3.1General Description
The vacuum switch and pressure switch versions belonging to the VSi series are referred to
only as the switch below.
The VSi-series switch can be operated in two operating modes.
• Via direct connection to discrete inputs (standard I/O = SIO) or
• Via connection through the communication line (IO-Link class A)
Switching points are indicated using one or two orange LEDs. If the switching point is not active, opera-
tional readiness is indicated by a green LED at switching point 1. The LED for switching point 2 remains
deactivated.
Additionally, a multitude of information and status reports for the switch can be accessed using wireless
communication with NFC (near-field communication).
The parameters can also be set using two buttons on the display version (VSi-…-D). The current system
status and the settings are shown on a display.
The fluid connection offers the opportunity to align the switch in a screwed-in position.
3.2Versions
Each switch has a precise item designation (e.g. VSi-V-D-M8-4) that is composed of the following type

IO-Link Commissioning
EN-US · 30.30.01.00956 · 03 · 05/22 15 / 44
6IO-Link Commissioning
When operating the switch in IO-Link mode (digital communication), the supply voltage, Gnd (ground)
and the C/Q communication cable must be directly connected to the corresponding connections of an IO-
Link master with IO-Link class A ports. When doing so, a new port must be used on the master for each
switch; a junction of several C/Q cables is not possible with only one IO-Link master port.
The IO-Link master must be connected in the configuration of the automation system in the same way as
other fieldbus components. To activate the port for IO-Link communication, a software tool from the re-
spective master manufacturer is usually provided (e.g. Siemens PCT, Beckhoff TwinCAT etc.).
The necessary device description data (IODD) for the switch can be downloaded from our website
www.schmalz.com.
The second output OUT2 for the vacuum switch is deactivated in IO-Link operation.

7Interfaces
7.1Digital Switching Outputs (SIO)
To operate the standard digital inputs of the automation technology or to directly control the electrical
consumers, the switch has two digital outputs.
In the version with an analog output, the functions of switching point 2 or the second digital
switching output are unavailable.
In the delivery state, the signal output OUT 1 is assigned the function switching point 1, parts control, and
the signal output OUT 2 is assigned the switching point 2, leakage monitoring. They are configured in the
EF menu (Extended Functions) via the associated menu items 0u1 and 0u2.
The electrical status of both of the outputs OUT1 and OUT2 thus corresponds with the logical status of
switching points 1 and 2 regardless of the switching point parameters that have been set:
• Switching point mode and switching point logic
• Switching thresholds and hysteresis (function depends on mode set)
• Switch-on and switch-off delay times
• Electrical transistor functions PNP or NPN
The electrical signal outputs are adjustable with regard to the switching behavior on the device. In the EF
menu or via IO-Link, a choice can be made between the PNP and NPN signal types for each signal output.
The setting is independent of the version.
The vacuum switch is factory set to PNP.
7.2Analog output
Only the version VSi-V-SA has an analog output.
The integrated sensor measures the vacuum and proportionally outputs an electrical voltage between 0
and 5V at the analog output (OUT2, PIN 2). 0V corresponds to a vacuum of 0mbar.
7.3IO-Link
The vacuum switch can be operated in IO-Link mode to enable intelligent communication with a con-
troller. The parameters of the vacuum switch can be set remotely using IO-Link mode.
The vacuum switch provides many additional functions besides the two switching signals via the IO-Link
communication.
• The actual measurement value is provided live using the process data.
• Warnings and error statuses that occur are reported to the master via the IO-Link event mechanism.
• More precise information regarding the system status is retrieved using the acyclical communication
channel (known as ISDU parameters).
• Within the framework of the ISDU channel, all settings (e.g. switching point modes and delay times)
for the vacuum switch are read or overwritten.
• In addition to the identification data that can be accessed from the control menu such as the part
number and serial number, additional information regarding the identity of the ejector can be re-
trieved. It also provides memory for user-specific information, for example the installation or storage
site.

7.4Replacement of the Device with a Parameterization Server
The IO-Link protocol provides an automated process for transferring data when a device is replaced. For
this Data storage mechanism, the IO-Link master mirrors all setting parameters for the device in a sepa-
rate non-volatile memory. When a device is swapped for a new one of the same type, the setting parame-
ters for the old device are automatically saved in the new device by the master.
üThe device is operated on a master with IO-Link revision 1.1 or higher.
üThe Data storage feature in the configuration of the IO-Link port is activated.
4Ensure that the new device is restored to the factory settings before it is connected to the IO-Link
master. If necessary, reset the device to the factory settings.
ðThe device parameters are automatically mirrored in the master when the device is configured using
an IO-Link configuration tool.
Changes to the parameters made by a PLC program using a function module are not automatically mir-
rored in the master.
4Manually mirroring data: After changing all required parameters, execute ISDU write access to the
System Command parameter (Index 2) using the Force upload of parameter data into the master
command (numerical value 0x05) (> See ch. (see Data Dictionary in the appendix)).
Use the Parameterization server function of the IO-Link master to ensure that no data is lost
when switching the device.

7.5NFC Interface
NFC (Near Field Communication) refers to a standard for wireless data transfer between different devices
over short distances.
The vacuum switch VSi functions as a passive NFC tag that can be read or written to by a reading device
such as a smartphone or tablet with NFC activated. Access to the parameters of the vacuum switch via NFC
also works without a connected supply voltage.
There are two options for communicating via NFC:
• Read access only can be obtained via a website viewed in a browser. For this, no additional app is
needed. The reading device requires only that NFC and the internet connection are enabled.
• Another option for communication is the “Schmalz ControlRoom” control and service app. This per-
mits not only read access, but also active reconfiguration of the parameters via NFC. The Schmalz
ControlRoom app is available at the Google Play Store.
The following instructions should be followed to ensure the optimum data connection between the NFC
reading device and the vacuum switch VSi:
• In the VSi version, the antenna is located behind the NFC label on the housing
• In the VSi...D display version, the antenna is located directly behind the display
• The mobile device itself must be aligned as parallel as possible to the front of the switch
• The antenna of the mobile device should be positioned in the center of the antenna of the switch
The reading distance is very short for NFC applications. Determine the position of the NFC an-
tenna in the reading device used. If parameters of the device are modified via NFC, then the
power supply must subsequently remain stable for at least three seconds to prevent data loss
(error E01).

8Operating Concept
8.1Manual Operation of the Display Version
The switch is operated using the MODE (1)
and SET (2) buttons.
Settings are configured using software
menus. The operating concept is set up ac-
cording to VDMA 24574-1 and is divided into
three menu levels:
• Basic menu
• Menu for additional functions (EF)
• Info menu (INF)
Setting the switch in the basic menu is usu-
ally sufficient for standard applications.
12
The following information can be shown on the display:
• Actual vacuum/pressure measurement value
• Selected menu item
• Settings
• Error messages
After a parameter is set in the operating menu, the power supply of the switch must remain
stable for at least 3 seconds. Otherwise, there may be a loss of data and the resulting error
E01.
8.2Display of Vacuum and Pressure Values
In the basic operating menu state, the actual measurement value is displayed on the basis of the chosen
display unit. All units are available in millibar, kilo pascal, inch-hg and PSi. The information displayed
varies depending on the device version and the position of the measurement value in the vacuum and
pressure range:
Measure-
ment value
Version V Version P10 Version VP8
mbar kPa inHg psi mbar kPa inHg psi mbar kPa inHg psi
10bar FFF
9bar FFF 9.00 900 266 131 FFF
8bar FFF 8.00 800 236 116 8.00 800 236 116
6bar FFF 6.00 600 177 87 6.00 600 177 87
-800bar 800 80.0 23.6 11.6 -FF 800 80.0 23.6 11.6
-1000bar -FF
With version V, the vacuum value, i.e. the vacuum compared to the ambient air pressure, is displayed as a
positive; in version P10, it is displayed based on the pressure.
In version V8, the pressure is positive and vacuum is negative; however, the positive/negative sign is not
displayed. You can determine whether the value is positive or negative using the table due to the pres-
ence of a decimal point. The switching threshold SPx/FHx and rPx/FLx in the operating menu is displayed
based on the same method.
If an error status is active, it is indicated in the display through a periodic switch with the measurement
value. For recognition purposes, a prefix “E” stands for error, followed by the error number.

One exception is error 7 (operating voltage too low): in this case “E07” will be permanently indicated in
the display and the switch will delay further user entries until the operating voltage has reached the nec-
essary level again.
8.3Navigating in the Menu
You can switch from the home screen to the main menu by pressing the SET BUTTON.
To scroll through the menu press the SET BUTTON.
When you find your desired menu item, select it using the MODE BUTTON.
If there is a submenu (“EF” and “INF”) this can also be browsed in the same manner using the SET BUT-
TON.
You can exit the menu at any point by pressing the SET and MODE buttons.
8.4Editing Parameters
If a menu item has been selected, the current value first appears on the display.
For parameters that can be set, the whole value or lowest number will flash and can be changed by using
the SET BUTTON. When doing so, the possible settings are run through cyclically.
With version VP8, the values of the switching thresholds SPx/FHx and rPx/FLx can be positive (pressure
measurement range) as well as negative (vacuum measurement range). In this case, the desired range for
the new value is set at the start of the editing process. The text [Pr5] for pressure or [vAC] for vacuum
will firstly flash and can be selected accordingly.
For numerical values consisting of 3 numbers, you can use the MODE BUTTON to change to the next
higher number.
At the end of the editing process, press the MODE BUTTON again after the last number. The new value
then appears on the display for 2 seconds without flashing.
If the new value is invalid, the display shows a message and the old value is retained:
• [0or] (out of range) means that the new value is generally outside the value range (e.g. SP1 > 8.0
bar in the VP8 version)
• [1nC] (inconsistent) means that the value overlaps with the current setting of another parameter,
e.g. rP1 > SP1
You can cancel the editing process at any time by pressing the SET and MODE buttons simultaneously.
Example of “Setting a Number Value”:
Changing SP1 from 750mbar to 725mbar with V version
