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

    •  

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.

    •  

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).

 

  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.

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.

PRODUCT DESCRIPTION

Humidity/temperature transmitters of the EE31 series  provide multifunctionality, highest accuracy and simple 

installation and maintainance. The modular housing enables a user-friendly operation and a fast replacement 

of the sensor unit for service purposes.By selecting a suitable housing version the EE31 series can be used 

for the entire range of humidity measurement applications:

 

• 

Model A for wall mounting.

   

• 

Model B for duct mounting.

   

  Model D, model H with remote sensing probe

   

 Model E with remote sensing probe for pressure-tight applications up to 20bar 

(300psi)

   

 Model F for wall mounting with rear cable outlet.
