A quality calibrated voltmeter will provide even more accurate FLEXmax 80 battery readings if an undesirable voltage drop occurs. When measuring battery voltage, ensure a good connection is made to the four wire lugs. Check the battery temperature compensation voltages if the voltages are much different than you expect from the charger setup Absorb and Float voltage settings. Use the <->and <+> soft keys to match the readings from the voltmeter (use of appropriate wire gauge will mini- mize voltage drop). When finished, press the <NEXT> soft key to view the RTS Compensation screen.

During cold weather, a battery often requires a higher recharging voltage. Lower quality inverters might not accommodate these higher voltages and can shut down during recharging, cutting off power to their loads. The FLEXmax 80 allows the user to lower the compensated voltage in the Absorb cycle so these inverters will remain operating. Also, some batteries have an absolute voltage limit that should not be exceeded and the WIDE/LMIT option allows the user to control this during recharging. WIDE allows the RTS full control over recharging; LIMIT sets the ceiling and floor voltages for the RTS.

During hot weather, the LIMIT feature set point assures recharging will continue at a high enough voltage rather than dropping too low in reaction to a higher ambient temperature. This assures the recharging voltage ad- equately charges, but should be monitored according to the battery manufacturer’s recommendations.

The RTS default compensated voltages apply if the WIDE/ LIMIT option is set to WIDE. To change these values, press the <WIDE> soft key to bring up the next screen which

allows user-determined limits. Press the <SET> soft key to adjust these values.

Press the < > soft key to choose the limit value you want to adjust. Press the < - > and < + > soft keys to adjust the chosen value(s). When finished, press the <BACK> soft key to return to the RTS Compensation screen.

*Optional OutBack RTS must be installed
