7.5 Test of output voltage
7.5.1 Float charge (U1)
Be sure that the controller is operating.
Connect load, approx. 50% of total capacity, to the system.
Check the voltage according to the battery manufactures requirements. If the batteries require other float
charging voltage, adjust the output voltage from the controller. (See product description controller)
If nothing else is required, use the following values:
7.5.2 Adjustment of float charge, U1
Output voltage is factory pre-set to: See Appendix B. The total voltage has to be in accordance to the
number of battery cells.
Please verify number of cells and the battery manufacturers requirements.
Adjust output voltage from the control unit.
Note! A sealing protects the potentiometer in the subrack. Do not break the seal.
7.5.3 Boost charging (U2) (if applicable)
Open lead-acid batteries.
Automatic boost charging - calculation of the time the battery voltage has been below certain levels.
Automatic activating of boost charging for this calculated time multiplied by a (boost) factor.
Activate boost charging from the "Set/select U1-U4" menu in the control unit.
Return to float charge manually by selecting "U1", or automatically after a pre-set time.
Sealed lead-acid batteries.
Most of the manufactures of sealed lead acid batteries do not recommend boost charging. If this type of
battery is used, the boost function should be disabled.
Boost charging figures
Observe and write down all of the boost charging figures.
