The bulk setting voltage range is 13 to 15 volts, also a 2-volt span.
To set the bulk setting to say 14.4 volts:
(14.4 – 13) / 2 * 5 = 3.5 volts – You would set the bulk potentiometer to 3.5 volts (as read with the volt/ohm
meter at the test probe location) – This will result in the bulk setting for the controller to be at exactly 14.4 volts.
Method 4:
If you are unable to use any of the above methods, then you will need to cause your batteries to be brought to
desired trip point via your wind/solar/hydro energy source. Then once they have achieved this set point, turn
the desired set point potentiometer fully counter clockwise. Wait a few seconds, and then slowly turn the same
potentiometer clockwise until the red LED changes state. You will want to check this setting as the battery
voltage is brought up and down around your set point.
You may choose to simply use the markings on the potentiometers themselves to determine the approximate set
point within +/- .075 volts. Please refer to the image on page 13 in this manual for more precise voltage
reference locations over that which may be printed on the circuit board.
Remember, the red LED is illuminated when the mosfets are conducting current, regardless of whether it is in
the solar or diversion mode. If the red LED is illuminated in the solar mode, then solar energy is being allowed
to charge the batteries. If the red LED is illuminated in the diversion mode, then battery and excess energy is
being diverted to the diversion load.
