Deactivating the test pulses at the outputs of the SP-SDIO

888394763
With firmware version V2.00.0 and higher, it is possible to deactivate the test pulses at one or
more outputs of SP-SDIO84-P1 modules.
Deactivating the test pulses at any output reduces the safety parameters of all outputs!
Deactivating the test pulses at one or more safety outputs of an SP-SDIO module reduces the
safety parameters of all Q1 to Q4 safety outputs of this module.
• Be aware of this in order to ensure that your application corresponds to an appropriate
ATTENTION risk analysis and risk avoidance strategy.
• You can find more detailed information on the safety parameters here:
12, p. 70]
Be sure to use protected or separate cabling!
• If you deactivate the test pulses at one or more safety outputs, short-circuits at other
output circuits cannot be detected. This affects the safety function!
• In the event of a short-circuit after 24 V, it will no longer be possible to switch off the
output.
ATTENTION
Furthermore, it will not be possible to prevent reverse current from going into a switched-
off output, which will influence the capability of switching off the outputs.
Carry out cyclic tests when the test pulses at one or more safety outputs are deacti-
vated!
Once you deactivate the test pulses at one or more safety outputs, conduct the following
tests once a year:
• Switch off all of the safety outputs without test pulses simultaneously for at least one
ATTENTION
second via the logic program of the COMPACT module.
OR
• Restart the samosPRO system by switching off the supply voltage.
You will thus deactivate the test pulses at an output of the SP-SDIO:
 Connect an output element to the SP-SDIO module.
 Using the right mouse key, click on the output element and select the Edit command in
the context menu.
 Deactivate the Activation of test pulses of this output option. The test pulses of this out-
put will be switched off. A corresponding note will be displayed in the hardware configura-
tion area under the respective SP-SDIO module.
3.8.5

Single-channel use of outputs on the SP-SDIO

888395787
Be sure to consider a potential brief switch to high with single-channel safety outputs!
In the event of an internal hardware error, single-channel safety outputs (Q1 to Q4) can
switch to high once for 10 ms after the error has been detected. Consider this during your
risk analysis and reduction strategy. Otherwise, there is a hazard for the operator of the ma-
ATTENTION chine.
