Meaning
The safety sensor has been actuated. This
message is automatically reset if the value
"1" is present for all function inputs moni‐
tored (set as part of configuring).
The protective door is closed.
The lock is engaged.
The lock is released
A cross-circuit was detected at input x.
Only with start type "Monitored start":
The start signal time monitoring element
detected a violation.
is set if:
• A sensor test was not executed in the
case of an active startup test function
• A discrepancy condition violation is
present
• The value "1" is not present simultane‐
ously at all available (parameterized)
function inputs (IN1, ...)
• A signal sequence violation is present
• A cross-circuit is present in the case of
cross-circuit monitoring
The start override time is running.
The feedback circuit signal does not match
the interlock status
The protective door opened when inter‐
lock was active.
