3B) If MOH relay control is required in DK16, the Base Unit or the PIOU/PIOUS relay may be selected in Program 77-1. Follow Program instruction to make the selection.

4A) Set PIOU jumper plug P11 to MAKE or BREAK position as required:

•MAKE (M)—Shorts the normally open contacts (pins 9 and 34) when MOH is activated.

•BREAK (B)—Opens the normally closed contacts (pins 9 and 34) when MOH is activated.
