3 Functions
3.1 Alarm management function
The monitoring unit processes the real-time system data according to the parameters
set by users. When a critical fault occurs, it generates an alarm and reports it to
background PC automatically. The fault information is then recorded and stored locally.
Users can access to alarms information through the monitoring unit directly. The details
are shown in the table below:
Table 2 Alarm management function
Button Description
Alarm setting
A user can set the upper and lower limits of the system
parameters according to the real application requirements.
Alarm
management
The system has reliable and real-time alarm management
function.
Alarm mode
In case of any alarm, the monitoring unit generates audible and
visual signal to inform the maintenance personnel and reports the
alarm information to a background PC through its communication
interface. Press any key to mute the alarm sound; then the ALM
indicator keeps glowing until the fault is eliminated.
3.2 Battery management function
The monitoring unit manages storage battery charging in three modes: periodic
equalized charging mode, equalized charging mode (after power failure) and floating
charging mode.
When the mains supply is cut off, the battery supplies the powerfor load. When the
battery is discharged to a certain voltage (user can set this threshold through the
monitoring unit), an alarm will be generated.

3.3 Control Functions
The system is provided with manual /automatic Load Low Voltage Disconnect (LLVD)
functions. Users can configure the loads according to the real application requirement.
Control the power-on, power-off, the equalized charging and the float charging of the
rectifier through the control instruction of the foreground man-machine interaction
operation or through the background computer. Adjust the output voltage of the rectifier
(-42 V to -58 V, adjustable continuously) according to the user requirements.
3.4 Three-Remote Functions
• Remote information.
• Remote control.
• Remote measurement.
3.5 Man-machine interaction Functions
The LCD and keys constitute the man-machine interaction, which enables the user to
set the system operating parameters and query the related information. The operation is
convenient and reliable.
3.6 Communication Functions
RS232/RS485 communication interfaces are provided. Centralized monitoring can be
realized through other modes.
