BLVD
The system has battery low voltage disconnection (BLVD) function. BLVD means when the mains fail and
batteries supply power, the controller cuts the load off when the battery voltage drops down to below 43.2V to
prevent over-discharge. The BLVD voltage is settable. Refer to ACU+ or NCU User Manual
for setting method.
The factory setting is enabling BLVD, which means that if power outage lasts for a long time or the power system
fails, there might be BLVD. Users should classify the loads and connect the priority loads to BLVD routes. For
vital loads, users can disable BLVD of these loads to insure reliability of the power supply.
The method of disabling BLVD is:
Set “BLVD Enable” item of the controller to “N”. Refer to ACU+ or NCU User Manual for setting method.
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.
The advantage of software disabling BLVD is prolonging the power supply of priority loads. The disadvantage is that
software disabling cannot prevent unwanted power failure due to misoperation or power system failure.
Others
I. Sharp object
Warning
When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object.
II. Cable connection
Notice
Please verify the compliance of the cable and cable label with the actual installation prior to cable connection.
III. Binding the signal lines
Notice
The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least
150mm.
