1. A split EMI is composed of various sensors. Each sensor needs to separately connect to the
SmartLogger.
2. The SmartLogger can connect to a current-type or voltage-type sensor through an AI port.
3. One sensor connects to one AI port. This document describes only the connection between the
solar radiation sensor and the SmartLogger. Connections between other sensors and the
SmartLogger are the same.
4. For details about the cables and cable connection operations, see the documents delivered with

SmartLogger.
2. The SmartLogger can connect to a PT100/PT1000 temperature sensor through a PT port.
3. If the AI port has connected to a temperature sensor, the PT port can be reserved.
4. The PT1 port can connect to a three-wire or two-wire PT100/PT1000 temperature sensor,
whereas the PT2 port can connect to only a two-wire PT100/PT1000 temperature sensor.
5. If the PT1 port connects to a two-wire PT100/PT1000 temperature sensor, you need to short-
circuit the GND port to one – port using the delivered short-circuit cable.
6. For details about the cables and cable connection operations, see the documents delivered with
the PT100/PT1000 temperature sensor. The PT port on the SmartLogger is marked + and –.
