Group objects
21
This group object is enabled via the parameter Valve purge in the Valve output A parameter window unless the Deactivated
option is selected. The status of the valve purge is displayed via this group object.
The status is sent depending on the option selected in the parameter Send group object "Status Valve purge".
Telegram value:
•
0 = Valve purge inactive
•
1 = Valve purge active
22
If there is an active fault on the valve output, a reset can be performed with the telegram value 1 via this group object.
A reset is only successful if the fault has been repaired and is no longer present.
The LED turns off after it is successfully reset.
The fault can also be reset by restarting or by an ETS reset.
The device can be restarted by disconnecting and reconnecting the bus voltage.
Indication by LED only on devices with manual operation.
23
This group object is enabled via the parameter Valve purge in the Valve output A parameter window unless the Deactivated
option is selected.
This group object can initiate a valve purge.
24
This group object is enabled by selecting Yes in the parameter Enable manual valve override.
If manual valve override is enabled, the value in group object Override valve control value is written directly to the
valve output. The value specified by the controller, or specified via a group object Control value in actuator mode,
is overridden.
Telegram value:
•
0: Manual override disabled
•
1: Manual override enabled
When a 0 is received on this group object, manual override is immediately blocked and the value specified by the
controller, or specified via group object Control value in actuator mode, applies again.
25
This group object is enabled by selecting Yes in the parameter Enable manual valve override.
This group object can send a manual valve control value for overriding the valve, e.g. for test purposes.
The value in this group object becomes active only if the override has been enabled by the Enable/disable manual override
valve group object. A block via this group object immediately cancels the overridden value.
A value received in this object is only processed once. If the override is disabled again after the receipt of a value
(Enable/disable manual valve override group object), this value is not set again if the override is activated again.
A new value must be received or have been received again after the disable.
