Safety
These operating instructions contain important
information about the use of the vacuum sensor.
Please read them carefully and keep them in a safe
place for future reference.
Do not attempt to connect and use the vacuum
sensor before you have read and understood
these operating instructions.
Always comply with the following instructions and
observe the safety notes and warnings.
Warnings:
Operation outside the specified performance limits
is forbidden, since this could result in malfunction or
even destruction of the sensor!
The sensor may not be used in explosion-risk areas,
since this could result in fires or explosions!
The vacuum sensor may not be opened for any
reason, since this could result in damage to the
sensor and/or injuries to the person opening it!
The unit may only be run via power
supply units with protected extra-low voltage
(PELV) and safe electrical cut-off of the
operating voltage, in accordance
with EN60204.
PELV
Caution:
Do not carry the sensor by its cable or pull the cable in
order to remove the sensor from its installation position.
Ensure that the supply voltage is switched off before
installing the sensor.
Do not use the sensor in locations where it may be
subjected to splashwater.
Do not insert any objects (such as wires, tools, etc.) into
the vacuum connector of the sensor.

Installation
Warning:
The sensor may be installed only by a suitably qualified
persons.
General safety regulations, EN standards and VDE
regulations must be observed.
Note:
The maximum permissible length of the cables for the
supply voltage and the analog output signal of the
sensor is 30m in each case.
In order to avoid interference, these cable should be
kept as short as possible.
The shield of the cables should be connected to an
interference-free ground potential. The shield is not
connected inside the sensor.
The vacuum sensors of the VS-V-S... series are
connected as follows:

Caution:
The following maximum tightening torques may not be
exceeded:
VS-V-S...-M3: 0,5 Nm
VS-V-S...-M5: 1 Nm
The force for screwing in the M3 or M5 adapter may be
applied only to the flats on the adapter!
Screwing in the sensor by applying force directly to its
casing is not permitted, since this may result in leaks and
irreversible damage to the sensor.
Operation
The vacuum sensors of the VS-V-S... series are designed
only for operation with a vacuum (referred to atmospheric
pressure).
Pressures of up to 5 bar will not damage the sensor, but
may have negative effects on its accuracy and/or operating
lifetime.
The pressure resistance specified in the technical data is
the maximum pressure at which the sensor will not be
destroyed. Nevertheless, such a pressure can affect the
accuracy and the lifetime of the sensor!
Caution:
When operated at high ambient temperatures and a low
load
impedance,
the
vacuum
sensors
may
temperatures of more than 60°C and may thus cause
burns if touched!
Notes:
VS-V-SA-...
:
We

that

VS-V-SD60-... :
If used for switching inductive loads,
a suitable recovery diode should be
provided.
