Error in the actuator
Despite being disabled, a switching
element of the two-channel actuator
does not switch to the safe state
(e.g., a contact will not open)
No None No No loss of the safety function as the second switching element of the
two-channel actuator can be disabled.
Detect errors using external monitoring.
Implement a restart inhibit in the event of this error.
Please note all errors that can occur in the actuator.
Test the shutdown capability of the actuator at regular intervals.
Actuator cannot be enabled
(e.g., interrupt)
No None No Detect errors using external monitoring. Please note all errors that
can occur in the actuator.
Ensure that this error does not result in delayed system startup.
Other errors
(depending on the actuator)
Please note all errors that can occur in the actuator.
Error in the wiring
Interrupt
Cable interrupt between output and
actuator or between actuator and
ground
No None No Detect errors using external monitoring. Please note all errors that
can occur in the actuator.
Ensure that this error does not result in delayed system startup.
Cross-circuit
Output to output Yes
(condi-
tional)
All OUT
LEDs:
red on
No When the outputs are disabled, a cross-circuit between the outputs
is only detected if the test pulses are enabled. If an error is detected,
the module disables all its outputs.
If the test pulses have been disabled, test the circuit and the external
wiring at regular intervals by enabling the outputs.
Short circuit
Output to ground
or
output to FE
Yes Short circuit
or overload,

No The error is detected in the ON state. The output is disabled (safe
state). The module cannot be switched on again with an edge from
“0” to “1” until the error has been removed and acknowledged.

WARNING: Unexpected machine startup
An operator acknowledgment can result in
unexpected machine startup.
• Please note that an operator acknowledgment
can result in the outputs being re-enabled.
