5.8.5.2.2
Teach-in stop by
Depending on the setting for the
parameter, the
parameter
is used to define which signal or condition stops teach-in of the matchcode.
• T
EACH
-
IN
TRIGGER
SOURCE
: Teach-in is stopped by a signal (e.g. a key switch) at one of the
digital inputs of the LECTOR
®
620.
• O
BJECT
TRIGGER
: Teach-in stops as soon as the reading gate is closed.
• T
AUGHT
V
ALID
C
ODE
: Teach-in stops as soon as a matchcode was read successfully.
5.8.5.2.3
Teach-in condition
parameter defines the condition in which the newly taught-in match
code content is stored. The selected condition is used as a basis when activating the target/
actual comparison. Each code that is read is compared to the read-in code content for the
target condition.
The code contents to be compared are assigned to a condition via the
parameter. The taught-in match codes can be started and activated at a later time, subject
to the condition.
5.8.5.2.4
Invert condition
A condition can be inverted using the
parameter. Inverting a condition al-
lows all code contents to be approved except the taught-in match code content.
With this function, it is possible to prevent a particular product from leaving the production
line.
5.8.5.2.5
Teach-in code content
parameter is activated, the code content of the matchcode is
taught in and included as a condition.
This reduces the likelihood of the code being confused with other codes.
5.8.5.2.6
Teach-in code ID (type)
parameter is activated, the code type of the matchcode is
taught in.
This reduces the likelihood of the code being confused with other codes.
5.8.5.2.7
Teach-in code length
parameter is activated, the code length of the matchcode is
taught in.
This reduces the likelihood of the code being confused with other codes.
