Start-up
The start-up is done in the following order:
•If necessary change the configuration of the Ethernet Converter, described at
page 4 of this manual and the RiCo large display, described at the manual of the
display
•Disconnect all devices from their power supply and do the installing
corresponding to the connection scheme at page 6
•Reconnect all devices to their power supply
Normally the Solar-Log and the Ethernet Converter are connected via a local area
network (LAN). Both devices are connected to a switch, router, etc.
It is possible to connect both devices directly also, using a crossover link. A crossover
adapter is in scope of delivery.
The Ethernet Converter provides a red LED, which indicates the data flow. In the
connection scheme the LED is marked with L. Every 30 seconds requests are send to
the Solar-Log. This is indicated by a LED flash. If the Ethernet Converter gets a valid
answer from the Solar-Log the LED flashes a second time. This is repeated eight times.
So if you see these double flashes eight times every 30 seconds, the communication
between Ethernet Converter and Solar-Log is successful.
If the LED flashes once every 2 seconds only, the communication via network is not
possible. Please check the network settings at the converter, the Solar-Log and the
LAN connection.
Testing the RS-485 connection between Ethernet Converter and large display
Directly after establishing the power supply to the Ethernet Converter the LED lights
up for two seconds. In this time the Ethernet Converter sends zero valued protocols
via RS-485 to the large display. With this option the communication between Ethernet
Converter and large display can be tested independent from the communication with
the inverters.
Do the following steps:
•Power up the ready configured and wired large display and wait until the display
shows dashes in all lines
•Only now power up the Ethernet Converter
•After the flashing of the LED, the large display must show 0in all lines
