Monitoring the upper endstop 'G.\\OPEN'

G. OPEN - Monitoring of upper endstop
Note
Fault detection
Monitoring of upper endstop not only responds to faults in the valve. If the limit thresholds of the
upper endstop are exceeded due to misalignment of the position feedback, the misalignment
also triggers a message.
Requirement:
Possible settings:

0.1 ... 10.0
Use this sub-parameter to set threshold 2 for the lower endstop in
percent. Set the threshold in a range from '0.1' to '10.0'.
The positioner triggers a threshold 2 message if the difference be‐
tween the lower endstop and the initialization value undershoots
threshold 2. This message is only output if threshold 3 is not un‐
dershot at the same time. The process to activate and display this
message is described in the 'XDIAG' parameter.
2.0
0.1 ... 10.0
Use this sub-parameter to set threshold 3 for the lower endstop in
percent. Set the threshold in a range from '0.1' to '10.0'.
The positioner triggers a threshold 3 message if the difference be‐
tween the lower endstop and the initialization value undershoots
threshold 3. The process to activate and display this message is
described in the 'XDIAG' parameter.
4.0
The '52.XDIAG' Activating for extended diagnostics (Page 162) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
The '39.YCLS' Tight closing/fast closing with manipulated variable
(Page 153) parameter is set to one of the following values: 'uP',
'uP do', 'Fu', 'Fu Fd', 'uP Fd', 'Fu do'
