• Apply the rated DC voltage to terminal A4, B4, ..., A6 of terminal block TB4, and A14, B14
and A15 of terminal block TB3.
Check that the status display corresponding to the input signal changes from 0 to 1. (For details
of the binary input status display, see Section 4.2.4.2.)
The user will be able to perform this test for one terminal to another or for all the terminals at once.
