Installation and operating instructions
Switching light curtain CSL 505
Function
The CSL 505 switching light curtain monitors a defined control area with multiple
invisible infrared light beams. The light curtain systems consist of a transmitter
bar (Tx) and a receiver bar (Rx) made of anodized aluminum. They operate on
the principle of multiple throughbeam photoelectric sensors, whose output
signals are linked. If any light beam between transmitter and receiver is
interrupted, this is registered by the integrated evaluation electronics and
signaled at the antivalent push-pull signal outputs (PNP & NPN).
Intended use
The CSL 505 switching light curtain can be mounted on building
components, machine elements as well as other support elements. The
device must be secured with the existing fastening options (holes, bolts, ...).

Installation recommendations

Teach event
The teach event is important for ensuring the function of the light curtain.
Therefore, perform the teach event on the receiver after every change to
the bars. For an error-free teach event, the monitoring range must be clear
and both LEDs of the receiver bar must illuminate continuously. If the teach
event was not successful, please check the alignment of the transmitter and
receiver
When switching on, connect pin 2 or
pin 4 of the receiver bar to +24 V DC.
Both LEDs on the receiver bar
illuminate. The first valid value is
stored.
Completely disconnect the voltage of
the light curtain. Also disconnect the
voltage on pin 2 / pin 4 prior to the
next restart.
Check the switching function.

except for -ER model

approx. 1000 ... 10000 mm for -ER model
Read these instructions before commissioning.
Mount the bars without any mechanical loading.
In general, rough alignment of the bars is sufficient.
The transmitter bar and receiver bar must be able to "see"
over the entire monitoring range.
For optical synchronization of transmitter and receiver, either
the bottom or top beam (configurable) is used. This beam
must not be continuously interrupted or suppressed.
Only connect and disconnect bars while in a de-energized
state.
A potential difference of 60 V between the bar housing and
the supply voltage must not be exceeded.
Avoid ground loops: all bars must have the same grounding
potential.
Interference from ambient light (e.g., from flash lamps or
sunlight) on the receiver bar is to be avoided.
Avoid object reflections.
Mutual interference of optical sensors is to be avoided.
