7.13.5 Reaction monitoring
The AUMATIC controls monitor the actuator reaction via the control unit of
the actuator.
If no reaction is recorded at the output drive of the actuator within a set time
(
REACTION TIME
parameter), the actuator is switched off and the follow-
ing fault signals are given:
.
Status indication
S0
: operation mode OFF/LOCAL =
FLT + NR
.
Status indication
S0/S6
: operation mode REMOTE =
FAULT IND.
.
Status indication
S1
:
INTERNAL FAULT
.
Diagnostics indication
D2
:
NO REACTION
.
The Foundation Fieldbus APVB transducer block signals a fault via
XD_ERROR (Electronics Failure, 20 (0x14)) and XD_ERROR_EXT
(Internal electronics error, 0x00040000), thus generating an operation
mode change of the DOFB or AOFB to the IMan status.
The fault has to be acknowledged. The acknowledgement is made:
.
via the Reset push button in selector switch position LOCAL.
.
via the APPLICATION_RESET Foundation Fieldbus parameter of the
APVB transducer block (index 784).
In case of operation from an intermediate position, reaction monitoring will
only be performed if the actuator has a position feedback.
Switching the reaction monitoring on/off
This value is set in the factory and may not be changed.
