Fig. 4.5.2 Parameter window “X: Forced”
In the forced operation mode, the channel is forced to switch to the set position.
The forced operation mode has the highest priority, all operations except forced operation will be
ignored.
This mode can be activated through the communication object "Forced operation," = "1" and ends
when "Forced operation," = "0".
Parameter “Valve position during forced operation”
This parameter defines the valve position that is triggered by the actuator during the forced
operation. Options:
0 % (OFF)
10 % (26)
...
90 % (230)
100 % (ON)
Unchange
Unchange: the valve position is unchanged.
When the forced operation is exited, the valve output is going back to the previous operation. For
example, the valve position under the forced operation is 40%, and the previous operation is 60%. After
exiting the forced operation, the valve output will return to the 60% valve position.
During forced operation, monitoring time of the monitor is still continuous, and when the
monitoring time is up, an error report will be sent, but the action under the fault cannot be
executed, and it can only be executed after the forced operation is exited. During the forced
operation, the received control telegram of common operation will be recorded.
