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