z Data Local Storage: the controller can provide a local storage to save real time data and alarms/events as history

z Program Update: the controller can have possibility to update the application locally and remotely z Battery Management: the controller can provide function for battery management, such as current limitation,

boost charge, battery test, and low voltage disconnection

z Power Split: The ACU+ provides the function for power split. The power system with the ACU+ can act as a slave system to share load (split output) with an existing master system that needs extension. The ACU+ does not need to communicate with the master system control unit.

z Alarm Management: the controller can provide function of active alarm list and alarm history



z Rectifier Redundancy: the controller can provide function for rectifier redundancy z Man Machine Interface: the controller provides a local user interface with a 128 * 128 dot matrix LCD or 128 * 64

dot matrix LCD, 4 buttons and 3 LEDs. The controller shall also provide a local console interface and a Web based interface

1.5.2 Communication Functions

The ACU+ can communicate with MC (Main Computer) or other devices through its 10M/100M Ethernet port. It also provides the alarm dry contacts through IB1/IB2/EIB.

Communication through 10M/100M Ethernet port

Communication cable shall be shielded cable.

Communication through RS232

RS232 communication is generally used for point-to-point communication. The communication distance shall be less than 15 meters. If ACU+ communicates through RS232, just connect ACU+ RS232 port to the RS232 port of MC.

Communication through MODEM

When ACU+ communicates through MODEM, it uses PSTN to realize long-distance monitoring. Power supply cables and communication cables shall be prepared for the communication through MODEM. MODEM communication mode accords with EEM Protocol.

Dry contacts output

The ACU+ can connect IB or EIB board, and can provide up to 13 dry contact outputs. Every dry-contact output has NC (normally closed) and NO (normally-open) contacts. Every dry-contact output shall be configured before the alarm event occurs, so that different dry-contact output can trigger different alarms. Once the alarm event occurs, the dry-contact will close or open to generate the alarm.

If the user has other intelligent equipment to be monitored by ACU+, the user can connect the dry contacts to the interface of the intelligent equipment, and control the intelligent equipment through these dry contacts.

1.5.3 Alarm Functions

The alarm events are classified into different alarm categories. Different alarm categories have different visual/audible alarm and alarm-call back activities, as shown in Table 1-1.

Figure 1-3 The Principle of Battery Compensation

Boost charge: When one of the batteries charge current exceed predefined value, that means maybe the batteries need to be recharged faster, the ACU+ can raise the system voltage for the batteries to be recharged faster. The boost charge function can also be used to equalize the difference between the different battery blocks/cells.

Battery Test: The purpose of a Battery Test is to check the condition of the battery. During a battery test the ACU+ controls the rectifiers by voltage or current and let the batteries take entire or part load. The ACU+ monitors the batteries and save the result in a battery test log. The battery test has three modes, short time test (requires two battery shunts), time test and stable current test. Battery tests can be started either manually or automatically at scheduled times for regular test of battery status. For manual battery tests as well as for cyclic battery tests, the following parameters must be set: End voltage, Test time and Battery capacity discharge limit. Battery test result is shown as follows:

Alarm shielding means: If Alarm A shields Alarm B, when Alarm A happens, Alarm B will not be reported even if the conditions of alarm B are met. For example, AC failure alarm will shield AC low voltage alarm. When AC failure happens, the alarm conditions for both AC failure alarm and AC low voltage alarm are met, and both alarms should be reported. However, since the AC failure alarm shields the AC low voltage alarm, only AC failure alarm is displayed in the alarm list.

First, select the device to which the alarm signal belongs, all the alarm signals of this device will be displayed.
