General Description of Functions
EN-US · 30.30.01.02084 · 02 · 12/20 35 / 72
Leakage L < permitted value -L- Leakage L > permitted value -L-
If the leakage is lower than the set value, the
vacuum continues to fall until it reaches the
vacuum limit value H1-h1, and the ejector be-
gins with suction again (normal control
mode).
The condition monitoring warning is not acti-
vated and there is no effect on the system
status light. If the leakage is higher than the value, the
ejector readjusts immediately.
If the permitted leakage is exceeded twice,
the ejector switches to continuous suction.
The condition monitoring warning is acti-
vated and the system status light switches to
yellow.

Dynamic pressure monitoring:
If possible, a dynamic pressure measurement is taken at the start of every suction cycle. The result of this
measurement is compared to the vacuum limit values set for H1 and H2.
If the dynamic pressure is greater than (H2 - h2) but less than H1, the corresponding condition monitoring
warning will be set and the system status light will switch to yellow.
Leakage level evaluation:
This function determines the average leakage during the last suction cycle, divides it into subareas and
makes it available as a parameter via IO-Link.
Autoset
The CM Autoset IO-Link function in the process output data allows the condition monitoring parameters
for maximum permitted leakage [
-L-
] and the evacuation time [
t-1
] to be set automatically. The ac-
tual values from the last suction cycle are combined with additional tolerance and stored.
7.25.2 Energy Monitoring (EM)
To optimize the energy efficiency of the vacuum gripping systems, the ejector provides functions for mea-
suring and displaying energy consumption.
Percentage-based air consumption measurement:
The ejector calculates the air consumption from the last suction cycle as a percentage. This value corre-
sponds to the ratio for the full duration of the suction cycle and the active suction and blow off times.
Absolute air consumption volume:
An externally recorded pressure value can be supplied using the IO-Link process data. If this value is avail-
able, not only a percentage-based air consumption measurement, but also an absolute air consumption
measurement can be performed. The actual air consumption of a suction cycle is calculated taking the sys-
tem pressure and nozzle size into account.
