Valve outputs | Valve rinsing
Valve rinsing can optionally be started and, if required, stopped using a com-
munication object. If valve rinsing was started by the object, then the actuator
will stop the cycle time of the cyclical valve rinsing operation. The cycle time is
only restarted after the rinsing operation has been fully executed without inter-
ruption or a stop command was received via the object.
Configuring bus-controlled valve rinsing via an object
If necessary, valve rinsing can be started and, optionally, stopped using its own 1-bit
communication object. This means that it is possible to activate a rinsing operation of
the valve controlled by time or an event. It is also possible, for example, to cascade
multiple heating actuators, so that they perform valve rinsing simultaneously (link of
the individual status objects to the input objects of the valve rinsing).
Bus control can only be used if it has been enabled in the ETS.
Valve rinsing must be enabled and a valid rinsing time configured.
￭
Set the parameter "Valve rinsing controllable via object" to "yes". In the case of
the parameter "Object polarity", configure the telegram polarity, thus presetting
whether the bus-controlled starting and stopping, or, alternatively, only start-
ing, is to be possible.
Bus-controlled valve rinsing is enabled. The communication object is visible.
The name of the object is aligned to the setting of the permitted telegram po-
larity ("Start / stop valve rinsing" or "Start valve rinsing"). When a start com-
mand is received, the actuator immediately starts the configured time for a
rinsing operation. The actuator also actively executes valve rinsing if no
higher-priority function is active. If bus-controlled stopping is permitted, then
the actuator will also react to stop commands by immediately interrupting run-
ning rinsing operations.
￭
Set the parameter "Valve rinsing controllable via object" to "no".
Bus-controlled valve rinsing is not available. Valve rinsing can only take place
cyclically.
Updates of the object from "Start" to "Start" or "Stop" to "Stop" do not produce
a reaction. The length of an elapsing valve rinsing operation or the cycle time
of a cyclical valve rinsing operation are not restarted by this.
Bus-controlled valve rinsing via the object can be combined with a cyclical
valve rinsing operation. If valve rinsing was started by the object, then the ac-
tuator will stop the cycle time of the cyclical valve rinsing operation. The cycle
time is only restarted after the rinsing operation has been fully executed
without interruption or a stop command was received via the object.
