April 2020 Quick Start Guide

CAUTION

Reading errors

During operation, the debubbler is under pressure. A 0.040 in. (1
mm) orifice in the outlet provides the pressure. Back pressure helps
prevent outgassing, which can lead to bubbles accumulating on the
sensor face, resulting in erroneous readings.

Do not exceed 30 psig (308 kPa abs) inlet pressure.

The amount of pressure in the debubbler can be estimated from the
flow rate. See Table 1-2.

locations marked on the board.

2. Carefully slide the wired board fully into the enclosure slot and take
up the excess sensor cable through the cable gland.

3. Tighten the cable gland nut to secure the cable and ensure a sealed
enclosure.

2.1.3 Digital communication boards

2.1.4 Alarm relays

Emerson supplies four alarm relays with the switching power supply (85 to
264 Vac, 03 order code) and the 24 Vdc power supply (20 - 30 Vdc, 02 order
code). You can use all relays for process measurement(s) or temperature.
You can also configure any relay as a fault alarm instead of a process alarm.
In addition, you may configure any relay independently and program it to
activate pumps or control valves.

As process alarms, alarm logic (high or low activation or USP*) and
deadband are user-programmable. Customer-defined failsafe operation is
supported as a programmable menu function to allow all relays to be
energized or not energized as a default condition upon powering the
transmitter. You may program the USP* alarm to activate when the

16 Emerson.com/Rosemount

April 2020 Quick Start Guide

conductivity is within a user-selectable percentage of the limit. USP*
alarming is available only when a contacting conductivity measurement
board is installed.

2.2 Prepare conduit openings

The transmitter enclosure has six conduit openings. Four conduit openings
are fitted with conduit plugs.

Conduit openings accept ½-in. conduit fittings or PG 13.5 cable glands. To
keep the case watertight, block unused openings with NEMA® 4X or IP65
conduit plugs.

Note

Use watertight fittings and hubs that comply with the requirements of
UL514B. Connect the conduit hub to the conduit before attaching the fitting
to the transmitter (UL508-26 16).

2.3 Prepare sensor cable

The Rosemount T1056 is intended for use with all Rosemount sensors. Refer
to the sensor installation instructions for details on preparing sensor cables.

2.4 Power, output, and sensor connections

2.4.1 Power wiring

Emerson offers two power supplies for the Rosemount T1056

AC mains (115 or 230 V) leads and 24 Vdc leads are wired to the power
supply board which is mounted vertically on the left side of the main
enclosure cavity. Each lead location is marked clearly on the power supply
board. Wire the power leads to the power supply board using the lead
markings on the board.

Quick Start Guide 17

Quick Start Guide April 2020

Figure 2-1: 24 Vdc Power Supply (02 Ordering Code)

2.4.2 Current output wiring

Emerson ships all instruments with two 4-20 mA current outputs. Wiring
locations for the outputs are on the main board which is mounted on the
hinged door of the instrument.

Wire the output leads to the correct position on the main board using the
lead markings (+/positive, -/negative) on the board. Emerson provides male
mating connectors with each unit.

For best EMI/RFI protection use shielded output signal cable enclosed in an
earth-grounded metal conduit. Connect the shield to earth ground. AC
wiring should be 14 gauge or greater. Provide a switch or breaker to
disconnect the analyzer from the main power supply. Install the switch or
breaker near the analyzer and label it as the disconnecting device for the
analyzer.

Keep sensor and output signal wiring separate from power wiring. Do not
run sensor and power wiring in the same conduit or together in a cable tray.
