INTRODUCTION
Dear Customer,
thank you for choosing the FA 510. Please read these installation and operating instructions
carefully before installation and commissioning and follow our instructions. The proper
functioning of the FA 510 and safe operation can only be ensured if the regulations and
instructions described are strictly observed.
Intended Use
The dew point sensor is intended for measuring the dew point or the pressure dew point in
clean, dry and oil-free gases and compressed air.
The user must check whether the instrument is suitable for the selected application. It must
be ensured that the medium is compatible with the wetted parts. The technical data listed in
the data sheet are obligatory.
Improper handling or operation outside the technical specifications is not permitted. Claims of
any kind based on improper use are excluded.

NOTES ON SAFETY
Read these operating instructions carefully before installing the FA 510.
Failure to observe the instructions contained herein, in particular the
safety instructions, may result in hazards to personnel, equipment and
systems..
x The product may only be used in accordance with its intended purpose.
x Installation of the dew point sensor and maintenance work may only be carried
out by trained personnel.
x Installation and service work must be carried out in a de-energized state.
x The applicable safety regulations must be observed!
x All work on the compressed air network must only be carried out in a
depressurized state.
x Attention: Do not exceed the pressure range > 50 bar for the standard version.
x Observe the measuring ranges of the sensor!
Overheating will destroy the sensors.
x Observe the permissible storage and transport temperature as well as the
permissible operating temperature (e.g. protect the measuring instrument from
direct sunlight).
x Opening the instrument, improper handling or use of force will void all warranty
claims!
x Important: Before installation, briefly allow compressed air to flow off to remove
condensate and particles, this will prevent soiling of the FA 510.
x Standing air leads to long measuring times
DESCRIPTION
The FA 510 dew point sensor enables a reliable and long-term stable monitoring of the dew
point in industrial applications. The FA 510 features improved stability.
When mounting FA 510 into compressed air systems the pressure dew point (dew point
under pressure) up to 50 bar (in the special version up to 350 bar) is measured directly.
When mounting FA 510 in atmospheric conditions (ambient pressure) or in the flow off sector
(relaxed air) of compressed air systems the atmospheric dew point is measured.
Advantages:
x Dew point sensor for very low dew points down to -80 °Ctd
x Extremely long-term stable due to internal automatic calibration
x IP 65 housing grants a reliable protection in extreme industrial conditions
x Very fast response time
x Installable in the dryer by means of G 1/2" thread, optional UNF 5/8” or NPT ½”
x High accuracy of r 2 °Ctd
x Calibration on location and testing with CS control and calibration set (PC connection
set)
Programming via Software.
With the CS Service Software incl. USB / Modbus Adapter the Modbus settings, the scaling of the
Analogue output and the assignment of the measurement values could be set.
- Analogue output 4…20 mA scalable
- Switching between °Ctd,°Ftd, % RH, °C, °F, g/m³, mg/m³, g/kg, ppm, and so on
- Calibration and adjustment
- Sensor diagnosis
- Read-out of service data

INSTALLATION
x The direct installation of the sensor
is only allowed in the unpressurized state
of the system
x • The sensor must be tightened with a torque of 25 - 30 Nm.
x Tightness of the connection must be checked and ensured.
x
It is not permitted to use a sealing ring with a NPT 1/2“ thread. Appropriate
PTFE sealing tape or sealant should be used instead
Please note: CS recommends the indirect installation with measuring chamber
Advantage: Easy mounting and dismounting of the probe without interruption of the line.
Quick response time due to quick coupling. Optimum sensor protection.
Indirectly in the compressed air system
Connect probe wi
th measuring chamber to the
compressed air
pipe by means of a quick coupling.
In
case of compressed air containing oil and dirt particles
a pre
-
filter should be installed in front of the measuring
chamber
.
Compressed air flows continuously (at 7 bar
approx. 1 l/min expanded) in the capillary pipe of the
measuring chamber. The reaction times for the humidity
reading are shorter than in case of a direct mounting.
Directly in the compressed air system
Screw in probe with G 1/2" thread pressure
-tigh
t in the
center or at the top of the compressed air pipe. Take
care that measurement is effected close to the
compressed air flow. U
-bend pipes or non-flowing
compressed air
,
result in very slow reaction times for
the moisture reading
.
Measurable gases
In general, humidity can be measured in all non
-
corrosive gases.
In case of measurements in
corrosive gases please consult CS Instruments GmbH.

Modbus
The dew point sensor FA 510 comes with a Modbus RTU Interface.
Before commissioning of the sensor the communication parameters
Modbus ID, Baudrate, Parity und Stop bit
must be set in order to ensure the communication with the Modbus master.
The adjustment can be done either with the CS Instruments PC service software, DS 400, DS
500 and the hand-held instrument PI 500 done.
Modbus communication default values:
x Modbus ID : 1 (1 -247)
x Baudrate: 19200 bps (1200,2400, 4800, 9600, 19200, 38400 bps)
x Parity: even (none, even, odd)
x Stoppbit: 1 (1,2)
Supported are following functioncodes:
x Function code 03: Read Holding Register
x Function code 16: Write multiple Register

CALIBRATION/ADJUSTMENT
From the manufacturer
According to DIN ISO certification of the measuring instruments we recommend regular
calibration and, if necessary, adjustment of the instrument by the manufacturer. The
calibration cycles should fit your internal scheme. In the course of the DIN ISO certification,
we recommend for FA 510 a calibration cycle of one year. If requested we can carry out the
calibration on your premises.
WARRANTY
If you have reason for complaint, we will of course repair any faults free of charge if it can be
proven that they are manufacturing faults. The fault should be reported immediately after it
has been found and within the warranty time guaranteed by us. Excluded from this warranty
is damage caused by improper use and non-adherence to the instruction manual.
The warranty is also cancelled once the measuring instrument has been opened provided
this is not described in the instruction manual for maintenance purposes. This is also the
case if the serial number has been changed, damaged or removed.
The warranty time for FA 510 is 12 months for the instrument and 6 months for accessories if
no other terms are agreed upon. Warranty services do not extend the warranty time.
If in addition to the warranty service necessary repairs, adjustments or similar are carried out,
the warranty services are free of charge but there is a charge for other services such as
transport and packing costs. Other claims, especially those for damage occurring outside the
instrument are not included unless responsibility is legally binding.
After-sales service after the warranty time has elapsed
We are, of course, there for you after the warranty time has elapsed. In the case of function
faults please send us your measuring instrument with a brief description of the defect. Please
also indicate your telephone number so that we can contact you if necessary.
