When the communication protocol is “Access Network Communication Protocol
between PSM-B9 Monitoring Module and the Host”, the communication address of
the monitoring module does not need setting.
3.3.2 Setting of System Parameters
Upon delivery, the default setting parameters of the monitoring module may be
inconsistent with the scene or custom of users’ demanding. So users should look
over and reset the configuration parameters of the power system through the host.
Then the normal operation and function testing of the power system can be
conducted after the correct parameters setting.
Detailed parameters can refer to Table 1-3.
Note:
When conduct system parameters setting through the host:
1. It must insure that the address parameters setting of the power system is
identical with the communication address set by the dial switch in 3.3.1 section,
otherwise the communication will be failed.
2. It must insure that the number of the rectifier module in the power system is
identical with the actual condition. Add to or remove the rectifier module from the
power system, it must re-modify the number setting of the rectifier module to make
sure according with the actual number. Otherwise the rectifier module alarm will
occur.
3.3.3 Testing of Battery Auto-Management
Power supply the load by the battery, cut off AC mains for above 15 minutes (
±
1
minute) then recover AC mains, all of the rectifier modules will be automatically in
current-limiting equalized charge state.
During the current-limiting equalized charge state of the module, it is normal that its
output voltage sometimes is below 53.5V.
Because the testing of battery auto-management requires strict for the system state,
it is not necessary to test battery auto-management, and the system has been
tested strictly in the factory before delivery.
