1.3 System Operating Principle

Fig.1-2 System Operating Principle

Chapter 1 System Outline 3

GIE 4820/3A/3.45KW Power Supply System User Manual

As shown in Fig.1-2, the power system is powered by one AC mains. AC power is first input QF1 circuit breaker and then fed into the rectifier module after EMI filtering. QF1 functions as over-current and short-circuit protection to AC power. After the combination of distribution unit, the DC output of the rectifier module is divided four branches to power to the loads. The four loads are separately controlled by circuit breakers of QF2, QF3, QF4, and QF5, and provide users ON/OFF control, over-current protection and short-circuit protection to every loads. A load power-off contactor KM1 is connected in series with the LOAD2, LOAD3, and LOAD4. The user’s battery is connected to the DC output terminal of power supply system through QF6 circuit breaker and KM2 power-off contactor, and the circuit breaker provides disconnection control, over-current and short-circuit protection to the battery.

Under normal conditions, every parameter of rectifier modules and distribution unit are all under control of the monitoring module, operating according to the pre-set parameters of user’s commands. If AC mains faults, the battery will power to the system. With the battery discharge, the terminal voltage of the battery starts descent. When the battery voltage drops to 45V (1V higher than the default load disconnection voltage), the monitoring module will report ‘DC under-voltage’ alarm signal. When battery voltage drops to 44V (1V higher than the default battery disconnection voltage), the control contactor KM1 of monitoring module acts to cut off the connection between power supply and the Load 2, Load 3, and Load 4. Then the power system just powers to the Load 1 (important load) to prolong the powering time for the important load. When battery voltage drops to battery protection voltage point (43V), the control contactor KM2 of monitoring module acts to cut off the connection between power supply and the battery and protects the battery for over-discharge. Then the power system will stop working. When the external AC mains recovers and the rectifier modules resume normal outputs, the system will recover to the normal work state. (All above monitoring data are system default values, users can reset.)

Except for battery over-discharge protection, the system is designed with battery and load over-temperature protection function: if the battery or load temperature exceeds 53℃ for continued 30 seconds, the monitoring module will control battery

or load power off unconditionally until the battery or load temperature drops down to recovery point. Battery or load over-temperature function is prohibitive under default condition, users can send command to active or inactive according to the demanding. The range of load over-temperature protection point is 50~70℃

(default is 65℃), and recovery point is fixed designed 5℃ lower than the protection point. The range of battery over-temperature protection point is 40~70℃ (default is 50℃), and recovery point is fixed designed 5℃ lower than the protection point.

The system can also collect and report all kinds of environmental parameters via monitoring unit, such as: smoke, gate magnetic, waterlogging, temperature and humidity, etc.

Fig.1-6 User Interface of the Monitoring Module

Function explanations:

1) There are two indicators (operation indicator and alarm indicator) on the panel of the monitoring module to provide the system operating state to the users. When the monitoring module is under normal operation, the operation indicator (green) is flashing regularly. When the monitoring module detects alarm in the system, the system alarm indicator (red) will be on. Otherwise it will be off.

2) The power system provides two communication ports: communication port COM and MS, used for communicating with the host computer. Communication port COM adopts RS232 or RS422 communication method, and communication port MS adopts RS232 communication method, and the baud rate is fixed at 9600. The communication port can also automatically identify whether the present communication protocol is “Communication Protocol between PSM-B9 Monitoring Module and Master/Slave Node of the Host” or “Communication Protocol between PSM-B9 Monitoring Module and the Host of Access Network”. When the host communicates with the standby communication port MS, the main communication port COM stop communicating. The communication ports of COM and MS cannot take effect at the same time. When the communication port MS of the monitoring module communicates with the host, the communication port COM is of no effect.

1.5 Monitoring Functions of the Power System

1.5.1 Function Introduction

The monitoring module of the power system is used to monitor operation status and environmental parameters of rectifier modules and distribution module. When the monitoring module detects the abnormity, it can not only send light through the panel, but also control the output of alarm dry contact according to the alarm class of the current alarm information: JK1 will close when there is a serious alarm, and JK2 will close when there is a general alarm.

The monitoring module of the power system also has the communication report function. It can communicate with the host through RS232 or RS422 mode according to the protocol defined internally by the enterprise. It can receive queries, settings, and control from the host and can report the detected status and physical parameters to the host for the convenience of centralized management.

The monitoring module of the power system also has the perfect battery management function.

1.5.2 Expanding of System Monitoring Performance

1. Communication Function between Monitoring Module and the Host

The power system provides two communication ports for communication with the host. The ports locate on the panel of the system monitoring module.

Users can write the host monitoring software oneself according to the communication protocol provided by the enterprise and realize the remote message, remote sense, and remote control by the monitoring module. Users can realize the centralized monitoring and automatic management of the power system in monitoring center via RS232 or RS422 communication lines.

Main communication functions that can be carried out between the power system and the host:

(1) Sending real time analog data from the monitoring module to the host. (2) Sending real time digital data from the monitoring module to the host. (3) Sending alarm and status information to the host. (4) Receiving control commands from the host such as on/off of rectifier modules. (5) Receiving system configuration parameters set by the host and giving feedback

of the system configuration parameters to the host.

Chapter 1 System Outline 13

GIE 4820/3A/3.45KW Power Supply System User Manual

When the communication protocol is "Communication Protocol between PSM-B9 Monitoring Module and the Host Main/Slave Node", relationship between the host and monitoring module is active/slave. All reading, setting, and control process must be initiated by the host, and the monitoring module is always in slave mode. Monitoring module cannot report data to the host actively without the correct command from the host. The communication addresses of all the monitoring modules, which communicate with the host, are set (through the dial switcher on the monitoring main-board, detailed information can refer to the Chapter 3) and make sure that the communication address of each monitoring module are not repeated.

When the communication protocol is “Communication Protocol between PSM-B9 Monitoring Module and the Access Network Host”, the communication address does not need setting. When the current alarm information, analog parameters, state information, and etc., change, the monitoring module will report corresponding information to the host actively, and the host can enquiry monitoring module information in real time.

2. Control Functions

The power system can send control signals through the monitoring module according to some inspecting values or the commands form the host.

(1) Turn on or turn off corresponding rectifier module according to rectifier on/off commands sent by the host.

(2) Turn on or turn off the power for loads or batteries according to the power on/off command and system parameters sent by the host.

(3) Control the on/off status of two digital outputs according to the control command sent by the host.

(4) Control the equalized/floating charge statuses according to the control command, control mode and system parameter sent by the host.

(5) Control the output of dry contact according to the system current alarm class. (6) Control the start/stop of the battery discharge testing according to the command

sent by the host and current system state. (7) Control over-temperature protection of battery and load according to the

command, control method, and system parameters sent by the host.

3. Detecting Function

The monitoring module of the power system is able to perform real time detection of distribution module parameters, rectifier module parameters, environmental parameters, and standby digital parameters.

(3) Environmental parameters: detecting battery temperature, ambient temperature and humidity, smoke alarm, gate magnetic switch alarm, waterlogging alarm, and distribution frame status according to the sensor installation conditions.

(4) Standby parameters: seven standby digital parameters.

4. Battery Automatic Management Function

The monitoring module of the power system has professional battery automatic management function to ensure battery groups in the system are always working under good conditions.

5. Protection Function against Loss of Power

In case of loss of power in monitoring module, the configured parameters can be maintained. If the default configuration and control mode are desired to use, restoration of default configuration command can be sent by the host.

1.5.3 Background Monitoring Parameter Table of the Power System

Two groups of batteries are parallel with DC output of rectifier module (keep the same polarity) via 63A circuit breaker, and work in FC (floating charge) or EC (equalized charge) mode. The rated input voltage of the battery is 48V with a rated volume of 50~500Ah.

Note:

1, By default, the battery group capacity is set to 100AH. If the actual battery capacity is different, the setting should be changed accordingly through the background lest the battery management should go wrong.

2These two groups of batteries actually conduct battery management through a common power off contactor and a shunt. The battery current tested by the monitoring module is actually the total current of two groups of batteries. So the battery group number should be set as one group, and the battery capacity should be set as the sum of two groups of batteries the during the monitoring module background setting.

the Power System

3.1 First Power On

Power systems have been tested strictly in the factory before delivery. After the installation of the power system , the following shall be inspected carefully before the first power on.

■ Check that the connections of AC input cables, DC output cables, and battery cables are secured, and that all the screws are not loose.

■ Check to make sure that all circuit breakers on the distribution module are off (pulled downwards).

■ Testing with a universal meter to insure that there is not any short circuit phenomenon in the AC input and the output terminals.

■ Check the connection between DC output and battery, check the numbering, line sequence and polarity. Check the firm connection of cable terminals. Check to

make sure of the correct and reliable connection of bus bar. Check again the polarity and sequence of battery connection.

After above inspections, the system can now be tested with first power on.

1. Turn on the AC power for the power system. Measure the voltage of AC input with universal meter at terminals of L, N. If the AC power supply is abnormal, check the AC power source.

2. When AC power is confirmed to be normal, close AC input circuit breaker of distribution module (push upwards). After a short delay of start-up, all operation indicators (green) on the panels of rectifier modules should be on. And the RUN indicator (green) of the monitoring module shall be flashing continuously, ALM indicators (red) should be on (the monitoring module will send out alarms since some switches are not closed).

3. Check the polarity and terminal voltage of “BATT(+)” and “BATT(-)” with a universal meter (about 53V). If it is normal, close control circuit breaker of battery branch and connect the battery into the system.

4. Close control circuit breaker of load branch, the power system will power supply to the communication load.

If all above results are normal, it means that the power system is working under normal conditions and the next step of testing can be conducted.

3.2 System Operation

After installation and testing of GIE 4820/3A/3.45KW power system, it is ready for use. It can be put into normal operation through simple power on operations when needed. Power on process is given below:

Start → System Inspection → Turn-on AC Power → Rectifier Modules Working → Cut-in Load → End

The fan may be run then stop when powers the module on for the first time, and it is normal because the fan adopts fan velocity adjusting technology. With some loads, the inner temperature of the module will increase after operation for a period of time, then the fan begin to run and it will speed up along with the increase of inner temperature to insure the normal operation of the module.

 Note:

To make sure the module cannot be damaged in some abnormal states, over-temperature protection circuit is adopted inside the module. After a period operation, the inner temperature of the module may be a little higher, turn off the module at this time and then turn on the module, the module may have no output. It is normal because the over-temperature protection circuit inside is working. 1~2 minutes later, the output of the module will recovery after the inner temperature decreases.

If the fan does not run, and it still does not start over 5 minutes with the fan alarm indicator is on, then the module may be damaged for long operation, and please contact the technical service department of our company.

3.3 System Testing

It is not necessary to test AC over-voltage and AC under-voltage alarms and protections, because they have been tested strictly in the factory.

3.3.1 Setting of Communication Address of Monitoring Module

When the communication protocol between the monitoring module and the host adopts “Master/Slave Node Communication Protocol between PSM-B9 Monitoring Module and the Host”, the communication address of the monitoring module needs setting.

The communication address of the monitoring module is set as following through the dial switcher on the monitoring main-board that locates on the position of S1 in the middle of the monitoring main board (pull out the installed monitoring module). It has eight bits, and the lower four bits are effective. ON—1, OFF—0, BIT0—low bit, BIT3--high bit, binary scale, the corresponding relationships is:

Power supply the load by the battery, cut off AC mains for above 15 minutes (±1 minute) then recover AC mains, all of the rectifier modules will be automatically in

current-limiting equalized charge state. During the current-limiting equalized charge state of the module, it is normal that its

output voltage sometimes is below 53.5V. Because the testing of battery auto-management requires strict for the system state,

it is not necessary to test battery auto-management, and the system has been tested strictly in the factory before delivery.

3.3.4 On/Off Testing of the Module

Set the control module as background control through the host, and control on/off of each module, and the corresponding module should act correctly.

Pay attention to changing the control mode to the automatic control module after the testing is finished.

3.3.5 Under-voltage Alarm and Power Off Testing

Cut off AC power, and supply power to load using batteries. Set DC under voltage threshold, load shutdown voltage, and battery shutdown voltage to higher values (to shorten the test duration). Then observe the alarm for battery under-voltage alarm, shutdown for battery and load. The monitoring module sends out the alarms for DC under voltage, load shutdown and battery shutdown one by one. Red indicators on the panel of monitoring module shall be on, and control the dry contact of external alarm sound-light alarm equipment to output superior alarm signal.

Recover the AC power, and restore the settings of under voltage threshold, load shutdown voltage, and battery shutdown voltage, then above alarms should disappear.

3.3.6 Testing of Module on Operation

Set the power system address and the number of the rectifier module correctly, insert and pull the rectifier module one by one, the background equipment should display the communication state of corresponding module correctly.

3.3.7 Alarm for Disconnection of Battery Circuit Breaker

Connect the battery to the system, then disconnect its circuit breaker. The background equipment should give alarm on the disconnection of the corresponding battery circuit breaker. The alarm will disappear when the breaker is closed.

3.3.8 Alarm for Disconnection of Load Circuit Breaker

Connect the load to the system, then disconnect its circuit breaker. The background equipment should give alarm on the disconnection of the corresponding load circuit breaker. The alarm will disappear when the breaker is closed.

3.3.9 Alarm Testing on Gate Magnetic, Smoke and Waterlogging

If sensors for gate magnetic, smoke and waterlogging have been installed, change the status of sensors. The background equipment should give the corresponding alarms.

 Note:

1) If the terminal of corresponding load and battery circuit does not connect with load or battery during testing stage, on its midair state, the alarm of circuit breaker disconnection for corresponding load or battery cannot be reported accurately.

2) Be sure that system configurations are restored to normal status after testing.

3.3.10 Viewing Operating Information

After the power is on, simple operating information can be viewed via indicators on the monitoring panel. For detailed information must be looked over through the background monitoring.

3.3.11 Canceling Battery Protection

If the user thinks it is more important to keep power supply to loads than to protect the battery, and battery protection in case of AC outage is not desired, load and battery shutdown permission state or battery shutdown permission state can be set to no-permission state via the host.

 Note:

When battery is discharged to protection value, the time for continued power supply is very short. It is impossible to obtain the long time operation of loads with battery sacrificed.

3.4 Routine Maintenance of the System

3.4.1 Inspection and Repair of Fan and Dust Mesh of the Rectifier Module

Dust will accumulate on the baffle plate after the rectifier works in dusty and windy environment for a long period. To ensure long-term reliable and smooth operation of the rectifier, it is necessary to clean the fan and baffle plate regularly.

Fan is wastage device, and it must be cleaned and replaced after it works for a certain period. Fan replacing method: first unscrew the screws on the top right corner of the fan to remove it, and then disconnect power cable. Do not touch the devices within the rectifier module with hand during the cleaning or replacement.

GIE 4820/3A/3.45KW Power Supply System User Manual

 Note:

1. Just the person who has been strictly trained professionally is capable of cleaning and replacing the fan.

2. It is recommended to clean the fan once every 6 months, and replace the fan with a new one after 3-5 years.

3.4.2 Emergent Process of the Rectifier Module

1. Internal Short-circuit of the Module

The module can be exit from the system automatically when its internal is short-circuited.

2. Output Over-voltage of the Module

After the module outputs over-voltage due to some reasons, the output of the module will be locked up. Then the AC input of the module should be cut off until the indicators are off and the power source can be turned on. If the over-voltage still exists, the module may be damaged and need replacing.

For multi-module parallel working state, if the load is light, then one module over-voltage will cause all the modules are in over-voltage state. Then it need inserting the module one by one and powers on to test the failure module. The failure module is replaced after it has been confirmed.
