1. Introduction
1.1 Introduction
RADIUS Log Light is a newly research & design inverter monitoring product of Gefran. It can collect and
analyse photovoltaic station inverter running data via Bluetooth connection, and display monitoring data on
LCD screen, user can browse data on computer as well. RADIUS Log Light can monitor maximum 4 inverters
simultaneously.
RADIUS Log Light has standard data communication interface, including RS232 serial port, USB port, and
Bluetooth, it can smoothly compatible with your existing systems.
RADIUS Log Light has the following features:
1. Remote monitor and control
2. Communicate with APV inverters via Bluetooth
3. Monitoring data store in SD card which plug to RADIUS Log Light.

Fig 2.1 Simple chart of RADIUS Log Light
The following table is components explanation:
Number Name Explanation
1 RS232 For rmware update
2 SD CARD SD card socket
3 MINI USB Power supply or battery charge by MINI USB (cable includ-
ed as standard)
4 SWITCH Power on/off switch

Radius Log Light 7
2.2 Wireconnection
1) Insert the USB terminal of USB wire to power adapter socket, and insert the opposite terminal (MINI
USB) to MINI USB port socket.
2) Insert SD card to SD card socket.
3) Connect power adapter to public gird power outlet
4) Turn on power switch of RADIUS Log Light.
2.3 LEDindicator
There are 3 LED indicators on the right of LCD screen, you can get RADIUS Log Light running status by check-
ing up the 3 LED lights.
LEDlights Function
BT Power Indicate Bluetooth modules status
BT State Indicate Bluetooth connection status
Charge Indicate charge status
1) BTPowerIndicator
If LED indicator blink once per several seconds, it shows bluetooth modules are working in normal sta-
tus. You can check out master device and slave devices by examine the blink interval of LED. LED blink
once every 2 seconds shown it’s a slave device, the master device’s blink interval is 5 seconds.
RADIUS Log Light is working in master mode and inverter bluetooth module in slave mode.
2) BTStateIndicator
Dark LED light indicates connection was established with other bluetooth device, a blink LED indicates
connection haven’t established.
If connection haven’t established, you can check whether RADIUS Log Light had stored logical address
of pair bluetooth device, by examine the LED blink times. Quick blink (2 times per second) indicate logi-
cal address had been stored, slow blink (once per second) indicate haven’t stored the logical address.
For master device, blink once every 2 seconds when searching device, quick blink 4 times in a second
when nding a pair device, blink once when connecting, and become dark in connected status.
The two indicators (BT power, BT state) are all dark when bluetooth modules are in sleeping status, or
working at parameter setting mode.
3) ChargeIndicator
Turn on if exterior power supply came in, else in dark status.

3. Buttonoperationandmenuinterface
Button Function
UP Optional item move up, move cursor in a item for parameter make change
DOWN Optional item down; Increase parameter value
ESC Back to previous menu, end of setting; Interface switching
ENTER Enter menu, conrm parameter value setting
Table 3.1 Button operation
The LCD screen became bright for 15 seconds delay after you press any of the four button. After 60 seconds
stop to press any button, the screen come to a sleeping mode, no word display in screen, you can press any of
the four buttons to let screen become bright.
3.1 CheckSDcardandscanBluetoothdevice
After turn on the switch, RADIUS Log Light rst display Gefran logo in screen:
Gefran <Display “Gefran” in art words
APV Solar
Then going to check SD card status.

SD CARD: NC
Fig 3.1 Check SD status
Then scan Bluetooth device.
From left to right indicates:
search times, registration times,
cancel times, number of valid
address
Bluetooth logo
xx xx xx xx < Bluetooth Scan Status
> Active Num: 0 < Number of inverter connected
Fig 3.2 Bluetooth scan
1) RADIUS Log Light rst display ”Gefran” logo when powered on.
2) About 10 seconds later it come to Check SD card status, in check SD card status RADIUS Log Light
start to check whether SD card existence, the process last for 30 to 120 seconds dur to actual situation.
3) Then RADIUS Log Light search for Bluetooth devices. RADIUS Log Light off line time, online time, dis-
covered device, active device will be displayed on screen.
4) a. If no device been searched, RADIUS Log Light will continue searching. Press “ENTER” button to
come to “Main Status” interface.
b. If some device been searched, RADIUS Log Light will display “Check Finish” in the end. You can
press “ENTER” to come to “MainStatus” interface.

3.2 MainStatusinterface
Main status interface display inverters’ running status, serial number of inverter, PV voltage, PV current, AC
voltage, AC current, output power, etc.
(*1) Automatically display when error occurs
Fig 3.3 Main status interface
All inverters power are display in Main Status interface. Press “UP” and “DOWN” button to select appointed
inverter, then press “ENTER” to check inverter’s detailed running parameters, for example, solar panel input
voltage and current, AC output voltage, AC output power, today’s energy, total energy produced.
Press “ESC” in Main Status interface can ENTER Main Message interface. “Active Num: x” stand for monitoring
number, “ALL PWR: xx W” stand for inverters’ total power, “ALL ENG: xx KWH” stand for total energy produced
by inverters.
