①
Loss of the safety function
due to the use of unsuitable
voltage supplies
WARNING
For the voltage supply at the bus coupler, use only voltage
supplies acc. to EN 50178/VDE 0160 (PELV).
Ensure that the output voltage of the voltage supply for the
bus coupler does also not exceed 30.2 V in case of error.
Observe the general safety instructions, refer to
"General safety instructions" on page 7
②
Loss of the safety function
due to load switching at maxi‐
mum leakage current
WARNING
●
At this current, note that the load may not be switched
and remain in the enabled state.
●
Observe that when selecting the actuator.
③
Loss of the safety function
due to load switching at mini‐
mum holding voltage
WARNING
●
At this voltage, note that the load may not be switched
and remain in the enabled state.
●
Observe that when selecting the actuator.
④
Loss of the safety function
due to the switch-on pulse
WARNING
●
Note that the load may neither fail nor react safety-criti‐
cally if the switch-on pulse (light test) is 1 ms.
●
Observe that when selecting the actuator.
⑤
This switch-off pulse can
cause the loss of the safety
function.
WARNING
●
Note that the load may not react safety-critically if the
switch-off pulse (dark test) is 3 ms.
●
Observe that when selecting the actuator.
Loss of the safety function
due to parasitic voltage
WARNING
●
Connect the ground of the actuator to the respective
ground terminal point of the corresponding output on the
IndraControl S20 plug. Using an external ground is not
permitted.
●
The connected load may not dangerously react on test
pulses.
