Logic channel 1 and 2	Logic of channels 1 and 2	single logic asynchronous repetition OSSD (sensor A sensor is a type of transducer that converts one type of energy into another for various purposes including measurement or information transfer test must be switched off) any pulse repetition OSSD (sensor test must be switched off) short cut is no module fault
Logic channel 3 and 4	Logic of channels 3 and 4	single logic asynchronous repetition OSSD (sensor test must be switched off) any pulse repetition OSSD (sensor test must be switched off) short cut is no module fault
Store Code	This parameter is required for the safety Restore Mode	0x0000
Project CRC "Cyclic redundancy check" A CRC is a type of function that takes as input a data stream of any length and produces as output a value of a certain fixed size. The term CRC is often used to denote either the function or the function's output. A CRC can be used as a checksum to detect accidental alteration of data during transmission or storage	This parameter is required for the safety Restore Mode	0x0000

• Test pulses

  If the parameters Current Measurement active or Testing of outputs active are set to TRUE, the terminal generates test pulses at the outputs. To avoid generating test pulses at the channel outputs, testing of outputs active and Current measurement active must be set to FALSE.

  Please note that deactivating Current measurement active and/or Testing of outputs active may reduce the achievable performance level. A calculation example for the performance level can be found in the safety PLC "Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events application manual.

  There are no known applications for which it would make sense to set Testing of outputs active to FALSE, while Current measurement active is set to TRUE.

AKT2G-SDI-004 configuration for light barriers, light grids, light curtains etc.

The AKT2G-SDI-004 also supports direct connection of contact-free protective devices with two self-testing outputs such as light barriers, light grids, light curtains, laser scanners, etc.

• Sensors with self-testing outputs!

  Only sensors with self-testing outputs and a maximum sensor self-test duration of 350 µs may be connected to the AKT2G-SDI-004 (see illustration below).

Figure 8-43: Maximum permissible sensor self-test duration of 350 µs

Parameter

To connect these sensors please set the following parameters for the AKT2G-SDI-004 in the safety PLC software:

Connect the two sensor signals either to channels 1 and 2 or channels 3 and 4 and activate asynchronous repetition OSSD or any pulse repetition for the two inputs used under parameter Logic for channel x and y. The difference between these settings is that with any pulse repetition simultaneous tests of the OSSD signals up to 350 µs are allowed.

For the two inputs used set the sensor test for the AKT2G-SDI-004 to False.

Configuration of the AKT2G-SDI-004 for safety switching mats

The AKT2G-SDI-004 also supports direct connection of safety switching mats.

Parameter

To connect these switching mats please set the following parameters for the AKT2G-SDI-004 in the safety PLC software:

Connect the two sensor signals either to channels 1 and 2 or channels 3 and 4 and activate short cut channel x/y is no module fault for the two inputs used under parameter Logic for channel x and y.
