections (particularly those of the LED lighting) for tightness.
2. Please check the cables for damages or bites by animals.
