11.2.4.45 Diagnostics value '68.LMY2 +/-Leakage at Y2'
Display range: ±0.000 ... #.### (bar/min)
±0.000 ... #.### (psi/min)
±0.00 ... ##.## (MPa/min)
Purpose: Shows the pressure increase/leakage per minute on actuating pres‐
sure Y2. The value is determined in the controlled state.
Negative values (leakage) can indicate a leak in the pneumatic sys‐
tem.
Positive values (pressure increases) can indicate a pneumatic short
circuit between supply pressure PZ and actuating pressure Y2.
11.2.4.46 Diagnostics value '69.LMY1 - Maximum positive leakage at Y1'
Display range: +0.000 ... #.### (bar/min)
+0.000 ... #.### (psi/min)
+0.00 ... ##.## (MPa/min)
Purpose: The pressure change at Y1 is continuously monitored in the control‐
led state. The maximum pressure increase is displayed.
If a limit de󹪝ned in "U8.LRL" is exceeded, the error code "22" is
shown in the display. A message is entered in the logbook. To reset
the error code, eliminate the leakage. The parameter can also be
reset via HART communication. If you cannot eliminate the
leakage, increase the "U8.LRL" parameter or set the parameter to
0.
11.2.4.47 Diagnostics value '70.LMY2 - Maximum positive leakage at Y2'
Display range: +0.000 ... #.### (bar/min)
+0.000 ... #.### (psi/min)
+0.00 ... ##.## (MPa/min)
Purpose: The pressure change at Y2 is continuously monitored in the control‐
led state. The maximum pressure increase is displayed.
If a limit de󹪝ned in "U8.LRL" is exceeded, the error code "22" is
shown in the display. A message is entered in the logbook. To reset
the error code, eliminate the leakage. The parameter can also be
reset via HART communication. If you cannot eliminate the
leakage, increase the "U8.LRL" parameter or set the parameter to
0.
