1 Introduction 1. Introduction 1.1 Instruction manual structure The present manual provides information on installing, operating, troubleshooting the 266 pressure transmitter. Every section of the present manual is specifically dedicated to the specific phase of the transmitter lifecycle starting from the receipt of the transmitter and its identification, passing to the installation, to the electrical connections, to the configuration and to the troubleshooting and maintenance operations.
2.5 Use of instruction For safety reasons, ABB draws your attention to the fact that only Danger – <Serious damage to health/risk to life>. This message sufficiently insulated tools conforming to DIN EN 60900 may be indicates that an imminent risk is present.
The device can be operated at high Warning – Risk to persons pressure and with aggressive media. Any process media released All devices sent back to ABB must be free from any hazardous may cause severe injuries. Depressurize the pipeline/tank before materials (acids, alkalis, solvents, etc.).
3 Transmitter overview 3.2 Range & Span consideration The 2600T Transmitter Specification Sheets provide all information concerning the Range and Span limits in relation to the model and the sensor code. The terminology currently used to define the various parameters is as follows: URL: Upper Range Limit of a specific sensor.
Please refer to the serial number when making enquiries to ABB service department. The same certification plate (ref.A) can be issued for ABB India Limited, 560058 Bangalore, India, with the numbers: The optional additional SST Tag plate (ref. C - code I2) also provides customer tag number and calibrated range.
4 Opening the box 4.2 Optional wired-on SST plate (I1) The 266 transmitter can be supplied with the optional “Wired On Stainless Steel plate” (figure 4) which is permanently laser printed with a custom text specified in phase of order. The available space consists in 4 lines with 32 characters per line.
Optional Vent/drain valves (code V1/V2/V3) on the transmitter following specifications: are located on the sensor flanges. SERIAL\NUMBER ABB S.p.A. The transmitter has to be positioned so that these drain/vent Made in Italy valves will be located higher than the taps on liquid service in...
