MODE OF OPERATION

The GENIE is a high current (minimum 37 amps) Alternator charging system with the sophisticated means of electronically controlling the output charging voltage. This provides the capability to fully recharge batteries which are under charged. All functions of the GENIE are controlled by a RISC micro controller employing the latest state of the art technology. Since the various types of batteries require a different charging voltage it is important that the unit is set correctly for the type of battery being used. On initial switch (when the ignition is swiched on) on the GENIE measures the voltage of up to three sensed batteries and calculates if Boost charging is required. Boost control will be selected if any battery sensed battery voltage is below 12.6 volts, if Boost charging is required the GENIE control unit and will a) display the battery which has been selected as master and b) increase the Alternator output voltage in incremental steps with respect to time from the normal Float voltage of 13.8 volts to a maximum determined by the selected battery type. Under certain conditions i.e. low Alternator r.p.m.the voltages mentioned above will not be obtained and under these conditions the output voltage will be maximum up to the pre-set levels. The initial ramp is 3 minutes to the maximum Boost voltage target. Each boost cycle is maintained for a period of 18 minutes and will be indicated by a Yellow light. Under normal charging conditions only these lights will be illuminated. If the Red alarm light is the only light illuminated it may indicate a fault condition and should be investigated. How ever the Red light in combination with either the Yellow & Green is not necessarily a fault condition. After each Boost charge period the GENIE will revert to Float charge mode whereby the output of the Alternator will be set to approximately 13.8 volts (27.6 volts). When the GENIE reverts to Float Charge the Yellow light will be extinguished and only the Green light will be illuminated. As in the previous instance the Red alarm light should not be on. The GENIE will remain in the Float mode for 3 minutes allowing the Batteries to rest. After the rest period the GENIE will again switch to Boost/Equalisation charge. This cycle of Boost- Float charging will continue for a total of 5 cycles, after 5 full boost charge cycles the charging voltage is then reduced on each subsequent Boost charge cycle (charge reduction depends on the batery type selected) for a further 3 cycles to equalise the battery charge. After the final 3 equalisation charge cycles the GENIE will switch to extended Float mode for 15 minutes and again only the Green light will be illuminated. After this extended rest period the unit continually scans the battery banks for a low voltage reading, if any battery bank is below 12.6 volts a further boost cycle will be initiated or the unit will continue to control at the float voltage setting whilst checking the battery states.

GENIE is being used on multi battery installations we recommend that the X-SPLIT or X-PORT is used to split the charge to the various batteries. This eliminates the need to drive the output of the alternator higher in order to achieve the required charging voltage level resulting in a more efficient charging system. The versions /BS have been designed especially for use with battery sensed alternators such as the GENIE.
