The SmartLogger2000-10-C/11-C provides two PT ports. The PT1 port can connect to a three-wire or two-wire temperature sensor, whereas the PT2 port can connect to only a two-wire PT100/PT1000 temperature sensor (PT100/PT1000 for short).
- If the AI port has been connected to a temperature sensor, the PT port can be reserved.
- If the PT1 port connects to a two-wire PT100/PT1000, you need to short-circuit the GND port to one – port using the delivered short-circuit cable.
- For details about the cables and cable connection operations, see the documents delivered with the PT100/PT1000. The PT port on the SmartLogger is marked + and –. Connect the cables correctly according to the silk screens.
- PT1 supports the connection to a three-wire and two-wire PT100/PT1000 temperature sensor.
- PT2 supports the connection to only a two-wire PT100/PT1000 temperature sensor.

Add the EMI in Smartlogger2000:
Check first the communication address that the inverters has and set to the EMI different than inverters connected:
Maintenance à Connect device à Add device à select device type EMI and connection mode AI; address should be different than the existing address of the inverters à Add device.
Set the running parameter for the EMI
Set the port numbers corresponding to Ambient temperature, PV module temperature, Custom 1,and Custom 2 in the Signal Name column to PT1 or PT2.
Check the running info.
