General safety instructions for installation

Because the sensing probe can be exposed to very high
pressures in the measurement environment, there is the risk of
sudden, unintentional expulsion of the probe during or after
improper installation. Therefore, special precautions should be
taken when working on the sensing probe or in its vicinity.
Bending over the sensing probe should be avoided under
any circumstances!

During the installation of the sensor probe, make sure that
the surface of the sensing probe is not damaged! Damaging
the probe could lead to damaged seals (consequence:
leakage and pressure loss) and to problems during removal
(jamming).

Installation of the probe directly in the process

For direct probe installation, a stop valve should be provided on both
sides of the probe insert. This allows the sensor probe to be removed for
maintenance and calibration without any problems.

If the sensor probe is installed in a pressure chamber, make sure that the
pressure in the chamber and the ambient pressure are in equilibrium
before you remove the probe.

The temperature during installation may not vary more than ±4°C

(±72°F)

from the operating temperature.

1st step:

Install the probe with the stop valves closed.

2nd step:

Insert the sensor probe into the process.

3rd step:

To ensure a secure installation of the probe, the lock nut must be
tightened to a defined torque of 30 Nm.
If no torque-spanner is available tighten the lock nut by hand
as far as possible. Continue to turn with an open-ended spanner ~50°.

7. HUMIDITY/TEMPERATURE CALIBRATION

The EE31 transmitter series can be calibrated in two ways.

- 1-point humidity/temperature calibration: quick and simple calibration on a defined

humidity/temperature point (working point).

- 2-point humidity/temperature calibration: simple calibration for accurate measuring results

over the whole humidity/temperature working range.

 • To reach a temperature balance it is recommended to keep the transmitter and the

reference chamber (e.g. HUMOR 20,...) for minimum 4 hours in the same room.

 •During stabilisation period and calibration procedure it is important to keep the tempe-

rature constant in the reference climate chamber.

 •For calibration the humidity sensor probe must be stabilised at least 20 minutes into

the reference chamber.

 •Replace a used dirty filter cap before calibration!

7.1 2-point humidity calibration

For accurate adjustment over the whole working range or in case of sensor exchanges a
two point calibration is recommended.

 •Start calibration at the low humidity calibration point!

•The humidity difference between the two points should be > 30%RH

•Low humidity point < high humidity point

•Two point calibration may be performed directly on the circuit board, or for

convenience, using the configuration software supplied (for more details, see
Configuration Software, chapter 5.4 ”Calibration”)

1. Insert the sensor probe into the reference humidity 1 (low
calibration point) and stabilise for at least 20 minutes.

2. BUTTON S2: Pressing the button for 5 seconds starts the
procedure for the calibration mode RH. The calibration mode is
indicated by the lit LED "D2" on the circuit board.

3. BUTTON S2: Pressing the button for 5 seconds starts the
procedure for the low calibration point. The calibration mode is
indicated by the lit LED "D2" and the symbol "CALIB LOW" will
appear on the optional LC display.

4. BUTTON S1 (up) and S2 (down): Pressing one of the two
buttons will adjust the measuring value in steps of 0.1% up or
down to the reference value. The actual measuring value is
indicated on the display or can be measured with the analogue
output. As soon as the measured value is changed, "D1" is
flashing.

5. BUTTON S1 (store): Pressing the button for 5 seconds
stores the calibration value and the procedure is ended. LED
"D2" flashes to indicate exiting of the calibration mode and the
symbol "CALIB LOW" will disappear from the optional LC dis­play.
BUTTON S2 (cancel): Pressing the button for 5 seconds the
calibration procedure will be ended without storing the
calibration values. LED "D2" flashes to indicate exiting of the
calibration mode and the symbol "CALIB LOW" will
disappear from the optional LC display.

9.2.3 Ethernet-interface

9.2.3.1 ComCenter

ComCenter (Communication Center) software is the communication link between the
transmitter, the Ethernet-network and the existing EE31 configuration-, data logging- and
visualization software.

The ComCenter provides the following functions:

Discovery tool:
ComCenter supports the detection and administration (Web-Interface) of all transmitters
in the network.

Creation of virtual interfaces (Com-Ports):
ComCenter allows to assign each and every detected IP-address (e.g. transmitter) with a
corresponding virtual interface (Com-Port). With MS Windows® not more than 255 virtual
Com-Ports are possible!

Communication with existing EE31 configuration-, data logging and visualization software:
The created virtual Com-Ports can be addressed by the existing EE31 configuration-, data
logging and visualization software, as long as the ComCenter software is running (active).

9.2.3.2 Installation of the ComCenter

- Insert Ethernet CD-Rom into your
CD-ROM drive

- Choose "Install ComCenter Ethernet
Software"

- Run the setup.exe

- Choose language and follow the
installation wizard

- Choose mode of IP-address assignment (DHCP /STATIC) by jumper setting at the
Ethernet module.

DHCP:

- Change jumper setting to DHCP.

- Press reset-button for 3-5 seconds (LNK - LED temporary off).

- Ethernet module changes to DHCP - mode and requests an IP - address from the
DHCP server.

- Transmitter will be detected as soon as ComCenter is active.

STATIC:

- Default jumper setting is STATIC.

- Factory settings for the transmitters are the static IP - address 192.168.0.64 with the
subnet-mask 255.255.255.0

- Networking settings of the used personal computer might need to be changed in order
to use same subnet-mask (255.255.255.0) as the connected transmitter.

Edit COM Port assignment

Enter a desired Com-Port number (1...255). The Com-Port number will be
assigned to the corresponding IP-address.

Note:
If a number of an existing Hardware Com-Port
(COM1, COM2) is entered, than this will be
assigned. Otherwise a virtual Com-Port will be
created.

Attention:
ComCenter needs to be active (running) as long as the virtual Com-Ports are
in use!
If the ComCenter window is minimized, it will be hidden in the "System Tray"
(right bottom, next to the system time), but it remains active (running)!

5.4 Calibration

In addition to the manual calibration procedure on the circuit board (see
Hardware, chapter 7 “Humidity/Temperature Calibration”), new calibrations can be
performed using the EE31 software.

Note: A two-point calibration for temperature is only possible on the circuit board
and is not supported by the software.

1-point calibration Humidity: Fast and easy calibration for accurate measurement results at a defined working
point (humidity point).

For calibration procedure see Hardware, chapter 7. “Humidity/Temperature Calibration”

1) Stabilise the probe of the desired humidity for min. 30 minutes.

2) Click on the Humidity "1-point calibration" button. The measured values will
now appear in both input fields.

3) Replace the value in the input field "Humidity Reading" with the reference
humidity (value of the saline solution or display of HUMOR 20).

4) By clicking on "Save", the humidity reading for the transmitter will be
adjusted to the reference humidity.

5.3 Sensor / Probe Replacement
In case of sensor or probe replacement, a costumer calibration has to be done.

Replacement -
Humidity Sensor (RH): 1) Replace the humidity sensor by a new one
(see Hardware, chapter 8.1 Sensor Replacement).

2) Run the humidity calibration (see chapter 5.4).

Replacement - Probe (RH & T): 1) Replace the humidity sensor by a new one
(see Hardware, chapter 8.2 Probe Replacement.

2) Run the humidity and temperature calibration (see chapter 5.4)

37

2-point calibration Humidity: Calibration for accurate results over the entire measurement range.

For calibration procedure, see Hardware, chapter 7 “Humidity/Temperature
Calibration”.

1) Place the probe at the reference humidity (lower point).

2) Click on the Humidity Two-Point Calibration button.
(In a separate window, the measured values will appear in both input fields)

3) Replace the value in the input field "Humidity Reading" with the reference
humidity. (Value of the saline solution or display of HUMOR 20)

4) By clicking on "Save", the humidity reading of the transmitter will be adjusted
to the reference humidity. Now the 30-minute stabilisation period starts.

5) Place the probe at the reference humidity (high point).
