SMA FLX Series Sensor Interface Option - Manual (Page 8)

2 Setup
2.1 Prepare for Setup
2.1.1 Verification via Display
Verify that the option is detected.
1. Turn on PV and AC connection.
2. In the display, go to [Setup → Calibration].
3. If the sub-menu “Irradiation sensor”,” Temp
sensor offset” or “S0 sensor input” is listed, then
this confirms the option is installed correctly.
4. If none of these sub-menus are listed, then the
option is not installed correctly. Actions:
- Disconnect PV and AC, and open the
cover to the inverter installation area as
described in 1.1 Installation.
- Check the option is pushed completely
into place and sits firmly with no
movement.
- Repeat steps 1 to 3.
- If the sub-menus are still not visible,
contact hotline.
2.1.2 Verification via Web Interface
Verify that the option is detected.
1. Turn on PV and AC connection.
2. In the web interface, go to [Setup → Calibration].
3. When the screen in Illustration 2.1 appears, then
this confirms the option is installed correctly.

Settings
4. When the screen in Illustration 2.1 appears with
the message ‘Required option is not installed’,
then the option is not installed correctly.
Actions:
- Disconnect PV and AC, and open the
cover to the inverter installation area as
described in 1.1 Installation.
- Check the option is pushed completely
into place and sits firmly with no
movement.
- Repeat steps 1 to 3.
- If the message ‘Required option is not
installed’ still appears, contact hotline.
2.2 Setup via Display or Web Interface
To set up the sensors ready for operation,
1. In the display, go to [Setup
→ Calibration →
Irradiation sensor], [Setup
→ Calibration → Temp
sensor offset], and [Setup
→ Calibration → IS0
sensor input]
2. In the web interface, go to [Setup
→ Calibration →
Sensors]
3. Enter the calibration and offset values as
described in Table 2.1.
Item Unit Description
Irradiation sensor
scale
mV(1000
w/m 2 )
The calibration value of the
irradiation sensor.
The value is usually written on a
label at the back of the sensor.
Note that this value must be
entered before the inverter will
recognise that there is an
irradiation sensor connected.
Irradiation sensor
temp. coeff.
% Calibration value for internal
temperature correction of the
irradiation measurement. Only
used for irradiation sensors with
integrated temperature compen-
sation.
PV temp. offset °C The temperature sensor may be
calibrated using an offset ranging
from
−5.0 to 5.0 °C.
Ambient temp.
offset
°C The temperature sensor may be
calibrated using an offset ranging
from
−5.0 to 5.0 °C.
S0 scale pulses/kW
h
In order to use an energy meter
(S0 sensor), the scale of the
energy meter must be entered
here.
