General Description of Functions

• The pneumatic state of the ejector changes as follows:
– For the NO-type ejector, the ejector switches to the “suction” operating state
– For the NC-type ejector, the ejector switches to the “pneumatically OFF” operating state
7.9 Evaluating the Inlet Pressure
The available supply pressure level in the system cannot be measured by the ejector itself. However, the
current measured value for the inlet pressure can be transmitted to the ejector from the system controller
via IO-Link. In this case, the ejector evaluates the pressure level and activates a condition monitoring
warning if the pressure level is not optimal. If there is a significant deviation, an error message is also gen-
erated.
A pressure level must also be transferred to enable the volume of compressed air consumed in the suction
cycle to be estimated in the area of energy monitoring.
7.10 Calibrating the Vacuum Sensor
As the production conditions for the internally integrated vacuum sensor can vary, we recommend cali-
brating the sensor once it is installed in the ejector. To calibrate the vacuum sensor, the system's vacuum
circuit must be open to the atmosphere.
The function for zero-point adjustment of the sensor is performed in the main menu under the parameter
CAL
or using IO-Link.
1. Press the button
ð The menu changes to input
2. Press the or button until
cal
appears on the display
3. Confirm with the button
4. When
YE5
appears, press the button to confirm.
ð The vacuum sensor is now calibrated.
A zero offset is only possible in the range of ± 3% around the theoretical zero position.
When the permissible limit is exceeded by ±3%, error code
E03
will appear on the display.
7.11 Signal Output
The ejector has a signal output. The signal output can be configured using the corresponding menu item.
The signal output OUT can be switched between [
no
] (normally open) and [
nc
] (normally closed) con-
tact. You can switch it in the configuration menu using the [
0-2
] menu item or set it via IO-Link. The
function of the limit value H2/h2 (“Part Present” check) is assigned to the signal output OUT.
The signal output is switched on or off when the system vacuum is higher or lower than the relevant
threshold value.
The output type parameter can be used to switch between PNP and NPN. The signal inputs are also con-
figured with this function. This setting can be switched using the [
tYP
] menu item in the configuration
menu or via IO-Link.
7.12 Signal Type
The signal type, or the switching behavior (PNP or NPN) of the electrical signal inputs and the signal out-
put, can be set on the device and therefore does not depend on the version. You can switch this setting
using the [
tYP
] menu item in the configuration menu or via IO-Link. The ejector is factory set to PNP.
