Introduction
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.

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 LCU+ Series Controller

Introduction
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.

Limit: set the charging current limit. This is the maximum charging current that should be allowed into the battery at any time, as regards to the nominal capacity of the battery. For example, a value of 0.150C10 means that the charging current is limited to 15% of the battery’s nominal capacity. Over: set the over boost charging current. This is the charging current, as regards to the nominal capacity of the battery, at which an over current alarm will be initiated if this current is reached. For example, a value of 0.300C10 means that when the charging current reaches 30% of the battery’s nominal capacity, an alarm will be extended. AutoBoost: An Automatic Boost is started when one of the following conditions is reached. -Enable: Use this submenu to enable or disable auto boost charging. -Curr: This is the battery discharge current, as regards to the nominal capacity of the battery, above which an Automatic Boost is started, when the Automatic Boost function is enabled. For example, a value of 0.060C10 means that an Automatic Boost is started if the battery current is greater than 6% of the battery’s nominal capacity. -Cap: This is the remaining battery capacity under which (less than) an Automatic Boost is started when the Automatic Boost function is enabled. CycBoost -Enable: Use this submenu to enable or disable cyclic boost charging. -Period: Use this submenu to set cyclic boost charging period. This is the interval, in hours, between the boost cycles. -Time: Use this submenu to set cyclic boost charging time. This is the duration of each cycle for the Cyclic Boost when this function is enabled. Const Boost -Curr: Use this submenu to set constant boost charging current. -Time: Use this submenu to set constant boost charging time. BoostLimitTime: Use this submenu to set boost charging time limit beyond which boost charge will be stopped. Move cursor to ‘Test’, you can configure the following parameters: End Test: A Battery Test is interrupted when one of the following conditions is reached. -Volt: This is the ‘end of test voltage level’ for each battery test. -Time: This is the maximum duration, in minutes, for each battery test. -Cap: This is the remaining battery capacity, as regards to the nominal capacity of the battery, at which a Battery Test will be interrupted. For example, a value of 0.700C10 means that when the charging current reaches 70% of the battery’s nominal capacity, the battery test is interrupted. Cyc Test: Displays whether the time (on specific dates) battery test function is enabled (Y) or not (N). During a Timed Battery Test, the output voltage of the rectifiers is reduced so that the batteries power the load. If the batteries fail, the rectifiers power the load. Short Test: A short test is a short duration battery discharge test used to verify that parallel batteries are discharging equally. If the discharge current difference between the two batteries exceeds a preset level (default is 10 A), a Short Test Fault alarm is generated. -Enable: Displays whether the short (at specific intervals) battery test function is enabled (Y) or not (N). -Alarm: Displays the battery current difference at which an alarm will be extended. -Time: Displays the interval, in hours, between short battery tests. -Duration: Displays the duration, in minutes, of each short battery test. ConCurr Test: A Constant Current test is a battery discharge test done at constant current. The controller will automatically adjust the rectifiers to maintain the battery discharge current at the preset value. -Enable: Displays whether the constant current battery test function is enabled (Y) or not (N). -Current: Displays the stable test current. Move cursor to ‘TEMP COMP’, you can configure the following parameters: Center Temp: Displays the temperature, in °C, at which the system operates at normal voltage levels.
