Diagnostic messages of the PM-E F pm DC24V PROFIsafe, causes of errors and
remedies
Fault Possible Causes
Detection
Always Short circuit in the
actuator
Cross circuit in the
actuator
Internal error
Short circuit in P1 and
P2 because actuators
connected to standard
DO modules are not
supplied by means of
the terminal modules of
the standard DO
modules
For output Output stage is
signal "1" overloaded and
only becomes too hot
Always Shutdown due to
violation of upper or
lower temperature limit
value in the module
case
for "1" output Line break
signal only
Always Internal module fault
has occurred
Always Inserted module does
not match
configuration; incorrect
parameter assignment
PROFIsafe address set
incorrectly in the F-
module
Always Supply voltage not
available or too low
(e.g. voltage dip on F-
module, this can also
be caused, among
other things, by a
short-circuit on the
P1/P2 buses.
7.2 PM-E F pm DC24V PROFIsafe Power Module
Corrective Measures
Eliminate the short-circuit.
Eliminate the cross-circuit within 100
hours after the error has occurred.
Replace module
Actuators connected to standard DO
modules are supplied via the terminal
module of the standard DO module;
replace the fuse after a short-circuit
Acknowledge the error within 100 hours
after the error has occurred
Eliminate overload
Check load wiring, check ambient
temperature, check whether permissible
output current is exceeded for the
ambient temperature. Once the fault has
been eliminated, the module must be
removed and inserted, or the power
switched OFF and ON.
Eliminate broken wire, ensure specified
minimum load (see Technical
Specifications)
Replace module
Correct the configuration (compare actual
and preset configuration). Check
communication paths. Correct parameter
assignment
Check whether the PROFIsafe address
on the module matches the configuration
HW Config
in
Check module for correct contact
