Table 8.7 shows the procedure used to change manually from protective charge to floating 
charge. 
This operation does not apply to shared battery systems. 

(1)  An MSE battery normally operate in floating charge mode. 

(2) To prevent the battery temperature from rising, the mode changes automatically to 

protective charge mode when a "BATT FAULT1" (BATTERY OVER TEMP.) warning 
occurs. 

(3)  In protective charge mode, the battery is automatically charged at a voltage about 5% 

lower than normal (floating) charge when the battery temperature has risen above the 
rated value, in order to prevent deterioration caused by excessive charging at high 
temperatures. 

(4) After a set amount of time has elapsed (about 6 hours), if the "BATT FAULT1" 

(BATTERY OVER TEMP.) warning message has disappeared, the mode will 
automatically change back to floating charge. As a result, it will not normally be 
necessary to change the mode manually as described below.
