'48._TIM' Monitoring time for setting of fault message "Control deviation"

Possible settings:
Purpose:
Factory setting:
Note
Activated tight closing function
If the tight closing function is activated, then for parameter "49.
control deviation is turned off in the appropriate overflow direction. Here, "YCDO: < 0 %" and
"YCUP: > 100 %" apply. This functionality is especially advantageous for valves with lining.
For long-term monitoring of the endstop positions, we recommend activating the parameters
"F. ZERO" and G. OPEN".

'49._LIM' Response threshold for fault message "Control deviation"

Possible settings:
Purpose:
Factory setting:
172
• Auto
• 0 ... 100
The "48. TIM" parameter is used to set the time in seconds within
which the positioner must have reached the regulated condition.
The corresponding response threshold is specified in the "49.
LIM" parameter.
When the configured time is exceeded, the fault message output is
set.
Auto
• Auto
• 0 ... 100
This parameter is used to set a value for the permissible size of the
control deviation to trigger a fault message. The value is given in
percent.
If the parameters "48. TIM" and "49. LIM" are set to "Auto", then
the fault message is set if the slow step zone is not reached within
a certain period of time. Within 5 to 95% of the actuator travel, this
time is twice the initialization travel time, and ten times the initializa-
tion travel time outside of 10 to 90%.
