General instructions for integration into the fail-safe program
Monitoring the feedback circuit in the fail-safe controller
The DM-F PROFIsafe fail-safe digital module has an internal function for monitoring the
feedback circuit of the switching contactors. As a result of this function, there is no need for
the circuit state of the contactors to be monitored by the user program in the fail-safe
controller. However, the feedback circuit state is available as an input in the SIMOCODE pro
system and can be processed if required.
Note
Closing the relay enabling circuits
Note that the closure of the relay enabling circuits does not necessarily have to be linked to a
change in the feedback circuit state.
Reason: Motor contactor switchi
ng is also determined by the circuit state of the relay
outputs.
6.7
Interrupt, error, and system messages on DM-F PROFIsafe
Table 6- 4 Messages on the fail-safe DM-F PROFIsafe digital module
Message
Type
Description
DM-F PROFIsafe active
Message
The DM-F PROFIsafe is in the "PROFIsafe active" status.
Monitoring – Interval for
mandatory testing
Message,
warning
The enabling circuits have not been switched off and on again for
longer than the set monitoring time. The relay contact function of the
enabling circuits can only be tested if the contacts are switched.
DM-F safety-related tripping Message,
warning, error
The enabling circuits have been tripped in a safety-related way. The
motor cannot be switched on again until the enabling circuits of the
DM-F module are reclosed.
Wiring Error A wiring error has occurred on the module (short-circuit to ground in
the sensor / feedback circuit). Check the wiring of the sensor circuits
/ feedback circuit and correct the error.
Feedback circuit Warning The DM-F PROFIsafe has detected a fault in the feedback circuit.
The feedback circuit must be closed at the time of switching on.
Check the feedback circuit.
Enabling circuit closed
Status
The enabling circuits are closed.
Incorrect PROFIsafe address or
incorrect PROFIsafe parameters
Status The parameters of the PROFIsafe profile defined in the fail-safe
controller are incorrect / the set PROFIsafe address is not identical to
the configured address (refer to Chapter "Configuring the DM-F
PROFIsafe and integrating it into the fail-safe automation system
using PROFIBUS/PROFIsafe or PROFINET/PROFIsafe (Page 46)").
No module voltage Status The supply voltage on the module is either too low or there is no
voltage.
Check that the A1 / A2 terminals are correctly wired.
The module could be defective. Replace the module (refer to Chapter
"Replacing a DM-F (Page 55)").
