Deactivating the test pulses at the outputs
888366731
It is possible to deactivate the test pulses at one or more output pairs. The outputs are combi-
ned into four output pairs with the SP-COP2: Q1/Q2, Q3/Q4, IQ1/IQ2, and IQ3/IQ4. The test
pulses each act upon the two outputs of an output pair.
Switching off the test pulses at one of the two outputs of an output pair will switch off
the test pulses of the entire output pair!
Deactivating the test pulses at one or more safety outputs of a SP-COP module reduces the
safety parameters of both safety outputs of the respective output pair of this module.
ATTENTION
• Be aware of this in order to ensure that your application corresponds to an appropriate
risk analysis and risk avoidance strategy.
• You can find more detailed information on the safety parameters here:
reference values [ch. 12.2, p. 84]
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
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

second via the logic program of the controller module.
OR
• Restart the samosPRO system by switching off the supply voltage.
You will thus deactivate the test pulses at an output of a

The test pulses of this output will be switched off. A corresponding note will be displayed
in the hardware configuration area under the respective SP-COP module.
3.5.6
Single-channel use of outputs
888368267
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 can switch to high
once for 10 ms after the error has been detected.
• Consider this during your risk analysis and reduction strategy.
ATTENTION
Otherwise, there is a hazard for the operator of the machine.
