• Apply the rated DC voltage to terminal 1-2, 3-4, 5-6, 7-8, 9-12, 10-12, 11-12, 13-16,14-16,
15-16 of terminal block TB3, TB5 and TB7.
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.
