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 Conductivity Analyzers are 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. Measurement data may be read at any time.
However, settings may be protected against accidental
or unauthorized changes by a user selectable security
code. The display indicates the measured value in engineering units as well as temperature, alarm status, hold
output and fault conditions.
The 1054B transmits a user selected isolated current
output which is continuously expandable over the measurement range for either direct or reverse action and can
be displayed in milliamps or percent. Output dampening
of 0-255 sec. 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.
Dual alarms are a standard feature on the Model 1054B
and are programmable for either high or low operation.
Alarm 2 may be programmed as a fault alarm. Both
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 demineralizer unit prematurely. A dedicated interval timer with relay is also provided.
Automatic or manual temperature compensation is keyboard selectable. The process temperature is accurately
measured from an integral RTD in the sensor assembly
and is read on the display. For greater accuracy, the temperature indication may be standardized to the process
temperature. The temperature may be configured to read
in °C or °F.
Calibration is easily accomplished by simply immersing
the sensor in a known solution and entering the value.
With a two point calibration, the Model 1054B will automatically calculate the temperature slope of the solution.
Upon routine standardization a sensor cell factor value is
calculated, and a trend of this value can be used to track
sensor coating.
The Model 1054B Microprocessor Analyzer comes standard with an LCD display. An LED display is available as
an option.
• SELF DIAGNOSTICS with a user selectable fault alarm.
• KEYBOARD SECURITY is user selectable.
• NO BATTERY BACK-UP REQUIRED. Non-volatile EEPROM memory.
• DUAL ALARMS WITH PROGRAMMABLE LOGIC. A third relay is provided with timer functions.
• PROGRAMMABLE OUTPUT AND RELAY DEFAULTS for hold and fault modes.
• NEMA 4X (IP65) WEATHERPROOF CORROSION-RESISTANT ENCLOSURE.

DESCRIPTION AND SPECIFICATIONS
The Model 1054B Conductivity Analyzer measures over the range of 0-2 µS/cm to 0-1,000 mS/cm.
Temperature slope may be adjusted anywhere between 0 and 5% to provide greater accuracy in chemical concentration control. The temperature slope is factory set at 2% as a representative value, but each conductive
solution has its own set of temperature vs. concentration curves. The Model 1054B C will automatically calculate the temperature slope for any given solution, or permit manual adjustment of the temperature slope if
already known. On calibration the analyzer will also automatically correct for cell constant variations for better
measurement accuracy.

lation 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,
Section 2.3.2 for wall mounting, Section 2.3.3 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 in. x 5.43 in.) panel cutout (Refer to
Figure 2-1 and Figure 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

MODEL 1054B C SECTION 2.0
INSTALLATION
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 timer, 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 maximum 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.
When wiring to the wall mounting junction box connect the output cable’s outer
shield to the earth ground terminal on
TB-A.
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 of TB-2. 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. When wiring to
the wall mounting junction box connect
the sensor cable’s outer shield to the
earth ground terminal on TB-A.
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.
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 TB17 and -8 (230 VAC) ground to the ground terminal at
TB3-8 (refer to Figure 2-6).
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 through 6 of TB1
and TB3-1 and 2. (Refer to Figure 2-6).
