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 JUMO and must also not be forwarded to third parties. Copies for personal use are permitted.

The document may contain technical inaccuracies and typographical errors. The content will be revised on a regular basis. These changes will be implemented in later versions. The described products can be improved and changed at any time without prior notice.

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 JUMO does not accept liability.

This symbol indicates a note.

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

1.2 General Safety Instructions

• Excessive mechanical loads and incorrect usage should always be avoided.

• 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 element, ESD protective measures should be followed.

• Installation, electrical connection, maintenance and commissioning should be

performed by qualified personnel only.

2. PRODUCT DESCRIPTION

Specific for the 90.7027 series are the interchangeable sensors with connector. The series also stands for multifunctionality, highest accuracy, easy mounting and service.

Following models are available:

• Model for wall mounting

• Model for wall mounting with rear cable outlet.

Due to its versatility e.g. sensor cable for remote sensor, display, etc. the transmitter can be utilised in many different applications.

The construction of the transmitter makes field and local loop calibration an easy task.

3. INSTALLATION

3.1 Mounting of metal housing

1. Drill the mounting holes according to the mounting template.

2. The bottom part of the housing is mounted with 4 screws (screw

diameter: < 4.2mm

(0.2”) ; not included in the scope of supply).

3. Connection of the transmitter (see chapter 4 "Electrical connections").

4. Mounting of the middle part and cover with 4 screws (included in

the scope of supply).

Transmitter with fixed sensors

RH/T sensor

position 1

Mounting of remote sensors: The sensors can be connected to the housing with

special cables (2, 5 or 10m / 6.6ft, 16.4ft or 32.8ft). Cable length 2m

(6.6ft) (order code: 90/00503577)

5m (16.4ft) (order code: 90/00503578) 10m (32.8ft) (order code: 90/00503579)

The sensor must be mounted horizontally or vertically, pointing downwards. If possible, a dripping water protector should be fitted.

3.2 Mounting of sensors

EMC - Recommendations for Wiring

The indicated EMC guidelines can be guaranteed only in compliance with the sensor cables which are available as accessories.

• Metal housing models must be grounded for safe operation either inside

at the designated points or outside at the mounting plates.

• Seperate cables which generate electromagnetic disturbances from the transmitter

sensing probe cable and analogue output cabels.

• Shields of analogue signal cables should be grounded on one end only - best to the

connected signal processing device. Unshielded cables should be twisted together in order to reduce symmetrical electromagnetic disturbances.

• Keep all cables as short as possible. Loops of cables may reduce EMC performance.

Ground unused wires at both ends. Install all cables as close as possible to ground potential (e.g.: close to the walls, mounting plates or steel structure elements).

6. HUMIDITY-/ TEMPERATURE CALIBRATION

The transmitters 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 for minimum 4 hours in the same room.

• During calibration procedure it is important to keep the temperature constant!

• For calibration the humidity sensor must be stabilised at least 30 minutes in

the reference chamber.

• Replace a used dirty filter cap before calibration!

• The calibration values are only stored in the sensor.

6.1 2-point humidity calibration / 2-point temperature calibration

For accurate adjustment over the whole working range a two point calibration is recommended.

• Start calibration at the low calibration point!

• The difference between the two calibration points should be > 30%RH / > 30 degC (86°F)

2-point humidity calibration / temperature calibration procedure (Start at low

calibration point):

1. At the beginning of a humidity calibration set the jumper to RH Calib / for a

temperature calibration set the jumper to T Calib.

2. Insert the sensor into the reference humidity / reference temperature 1 (low calibration point) and stabilise for at least 30 minutes.

3. BUTTON S2: Pressing the button for 3 seconds starts the procedure for the low calibration point. The calibration mode is indicated by the lit LED "Calib" and by the symbol "CAL<" on the LC display.

4. BUTTON S1 (up) and S2 (down): Pressing the two buttons will adjust the measuring value in steps of 0.1% / 0.1 degC up or down to the reference value. The actual measuring value is indicated on the display or can be measured with the analogue output.

5. BUTTON S1: Pressing the button for 3 seconds the calibration value is stored in the sensor and the procedure is ended. Exiting the calibration mode is indicated by deactivation of the LED "Calib" and the symbol "CAL" on the LC display. BUTTON S2: Pressing the button for 3 seconds the calibration procedure will be ended without storing the calibration values. Exiting the calibration mode is indicated by deactivation of the LED "Calib" and the symbol "CAL" on the LC display.

6. Insert the sensor into reference humidity / reference temperature 2 (high calibration point) and stabilise for minimum 30 min.

7. BUTTON S1: Pressing the button for 3 seconds starts the procedure for the high calibration point. The calibration mode is indicated by the lit LED "Calib" and by the symbol "CAL>" on the LC display.

8. BUTTON S1 (up) and S2 (down): Pressing the two buttons will adjust the measuring value in steps of 0.1% / 0.1 degC up or down to the reference value. The actual measuring value is indicated on the display or can be measured with the analogue output.

9. BUTTON S1: Pressing the button for 3 seconds the calibration value is stored in the sensor and the procedure is ended. Exiting the calibration mode is indicated by deactivation of the LED "Calib" and the symbol "CAL" on the LC display. BUTTON S2: Pressing the button for 3 seconds the calibration procedure will be ended without storing the calibration values. Exiting the calibration mode is indicated by deactivation of the LED "Calib" and the symbol "CAL" on the LC display.

high calibration point:

6.2 1-point humidity calibration / 1-point temperature calibration

When the working range is limited to a certain more narrow range, a calibration at one humidity point / temperature point is sufficient.

• In accordance with the working range, either the high or low calibration point should

be selected. (CP > or < 50% RH / CP > or < 50% of measurement value)

• This calibration causes an extra inaccuracy for the rest of the working range.

1-point humidity calibration / temperature calibration procedure

1. At the beginning of a humidity calibration set the jumper to RH Calib / for a

temperature calibration set the jumper to T Calib.

2. Insert the sensor into the reference humidity / reference temperature (calibration point) and stabilise for at least 30 minutes.

3. BUTTON S1 (Calibration point > 50% RH / > 50% of measurement value): Pressing the button for 3 seconds starts the procedure. The calibration mode is indicated by the lit LED "Calib" and by the symbol "CAL>" on the LC display.

or BUTTON S2 (Calibration point < 50% RH / < 50% of measurement value): Pressing

the button for 3 seconds starts the procedure. The calibration mode is indicated by the lit LED "Calib" and by the symbol "CAL<" on the LC display.

6.3 Resetting the customer calibration to the factory calibration:

BUTTON S1 and S2: To reset the RH or T values, the jumper has to be set on the

respective location before starting the factory calibration. In neutral mode pressing both buttons simultaneously for 5 seconds customer calibration settings are reset to factory calibration. A short flash of the LED "Calib" indicates the reset.
