Operating Instructions
8-channel light barrier multiplexer
IMX-A830
GB
1. Introduction
Light barriers are used as the components of a higher-level
overall system for the detection of objects. They can only
operate with one Transmitter IT... and one Receiver IR... as
Trough Beam, Retro-Reflective or Diffuse Proximity.
2. Features
• Multichannel amplifier with modulated infrared light
•
8-channel installation system for tight assembly without
cross talk
•
Automatic Level Control (ALC) according to assembly
distance and direction
•
Range up to 55 m (180ft)
•
One transistor output for each channel (NPN/PNP)
•
Test function to check installation and signal strength
•
Programmable light / dark function
•
Programmable basic transmit level
• Switch-on and switch-off delay (0 - 7 s)
•
Master-slave mode
•
Transmitter and receiver terminals are short circuit proof
3. Description
This 8-channel automatic multiplexer has set a new standard
for devices of this type. It is an amplifier with an integrated
analysis unit. Up to eight transmitters and receivers can
be connected to each unit without possibility of cross talk.
The device activates the sensor heads cycling one after the
other (multiplex operation). During the activation, the state
of each channel is evaluated.
ALC
(

ontrol) is the main feature of this
infrared automatic multiplexer. According to the channels
condition, the appropriate transmit power level is continuously
calculated to an optimal value to guarantee steady switching
reaction, independent from the distance between transmitter
and receiver, mounting position, temperature etc.
The amplifier works with modulated infrared light which
provides high immunity to ambient light. The automatic gain
setting enables the user to simplify the installation and work.
Each channel has a transistor output (npn/pnp) and a
status LED.
All channels can be switched independent from each other
to the different working conditions. The sensitivity of the
device can be switched to 2 basic transmit levels. Also,
the transmitter power can be increased to optimize object
recognition.
A control unit, which can be activated by simply pressing a
button, is used to determine malfunctions in the transmitter
or the receiver. If nothing is defective, the test function shows
the signal quality by flashing an LED from 1 to 10 times. The
flashes are proportional to the received signal.
An alarm display and output, which shows errors and the
limit of the transmit power and is connectable with a PLC,
enables users to safely work with the photoelectric amplifier.

Security notes
When material damaged or personal injury, because of improper use or disregarding of security notes, the manufacturer
do not undertake any
liability. In this causes, any warranty claim expired.
•
The use of these light barriers are not allowed in applications, when the security of persons depend on the device
function.
• In overall system and their development using light barrier, the specific
security and accident prevention regulations
have to keep. The operating company of the overall system, for example a plant, are responsible for compliance
with the valid national and international regulations concerning the special application.
• This devices are only allowed to operate as directed, otherwise danger for example shortcircuit, fire or electric shock
may occur.
•
Do not open, change or rebuild the device.
•
Note the operating instructions before switching on.
•
When settings will done, the behavior of the device can drastically be changed.
•
Make sure, that the connected system is out of operating during the settings and starts operating properly after
adjustment.
•
If there is no safety operation practicable, the device has to put out of action and protect against unintentional operate,
for example by noticable damage or not operate as directed.
•
Do not use the device in explosive-dangerous environment.
•
Do only hand over the device with the instruction manual to others.
•
Dispose the device
environmentally compatible, in compliance with the regional rules.
