4.5.4. Parameter window “X: Safety”
The parameter window “X: Safety” in Fig. 4.5.4 will pop out when it is enabled in the parameter
“Function of safety operation is” in Fig. 4.5(2).
Fig. 4.5.4 Parameter window “X: Safety”
There are 2 “Safety Priority x” (x=1,2) in the parameter window “General”.
The parameter defines the valve position triggered by the actuator during safety operation.
There are 2 individual “Safety Priority x” (x=1,2) for every output, and “Safety Priority 2” is prior to
“Safety Priority 1”. That is even if “Safety Priority 1” is triggered at the same time with “Safety Priority 2”,
the contact position will follow the instruction of “Safety Priority 2”.
The priority of the safe operation function is only lower to the forced operation function in the
system.
Parameter “Valve position during safety X operation” (x=1,2)
This parameter defines the valve position that is triggered by the actuator during the safety
operation. Options:
0 % (OFF)
10 % (26)
...
100 % (ON)
Unchange
Unchange: the valve position is unchanged.
At the end of safety operation mode, the valve output status will return to the previous operation.
For example, if the valve position is 40% under safe operation and 60% before operation, the valve
output status will return to 60% after exiting safety operation.
