The jumper block (J3) has three possible positions, 1->2, 2->3, 3->4
1->2 = is for programming.
2->3 = used for automatic sense of leak current
3->4 = used when leak current sense is defined by CV's.
So run position is either 2->3 or 3->4 depending on what you select; auto or CV defined.
If you were allready aware of this info, sorry to waste your time.
Seeking advise about programming DCC Specialites Block watcher. I have installed 40 of these units on the layout. Some are showing occupancy even though there is no current draw through the block. Directions indicate that you can set current level trip via cv programming or have block watcher auto set level on start up. The printed directions and the web site both show that 1-2 is the programming position - after setting CV's you are instructed to return the jumper to run position (Position not defined) in another place you are instructed to "return to 2-3 position which is the setting for auto determiing current flow, I am confused?
Has anyone programmed the CV's for current flow.
