Measuring the evacuation time t1:
The interval between reaching the switching points SP2 and SP1 is measured (in ms).
If the measured evacuation time t1 (from SP2 to SP1) exceeds the specified value, the “Evacuation time
longer than t-1” condition monitoring warning is triggered and the system status light switches to yellow.
The specified value for the max. permitted evacuation time can be set in the EF menu with the parameter
[
t-1
] or via IO-Link [0x006B]. Setting the value to [
000
] (= off) deactivates monitoring. The maximum
permitted evacuation time setting is 9.99 s.

Measuring the leakage:
In control mode ([
ctr
] = [
on5
] or [
on
]), the vacuum drop/leakage over a certain period of time is mea-
sured (as vacuum drop per time unit in mbar/s) after the air saving function has interrupted suction be-
cause switching point H1 has been reached.
The measured leakage value "L" in mbar/s can be queried via IO-Link.
Evaluating the Leakage Level
In control mode ([
ctr
] = [
on5
]), the loss of vacuum within a certain period is monitored (mbar/s).
Evaluation of the leakage level differentiates between two states:
