alarm (red)LED will be illuminated solidly. Release the cold start switch once the alarm LED is on solid.
5 Configuring the MP2x
The MP2x is designed to work without any programming requirements. Though there are a few settings
that can be changed via Modbus RTU if needed. For example, the default address of the MP2x is 247. If
you want to change the address of the MP2x because you have multiple units then you would connect
the MP2x to a Modbus polling software such as
“Modbus Poll” or use the MP2 to change the address.
The following registers can be changed to meet your application:
