Installation
5.4 Sensor basic
The Mencke & Tegtmeyer GmbH engineering practice solar radiation sensor
must be fitted in such a way that the sensor solar cell and the solar unit modules
are aligned as similarly as possible to the sun, i.e. the sensor must have the
same alignment and inclination. The position of the sensor should be selected
so that there is as little overshadowing as possible and also so that snow in win-
ter cannot impair the operation of the sensor disproportionately. It is advisable to
fit it on the side or above the solar unit to achieve this. With units that are paral-
lel to the roof protruding fitting bars can normally be used as a fitting surface.
In other cases a suitable fitting aid may have to be acquired.

Important:
It is not necessary to open the sensor to fit it. However, if the housing is opened no
there can be no guarantee of watertightness and proper operation.
Wiring the data line to the Solar-Log
The connection cable has 4 wires and includes the 12 V power supply
and the data line to the Solar-Log.
No separate power supply is required.
The connection cable can be extended (up to 50 m). However, an 8 V
supply voltage at least must be provided at the end of the cable.
The cable must also be suitably protected in outside areas. The cabling
in inside areas can consist of a shielded data cable.
The sensor basic is connected to the Solar-Log via the RS485 interface
parallel to the inverter bus (from firmware 2.5) or via a free RS485 interface.
The cable shielding must have an equipotential bond.
The four wires in the connection cable must be connected to the 4 pin
connection plug on the Solar-Log™. The connection assignments are
printed on the back of the sensor and must be made as follows:
Solar-Log™ terminal strip connector
Sensor basic cable
1 (Data+)
Brown: Data+
2 (+12 V)
Red: +12 Vdc (Vcc)
3 (GND)
Black: 0 V (GND)
4 (Data-)
Orange: Data-
Starting up
When the Solar-Log is switched on, the sensor box is also powered up
automatically.
Then the sensor basic must be configured to the required
RS485 interface:
1 On the display call up Config / Start /Initial configuration or the web inter-
face on the Solar-Log200.
2 When selecting the inverter tick M&T Sensor.
3 Carry out inverter detection. The sensor basic is integrated into the system
like an inverter.
