If this instruction manual is not followed and power consumption is too high, or if
there is a short circuit in an appliance the circuit breaker in the electronic load
controller will trip. This will stop the electric current. If this occurs, check for possible
causes and rectify. Reset the switch on the circuit breaker to the 'on' position.
3. Voltage is 220V under zero-load conditions but falls when a load is applied.
Either a capacitor in the control box has been damaged or excessive load has been
applied. Reduce the load consumption to see if voltage stabilizes and if not have the
control box examined by a competent electrician.
4. Testing in the stream showed that PowerPal was capable of producing the rated
output power (1000W or 2000W, depending on model). However, after running
the electrical cable to the house this output power was found to be less.
Due to resistance from the cable, long cable runs will result in a small loss of output
power. Power loss over a 100m cable run is approximately 10W. For log wire runs it
is possible to install a 4.75~10µf capacitor at the load end or otherwise to increase the
cable diameter.
5. Power output has been falling recently.
Falling output suggests that the turbine is rotating more slowly than usual. Make sure
that the enough water is entering the forebay and ensure that the source river is
adequate for the flow being consumed. Otherwise, check the forebay and penstock
filter and clean if necessary. There may be soft organic debris such as rotten leaves
restricting the spear valve. Try running the valve completely closed and completely
open one or two cycles. This may clear the valve of any foreign material and open it
up to full power again. If that happens, then you should go to the forebay and be sure
that it is clean, and eliminate the cause that allowed the foreign material into the
pipeline in the first place. You can also check that the runner is free of leaves and
other debris and that the turbine bearing has enough grease. Under certain conditions
the generator may lose magnetism and result in loss of power. Its main winding may
be re-magnetized by applying a 3V DC power source and energizing for approx-
imately 30 seconds.
6. On starting, the control panel shows 220-240 volts and zero amps. The circuit
breaker has been turned "on" with the user load "off." No power goes to the
ballast resistor.
Check the voltage at the right side of the transformer, it should be 220-240 volts.
Check voltage at the left side of the transformer, it should be 18-25 volts. If not, the
transformer is faulty. If yes, check the voltage at the terminals at the top of the circuit
board. This should be 18-25 volts. Check the voltage at the terminals at the bottom of
the circuit board. This should be AC, low voltage. If there is 18-25 volts at the top of
the circuit board and no voltage at the bottom of the circuit board, then something in
the circuit board is faulty. If that is the case, try adjusting the potentiometer as
follows:
