Explanation
Reset time Ti
Rate time Td
Minimum reaction required of
actual process value within reac-
tion time
Maximum reaction required of
actual process value within reac-
tion time
Reaction time for monitoring
min. or max. reaction of actual
process value
Actual value source of process
controller
Modulating behaviour of PID
controller
Explanation
Activate failure behaviour
Setting the actuator reaction for
active failure behaviour
Failure source (failure reason)
for failure behaviour
Failure operation is only ex-
ecuted after delay time has ex-
pired.
Failure position in percent
Failure position of multiport
valve
Explanation
Failure reaction EMERGENCY.
The EMERGENCY failure reac-
tion defines the actuator beha-
viour once the EMERGENCY
signal is initiated.
Determines the availability of
EMERGENCY behaviour de-
pending on the selector switch
position Local or Remote
