10.4.2.16 Description of parameters 48

48.

TIM - Monitoring time for setting of fault messages

This 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.

Note

Activated tight closing function

If the tight closing function is activated, then for parameter "49.

LIM" the monitoring of

regulation deviation is turned off in the appropriate overflow direction. Here, "YCDO: < 0 %"

and "YCUP: > 100 %" apply. This functionality is especially advantageous for valves with soft

seats. For a long-term monitoring of the end stop positions, we recommend activating the

parameters "F.

ZERO" and G. OPEN".

10.4.2.17 Description of parameters 49

49.

LIM - Response threshold of fault message

This parameter is used to set a value for the permissible size of the regulation 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 motion zone is not reached within a certain period of time. The setting "Auto" is the

factory setting. Within 5 to 95% of the actuator travel, this time is twice the initialization set

time, and ten times the initialization set time outside of 10 to 90%.
