Synchronization beam
Synchronization beam
is used to define whether the first beam (at the cable outlet) or the last beam
is used for optical synchronization.
NOTE
•
The transmitter and receiver must be set to the same value.
•
The synchronization beam cannot be suppressed.
•
Interruption of the synchronization beam is signaled at both ranges.
Input option:
first / last
Factory setting:
first
3.5.8
Smoothing
Smoothing (range 1)
specifies the number of beams which must be interrupted before beam
interruption is signaled. The interrupted beams do not have to occur consecutively.
If ranges are used (see the section 3.5.6 "Start beam of second switching range" on page 14), the
value for the second range is defined using
Smoothing (range 2)
.
Example
•
Smoothing (range 1)
= "5":
Output switches when 5 or more beams have been interrupted.
•
Special function with:
Start beam of second switching range
= "1":
Both smoothing values relate to the entire monitoring range.
•
Smoothing (range 1)
= "2":
Smoothing (range 2)
= "3":
Start beam of second switching range
= "10":
If, for example, beam 4 and 7 are interrupted, range 1 switches; if beams 10, 11 and 20 are
interrupted, the second range switches.
3.5.9
Pulse stretching [ms]
The parameter value
Pulse stretching [ms]
delays the change in state of the switching outputs by
the set value in milliseconds (ms). A maximum delay of 255 ms is possible.
Input option:
0…255
Factory setting:
0
3.5.10
Top blanking
When the device is switched on, the beams covered at the beginning of the bar can be permanently
blanked.
Top blanking
specifies how many consecutive beams can be blanked.
This function is intended for elevator applications and only available where
Synchronization beam =
last
.
3.5.11
Relative switching threshold: Warn
If the intensity of the received signal remains below a set value (
Relative switching threshold: Warn
for a certain period (
Warn signal delay [s]
), the CSL 505 switching light curtain signals a "minor
error".
Possible remedies:
•
Clean the beam exit.
•
Align the transmitter and receiver and perform the teach event again.
If
Relative switching threshold: Warn
is set to "0", the "soiling alarm" is deactivated.
Input option:
0…255
Factory setting:
