Intended use
PC 400 EN V1.5_EN Page 6of 16
4 General product information
The device is a particle counter using an embedded laser, which is operated via internal electronics.
The laser radiation outside the device is below the radiation limits of a class 1 laser. The device itself
is powered by a power supply with external safety extra-low voltage (SELV). It consists of a metal
housing. The particle counter forms part of a measuring system for various applications.
5 Intended use
The particle counter PC 400 is used for determination of the particle concentration in gaseous carrier
media. It is equipped with a laser diode as a light source. The particle detection is effected sidewise
via a 90° optics. The transfer of the measured data is effected via the integrated RS 485 interface
(Modbus protocol).
It is designed and constructed exclusively for the intended use described here and may only be used
accordingly.
A check whether the device is suitable for the selected application must be carried out by the user.
The technical data listed in the data sheet are binding.
Improper handling or operation outside the technical specifications is not permitted. Claims of any kind
due to improper use are excluded.
5.1 Important notes
Our particle counters are highly sensitive optoelectronic devices which require a special and careful
handling. Therefore, please read through the following annotations and advices carefully. This will help
you to save unnecessary problems and costs.
Measuring media:
Suitable measuring media are: Air and all other non-explosive, non-corrosive, non-aggressive gases
whose temperature should not exceed 40 °C, as far as the maximum particle concentration (please
see technical data) is not exceeded (in case of doubt please use a dilution factor!!!).
Sensor system:
In case of a nonuse of the device the suction nozzle should be closed by means of a zero filter (HEPA
CAP) or a closing cap in order to avoid a soiling of the sensor system. This especially applies to the
transport and the storage of the instrument.
Please observe the following when putting the device into operation again:
The pump should only be switched on when the closing cap has been removed since this may lead to
damages at the pump. Furthermore, the instrument should not be exposed to any mechanical shock
since this may lead to a misalignment of the optics.
.
Location:
The instrument should be installed at a vibration-free location with a sufficient heat release, extreme
climate conditions (heat, moisture) should be avoided.
6 Service
Our products are thoroughly examined and tested after production. The primary calibration was
carried out with latex particles and the compliance of the calibration is confirmed on the calibration
label on the back side of the instrument.
The annual recalibration of the instruments with latex particles can be carried out either at the
premises of the customer or on our premises.

7 Principles of functioning
The optical particle counters described in this manual use the scattered light effect for determination of
the particle size and the concentration of aerosol particles. The particles are illuminated with the laser
light. The intensity of the scattered light which is emitted by the particle under different angles is
measured and used as a parameter for determination of the particle diameter. As soon as an aerosol
particle passes through the measuring cell its scattered light gets to a photo element (photo diode) via
a collective lens system. The electronic pulse which is generated is strengthened and allocated to a
pre-selected size range in the microprocessor system. The pulses counted in a pre-selected time span
are related to the volume flow of air (28.3 l/min., or 2.83 l/min.).
When evaluating the counted particles mainly two terms are used which require a more detailed
explanation:
- cumulative (cumul.) = the number of particles which are bigger than the particle diameter given in
the respective channel.
- distributive (distr.) = the number of particles which are bigger than the particle diameter given in the
respective channel but smaller than the (bigger) particle diameter given in the next channel.
According to the factory setting PC 400 gives the measured values distributively.

11 Initiation
After removing the transportation packaging please place the particle counter PC 400 at first
horizontally onto a vibration-free surface near a mains socket. However, please avoid lines at which
large electric motors or devices with strong electrical interferences are operated. Please use the
instrument in no case near devices with stray radiances or heat radiation (e. g. blowers and heating
devices).
11.1 Voltage supply
The voltage supply is effected via the mains unit which is included in the shipment.
In case of any voltage supply via third-party mains units please observe the following
requirements: 18…36 VDC / 0,75 A
11.2 Connection to the compressed air system (gas supply system)
The particle counter PC 400 is connected to the compressed air system/gas supply system via the
supplied pressure controller (please see photo below).
11.2.1 Zero test
If a zero test should be carried out before starting the measurement the zero filter has to be inserted
behind the pressure controller before connecting PC 400 to the compressed air system/gas supply
system. This serves for a zero test of the sensor and avoids a pollution of the optics.
Important: The pressure at the particle counter PC 400 is not allowed to exceed 1.6 bar over-
pressure. The pressure has to be reduced correspondingly by means of the supplied pressure
controller.

11.3 Measurement procedure
Before starting the measuring procedure, the zero filter which possibly has been inserted in front of the
PC 400 for zero test has to be removed.
Please observe that no rough objects, smoke (also testing tubes from flow meters) or liquids get into
the optics. The optical system is the most sensitive part of the instrument and has to be disassembled,
cleaned, mounted, adjusted and calibrated completely after the entry of the above mentioned
materials. This time expenditure can be avoided by careful handling. Please avoid an impact of the
instrument by cigarette smoke. Furthermore, please avoid air resp. gas samples which contain more
particles than the specified maximum particle concentration (please see technical data).
The measurement procedure starts immediately after connecting PC 400 to the power supply.
The LED „Power“ (red) and „Laser“ (green) show the proper condition of PC 400.
11.4 Status display
Power: Lightens up if supply voltage is connected
Meas.: Lightens up of the instruments is in measuring mode (counter is active).
If this light expires the particle counter is in the rinsing stage.
Laser: Lightens up if the laser power is within the tolerance.
Flow: The green LED of the three colors luminous row display shows the correctly adjusted
flow (sampling) and the following indications:
green = OK
yellow = within tolerance
red = out of tolerance
