% Length Reset Input Action

%<CR> Read

Response Format: <N>

%<N><CR> Set

<N> is an integer specifying the Length Reset Input Action mode. It can be any of the values in the table below, but the default is 0.

This setting controls when the length reset input resets the length. Depending on the type of output you have connected to the LS8000-3, you may wish to reset on either rising or falling edge, or on a level. The dark lines in the figure below indicate where the length is reset.

Using an edge-triggered mode allows an instantaneous reset, and using a level triggered mode allows you to reset the length and hold it at zero for a period of time.

Value		Mode	Example
	Level Triggered (Active High)
0	Input High = Reset, Input Low = Not
	Reset
	Level Triggered (Active Low)
1	Input Low = Reset, Input High = Not
	Reset
2	Rising Edge Triggered
	Reset on Low	High Transition
3	Falling Edge Triggered
	Reset on High	Low Transition
4	Toggle Edge Triggered
	Reset on High	Low or on Low	High
5	Length Reset Input Disabled		Input is ignored

$R Length Reset Value

$R<CR> Read

Response Format: <N>

$R<N><CR> Set

<N> is a positive or negative integer specifying the Length Reset Value scaled by 1,000.

This setting can be used to introduce a constant offset into the length measurement. This is useful when measuring discrete parts using multiple external Material Present detectors. The Length Reset Value can be set to the distance between the sensors in order to automatically add the length onto each measurement. See the Connecting Material Present Switches section for details.
