
Allocating the SEN Signal to a General-Purpose Input
Type Signal Connector Pin No. Signal Status
Input SEN CN1-40 to CN1-46
A circuit example for when the SEN signal is allocated to CN1-40 to CN1-46 on the I/O signal
connector is provided below.
Refer to the following section for the procedure to allocate input signals.
