Chapter 6 Maintenance and repair

6.1 Daily use This equipment should be used in a clean, airy room.

When used with multiple power should maximize the positive power

shelf space, where conditions permit, it is best to install air

conditioning or exhaust fans and other equipment.

Each rectifier during system installation parameters have been

adjusted, generally without further adjustment.

Need to prepare to run the daily operation of the rectifier records once

a year to maintain the need for testing.

Rectifier failure can not run, the processing method, see the manual

"Troubleshooting" section.

6.2 Troubleshooting The output current limit is a working state, not a failure, usually

without treatment.

And LCD display panel lights when not lit, check the AC power is

normal, the input switch is closed, if the normal AC input, the input

switch is closed, there is still no indication and LCD indicator, the

rectifier is faulty. If the indicator with LCD correctly, you can make the

appropriate treatment of the liquid crystal display according to the

message. Treatment as shown in Table 6-1.

Table 6-1 Troubleshooting Table

Alarm Code Fault information Treatment AL AC input low Check the AC input, AC input is abnormal if indeed, there was no

AH AC input high To be treated, wait AC input is normal, the load is powered by

the battery HV Output voltage is

high Unplug the DC output plug, reboot, if still alarms, rectifiers need

repair. SC Output short Unplug the DC output plug, reboot, if normal, you need to check

circuit the load, if still alarms, rectifier needs repair CL Output current

limit Check the output voltage, if the voltage at 46V or more, do not

deal with. But need to check whether caused by abnormal load

limit, if the output voltage is too low, you should reduce the load

to protect the rectifier and load. TH Main radiator

temperature is

When determining rectifier failure, immediately turn off the AC input

rectifier switch, unplug the DC output plug, if the backup rectifiers,

rectifier put back up, and notify the nearest maintenance center ZTE

ZTE engineering department or be dealt with, not on their own

disassemble, otherwise ZTE will not be responsible.
