1. GENERAL

The manual is a part of the scope of supply and serves to ensure proper handling and optimum functioning of the instrument. For this reason, the manual must be read before start-up. In addition, the manual is for all personnel who require knowledge concerning transport, setup, operation, maintenance and repair. The manual must not be used for the purpose of competition without a written consent from E+E Elektronik® and must also not be forwarded to third parties. Copies for personal use are permitted. All information, technical data and illustrations contained in these instructions are based on information available at the time of publication.

1.1 Symbol assertion

This symbol indicates a safety instruction.

These safety instructions should always be followed carefully. By not following these instructions injuries of persons or material damage could happen. Therefore E+E Elektronik® does not accept liability.

This symbol indicates a note.

These notes should be observed to achieve optimum functioning of the equipment.

1.2 Safety instructions

General Safety Instructions

  •

•Take care when unscrewing the filter cap as the sensor element could be damaged.   •The sensor is an Electro Static Discharge sensitive component (ESD). When touching the sensor

  •Grip sensors only at the lead wires.   •Installation, electrical connection, maintenance and commissioning should be performed by qualified personnel only.

• The devices are constructed for the operation of separated extra-low voltage (SELV).

Excessive mechanical loads and incorrect usage should always be avoided.

element, ESD protective measures should be followed.

Safety instructions for use of the alarm module with voltages >50V

  •

To insulate the optional alarm module from the low-voltage side of the transmitter, the

partition provided for this purpose must be fitted in the lower section.

  •During operation of the instrument the modular housing must be completely closed.   •The protection class of an opened housing corresponds to IP00 and direct contact

with components carrying dangerous voltages is therefore possible. In general, work on live components should be avoided and when absolutely necessary, should be performed by qualified personnel only.

Safety instructions for use of the integrated power supply (option V01)

  •

During operation of the instrument the modular housing must be completely closed.

  •The protection class of an opened housing corresponds to IP00. In general, work on live components

should be avoided and when absolutely necessary, should be performed by qualified personnel only.

  •The bottom part and the middle part of the housing must be grounded during operation.

1.3 Environmental aspects

Equipment from E+E Elektronik® is developed with due consideration to all resultant environmental issues. When you dispose the equipment you should avoid environmental pollution. For disposal of the transmitter the individual components must be sorted with care. The housing consists of recyclable polycarbonate or metal (aluminium, Al Si 9 Cu 3). The electronics must be collected as electronic scrap and disposed of according to the regulations in force.

2. PRODUCT DESCRIPTION

The sensor probe must be mounted horizontally or vertically pointing downwards. Where possible, a drip sheet should be fitted for each mounting.

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!

(-40...356°F)

Hardware

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.

1st step:

Install the probe with the stop valves closed.

2nd step:

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”)

low calibration point:

Hardware

“CALIB LOW”

2-point humidity calibration procedure on the circuit board!

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.
