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.
