Chapter 3 Testing, Operation and Maintenance of the Power System
GIE 4820/3A/3.45KW Power Supply System User Manual
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.
