This document provides basic instruction for the installation Section Page and commissioning of the ABB 2600T. This transmitter is connected to a process by means of impulse lines and can 1. INTRODUCTION ............3 measure Pressure or Absolute pressure. The measurement is transmitted to a control system by means of a 4-20 mA signal 2.
PHASE 1 - PRELIMINARY CHECKS that all the parameters listed on this label (or on the certificates 2. PRELIMINARY CHECKS enclosed with the transmitter) are in accordance with the Before mounting the transmitter, check the compatibility with requirements of the area where the transmitter is going to be the following measurement and safety requirements: installed.
(the manual is available at www.abb.com inserting - 21MPa, 210bar, 3045psi for sensor codes P, Q, S in the “search” tool the keyword “IM/26X”) or from local ABB representatives. For EEx ia and intrinsically safe (FM, CSA and SAA) approvals,...
Electromagnetic compatibility (EMC) process flanges and sensor diaphragm. Complies with EN 50081–1 for emission and EN 50082–2 for A fluid / material compatibility table is available at www.abb.com immunity requirements and test; (inserting in the “search” tool the keyword “TB/COR”) or from Radiated electromagnetic immunity level: 30V/m (according to local ABB representatives.
PHASE 2 - TRANSMITTER INSTALLATION 3. TRANSMITTER INSTALLATION The following examples are standard mounting locations for instrumentation suitable for these main types of applications: TRANSMITTER LOCATION Level measurement with open tanks 1. Mount the transmitter at the same height or below of the lowest level to be measured.

PHASE 2 - TRANSMITTER INSTALLATION Pressure or absolute pressure measurement of a liquid in a pipe 1. Place the tap at the side of the line. Dirty fluids 2. Mount the transmitter beside or below the tap for clean fluids, above the tap for dirty fluids. 3.
PHASE 2 - TRANSMITTER INSTALLATION TRANSMITTER MOUNTING Orient the process flanges to enable process connections to be made. It is important to mount the transmitter and to lay the process piping so that gas bubbles, when measuring liquids, or condensate when measuring gases, can flow back into the process.
PHASE 2 - TRANSMITTER INSTALLATION ROTATION Housing Rotation To improve field access to wiring or the readability of the optional LCD meter it is possible to rotate the Housing and the Meters or the Integral display. Housing Rotation Unlock the housing rotation set screw by turning it 1 turn (use the 3 mm Allen key supplied with the instrument) Turn the housing clock wise or counterclockwise up to 180°...
PHASE 3 - TRANSMITTER WIRING 5. Run the cable through the cable gland and the open port. TRANSMITTER WIRING 6. Connect the positive lead to the + terminal, and the negative lead to the – terminal. PROTECTIVE GROUNDING All transmitters are supplied with an external ground connection ✶...
PHASE 4 - TRANSMITTER OPERATION 5. TRANSMITTER OPERATION Use the following step to adjust the transmitter zero. PRESSURE MEASUREMENT 1. Slowly open the gate valve to admit process fluid to primary of side H. 2. Vent all entrapped air (liquid service) or drain any condensate (gas service) from primary using the vent/drain valve. 3.
PHASE 4 - TRANSMITTER OPERATION LEVEL MEASUREMENT 1. Vent all entrapped air from primary using vent/drain valves on the transmitter, then close them. Max. Level 2. Make sure to have the level in the tank at the required Max. Level reference (minimum) level Note - In case it is not possible to empty the tank, it is possible to follow the Zero Raise/Lower adjustment...
DISMANTLING AND REASSEMBLY Reassembly WARNING - Process fluids and/or pressure retained in the transmitter primary unit can cause severe injury and WARNING - Assembling flanges with incorrect death or damage to the equipment. It is the user fixing bolts and nuts and improper "O rings" can cause responsibility to make sure that no pressure is applied fracture or overstressing of bolts and release of pressurized before removing the instrument from service or when...
