The reset to factory settings function does not affect the following elements:
•
The counter readings
•
The zero-point adjustment of the sensor
8.16 Counters
The ejector has three internal, non-erasable counters and three erasable counters.
Counters 1 [
Cc1
] and [
Ct1
] increase with every valid "Suction" signal pulse, and thus count the ejec-
tor's suction cycles.
Counters 2 [
Cc2
] and [
Ct2
] count the suction valve's switching cycles, and counters 3 [
cc3
] and [
Ct3
]
count the CM events.
The average switching frequency can be determined using the difference between counters 1 and 2.

The counters can be displayed or read out from the INF menu using the parameters listed in the table, or
via IO-Link.
Calling up the Counter Values
ü
Select the counter you wish to see in the [
1mf
] menu.

Confirm the parameter by pressing the
button.
ð
The first three decimal places of the counter total will be displayed (the digits x 10
6
). This corre-
sponds to the three-digit block with the highest value.
Use the
button to display the remaining decimal places of the counter total, in order of descending
value. The decimal points show which 3-digit block of the counter total is shown in the display.
The counter total is comprised of the 3-digit blocks taken together:

The current counter total in this example is 48 618 593.
Non-erasable counter readings are saved only every 1000 steps. That means that when the op-
erating voltage is switched off, up to 999 steps of the counter are lost.
