Monitoring the upper endstop 'G.\\OPEN'

G. OPEN - Monitoring the upper endstop
Note
Fault detection
Monitoring the 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.

The '52.XDIAG' Activating for extended diagnostics (Page 174)
parameter is set to 'On1', 'On2' or 'On3'.
The '39.YCLS' Tight closing with manipulated variable (Page 166)
parameter is set to 'uP' or 'uP do'.
• OFF
• On
Use this parameter to activate continuous monitoring of the upper
endstop. The monitoring is executed whenever the valve is in the
'Upper tight closing' position. It checks whether the upper endstop
has changed compared to its value during initialization. Monitoring
is performed in three steps. Set the following sub-parameters ap-
propriately. To activate monitoring, set the parameter to 'On'. Sub-
parameters are displayed.
The value is displayed in Diagnostic value '19.OPEN - Upper end-
stop' (Page 216). The positioner triggers a message if the current
value exceeds one of the three thresholds.
OFF
0.1 ... 10.0
Use this sub-parameter to set threshold 1 for the upper endstop in
percent. Set the threshold in a range from '0.1' to '10.0'.
The positioner triggers a message if the difference between the
upper endstop and the initialization value overshoots threshold 1.
The process to activate and display this message is described in
the 'XDIAG' parameter.
