The method of disabling BLVD is: Set “BLVD Enable” item of the monitoring module to “N”. Refer to 4.7.3LVD Parameter Description, 5.5.2Battery Management Parameters or 6.7.3Battery Settings for setting method. Notice Notice The advantage of enabling BLVD is protecting the batteries from over-discharge when the battery voltage is low. The disadvantage of enabling BLVD is that when the battery voltage drops down to a certain value, all the loads (including non- priority loads and priority loads) will be cut off due to battery disconnection.
This chapter introduces model description, composition and configuration, and features. The “system” in this manual refers to the PS48150-3B/1800 (NetSure 501 A50) (abbreviated as “NetSure 501 A50”), PS48300-3C/1800 (NetSure 501 AA0) (abbreviated as “NetSure 501 AA0”) and PS48300-3A/3200 (NetSure 701 A51) &...
