Parameters
5.4.2.1.8
Or
You can use the
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
/ R
ESULT
1: A signal at digital input 1 (e.g. via a light barrier) closes the reading
gate.

2: A signal at digital input 2 (e.g. via a light barrier) closes the reading
gate.
• E

NPUT
1: A signal at external digital input 1 (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

RACKING
: The reading gate remains open for a defined time/distance (
).
• G
OOD
R
EAD
: The reading gate is closed as soon as the G

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

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
