Battery Current Limit automatically limits the battery charge current within a configured 
range (a percentage of the C10 rating of the battery) by varying the system voltage. 

Enable Battery Current Limit to prevent: 

• 

Overcharging of the batteries in under-loaded systems 

• 

Overgassing of the batteries 

BCL Engine Run Limit limits the battery charge current to a preset value, when the power 
system is powered by a standby engine/alternator during an extended AC power outage.  A 
smaller engine/alternator set can therefore be used without excessively pulling down the 
alternator voltage. 

If BCL Engine Run Limit is enabled, then: 

• 

The battery current limit process will use the Engine Run Limit as the charge parameter 

rather than Battery Current Limit, and 

• 

The User Digital Input and User Alarm number (as specified by the Engine Run Digital 

Input number) will not be available.  (The default setting is Digital Input 1.) 

Battery Test is a preventative maintenance tool that monitors the discharge capabilities to 
ensure that the condition of the battery has not deteriorated over time. 

The SM45 supervisory module temporarily reduces the output voltage of the rectifiers just 
below the bus voltage for a set duration.  The battery now supplies power to the load.  A 
battery test passes if the battery capacity remains above a predetermined level for the 
duration of the test. 

 

Equalize charges the batteries at a higher voltage after they have been fully charged to 
ensure that all individual cell voltages are the same. 

Battery manufacturers recommend that batteries be equalized periodically.  Refer to the 
battery manufacturer’s instructions, before equalizing the batteries.
