Quality Page Description (continued)

Input Polarity

Radio buttons are available to choose the meaning of the quality input. Options

are “On Means Good” and “On Means Bad”.

To change the meaning of the quality input:

Press either ”On Means Good” or On Means Bad”. A dot will appear in

the radio button of the selected quality input type.

An active input can be set to mean Good or Bad. This section includes an indica-

tor to show the state of the input with the meaning of this state shown underneath.

Messages will read “Good at Input” or Bad at Input” The green window will

change to red when “Bad at Input” is displayed. When Quality Control is enabled

the offsets used with the cutter will affect the second message “Good at Cutter” or

“Bad at Cutter”. These messages are also color-coded. A green background will

be displayed when “Good at Cutter” is shown and a red background will be dis-

played when “Bad at Cutter” is shown.

Debounce

This filter is used with the Good/Bad input. A setting of “0” should be used when

using an input source that is transistorized. If the input is a volt-free relay contact

then Debounce filter can be used. Relay contacts “bounce” their signal when they

turn on and off. When not filtered correctly they can confuse the sensors that cap-

ture their position. A typical setting for a relay contact filter is 0.050 seconds.

NOTE: The Debounce value can be

changed by pressing its individual

windows and using the keyboard

method to alter the value.
