DESCRIPTION AND SPECIFICATIONS

1.1 FEATURES AND APPLICATIONS

The Model 1054B Microprocessor Analyzers, with the
appropriate sensors, are designed to continuously meas­ure and control pH, ORP, conductivity, resistivity, ratio,
percent concentration, dissolved oxygen, ozone or total
free chlorine in industrial and municipal processes.

The Model 1054B Dual Conductivity/Resistivity Analyzer
offers the flexibility of one model for measurement of two
cell inputs with two assignable outputs of conductivity,
resistivity and/or temperature. The analyzer is housed in
a NEMA 4X (IP65) weatherproof, corrosion-resistant,
flame retardant enclosure suitable for panel, pipe or wall
mounting. All functions are accessed through the front
panel membrane keyboard which features tactile feed­back. The display indicates the process variable values
in engineering units as well as temperature, alarm sta­tus, hold output and fault conditions.

The 1054B DC can transmit two independent, isolated
current outputs which are continuously expandable over
the measurement range. Output dampening of 0-255
seconds is user selectable.

The output and relay default settings are user selectable
for hold or fault mode operation. The hold output function
allows manual control during routine sensor maintenance.

Continuous self diagnostics alert the operator to faults
due to analyzer electronics, integral RTD failures, open
wiring and process variable range problems. In the event
of a fault condition or hold mode diagnosed by the ana­lyzer, the output will be set to a preset or last process
value and the relays will be set to their default settings.

Three alarms are a standard feature on the Model
1054B DC and are programmable for either high or low
operation. Alarm 2 may be programmed as a fault or
process variable alarm. Alarm 3 may be configured as
a temperature alarm only. All alarms feature independ­ent setpoints, adjustable hysteresis and time delay
action. The time delay is convenient when an alarm is
used for corrective action, such as shutting down a
demineralizer for regeneration. Time delay will ignore a
temporary breakthrough and prevent shutting down a
de-mineralizer unit prematurely.

Automatic temperature compensation is standard. The
process temperature is accurately measured by an inte­gral RTD in the sensor assembly, either a PT100 or
PT1000, which is automatically recognized by the ana­lyzer. The temperature(s) can be displayed in either °C
or °F. For greater accuracy, the temperature indication
may be standardized to the process temperature.

Calibration is easily accomplished by entering the cell
calibration constant (shown in the sensor tag) via the
analyzer keypad. Standardization can also be made
with the cell in process of known conductivity (resistivi­ty).

Analyzer settings may be protected against accidental
or unauthorized changes by a user selectable security
code.

• TWO CELL INPUTS OR TEMPERATURE ASSIGNABLE TO TWO ISOLATED
OUTPUTS.

• ACCURATE TEMPERATURE COMPENSATED AND RAW READINGS for high
purity water.

• UP TO 200 FEET (61m) SENSOR CABLE LENGTH (to 500 ft with extra shielding).

• THREE ASSIGNABLE RELAYS for process variable, temperature, or diagnostics.

• DISPLAY CAN AUTO CYCLE CELL 1 AND 2.

• NEMA 4X (IP65) ENCLOSURE.

• SECURITY CODE CAPABILITY.

The Model 1054B DC Dual Cell Analyzer measures conductivity and/or resistivity in conventional and ultrapure
water applications. This time tested technology has been applied successfully to demineralizer, reverse osmosis,
and distillation applications for decades.In this single analyzer, true temperature compensation for monitoring
water containing trace mineral contaminants is software selectable among the following:

1. Compensation for pure water contaminated with trace amounts of sodium chloride (standard).

2. Cation compensation for power plant applications containing ammonia or amines. Cation compensation may
also be used in semiconductor etch rinse applications where the rinse water contains traces of acids.

3. Uncompensated conductivity for applications such as required by United States Pharmacopeia 23 (USP 23)
specifications. The analyzer can output temperature separately for this application. NIST traceable calibration
certificates are available (consult factory).

The analyzer may be used with sensors having cable length of up to 200 ft (61 m). The cable length may be up to
500 ft (152m) with extra shielding (contact factory).

INSTALLATION

SECTION 2.0

INSTALLATION

2.1 GENERAL. This analyzer's enclosure is suitable

for outdoor use. However, it should be located in an
area where temperature extremes and vibrations are
minimized or absent. Installation must be performed by
a trained technician.

2.2 UNPACKING AND INSPECTION. Inspect the
analyzer for shipping damage. If damaged, notify the
carrier immediately. Confirm that all items shown on
the packing list are present. Notify Rosemount
Analytical if items are missing.

2.3 MECHANICAL INSTALLATION. Select an instal­lation site that is at least one foot from any high volt­age conduit, has easy access for operating personnel,
and is not in direct sunlight. Mount the analyzer as fol­lows:

1. Remove the four screws that secure the rear
cover of the enclosure.

2. Remove the four screws holding the front panel
assembly of the enclosure and carefully pull the
front panel and connected printed circuit boards
straight out.

3. Follow the procedure for the appropriate mounting
configuration: Section 2.3.1 for panel mounting
and Section 2.3.2 for pipe mounting.

2.3.1 Panel Mounting (Standard). The Model 1054B

is designed to fit into a DIN standard 137.9 mm X

137.9 mm (5.43 inch X 5.43 inch) panel cutout

(Refer to Figures 2-1 and 2-2).

1. Prepare the analyzer as described in Section 2.3.

2. Install the mounting latches as described in Figure
2-2 (latches are shown oversize for clarity). If the
latches are not installed exactly as shown, they
will not work correctly. The screws provided are
self-tapping. Tap the screw the full depth of the
mounting latch (refer to side view) leaving a gap
greater than the thickness of the cutout panel.

3. Align the latches as shown and insert the analyz­er enclosure through the front of the panel cutout.
Tighten the screws for a firm fit. To avoid damag­ing the mounting latches, do not use excessive
force.

4. Replace the front panel assembly. Circuit boards
must align with the slots on the inside of the enclo­sure. Replace the door and four front panel
screws.

2.3.2 Pipe Mounting (PN 23053-00). The 2 in. pipe

mounting bracket includes a metal plate with a cutout
for the analyzer (Refer to Section 2.3 for mounting the
analyzer into the plate). Mounting details are shown in
Figure 2-3.

2.4 ELECTRICAL WIRING. The Model 1054B has

three conduit openings in the bottom rear of the ana­lyzer housing which will accommodate 1/2 inch con­duit fittings. From the front view, the conduit opening
on the left is for sensor wiring; the center is for signal
output and the opening on the right is for alarm, and
AC connections. Sensor wiring should always be run
in a separate conduit from power wiring. AC power
wiring should be 14 gauge or greater.

NOTE

For best EMI/RFI protection the output
cable should be shielded and enclosed
in an earth grounded rigid metal conduit.
When wiring directly to the instrument
connect the output cable’s outer shield
to the transmitter’s earth ground via ter­minal 8 on TB3 (Fig. 2-4). The sensor
cable should also be shielded. When
wiring directly to the instrument connect
the sensor cable’s outer shield to the
transmitter’s earth ground via terminal 8
on TB-2 (Fig 2-4.) If the sensor cable's
outer shield is braided an appropriate
metal cable gland fitting may be used to
connect to braid to earth ground via the
instrument case.

The user must provide a means to dis­connect the main power supply in the
form of circuit breaker or switch. The cir­cuit breaker or the switch must be locat­ed in close proximity to the instrument
and identified as the disconnecting
device for the instrument

6

MODEL 1054B DC SECTION 2.0

INSTALLATION

2.4.1 Power Input Wiring. The Model 1054B can be

configured for either 115 VAC or 230 VAC power.
Connect AC power to TB1-8 and -9 (115 VAC) or TB1-

7 and -8 (230 VAC) ground to the ground terminal at
TB3-8 (refer to Figure 2-4).

CAUTION

The sensitivity and stability of the analyzer
will be impaired if the input wiring is not
grounded. DO NOT apply power to the
analyzer until all electrical connections are
verified and secure. The following precau­tions are a guide using UL 508 as a safe­guard for personnel and property.

1. AC connections and grounding must be in compli­ance with UL 508 and/or local electrical codes.

2. The metal stiffener is required to provide support
and proper electrical continuity between conduit
fittings.

3. This type 4/4X enclosure requires a conduit hub
or equivalent that provides watertight connect,
REF UL 508-26.10.

4. Watertight fittings/hubs that comply with the
requirements of UL 514B are to be used.

5. Conduit hubs are to be connected to the conduit
before the hub is connected to the enclosure, REF
UL 508-26.10.

6. If the metal support plate is not used, plastic fit­tings must be used to prevent structural damage
to the enclosure. Also, appropriate grounding lug
and awg conductor must be used with the plastic
fittings.

2.4.2 Output Wiring. The signal output and alarm

connections are made to terminals 1 – 6 of TB1 and
TB3 1 – 4. (Refer to Figure 2-4).

2.4.3 Sensor Wiring. See Figure 2-5.

2.5 SENSOR INSTALLATION.

The Model 1054B DC is designed to work with 400
Series, 140 Series, and 150/160 sensors. Refer to
Figure 2-4 and Figure 2-5 for sensor wiring. Wire col­ors are: BLACK is CELL-1/2 TB2-1/5: WHITE is
GROUND TB2-2/6: RED is RTD-1/2 TB2-3/7.

2.5.1 Cell Location. A mounting location should be
chosen to meet the following considerations:

1. Avoid dead ends or pipe stubs or any location
where circulation might be poor.

2. If velocity is very low, mount the cell so that the
stream is directed against the end of the elec­trodes and the water will flow between the elec­trodes.

3. Be sure that the pipe is full of water and that the
cell is completely immersed up to the pipe
threads.

4. Cell mounting vertically downward is not recom­mended due to possible air entrapment.

2.5.2 Screw-in Cell Installation. The conductivity cells

should be screwed gently into a female pipe fitting
using a parallel jaw wrench. Threads of stainless steel
should be coated with a suitable pipe compound which
will act to seal the treads, and prevent the need for
overtightening. Teflon thread tape is recommended for
this purpose. After the cell is installed, the cell cable
should be supported in such a way as to reduce strain
and minimize the danger of the cable becoming
snagged and pulled from the cell.

2.5.3 Flow Through Cell Installation. The flow

through cells are provided with 1/4" Swagelok

TM

tube
fittings. These are suitable for direct insertion into 1/4"
O.D. sample lines. If connection to the plastic tubing
is desired, the SwagelokTMfittings may be removed
and replaced with 1/4" FPT - hose barb fittings. Fitting
threads should be coated with a suitable pipe com­pound which will act to seal the treads, and prevent
the need for overtightening. Teflon thread tape is rec­ommended for this purpose. After the cell is installed,
the cell cable should be supported in such a way as to
reduce strain and minimize the danger of the cable
becoming snagged and pulled from the cell.
