No. The relay number. Up to 4 relays can be used.
Active Check a box to make the associated relay active. Remove the checkmark to disable
the relay.
NO / NC Used to set the relay’s normal operating state to open or closed, i.e.,
“Normally Open” or “Normally Closed.
Timer Sets the time that the relay switch will stay in its triggered state, before returning to
its normal open or closed position. For example, for Relay No. 1 above, after 5 parts
failed the switch would open for 0.5 seconds, then close again.
Checks the “Count” number, which is entered in the adjacent column to the
right. The switch state changes when the number of failed parts equals the
count number. When the timer value is reached the switch will return to its
normal closed state.
Response Channel State. Triggers on a non-normal condition. This mode
compares the actual part status (good or bad) against the condition indicated
in the Digital Output panel. When the part condition matches the indicated
setting, the relay switch leaves its normal state. For example, with Relay
Number 2 [above] when Ch 1 and Ch 2 both fail, the normally closed switch
will open. When the timer value is reached the switch will return to its
normally closed state.
Type
Manual trigger. The relay switch will remain in its normal state until
manually changed.
Count Sets the number of consecutive failures. Used in conjunction with the “count” type.
Ch 1
Ch 2
Ch 3
Ch 4 Ch 1 through Ch4 cells are used to set a channel’s trigger condition in relation to the
“good” or “bad” state of a part. In the example above, Relay No. 2 will stay closed
as long as channel 1 and channel 2 have passed parts. If either or both have a failed
part the condition triggers the Relay switch to open. When the timer value is
reached the switch will return to its normal state.
