1. internal fault has been detected and the charger must be brought to a qualified service depot Other Indications Indication Explanation and Solution AC On LED Lit Charger has detected a condition that does not allow it to charge Charger won t start charging e Confirm battery connections are good e The nominal voltage for a lead acid battery is 2 V per cell For example a 48V battery will have 48 2 24 cells e If the battery voltage is greater than 2 5V per cell the charger will not start charging e If the battery voltage is less than 0 5V per cell the charger will not start e For software revisions 0 81 or lower the charger will not start charging if the battery voltage is less than 1V per cell Refer to the lower right hand corner of the back of the Product Manual to determine the software revision e Check for any fault codes that might be set and refer to the descriptions above e A fully charged battery will draw very little current but will not show 100 charged immediately The charger will change to Absorption mode in under 5 minutes once the conditions for the end of bulk charge have been met The 80 LED will illuminate at this time During the final phase of charging the battery will only accept a very small current the charger is unable to accelerate this portion of the charge cycle without damaging the battery Excessive Overcharging or high battery temperature These symptoms are unlikely to2.

6. t or an internal fault has been detected in the charger This fault will nearly 0 0 always be set within the first 30 seconds of operation If it occurs after the charger has started charging normally be sure to make a note of it e Try to clear the fault by unplugging AC power waiting 30 seconds and reconnecting the AC e Check all battery connections Look for a high resistance connection The most likely reason for this fault is a fault in the battery such as a bad battery connection an open cell or insufficient water e This fault will occur if an internal fuse inside the charger blows If the green wire is shorted to ground even momentarily this fuse will blow To check the fuse measure with an ohmmeter between the green and red wires with the AC disconnected If a short circuit is not measured the fuse has blown Return unit to a service depot to have this fuse replaced e For software revision 0 81 or older this fault may indicate that the input or output voltage went out of range Check input and output connections before returning the unit to a service depot Charger may need to be brought to a service depot to have its software upgraded Refer to the lower right hand corner on the back of the Product Manual to determine the software revision e If this fault occurs after battery charging has started confirm that AC power was not interrupted and that all battery connections are good e If all battery connections are good an
