4.- COMMUNICATIONS TEST AND REGULATION
4.1.- COMMUNICATIONS TEST
Check the communication between the inverter and the
CDP
, through the COM1
LED of the
CDP
:
A flashing (or steady) LED means communication has been correctly
established.
The flashing rate is one flash per second (if there is one inverter) and 1/n
if there are several inverters (where "n" is the number of inverters
connected).
If the COM1 LED is off, it means the
CDP
is not communicating with the
inverter. In this case check the communication cables and the inverter
communication configuration.
Correct communication between the
CDP
and the inverters connected to it can
be checked on the configuration web site. To do so, press the "
Show system
status
" button.
When this button is pressed, the
CDP
will scan the connected inverters and
indicate how many of the total number of inverters that the CDP has been
assigned to control have been detected.
The following image will appear if the communication is correct,
