第四章 故障处理
第四章 故障处理
本章介绍系统告警时应采取的措施以及对电源系统的日常维护。维护电源设备时，要求维护人员必须充分掌握该电源系
统相关知识。

注意
1．在进行电源设备维护工作的时候，必须要遵守安全规定。
2．插框内部操作必须由接受过培训的有足够电源系统方面知识的人员执行。
4.1 监控模块告警处理
监控模块将告警类型分为四个级别：紧急告警，重要告警，一般告警，不告警。
紧急告警，重要告警：该类型告警发生后，严重影响电源系统的工作性能，无论在任何时间发生，都要求用户立刻采取
措施进行处理。系统点亮告警显示灯，同时产生声音告警。
一般告警：该类型告警发生后，电源系统能暂时维持正常的直流输出，若是在值班时间发生则要求立刻采取措施进行处
理，倘若不是在值班时间发生，则要求值班时间开始时处理。系统仅点亮告警指示灯。
不告警：此类告警条目被用户设置成不告警，则允许在产生此类条目描述状态下，系统正常运行，不产生任何声光指示。
若在使用过程中出现不需要的告警，可以按照以下方法进行设置。
以“模块丢失”告警为例：
对于 M830B 监控：依次进入“主菜单参数设置告警参数清模块丢失告警”
，在此子菜单中，可以选择“是”来清
除该告警。
对于 M530B 监控：依次进入：
“主菜单参数设置告警参数告警控制清空”
，在此子菜单中，可以选择“模块丢
失”来清除该告警。对电源系统常见告警的处理方法见表4-1。
表4-1 常见告警处理方法
序号
告警名称
1
交流停电
2
交流过压
处理方法
停电时间不长时，直流供电由电池负担。如果停电原因不明或时间过长，就需要启动油机发电。建议油机
发电机启动至少 5 分钟后，再切换给电源系统供电，以减小油机启动过渡过程可能对电源设备造成的影响
设定值是否过低，如果过低应更改。
一般的过电压不影响系统工作，当市电电压大于 305V 时，整流模块将停止工作。因此对于长期过压的供
电网络，需与相关电力网络维护人员协商，改善电网
设定值是否过高，如果过高应更改。
3
交流欠压
若市电电压低于 176V 时，整流模块将限功率输出，低于 80V 将停止工作。因此对于长期欠压的供电网络，
需与相关电力网络维护人员协商，对电网作改善
4
防雷器故障
5
直流过压告警
检查防雷器情况，如防雷器损坏，请更换
1．检查直流输出电压和监控模块“直流过压告警”设定值，若设定值不合理请更改。
2．找出引起过压告警的整流模块。在确保蓄电池能正常供电的情况下，拔出所有整流模块，然后，逐一
插入整流模块，当某一模块接通时，系统再次出现过压告警，则该模块过压，请更换
1．检查直流输出电压和监控模块“直流欠压告警”设定值，若设定值不合理请更改。
2．检查市电是否停电，如停电，断开部分负载以延长整个电源系统的工作时间
6
直流欠压告警
3．检查是否有整流模块退出工作，即无输出电流，如有请更换该模块
4．检查负载总电流。如果浮充时负载总电流超过整流模块总输出电流，则需切除部分负载，或增加整流
模块，使整流模块的总电流超过负载总电流 120％，且至少有 1 个整流模块冗余备份
7
负载支路断
8
电池保护
检查该支路空开是否断开（检查空开手柄位置，或测量溶丝两端电压，电压接近 0V 则熔丝正常）。如果
断开，查找原因并排除故障。否则说明告警回路故障，请联系维谛
1．检查市电是否停电，电池电压下降到“电池保护电压”设定值以下或放电时间达到“电池保护时间”
设定值。2．是否手动控制电池保护

处理方法
此时，整流模块面板上的红色发光二极管点亮。切断该整流模块交流输入，一段时间后再重新启动该模块。
倘若仍然告警，请更换该模块
检查市电电压是否大于整流模块交流过压点（305V）或小于整流模块交流欠压点（80V）。因此对于长期
过压或欠压的供电网络，需与相关电力网络维护人员协商，改善电网
检查整流模块的风扇是否运行。如果风扇不运行，检查风扇是否被堵住，如被堵住，请清理。如未被堵住
或清理后仍无法消除风扇故障，则更换该模块
检查该整流模块和监控模块之间通信连接是否正常。如果正常，则重新启动该模块，如果告警仍然存在，
则更换该模块
检查是否电池内部故障造成电池过热，如是，更换故障电池
检查电池房温度是否过高，如是，降低电池房温度
监控模块故障处理
监控模块故障表现：工作状态指示灯（绿色）灭，显示屏不显示（如果连接了后台系统，也可能会触发外部告警）
。
请检查系统母线电压是否正常，监控接线端子插接是否牢固，如果以上两点均正常，则表示监控模块故障，请更换新监
控模块。

Safety Precautions
To reduce the chance of accident, please read the safety precautions very carefully before operation. The
"Caution, Notice, Warning, Danger" in this book do not represent all the safety points to be observed, and are
only supplement to various safety points. Therefore, the installation and operation personnel must be strictly
trained and master the correct operations and all the safety points before actual operation.
When operating Vertiv products, the safety rules in the industry, the general safety points and special safety
instructions specified in this book must be strictly observed.
Electrical Safety
I. Hazardous voltage
Danger
Some components of the power system carry hazardous voltage in operation. Direct contact or indirect contact through
moist objects with these components will result in fatal injury.
Safety rules in the industry must be observed when installing the power system. The installation personnel must
be licensed to operate high voltage and AC power.
In operation, the installation personnel are not allowed to wear conductive objects such as watches, bracelets,
bangles, rings.
When water or moisture is found on the Subrack, turn off the power immediately. In moist environment,
precautions must be taken to keep moisture out of the power system.
"Prohibit" warning label must be attached to the switches and buttons that are not permitted to operate during
installation.
Danger
High voltage operation may cause fire and electric shock. The connection and wiring of AC cables must be in compliance
with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high
voltage operations.
II. Tools
Warning
In high voltage and AC operation, special tools must be used. No common or self-carried tools should be used.
III. Thunderstorm
Danger
Never operate on high voltage, AC, iron tower or mast in the thunderstorm.
In thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the equipment should be
well earthed in time to avoid damage by lightning strikes.
IV. ESD
Notice
The static electricity generated by the human body will damage the static sensitive elements on PCBs, such as large-scale
ICs. Before touching any plug-in board, PCB or IC chip, ESD wrist strap must be worn to prevent body static from
damaging the sensitive components. The other end of the ESD wrist strap must be well earthed.
V. Short circuit
Danger
During operation, never short the positive and negative poles of the DC distribution unit of the system or the non-grounding
pole and the earth. The power system is a constant voltage DC power equipment, short circuit will result in equipment
burning and endanger human safety.
Check carefully the polarity of the cable and connection terminal when performing DC live operations.
As the operation space in the DC distribution unit is very tight, please carefully select the operation space.
Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.
Insulated tools must be used.
In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free movement of
the human body and tool is reduced to a minimum.
VI. Dangerous energy
Warning
More than 240VA system capacity, keep away from hazardous energy and avoid bridge connection.
Battery
Danger
Before any operation on battery, read carefully the safety precautions for battery transportation and the correct battery
connection method.
Non-standard operation on the battery will cause danger. In operation, precautions should be taken to prevent
battery short circuit and overflow of electrolyte. The overflow of electrolyte will erode the metal objects and PCBs,
thus causing equipment damage and short circuit of PCBs.
Before any operation on battery, pay attention to the following points:
Remove the watch, bracelet, bangle, ring, and other metal objects on the wrist.
Use special insulated tools.
Use eye protection device, and take preventive measures.
Wear rubber gloves and apron to guard against electrolyte overflow.
In battery transportation, the electrode of the battery should always be kept facing upward. Never put the battery
upside down or slanted.
Battery installation requires reliable grounding. And battery is connected before accessing the battery protection
device.
Others
I. Sharp object
Warning
When moving equipment by hand, protective gloves should be worn to avoid injury by sharp object.
II. Cable connection
Notice
Please verify the compliance of the cable and cable label with the actual installation prior to cable connection.
III. Binding the signal lines
Notice
The signal lines should be bound separately from heavy current and high voltage lines, with binding interval of at least
150mm.

Chapter 4 Troubleshooting
This chapter describes the handling of alarms, as well as the routine maintenance of the system during system daily
operation.
The maintenance personnel must have adequate knowledge about the subrack power system.

Note
1. The maintenance must be conducted under the guidance of related safety regulations.
2. Only trained personnel with adequate knowledge about the subrack power system shall maintain the inner part of the subrack.
4.1 Controller Alarms And Fault Handling
The controller alarms are classified into three types: major alarm, observation alarm and no alarm.
Major alarm: This type of alarms have strong impacts on the system performance. Whenever these alarms are
generated, users are supposed to handle them immediately. The red major alarm indicators will be on.
Observation: When this type of alarm is raised, the system maintains normal output for a while. If the alarm occurs
during watch time, it should be handled immediately. If the alarm occurs during non- watch- time, handle it during
watch time. The yellow observation alarm indicators will be on.
No alarm: If alarms are set as ‘no alarm’ by the users, when these alarms occur, the green alarm indicators will be on
and the system works normally.
If an unnecessary alarm occurs during the operation of the controller, set it according to the following method.
Take the alarm of ‘Rect Lost’ for example:
For M830B controller: MAIN MENU —> Settings —> Alarm—>Clear Module Loss Alarm. For the submenu of "Clear",
you can select "Rect Lost" to clear corresponding alarm.
For M530B controller: MAIN MENU —> Settings —> Alarm—> Alarm Control—> Clear. For the submenu of ‘Clear’,
you can select ‘Rect Lost’ to clear corresponding alarm.
The handling methods of normal alarms are given in Table 4-1.

Handling method
If the failure does not last long, the battery will power the load. If the cause is unknown or the failure lasts
too long, a diesel generator is needed. Before using the generator power to supply the subrack power
system, it is suggested to run the generator at least five minutes to minimize the impact on the subrack
power system
Check if the AC over-voltage value is too low. If yes, change the value.
A mild over-voltage does not affect the system operation. However, the rectifiers will stop working
operation when the mains voltage is more than 305V. If the mains voltage is above the AC over-voltage
value, the mains grid should be improved
Check if the AC Under- voltage point is too high. If yes, change the value.
When the mains voltage is lower than 176V, the output power of the rectifiers will be derated. And if lower
than 80V, the rectifiers will stop working. If the mains voltage is under the AC under-voltage value, the
mains grid should be improved
Check the SPD condition. If the SPD is damaged, replace it
Check the DC over-voltage value through the controller. If the setting value is inappropriate, correct it.
Otherwise, find out the rectifier that has caused the alarm:
1. Ensure that the batteries can operate normally.
2. Switch off the AC input of all rectifiers.
3. Power on the rectifiers one by one.
4. If the over-voltage protection is triggered when a certain rectifier is powered on, that rectifier is the
faulty one. Replace it

Handling method
1. Check if the alarm is caused by mains failure, if yes, disconnect some loads to prolong the operation of
the whole system.
2. Check the DC under-voltage value set through the controller. If the set value is inappropriate, correct it.
3. Check if any rectifier is inoperative, or has no output current. If yes, replace it.
4. Check if the total load current exceeds the total rectifier current during float charge. If yes, disconnect
some loads or add more rectifiers to make the total rectifier current bigger than 120% of the total load
current with one redundant rectifier.
Check if the corresponding MCB is switched off. If the MCB is open, find out the fault and remove it.
Otherwise, the alarm circuit is faulty. Please contact Vertiv.
1. Check if there is mains failure, and the battery voltage is lower than the value of ‘LVD2’.
2. Check whether the battery is disconnected from the system manually.
The rectifier with the fault indicator (red) on is faulty.
Power off the rectifier, and then power it on after a while. If the alarm persists, replace the rectifier.
Check if the mains voltage is above 305V or under 80V. If the mains voltage is under the AC
under-voltage value or above the AC over-voltage value, the mains grid should be improved.
Pull out the rectifier to check if the fan is obstructed. If yes, clean it and push the rectifier back. If the fan
is not obstructed or if the fault persists after cleaning, replace the rectifier.
Check if the communication cable is connected properly between rectifier and controller. If yes, restart
the rectifier. If the alarm persists, replace the rectifier.
Check if the temperature of the temperature sensor is too high. If yes, find the causes and cool down the
battery compartment.

Description
The output voltage can rise slowly when the rectifier start up. The walk in time is
configurable through the controller.
Rectifier fan speed can be set to auto or full speed.
The rectifier provides over-voltage hardware and software protection. The
hardware protection point is 59.5V ± 0.5V, and it requires manual resetting to
restore operation. The software protection point is between 56V and 59V (0.5V
above output voltage, 58.5V by default), and can be set through the controller
There are two software protection modes, which can be selected through the
software at the host:
1. Lock out at the first over-voltage
Once the output voltage reaches protection point, the rectifier will shut off and hold
that state. It requires manual resetting to restore the operation
2. Lock out at the second over-voltage
When the output voltage reaches the software protection point, the rectifier will
shutdown, and restart automatically after 5 seconds. If the over-voltage happens
again within a set time (default: 5min. Configurable through controller), the rectifier
will shut off and hold that state. It requires manual resetting to restore the
operation
Manual resetting: Resetting can be done manually through the controller, or by
removing the rectifier from system
The rectifier can start in -40°C;
For R48 3000e3 module:
Below 45°C, the rectifier with full power (3000 W) output.
From 45°C ~55°C, the rectifier with linearly derating to 2900W.
From 55°C ~65°C, the rectifier with linearly derating to 2250W.
From 65°C ~70°C, the rectifier with linearly derating to 0W.
For R48 3500e3 module:
Below 45°C, the rectifier with full power (3500 W) output.
From 45°C ~55°C, the rectifier with linearly derating to 3380W.
From 55°C ~65°C, the rectifier with linearly derating to 2625W.
From 65°C ~70°C, the rectifier with linearly derating to 0W.
