3Product description
3.1 General information
The CSL 505 switching light curtains monitor a defined area using invisible, infrared light beams. The
light curtain systems consist of a transmitter bar (Tx) and receiver bar (Rx). They function in the
same way as a system comprising multiple throughbeam photoelectric sensors. If one of the light
beams between the transmitter bar and receiver bar is interrupted, this is registered by the evaluation
electronics and signaled at the push-pull signal outputs.
3.2 Performance characteristics
•No separate evaluation unit required. The device is operated directly from a 24 V DC supply.
•Two short-circuit proof push-pull signal outputs: Can therefore be used both as PNP and as
NPN.
•Plug-and-play: The CSL 505 switching light curtains are fully preconfigured at the factory.
•A teach event automatically adapts the operating range.
•Increased resolution possible thanks to crossed-beam scanning.

3.5.4 Relative switching threshold
During the teach event, the value for the brightness of every individual beam is measured and saved
in a non-volatile memory. The absolute switching threshold per beam is determined by multiplying by
the relative switching threshold (percentage of Relative switching threshold ).
To ensure that the system responds even at low beam coverage levels, the switching threshold must
be increased. The default value is 85 (corresponds to approx. 33 %). The switching threshold should
be set to max. 179 (corresponds to approx. 70 %).

Relative switching threshold = 0

Input option: 0…255
Factory setting: 85
3.5.5 Blanking of beams
Various options are available for blanking beams.
It is important to note that the synchronization beam must always remain active!
3.5.5.1 Manual blanking via CSL505 software
You configure manual blanking in the beam configuration area on the right side of the CSL505
software program window. Select there the receiver element that is to be deactivated.
3.5.5.2 Blanking of defective beams
The parameter Blanking of defective beams specifies the number of beams that are tolerated. If this
number exceeds the value for Blanking of defective beams , a serious error is signaled. Below this
number, defective beams are blanked and not taken into consideration during evaluation.
All other blanked beams are not added to Blanking of defective beams .
Input option: 0…160
Factory setting: 0

Product description
Leuze electronic GmbH & Co. KG CSL 505 14
3.5.5.3 Autom. beam bl. delay [s]
Time that must pass before a beam interruption is blanked. Specified in seconds.
Input option: 0…255
Factory setting: 0
3.5.5.4 Maximum automatic beam blanking
Permanently interrupted beams can be blanked automatically.
Automatic beam blanking is used to set how many adjacent beams of the same type (e.g. parallel
beams) are allowed to be blanked. The count restarts after an active beam.
Example
Automatic beam blanking = 1
Beam 3, 5 and 8 can be blanked. If beam 9 is additionally covered, this beam is not blanked and the
CSL 505 switching light curtain remains interrupted.
This function is often used for elevator applications and enables permanently interrupted beams to
be blanked automatically.

NOTE
•Switching ranges with non-parallel beams overlap.
•If the synchronization beam is interrupted, both ranges switch.
•The dark switching or hell switching (factory setting) parameter applies to both
ranges.
•If "1" is selected, the two ranges together cover the entire monitoring range.
•Smoothing can be defined for each range

Product description
Leuze electronic GmbH & Co. KG CSL 505 15
3.5.7 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: 147

Product description
Leuze electronic GmbH & Co. KG CSL 505 16
3.5.12 Warn signal delay [s]
Time after which soiling is signaled. See the section 3.5.11 "Relative switching threshold: Warn" on
page 15.
Input option: 0…255
Factory setting: 60
3.5.13 Power-up teach delay [s]
Switching threshold setting is activated at power-up. After a time (in seconds) has elapsed, the
determined reference values are saved in a non-volatile memory, provided that the monitoring range
was free. Otherwise the original reference values are used. This teach event at power-up is
deactivated with "0" and "255".
Input option: 0…255
Factory setting: 0
3.5.14 Blanking warning
Blanking warning specifies the position (beam number) as of which an error message is issued in
the event of blanking.
Input option: 0…160
Factory setting: 0

3.6 Parameters (transmitter)
When the transmitter is switched off by means of an input signal, a switching operation is specifically
triggered, e.g. for a start test. Various functions are configurable.
When the transmitter is deactivated, the receiver reacts in the same way as for a beam interruption,
and the transmitter LED flashes.
The transmitter cycle is not stopped; the system is therefore quickly ready for operation again after
transmitter activation.
3.6.1 High signal or Low signal at input
Use the parameter value High signal at input for transmitter deactivation with active transmitter
input, or Low signal at input for transmitter deactivation with inactive transmitter input.
