1. General description
The sun sensor is used to measure the irradiance in photovoltaic systems. Among other
things, the instantaneous irradiance in W/m² and the module temperature in °C are available
as output signal. With the integrated high-resolution ADL-FE Field Extension, the analog
signal of the solar module is converted into a digital RS485 signal.

Instruction manual
Connection cable M8 (for Power supply and RS485 communication)
Cover caps for unused connectors
Optional components:
o external temperature sensor
o wind speed sensor
o Y-splitter (when both optional sensors are ordered)
4. Mounting ADL-SR®
The ADL-SR® is designed for outdoor installation. The front of the reference cell should be
aligned depending on the requirement level or the same angle as the solar modules. At the
rear there is a small hole with a ventilation membrane. The ADL-SR® must be mounted so
that this hole points downward and no rain water can penetrate. In this bore no objects may
be inserted, otherwise the membrane is damaged.
