SECTION 1.0
SPECIFICATIONS
1.1 FEATURES AND APPLICATIONS
The Model 54eA Analyzer/Controller with the appropriate sensor monitors and controls dissolved oxygen (ppm and ppb level), free chlorine, total
chlorine, and ozone in a variety of process liquids.
The analyzer is compatible with Rosemount
Analytical series 499A amperometric sensors for
oxygen, chlorine, and ozone; and with Hx438 and
Gx448 steam sterilizable oxygen sensors.
The amperometric sensors used with the Modeal
54eA produce a current directly proportional to the
concentration of the substance being determined.
Sensor currents are in the microampere to nanoampere range.
For oxygen measurements, an on-board pressure
sensor allows truly automatic air calibration. Simply
expose the sensor to water-saturated air. Wait until
readings are stable and press a button. The analyzer measures temperature and barometric pressure
and automatically completes the calibration.
For free chlorine measurements, both automatic and
manual pH correction are available. pH correction is
necessary because amperometric chlorine sensors
respond only to hypochlorous acid. To measure free
chlorine (hypochlorous acid plus hypochlorite ion)
most competing analyzers require an acidified sample. Acid lowers the pH and converts hypochlorite
ion to hypochlorous acid. The 54eA analyzer eliminates the need for messy and expensive reagents
by using the sample pH to correct the chlorine sensor signal. If the pH is relatively constant, a fixed pH
correction can be used. If the pH is greater than 7
and fluctuates more than about 0.2 units, continuous
measurement of pH and automatic pH correction is
necessary. Corrections are valid to pH 9.5.
The 54eA analyzer fully compensates oxygen,
ozone, free chlorine, and total chlorine readings for
changes in membrane permeability caused by temperature changes.
For pH measurements — pH is available with free
chlorine only — the 54eA features automatic buffer
recognition with stabilization check. Buffer pH and
temperature data for commonly used buffers are
stored in the analyzer. Glass impedance diagnostics
warn the user of an aging or failed pH sensor.
The analyzer has a rugged, weatherproof, corrosionresistant enclosure (NEMA 4X and IP65) of epoxypainted aluminum. It is suitable for panel, pipe, or wall
mounting. A hinged front cover provides convenient
access to wiring. Programming and calibration are
through the front membrane keypad, which has tactile feedback. The large back-lit dot-matrix display
shows the main measurement (oxygen, chlorine, or
ozone) in large numerals. The temperature and output current are shown in smaller numerals on the
second line. Two user-selectable variables can be
displayed on the third line. The pH measurement, if
used, appears on the third line.
Two independent, galvanically isolated outputs provide
4-20 mA or 0-20 mA signals for oxygen, chlorine,
ozone, pH, or temperature. Output 1 includes a HART
digital signal superimposed on the analog signal. The
controller option allows PID control on any measurement.
The Model 54eA has three programmable alarm
relays. Alarms can be assigned to the amperometric
measurement, pH, or temperature. Alarms have programmable high or low activation, independent setpoints, adjustable deadband, and time delay. Any
relay can be configured as a timer to control a spray
cleaner for the dissolved oxygen sensor. An overfeed timer feature is also available. The controller
option allows each alarm to be configured for time
proportional control (TPC). A fourth relay is a dedicated fault alarm.
The Model 54eA analyzer is a member of the
Rosemount SMART FAMILY®of instruments. The
analyzer communicates with the Model 275 HART
®
communicator or any other host, including AMS, that
supports the 275 HART communication protocol.

Will cause severe injury or death.
Alarm contacts are dry (i.e., not powered) and are normally open. Refer to Section 1.0 for relay specifications.
For best EMI/RFI protection, shield the output cable and enclose it in an earth-grounded, rigid, metal conduit.
Connect the outer shield of the output cable to the earth ground connection on TB2 (see Figure 3-1).
Keep sensor and output signal wiring separate from power wiring. Do no run sensor and power cables in the same
conduit or close together in a cable tray.
AC wiring must be 14 gauge or greater. Be sure to connect earth ground from the power cable to the nearby
ground lug. A good earth ground is necessary for proper operation of the controller. 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.
WARNING: RISK OF ELECTRICAL SHOCK
AC connections and grounding must comply with UL 508 or local electrical code. DO NOT apply
power to the analyzer until all electrical connections are verified and secure.
NOTE
The Model 54eA analyzer leaves the factory configured for use with the Model 499ADO sensor
(ppm dissolved oxygen). If a 499ADO sensor is NOT being used, turn to Section 5.5 and configure the transmitter for the desired measurement (ppb oxygen, oxygen measured using a
steam-sterilizable sensor, free chlorine, total chlorine, monochloramine, or ozone) before wiring
the sensor to the analyzer. Operating the analyzer and sensor for longer than five minutes while
the analyzer is improperly configured will greatly increase the stabilization time for the sensor.
Be sure to turn off power to the analyzer before wiring the sensor.

3.3.1 General
The wiring label, which is shown in Figure 3-2,
is a general purpose label. It has wiring information concerning other sensors, for example,
contacting and inductive conductivity sensors,
that can be used with the 54e instrument platform. For amperometric measurements, only
TB3 and TB5 are used. Wire the amperometric
sensor to TB3. Wire the pH sensor, if one is
being used, to TB5.
3.3.2 Wiring Model 499A oxygen, chlorine,
and ozone sensors
All 499A amperometric sensors (499ATrDO,
499ADO, 499ACL-01, 499ACL-02, 499ACL-03,
and 499AOZ) have identical wiring.
Use the pigtail wire and wire nuts provided with
the amperometric sensor when more than one
wire must be attached to a single terminal.

MODEL 54eA SECTION 3.0
WIRING
3.3.3 Wiring 499ACL-01 (free chlorine) sensors and pH sensors for automatic pH correction.
If free chlorine is being measured and the pH of the liquid varies more than 0.2 pH unit, a continuous correction
for pH must be applied to the chlorine reading. Therefore, a pH sensor must also be wired to the 54eA controller.
This section gives wiring diagrams for the pH sensors typically used.
When using the 499ACL-01 sensor (free chlorine) with a pH sensor, use the RTD in the pH sensor for measuring temperature. DO NOT use the RTD in the free chlorine sensor.
The pH sensor RTD is needed for temperature measurement during buffer calibration. During normal operation,
the RTD in the pH sensor also provides the temperature measurement required for the free chlorine membrane
permeability correction.
NOTE
When wiring a pH and amperometric sensor to the controller, connect the anode and reference
terminals (TB3-1 and TB5-1) with the 10MΩΩjumper (PN 23980-00) provided with the analyzer.
Refer to the table to select the appropriate wiring diagram. Most of the wiring diagrams require that two or more
shield wires be attached to a single terminal. Use the pigtail wire and wire nuts packed with the chlorine sensor to
make the connection.
Insulate and tape back unused wires.

DISPLAY AND OPERATION
4.1 GENERAL DESCRIPTION
The 54eA analyzer/controller is a normally a single
input, dual output instrument. It does, however, accept
a second input for pH when the main measurement is
free chlorine. Figure 4-1 shows how the instrument
inputs and outputs can be configured for free chlorine.
In addition to PID control, the 54eA controller can be
used for time proportional control (TPC). TPC control
uses the alarm relays.
4.2 DISPLAY
Figure 4-2 shows the main display.
4.3 KEY FUNCTIONS AND CONTROLS
The keys labeled F1, F2, F3, and F4 are multi-function.

4.4 ALARM STATUS
Green LEDs (labeled 1, 2, and 3) indicate when alarm
relays 1, 2, and 3 are energized. The fourth relay indicates a fault condition. When a fault occurs, the red
LED (labeled FAIL) lights up, a descriptive error message appears, and the outputs and alarm relays act as
described in Section 5.6 and Section 5.7 under fault
value.
The red LED also indicates when the interval timer routine is activated and when the time limit has been
reached on a feed limit timer. For more information on
these subjects, see Section 5.7.
FIGURE 4-1. Configuration of Inputs and Outputs
for Free Chlorine
The main sensor is always the chlorine sensor and the secondary sensor is always the pH sensor. Outputs can be
assigned to free chlorine, to pH, or to temperature. The
outputs can be configured as either linear (4-20 mA) or PID
outputs.
FIGURE 4-2. Main Display Screen
The amperometric measurement (oxygen, ozone, free
chlorine, or total chlorine) is always displayed continuously
in large numerals. The temperature and output current are
always displayed on the second line of the main display.
The third line can be configured by the user. In the example, the third line shows the pH reading and the amperometric sensor current in nA.
