ABB TZIDC Digital Positioner

ABB TZIDC  Digital Positioner

Introduction

The TZIDC is an intelligent digital positioner for  communication via HART within the positioner  product range. Unsurpassed shock absorption and  vibration compensation from 10 g to 80 Hz  distinguishes the TZIDC from other products and  guarantees reliable operation in nearly any area  under the harshest ambient conditions.

Intended use

Positioning of pneumatically controlled actuators; designed for  mounting on linear and rotary actuators.The device is designed for use exclusively within the stated  values on the name plate and in the data sheet.  

• The maximum operating temperature must not be exceeded.  

• The maximum ambient temperature must not be exceeded.  

• The housing's rating must be observed during operation.

Improper use

The following are considered to be instances of improper use of  the device:

• For use as a climbing aid, for example for mounting  purposes.  

• For use as a bracket for external loads, for example as a  support for piping, etc.  

• Material application, for example by painting over the  housing, name plate or welding/soldering on parts.  

• Material removal, for example by spot drilling the  housing.

General requirements

• The ABB positioner has been approved only for appropriate  and intended use in standard industrial atmospheres. Any  breach of this rule leads to a cancellation of warranty and  manufacturer's responsibility!  

• Make sure that only devices which comply with the types of  protection relevant to the applicable zones and categories  are installed.  

• All electric equipment has to be suited for the respective  intended use.

Use, operation

The TZIDC is approved for proper and intended use only. In case  of non-compliance, the warranty and manufacturer’s liability do  no longer apply!

• Only those auxiliary components which fulfill all the  requirements of European and national standards may be  used in potentially explosive atmospheres.  

• The ambient conditions specified in the operating  instruction must be strictly followed.  

• The TZIDC is approved for proper and intended use in  standard industrial atmospheres only. Where aggressive  substances are present in the air, the manufacturer has to be  consulted.

Commissioning, Installation

The ABB positioner has to be mounted in a major system.  Depending on the degrees of IP-protection, an interval for  cleaning the equipment (dust settlement) has to be defined.  Strict care has to be taken that only devices which comply with  the types of protection relevant to the applicable zones and  categories is installed. When installing the device, the locally  applicable installation regulations, such as EN 60079-14, must be  observed.

Other important facts to be observed:

• The electric circuits of the positioner must be put into  operation in all zones by persons qualified in accordance  with TRBS 1203. The details on the type label are  mandatory for doing this.  

• The device has been designed in accordance with IP 65  (optionally IP 66) and must be protected accordingly  against adverse ambient conditions.  

• The EC Type Examination Certificate has to be taken into  account, including any special conditions defined therein.  

• The device may only be used in accordance with its  intended use.  

• The device may only be connected when de-energized.  

• The potential equalization of the system must be  established in accordance with installation regulations  applicable in the respective country (VDE 0100, part 540,  IEC 364-5-54).  

• Circulating currents must not be guided through the  housing!  

• Make sure that the housing is properly installed and that  its IP rating has not been compromised.
