IFT 3000 INTELLIGENT FIELD TRANSMITTER

DESCRIPTION

Read the “Safety instructions for the wiring and installation of this appara- tus” at the front of this Instruction Bulletin. Failure to follow the safety instructions could result in serious injury or death.

E-1 DESCRIPTION

The Rosemount IFT 3000 Intelligent Field Transmitter (IFT), Figure E-1,provides all nec- essary intelligence for controlling a probe and the optional Multiprobe Calibration Gas Se- quencer. The IFT provides a user-friendly, menu-driven operator interface with context- sensitive, on-line help. The IFT may also be used without an HPS.

The IFT is based on a modular design. There is a maximum total of four PC boards within the IFT. Every IFT contains a microprocessor board, a power supply board, and an intercon- nect board. In addition to these boards, deluxe version IFTs also contain a General User Inter- face/LED display board.

IFTs with no displays are known as "blind" units. Blind IFTs also lack a General User Interface (GUI) and must be controlled with an external HART communications device.

a.Microprocessor Board

The microprocessor board contains, EEPROM, RAM, and a timer. The micro- processor board also controls the probe heater. The IFT can be used in conjunction with or without an optional HPS 3000

Heater Power Supply providing power to the

heater depending upon the user'sE application.

b.Interconnect Board

The interconnect board is used for all com- munications from the IFT to the other com- ponents within the system. These other components may include an optional HPS 3000 Heater Power Supply, optional MPS Multiprobe Calibration Gas Sequencer, World Class 3000 Probe (non-HPS equipped system), analog output, and relay outputs.

c.Power Supply Board

The power supply board is user configur- able for five different line voltages to include 100, 120, 220, and 240 Vac. In addition, the output voltage for a probe heater is also configurable if used in a non-HPS equipped system.

d.GUI/LED Display Board (Optional)

The GUI/LED display board, which is part of the GUI assembly, has a 4-line by 20- character liquid crystal display and eight membrane keys. The board also contains an LED display which indicates the current

O2 value. The LED display has indicator LEDs for calibration gas high (TGH), cali- bration gas low (TGL) and calibrating (CAL).
