If the reading gate is open, the LECTOR
®
620 records images with a frequency of 60 Hz and
evaluates these by codes. Ideally, at least one code will have been completely recorded and
identified on an image. If the reading gate is closed, no images are recorded.
Signal sources for opening the reading gate:
• S
ENSOR / RESULT 1: A signal at digital input 1 (e.g. via a light barrier) opens the reading
gate.
• S
ENSOR / RESULT 2: A signal at digital input 2 (e.g. via a light barrier) opens the reading
gate.
• E
XTERNAL INPUT 1: A signal at external digital input 1 (e.g. via a light barrier) opens the rea-
ding gate.
• E
XTERNAL INPUT 2: A signal at external digital input 2 (e.g. via a light barrier) opens the rea-
ding gate.
• SOPAS C
OMMAND: A command to open the reading gate is expected e.g. from an external
controller (PLC). (A detailed list of the command language is available from SICK on re-
quest.)
• A
UTO CYCLE: The reading gate is opened and closed automatically after a defined cycle
(using the Pulse and Pause parameters) (e.g. if the feed speed stays the same and the code
position is constant or for manual code reading)
• CAN: The signal for opening and closing the reading gate is expected via the CAN inter-
face. In a network of devices that communicate with each other via the CAN network, the
signal for opening the reading gate can be distributed. For this, a suitable trigger signal is
received by a device (usually the master) and distributed to the other CAN network.
• U
SER DEFINED COMMAND: You can freely define a command for opening the reading gate,
which is e.g. generated by an external controller (PLC) and transmitted to the LECTOR
®
620.
• F
REE RUNNING: The reading gate is permanently open. As a result, manual code reading is
possible without an external trigger signal (e.g. from a light barrier). Signals for opening/clo-
sing the reading gate are ignored. As it is therefore not possible to define a specific point in
time for data output, a signal for N
O READ cannot be output. The time of output and the rea-
ding speed depend on the degree of utilization of the LECTOR
®
620.
5.4.2.1.4 Stop delay
You can use the Stop delay parameter to influence the time for closing the reading gate. The
unit can be selected in the Trigger delay parameter.
A positive value enables the reading gate to be closed later, e.g. to extend the evaluation
period for codes at the rear of an object.
•
B. STOP DELAY (additional time/distance for which the reading gate remains open after
event B)
