red LED for indicating major and critical alarms. It also provides a drive output for alarm LED on a system cabinet.
The controller LCD can display theAC parameters, DC parameters, rectifier and battery parameters, operating status,
alarm status, settings, and control parameters.

4 Chapter 1 Introduction
LCU+ Series Controller User Manual
1.3.3 Communication Functions
The controller can communicate with the host computer in three modes: RS232, Modem, and Ethernet (WEB and
SNMP). It can communicate with the rectifiers in CAN-bus mode.
1.3.4 Alarm Functions
When the DC power system is in alarm status, the controller generates an alarm automatically and reports the alarm
to higher level controller according to actual requirements. The controller records the history alarm and a user can
query history alarm through the controller.
The alarm contents include communication failure, SPD fault, DC over/under voltage, load disconnection, battery
disconnection, BLVD, battery/ambient temperature abnormal, and rectifier alarm. The controller has four different
alarm categories.
1. CA, Critical Alarm
2. MA, Major Alarm
3. OA, Observation Alarm
4. None
User can set the alarm category for each alarm. User can also block all outgoing alarms from reporting to remote
computer and affecting any relay. This function can be programmed to reset automatically after 24 hours. When
outgoing alarms are blocked, an ‘Outgoing Alarms Blocked’ alarm is generated.
1.3.5 Battery Management Functions:
Battery test
The purpose of a battery test is to check the condition of the battery. This test discharges the battery and monitors
battery voltage and current.
During a battery test, the controller reduces rectifier output to a predefined value and the battery supplies the load
and begins to discharge. The controller monitors the battery and saves the result in a battery test log.
The controller has two separate battery tests: full load current test and stable current test.
Below are the requirements of the full load current test and stable current test.
The test can be programmed to start under the following conditions.
1. Manual start
2. Cyclic start after a predefined time schedule
Starting a full load battery test or stable current is determined by the discharge current parameter of the stable current
test, as illustrated in Figure 1-2.
Figure 1-2 The Principle of Battery Test
Battery boost charge
When the batteries have been discharged, the controller can raise system voltage to recharge the batteries quicker,
as illustrated in Figure 1-3. The boost charge function can also be used to equalize the difference between the
different battery blocks/cells.

Chapter 1 Introduction 5
LCU+ Series Controller User Manual
Figure 1-3 The Principle of Battery Boost Charge
The boost charge function can be programmed to start under the following conditions.
1. Automatic start after Commercial AC Fault (programmed to start after low battery capacity or high battery charging
current is detected) or Battery Test
2. Manual start
3. Cyclic start after a predefined time schedule
Temperature compensated battery charge
In order to extend battery life, the controller can automatically adjust system voltage as battery ambient temperature
changes. Battery temperature compensated charging is a function that lowers system voltage when battery
temperature increases and raises system voltage when battery temperature decreases.
System voltage follows the characteristics as shown in Figure 1-4.
Figure 1-4 The Principle of Temperature Compensation
Battery current limitation
The controller can limit the current to the batteries by adjusting the current limit of the rectifiers. If battery current
exceeds the alarm setting of Battery Over Current, a Battery Over Current alarm is issued.
Battery prediction
The controller can calculate the remaining capacity and the remaining time of the battery while charging or
discharging.
1.3.6 Low Voltage Disconnect
The controller can disconnect the load or battery in case of under voltage or after a predefined time from when a
Commercial AC Fault occurs, in order to prevent the batteries from deep discharge. Deep discharge can result in
permanently damaged batteries.
The load or battery can be disconnected through the two internal LVD drive outputs. The features of the LVD function
are:
The controller can manage a maximum of 2 LVDs, which are internal LVD drive outputs. The controller
disconnects these LVDs during an under voltage condition. The disconnection level for each LVD can be set

6 Chapter 1 Introduction
LCU+ Series Controller User Manual
individually. There is one reconnection level for all LVDs. These LVDs can be used for load disconnection
and/or battery disconnection.
LVD Disconnection Setting Precautions
(1) The disconnection level for load contactor should be set higher than the battery contactor so that the load
contactor can always be disconnected before the battery contactor.
(2) Maximum 1 LVD is used for battery disconnection to protect from the large current difference between
batteries (using the internal LVD2 of the controller is suggested). When Commercial AC returns, the batteries
can be close to complete discharge and the voltage difference can generate a large current. Therefore, the
current of rectifiers should be limited before the battery reconnection.
The controller can individually disable LVD1 and LVD2, preventing the contactor from opening during an LVD
condition.
The controller can reconnect the LVDs when the Commercial AC Fault alarm is inactive and system voltage is
higher than the reconnection level.
An LVD alarm is issued when the controller automatically or a User through the controller manually activates an
LVD. An LVD Detection Fault alarm is also issued when the controller detects the auxiliary input status is not
identical with the LVD operation.

Note:
1. The alarm levels of temperature sensor disconnected alarm and temperature sensor failure alarm, and the
corresponding relay output cannot be set through the LCD. The alarm levels of these two alarms and the
corresponding relay are the same with those of the high temperature alarm setting.
2. If the analog alarm has two levels of alarm thresholds, and if these two alarm thresholds are set to the same value,
then the second level will be cancelled and the first level of the alarm will be displayed in LCD. For example: If the
alarm threshold of ‘high temperature 1’ is set to the same with the threshold of ‘high temperature 2’, and if this
threshold is set to 40 deg C, then when the temperature exceeds 40 deg C, the system will only issue ‘high
temperature 1 alarm’, and will not issue the ‘high temperature 2 alarm’.
In the alarm level setting submenu, you can also set the output relay no. for the corresponding alarm.
Alarm control menu
For the submenu of ‘AlmVoice’ of alarm control menu, you can set it to ‘Open’(audible alarm is enabled) or ‘Close’ (no
audible alarm), and you can also set the time of audible alarm and the time can be ‘3min’, ‘10min’, ‘1h’ and ‘4h’.
For the submenu of ‘Block Alarm’, you can set ‘Y’ or ‘N’ to select whether the alarm should be blocked or not.
For the submenu of ‘Clear’, you can select ‘History’, ‘ECOFail’, ‘Maintain’, ‘ShortTest’, ‘TestFail’ ,’Rect Lost’ ‘Rect
Commb’and ‘Rect Not respond’ to clear corresponding alarm.
