Please read carefully before starting the device!
Attention: Do not exceed a pressure range of > 50 bar with standard version. With spe-
cial versions up to 350 bar.
Observe measuring ranges of the sensor! The probes will be damages if they are
overheated. Observe max. storage and transport temperature as well as max. operating
temperature (e. g. protect measuring instrument from direct sunlight).
The manufacturer cannot be held liable for any damage which occurs as a result of non-
observance or non-compliance with these instructions. Should the device be tampered
with in any matter other than a procedure which is described and specified in the manu-
al, the warranty is cancelled and the manufacturer is exempt from liability.
The device is destined exclusively for the described application.
CS Instruments GmbH offers no guarantee for the suitability for any other purpose and
is not liable for errors which may have slipped into this operation manual. CS Instru-
ments GmbH is also not liable for consequential damage resulting from the delivery, ca-
pability or use of this device.
We offer you to take back the instruments of the instruments family FA 400 which you
would like to dispose of.
Adjustments and calibrations should only be carried out by qualified employees from the
measurement and control technology branch.
Important: Before installation briefly bleed the compressed air in order to remove con-
densate and particles. This prevents soiling of FA 400. Standing air leads to long mea-
suring times.

INSTALLATION
Please note : CS Instruments 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 with measuring chamber to the com-
pessed 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 humid-
ity reading are shorter than in case of a direct mount-
ing.
Directly in the compressed air system
Screw in probe with G 1/2" thread pressure-tight in the
center or at the top of the compressed air pipe. Take
care that measurement is effected close to the com-
pressed air flow. U-bend pipes or non-flowing com-
pressed 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.

DISPLAYFUNCTION
SPEZIAL INDICATIONS
FA 400 is configured to be connected to DS 300. In this mode, alarm function in FA 400
is disabled and will be handled by DS 300
Indicates that an alarm is reached. The relay will be switched and the measurement
value is blinking
Display
FA 400 can display up to 3 measured values. This are temperature, rel. humidity and dew point.
For better reading only one measured value is displayed. The measured values are toggled dur-
ing normal operation mode every 3 seconds.
The following changes an be made:
- Alarm value
- Display of measured value (temperature, rel. humidity and dew point)
- Display contrast
- Display upside down
Settings ex work:
- Dew point in °Ctd
Menu buttons
On the top of FA 400 are the capacitive key buttons to operate the display menu.

DISPLAYFUNCTION
Connection FA 400
After power on, the display will go through an initialisation procedure and will finally show the ac-
tual online value (ex work dew point). Via the configuration menu up to 3 measuring values can
be configured for online display. FA 400 will toggle between the measuring values every three
seconds.
Display current set alarm value
A short click on the “Enter”-button shows the current set alarm value.
Changing of the alarm value see next page.
Slave mode
Changing the settings is only possible with DS 300
Master mode
Changing the settings with pusbuttons FA 400

DISPLAYFUNCTION
Alarm setting
In order to change the alarm value and the configuration, keep the „Enter“ button pressed for 3
seconds. After input of the unlock code the menu begins with alarm setting. The first digit will start
blinking and can be changed with the „Up“ key. Every digit has to be confirmed with the „Enter“
button.
Menu
You can exit the configuration process by pressing and keeping the “Enter” key for 3 sec or no
key event for 20sec. The configuration before this picture will be save and effected late.

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 instrument has been opened - as far as this has not
been mentioned in the instruction manual for maintenance purposes - or if the serial number
in the instrument has been changed, damaged or removed.
The warranty time for the FA 400 is 12 months. If no other definitions are given the
accessory parts have a warranty time of 6 months. 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 packaging 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 even after the warranty time has elapsed. In case of mal-
functions please send us the instrument with a short-form description of the fault. Please do
not forget to indicate your telephone number so that we can call you in case of any
questions.
CALIBRATION/ADJUSTMENT
According to DIN ISO certification of the measuring instruments we recommend to calibrate
and if applicable to adjust the instruments regularly from the manufacturer. The calibration
intervals should comply with your internal specificaton. According to DIN ISO we recom-
mend a calibration interval of one year for the instrument FA 400.
