GRT1-PD2 and GRT1-PD2G I/O Power Feed Units Section 8-3
There are three methods that can be used to reset the overcurrent status of
GRT1-PD2G.
• Short the RESET terminal to the V (R) terminal. The overcurrent protec-
tion function will be automatically reset.
• Connect the RESET terminal to an output terminal of a Transistor Output
Unit (e.g., the GRT1-OD4-1 (PNP)) and turn ON the output signal for at
least 100 ms. If the Output Unit and I/O Power Feed Unit are connected to
different I/O power sources, ground them to the same point.
• Turn the power supply OFF and ON. The overcurrent protection function
will be automatically reset.
