Test Tools
Test Method
1
System current sharing
After each rectifier is over half load, the
output current imbalance between
rectifiers should be less than ±5%
Calculate the imbalance based on the output current
of each rectifier displayed on the controller; or the
rectifier output current displayed on each rectifier
2
Display of voltage/current
The difference between the rectifier
voltage, busbar voltage and various output
voltages displayed on the controller shall
be less than 0.1V; the difference between
the sum of the displayed currents of all
rectifiers and the sum of charge current
and total load current shall be within the
specified error range
Read the voltage and current values displayed on the
controller and rectifiers, and make judgement
according to the above standards
3
I/O indicator display
Same to working status
Multimeter
If not the same to working status, use multimeter to
check that the fuse tube of the indicator is failure
4
Parameter setting
Conduct compliance check according to
the record of the previously setting
parameters (parameter table)
Reset those parameters not in conformity with the
specified requirements. The operation method of
parameter setting can refer to the
M822E Controller
User Manual
5
Communication function
The communication between each system
unit and the controller shall be normal and
there shall be no record of frequent
communication interrupt between one
certain unit and the controller in the
historical alarm record
Query that there is no communication interruption
record
6
Alarm function
Alarm should be given out in case of fault
Check the testable items on the spot. Testable items
include AC mains failure, damage to SPDs (SPDs with
alarm indicator or alarm contact), module failure and
DC fuse blowout (test shall be conducted on unload
fuse)
