OSSD 1 (X1-12) and OSSD 2 (X1-11)
When the detection zone is interrupted, the two semiconductor outputs switch OFF and,
by way of elements such as positively guided relays, cause the monitored machine(s) to
shut down.
It is not admissible to control different safety circuits with a single OSSD. Connected
loads must exhibit a low-pass behavior in accordance with the plausibility control
conducted by the scanner (f
g
1kHz, C
L
100nF). The OSSDs are equipped with
an
internal electronic current limit to protect them against damage from overload.
For some sample connections, see Chapter 8.

Data communication
The interface X2 allows the
SD3-A1
to support two types of connections to the PC.
Communication via the X2 connector in RS-232 mode does not require any further
bridging. To enable data transfer in RS-422 mode, connect pin 5 with pin 6. The scanner
automatically adjusts itself to the appropriate transfer type and baud rate.
The interface (X2) is used for
Guard operation is only permitted with the PC cable (X2) or dummy connected screwed
ON. This also applies for transport and storage.
Please note the pin assignments specified in Chapter 9.5. For additional information on
using the X2 interface, refer to the instruction manual (software operation) for the
program “
SD3SOFT
”.

Integrating the SD3-A1 into Machine Controls
The following examples illustrate possibilities for integrating the
SD3-A1
into machine
controls.
Once the operating voltage pin X1-3 (+U
B
) has been connected to pin X1-1 (GND) and a
detection zone has been activated (X1-4, X1-6, X1-7 or X1-8), the unit is ready for
operation.
Please see the point “Define Detection / Warning Zones” in the instruction manual
(software operation) for the program “
SD3SOFT
”.
