The monitoring status can be seen by users through LCD screen.
The installation is completed once the monitoring interface shows up on LCD screen.
According to what shows on the LCD screen, the maintenance personnel can see
where the problem comes from when they are fixing the equipment.
1.If the LCD screen stays at the interface of
unlocking
and
constructing
network
,it
means the network construction fails. Then MI should be checked to make sure it is
connected properly and the MI power is on.
2.If it shows on LCD screen for a long time that the the number of MI units is less than
that of MI units connected to EnverBridge, it’s time to check whether there is a failure
on a certain MI equipment.(As to which one is not working, please get information
form long-distance or local server.)
3.According to the displaying interface of failure, maintenance personnel can locate
the failure and start the maintenance work.
Safety checks should be performed at least every 12 months by manufacturer’s
qualified person who has adequate training, knowledge, and practical experience to
perform these checks. The data should be recorded in an equipment log. If the device
is not functioning properly or fails any of tests, the device has to be repaired.
To ensure safe disconnection of the EnverBridge from the solar power plant, it must
NOT be carried out under load conditions. Ensure the following disconnection steps
are carried out in the order shown:
1. Disconnect the AC by isolating the branch via the circuit breaker.
Or Disconnect the plug from the wall socket.
2. Disconnect the Ethernet cable.
3. Remove the EnverBridge from the system.
Only trained and authorized professional personnel WHO ARE FAMILIAR WITH THE
REQUIREMENTS OF SAFETY is allowed to perform servicing and maintenance work.
6.5 Application
6.5 Fault display
20 minutes after data collection, a making-up network construction will take place in
case there is any missing connection of MI. “MI connecting” which shows on the first
line of LCD 1602 screen indicates the connection to MI is taking place and “x MI
connected” on the second line indicates how many MI units have been connected
with x referring to the numbers of MI units connected.
If there is a system malfunction, FAILURE shows on the displaying interface. The ID
number(s) of failed MI can be seen on the first line of the interface with the informa
-
tion of failure following it. Please refer to 2.5 to get a detailed explanation of failure.
What shows on the second line of LCD interface is the same as the monitoring
interface of LCD.
