2Fundamental Safety Instructions
2.1Intended use
The Vacuum/pressure switch is used for measuring and displaying folw or pressure and outputs it propor-
tionally as an electrical voltage from 1 to 5V on an analog output.
This device has been designed, developed and constructed solely for industrial and commercial use. Pri-
vate use is excluded.
The Vacuum/pressure switch is built in accordance with the latest standards of technology and is shipped
in safe condition. However, hazards can arise during use.
Intended use includes the observance of the technical data and the installation and operating instructions
in this manual.
2.2Non-Intended Use
Schmalz accepts no liability for damages caused by the use of the Vacuum/pressure switch for purposes
other than those described under "Intended Use."
Non-intended use includes the following:
• Use in potentially explosive atmospheres
2.3Safety Instructions
WARNING
Use of flammable fluids and/or permeable fluids
They may cause fire, explosion or corrosion.
4Do not use flammable fluids and/or permeable fluids.
2.4Personnel Qualification
Unqualified personnel cannot recognize dangers and are therefore exposed to higher risks!
1. Only instruct qualified personnel to perform the tasks described in these operating instructions.
2. The product may only be operated by persons who have undergone appropriate training.
3. Electrical work and installations may only be carried out by qualified electrical specialists.
4. Assembly and maintenance work must only be carried out by qualified personnel.
2.5Modifications to the Product
Schmalz assumes no liability for consequences of modifications over which it has no control:
1. The product must be operated only in its original condition as delivered.
2. Use only original spare parts from Schmalz.
3. The product must be operated only in perfect condition.

5Installation
5.1Installation Instructions
• Do not use near a surge voltage generated area. Solenoid lifters, high frequency Induction furnaces
and motors, etc. can generate high surge voltages, if using near the sensor will cause the internal
circuit components to deteriorate and cause damages.
• Sensors can not withstand lightning strikes. The product is CE compliant, but can not resist surge
voltage of lightning strikes, take measures to avoid lightening strikes in the system.
• Do not use in an environment where sensors could be splashed by water or oil. Enclosure rating is
IP40, please avoid water or oil splashed environment to prevent adversely effects.
• Do not use in an environment subject to large temperature cycling. Internal components of the sen-
sor will be affected adversely by large heating/cooling cycles other than ordinary changes in temper-
ature.
• Do not mount the product in locations where it is exposed to radiant heat. This could result in dam-
age and/or malfunction.
• Ensure the flow direction of the fluid. Follow the flow direction indicator for installation and piping.
• Flush out all dirt and dust by air blow before connect the piping to the sensor.
• When installation, do not drop, hit or apply excessive shock (100m/s2). Internal damage can cause
malfunction even if the housing appears to be undamaged.
• Do not install multiple products in close proximity. The heat generated from each product could
cause the temperature to rise and change the characteristics of product or deterioration of the plas-
tic parts. Please position the products 10mm apart from each other.
• Hold the sensor body when installing. The tensile strength of the cable is 24.5N and apply excessive
pulling force can cause damage to the sensor.
NOTE
The pressure or flow rate exceeded the specified range
The sensing element may be damaged
4Check the regulator and flow adjustment valve before introducing the fluid.
The sensing element cannot measure properly if foreign matter adheres to it.
On the inlet side, be sure to install an air filter below the filtration level of 10µm.

When measuring the pressure of the inlet side, install a throttle valve or solenoid valve on the
outlet side.

When measuring the pressure of the outlet side, install a throttle valve or solenoid valve on
the inlet side.
5.2Mounting Bracket / Optional Parts
Do not mount the sensor in a place that will be used as a foothold. The product may damage if sit or step
on it accidentally.
The LCD display may be difficult to see at certain angles.
The sensor can be installed horizontally or vertically, but the flow rates may change because of the instal-
lation way of the product or piping.
The tightening torque for screws should be under 0.5 ±0.1Nm.

5.3Piping
Install the pipe by following the arrow indication that shows the air flow direction on the product.
Flow direction
Use straight piping 8cm or longer to connect the Piping Port (Inlet side). If straight piping is not installed,
the accuracy may vary by ± 2% F.S..
Straight Piping: The pipe is without bending and the cross sectional areas of the pipe keeps
the same.

Blow the air to flush out the foreign matters, dust and
etc. before installing the pipe. Uncleaned air may cause
malfunction or damage to the product.
When mounting the fitting, a wrench should be used
on the metal part.
Using on other parts of the product with a wrench may
damage the product.
If the tightening torque is exceeded, the product can
be broken.
If the tightening torque is insufficient, the fitting may
become loose and cause air leakage.
After installation completed, turn on the gas and
power supply for proper operation and leaking test to
confirme whether the installation is correct.
Caution
5.4Electrical Connection
NOTE
Incorrect power supply
Destruction of the integrated electronics
4Operate the product using a power supply unit with protected extra-low voltage
(PELV).
4The system must incorporate safe electrical cut-off of the power supply in compliance
with EN60204.
4Do not connect or disconnect the connector under tension and/or when voltage is ap-
plied.
NOTE
Connect with the power turned on
Damage to the electronics and/or malfunction
4Switch off the power supply before connecting cables!
The folw sensor is supplied with a 6-wire connection cable with open cable ends.
Integrate the folw sensor into your application in accordance with the electrical circuit diagram. The fol-
lowing points must be taken into account for this:
• Check wire color and terminal number when wiring. Incorrect wiring can cause permanent damages
to the sensor, check wire color and terminal number against the manual before wiring.
• Avoid repeatedly bending or stretching the lead wire. It can cause damage to the sheath, or break-
age of the wire.
• Confirm wiring insulation. Please avoid poor insulations (and interference from another circuit, poor
insulation between terminals, etc.) it can lead to over current being applied to the product, causing
damage.
• Do not route wires and cables together with power or high voltage cables. The product may mal-
function due to interference or noise and surge voltage from power and high voltage cables.
• Do not short-circuit the load. When the load is short-circuited, an error will be displayed. But excess
current may cause damage to the sensor.
