Connecting outputs
The easySafety device has safety outputs (QR/QS) and test
outputs with test signals (T1-T4) exclusively. Test signals are
used to detect cross circuits (
Connecting the safety outputs (QS/QR)
A value that is read at the safety input and processed in the
safety circuit diagram can be output safely via the output QR
(redundant relay output) or one of the outputs QS (safety
transistor/relay outputs).
The safety outputs (QR/QS) can also be used in the standard
circuit diagram providing the following is observed.
The QS./QR. outputs function inside as isolated contacts.

Connect the test signal outputs T1 to T4 with the inputs in
order to be able to detectperipheral faults such as cross-
circuits between the signal cables. They are not intended
for operating loads.
h
A safety output (QR/QS) can either be used in the safety
circuit diagram or as a non-safety output in the standard
circuit diagram. A double use of this output type causes an
error signal with the circuit diagram safety test as it would
contravene rule number 9 (
of the safety circuit diagram (plausibility check)” on
page 102).
j
Danger!
Device outputs QR and QS that are set by the standard
circuit diagram are not safety outputs and must only be
used for standard tasks. Make sure that these outputs do
not trigger any safety-related actions on the machine or
plant.
