Valve outputs | Valve rinsing
Take command values of last cycle time
into account
Optionally, intelligent cyclical valve rinsing can be additionally activated here. Here,
valve rinsing is only executed repeatedly, if, in the current time cycle, a configured
minimum command value limiting value was not exceeded. It the active command
value exceeds the limiting value, then the actuator will stop the cycle time. The actu-
ator only restarts the cycle time if, in the further course of the command value
change, a command value of "0%" or "OFF" (completely closed) is set. This prevents
valve rinsing if the valve has already run through a sufficiently defined stroke.
If, after exceeding the configured limiting value, the value was not completely closed
at least once (command value "0%" or "OFF"), then no further cyclical valve rinsing
will take place.
Stop valve rinsing from command value of 10...50...100 %
This parameter defines the minimum command value limiting value of the intelligent
valve rinsing. Intelligent valve rinsing is only executed repeatedly, if, in the current
time cycle, a minimum command value limiting value configured here was not ex-
ceeded. It the active command value exceeds the limiting value, then the actuator
will stop the cycle time.
Valve rinsing controllable via 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 cas-
cade 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 here.
Object polarity
This parameter sets the telegram polarity of the object for external valve rinsing. The
name of the object is aligned to the setting of the permitted telegram polarity ("Start /
stop valve rinsing" or "Start valve rinsing"). When a start command 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-con-
trolled stopping is permitted, then the actuator will also react to stop commands by
immediately interrupting running rinsing operations.
