Parameters
5.4.2.1.8 Or
You can use the Or parameter to choose a third signal source/condition for closing the rea-
ding gate.
For the reading gate to be closed, one of the signal sources/conditions must be met.
• N
OT DEFINED: No function for closing the reading gate defined
• T
RIGGER SOURCE: The reading gate is closed by the same signal source that opened it. (For
example, opening of reading gate as soon as an object breaks a light barrier and closing of
reading gate as soon as the object is no longer in front of the light barrier.)
• S
ENSOR / RESULT 1: A signal at digital input 1 (e.g. via a light barrier) closes the reading
gate.
• S
ENSOR / RESULT 2: A signal at digital input 2 (e.g. via a light barrier) closes the reading
gate.
• E
XTERNAL INPUT 1: A signal at external digital input 1 (e.g. via a light barrier) closes the rea-
ding gate.
• E
XTERNAL INPUT 2: A signal at external digital input 2 (e.g. via a light barrier) closes the rea-
ding gate.
• SOPAS C
OMMAND: A standard command to close the reading gate is expected e.g. from an
external controller (PLC). (A detailed list of the command language is available from SICK
on request.)
• T
IMER/TRACKING: The reading gate remains open for a defined time/distance (Reading
gate length).
• G
OOD READ: The reading gate is closed as soon as the GOOD READ condition has been met
(e.g. the required number of codes was read). As a result, the reading gate is only open for
as long as necessary (direct notification).
• U
SER DEFINED COMMAND: You can freely define a command for closing the reading gate,
which is e.g. generated by an external controller (PLC) and transmitted to the LECTOR
®
620.
• C
ONDITION MATCH 1: The reading gate is closed as soon as the condition is met.
• C
ONDITION MULTCODES1: The reading gate is closed as soon as the number of identified co-
des matches the required number.
• C
ONDITION TEACHIN1: The reading gate is closed as soon as the Matchcode Teach-in 1 con-
dition is met.
• C
ONDITION TEACHIN2: The reading gate is closed as soon as the Match-code Teach-in 2 (Ad-
ditional) condition is met.
5.4.2.1.9 Pulse
If the A
UTO CYCLE signal source is selected under the Start by parameter, the Pulse parame-
ter is used to enter the duration for which the reading gate stays open. The unit can be selec-
ted in the Trigger delay parameter.
5.4.2.1.10 Pause
If the A
UTO CYCLE signal source is selected under the Start by parameter, the Pause parame-
ter is used to enter the duration for which the reading gate is closed. The unit can be selec-
ted in the Trigger delay parameter.
