MODEL 1054B DO SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
1.1 GENERAL DESCRIPTION. The Model 1054B DO
Microprocessor Analyzer is designed to continuously measure and
control dissolved oxygen in industrial and municipal processes.
Housed in a NEMA 4X (IP65) weatherproof corrosion-resistant, flame
retardant enclosure, the Model 1054B is suitable for panel, pipe, or
wall mounting. All functions are accessed through the front panel
membrane keyboard which features tactile feedback.
The 1054B transmits a user selected isolated current output continuously expandable over the measurement range in either direct or
reverse action. The output can be displayed in milliamps or percent
of full scale. Output dampening is user selectable.
Dual programmable 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.
Time delay ignores temporary upsets and prevents relay chatter. An
interval timer with relay is also provided.
The 1054B DO analyzer, which is intended for use with a membrane-covered amperometric sensor, automatically compensates for
changes in membrane permeability with temperature. Temperature
can be displayed in either °C or °F.
Calibrating the analyzer is as simple as exposing the sensor to air
and keying in the barometric pressure. If removing the sensor from
the process is impractical, the analyzer can also be calibrated
against a laboratory measurement made on a grab sample.
Solubility correction factors for liquids containing high concentrations
of electrolytes can be programmed into the analyzer. The microprocessor automatically calculates ppm dissolved oxygen or % saturation.
The 1054B DO Microprocessor Analyzer comes with either LCD or
LED display. The display indicates dissolved oxygen in ppm or %
saturation as well as temperature, alarm status, hold output, and
fault conditions.

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,
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
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. Assure that the continuity wire is connected
to the rear cover and the interface board’s closest
mounting screws. Replace the door and four front
panel screws.
2.3.2 Wall Mounting Plate with Junction Box
(P/N 23054-01). Refer to Figures 2-3 and 2-4.
1. Prepare the analyzer as described in Section 2.3.
2. Mount the junction box and bracket to the analyzer with the hardware provided. All wiring can be
brought to the terminal strip prior to mounting the
analyzer.
3. Place the metal stiffener on the inside of the analyzer and mount the two 1/2-inch conduit fittings
using two each weather seals as shown. Mount
NEMA 4X conduit plug (included) into center conduit hole.
4. Mount the analyzer to the junction box using the
1/2-inch conduit fittings.
5. Complete wiring from the analyzer to the junction
box (Refer to Figure 2-4).
NOTE
Run sensor wiring out of the left opening
(From front view) to J-Box. All others out
right opening to J-Box.
2.3.3 Pipe Mounting (P/N 23053-00). The 2-inch 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 2-5.
2.3.4 Wall Mount Enclosure (option -20). See
Figure 2-7 for installation details.
2.4 ELECTRICAL WIRING.
All electrical connections are made to terminal strips
on the rear panel (interface board) of the instrument.
To access the interface board, remove the four (4)
screws securing the rear cover of the enclosure.
Gently pull away the rear cover, which is connected to
the back panel by a continuity wire. If the continuity
wire is disconnected for any reason, it must be reconnected to the nearest interface board mounting screw
before the rear enclosure cover is replaced.
The three openings in the bottom rear of the Model
1054B analyzer housing accommodate 1/2-inch conduit fittings. Looking at the analyzer from the front, the
conduit opening on the left is for sensor wiring, the
center opening is for signal output, and the opening
on the right is for timer, alarm, and AC connections.
Always run sensor wiring in a separate conduit from
power wiring.
NOTE
For best EMI/RFI protection, shield the
output cable and enclose it in an earthgrounded, rigid metal conduit. Connect
the outer cable shield to the earth
ground terminal on TB-A when using the
wall mounting junction box (Fig. 2-4) or
to terminal 8 on TB3 when wiring directly to the instrument (Fig. 2-6).
The sensor cable should also be shielded. When wiring directly to the instrument, connect the outer shield of the
sensor cable to the earth ground of the
instrument on terminal 8 of TB2. If the
outer shield of the sensor cable is braid,
an appropriate metal cable gland fitting
may be used to connect the braid to
earth ground by way of the instrument
case. When wiring to the wall mounting
junction box, connect the outer shield of
the sensor cable to the earth ground terminal on TB-A.
