Connecting test signal outputs
The easySafety devices are provided with 4 test signal
outputs (T1 to T4). These outputs (T1 to T4) generate
periodic test signals that are looped back to an IS... input
and evaluated inside the device. In this way, it is possible to
detect external faults (e.g. cross-circuits).
A test signal T… can be applied to several IS… inputs if
cross-circuits between the supply cables used can be
excluded.

Danger!
Use the test signal outputs exclusively for activating the
inputs. The activation of loads is not permissible.
j
Danger!
Make sure that the test signals are correctly assigned and
that there are no missing signal assignments for the
device's IS safety inputs. Ensure that the multiple use of
test signal outputs does not cause hazardous faults, for
example, because a cross-circuit cannot be detected.
Check the error detection mechanism extensively during
commissioning.
