b5.FACT3 - Factor 3
Adjustment range: 0.1 ... 100.0
Purpose: Use this sub-parameter to set the factor for formation of threshold 1.
Set the factor in a range from '0.1' to '100.0'. The threshold is the
product of 'b2.LIMIT' and 'b5.FACT3'.
The threshold 3 message is displayed when threshold 3 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
Factory setting: 15.0
8.4.3.3 Monitoring/compensation of pneumatic leakage 'C.\\LEAK'
C. LEAK - Monitoring/compensation of pneumatic leakage
Note
Accuracy of results
Note that this monitoring only delivers results in the case of single-acting, spring-loaded
actuators and a setpoint from 5% to 95%.
Note
Activated tight closing/fast closing function
Note that monitoring with an activated '39.YCLS' Tight closing/fast closing with manipulated
variable (Page 153) function only delivers results in the case of a setpoint with the following
values:
● Value for tight closing/fast closing Down (YCDO) +5% to
● value for tight closing/fast closing Up (YCUP) -5%
'40.YCDO' Value for tight closing/fast closing Down (Page 154)
and '41.YCUP' Value for tight closing/fast closing Up (Page 154)
Note
Update of the message
When the leakage has been rectified, the new status is displayed as message after some time.
● To determine the current leakage, start the online leakage test with Diagnostic value
'11.LEAK - Leakage test' (Page 217).
