Bit 0: Setpoint received/control value received
This bit indicates whether or not the valve received a valid control value.
–
0: Setpoint/control value received
–
1: Setpoint/control value not received
Note
This bit retains the value 0 during the entire run time if cyclical monitoring is not used (for the operating
mode in controller mode or for the control value in actuator mode), because no cycle time was defined
during which a new value must be received.
•
Bit 1: Output error
The bit indicates whether there is an error at the valve output. This may be a short circuit or overload.
–
0: No error
–
1: Error at output
•
Bit 2: Forced operation
Indicates whether forced operation is active or not.
–
0: Forced operation inactive
–

Fault: valve output
Channel – Valve A
1 bit
DPT 1.002
C, R, T
This group object is enabled as along as the valve output has not been parametrized with
Deactivated
.
If there is a fault on the output, e.g. due to short circuit or overloading, the valve selector's LED and, if a
channel is selected, the "Open" LED flash. The group object simultaneously sends a telegram with the value
1.
The output is switched off in the event of a fault.
The group object value is 0 after the fault has been remedied.
Note
Indication by LED only on devices with manual operation.
