Description

The 8-channel automatic mulitplexer from Pantron
is a processor controlled amplifier with an integrated
analysis unit. Up to eight transmitters and receivers
can be connected to each unit without possibility of
cross talk. 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.
For each channel, the multiplexer has one transistor
output (pnp/npn) and a yellow status LED.
All channels can be switched independent from each
other to different working conditions by DIP-switches.
The sensitivity of the device can be switched to 4
basic transmit levels using the same method. 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.
A line display shows the received signal intensity. The

more flashes received, the stronger the signal.
If more than 8 channels are required, serveral
8-channel automatic multiplexers or 8-channel
standard multiplexers can be synchronized via
master-slave operation.
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
photo-electric multiplexer.

This operation mode is used for the physical alignment of the sensor heads and to test the installation (wiring and setting). The sensore heads will be activated cycling one after th other. The state of the beam is not displayed.
