CONDENSED OPERATING INSTRUCTIONS
This manual contains details for all operating aspects of the instrument. The following condensed instructions are provided to assist you in getting the instrument started up and operating as quickly as
possible. These condensed instructions only pertain to basic dissolved oxygen measurement op-
eration (in ppm). To use specific features of the instrument, refer to the appropriate sections in this
manual for instructions.
A. CONNECTING SENSOR(S)
The analyzer can always be used with one sensor connected to SENSOR A terminals. When the
analyzer is equipped with the optional two sensor input software, a second sensor can be connected
to SENSOR B terminals and used for monitoring.
1. After the analyzer is properly mounted (Part Two, Section 2), install the GLI membrane dissolved
oxygen sensor(s). Refer to the sensor instruction manual for details.
2. When using GLI mounting hardware, plug the sensor cable into the mating receptacle on the
junction box. Route the 6-conductor interconnect cable (GLI part number 1W1100) from the
junction box to the analyzer.
3. At the analyzer end of the interconnect cable, twist the two shield wires together. Then insulate
them with plastic tubing or tape to prevent inadvertent shorting, and connect the combined shield
to one of the 5 open holes on the grounding strip at the bottom of the analyzer case (Figure 2-3).
4. Connect the other interconnect cable wires to the analyzer SENSOR A terminals on TB1,
matching colors as indicated:
Sensor A
Interconnect Cable Connections
Wire Colors At Analyzer Terminals Wire Colors At Analyzer Terminals
Red #10 on TB1 Red #16 on TB1
Green #11 on TB1 Green #17 on TB1
Blue #12 on TB1 Blue #18 on TB1
White #13 on TB1 White #19 on TB1
Black #14 on TB1 Black #20 on TB1
Yellow #15 on TB1 Yellow #21 on TB1
Cable shields Grounding strip lug Cable shields Grounding strip lug
Optional Sensor B Input
Interconnect Cable Connections
5. At the junction box end of the interconnect cable, twist the two shield wires together. Then connect the combined shield to the junction box terminal corresponding to the white wire with black
stripe. Connect the other interconnect cable wires to terminals corresponding to their wire colors.
NOTE: When the analyzer is equipped with the optional sensor quick-disconnect receptacle(s),
simply plug the sensor cable(s) into them. This eliminates using the junction box supplied
with GLI sensor mounting hardware, and the need for interconnect cable.
B. CONFIGURING SENSOR TEMPERATURE ELEMENT(S)
The analyzer is supplied factory-set for automatic temperature compensation using the NTC 30K
ohm thermistor element built into GLI membrane dissolved oxygen sensors. For fixed manual temperature compensation, you must change the temperature element type to “MANUAL” (see Part
Three, Section 4.3, subheading “Selecting Temperature Element Type”) and enter a temperature.
NOTE: When the analyzer is equipped with the optional two sensor input software and only one
sensor is being used, the unused sensor input must be set for “MANUAL” compensation to
prevent a “WARNING: CHECK STATUS” message from appearing.

CONDENSED OPERATING INSTRUCTIONS
C. CONNECTING LINE POWER
Important: Follow the instructions in Part Two, Section 3.5 to connect line power to the analyzer.
D. ADJUSTING DISPLAY CONTRAST
Ambient lighting conditions may make it necessary to adjust display contrast to improve visibility.
With the MEASURE screen displayed, press and hold the ENTER key and simultaneously press the
ññ or òò key until attaining the desired contrast.
E. CALIBRATING THE ANALYZER
The analyzer must be calibrated for dissolved oxygen concentration so that measured values will
correspond to actual process values. Use one of the three different methods available.
Calibration Tip! It is highly recommended to use the “AIR CAL” method with one of the special
calibration bags provided with the GLI membrane D.O. sensor because this:
• Ensures high calibration accuracy by providing a stable atmosphere at the sensor membrane.
• Provides more convenience than using a portable meter to determine the known D.O. value
(even when an optional GLI washer head assembly is attached to sensor for self-cleaning).
• Provides high repeatability because the sensor is in a controlled environment.
CAUTION:
DURING INTIAL STARTUP AND BEFORE CALIBRATION, ALWAYS CONDITION THE
MEMBRANE D.O. SENSOR BY OPERATING IT IN WATER FOR AT LEAST 12 HOURS TO
POLARIZE THE ELECTRODES. FAILURE TO PROPERLY CONDITION THE SENSOR WILL
RESULT IN SIGNIFICANT MEASUREMENT ERROR.
NOTE: When using a second sensor, calibrate SENSOR B in the same way using its respective
menu screens.
Since GLI highly recommends the “AIR CAL” method for calibration, it is described below. (To use
one of the other methods, refer to Part Three, Section 5 for instructions.) With the “AIR CAL”
method, the analyzer automatically calibrates itself using the atmospheric pressure or altitude value
you previously entered, and the measured temperature in the calibration bag. (For theoretical D.O.
calibration values based on measured temperature, refer to Table D. The actual calibration value
may be slightly different because of the variation for the entered atmospheric pressure or altitude.)
1. Enter the known atmospheric pressure or altitude in your geographic area.

SECTION 1
GENERAL INFORMATION
1.1 Capability Highlights
Sensor Input
The analyzer always has one sensor input but may be
equipped with the optional two sensor input software. This
option provides two independent sensor inputs for monitoring two measurement points. Each input accepts a GLI
membrane dissolved oxygen sensor that has a built-in NTC
30K ohm thermistor.
MEASURE Screen
(normal display mode)
Passcode-protected
Access
The measured dissolved oxygen is shown on the
MEASURE screen (normal display mode). When the analyzer is equipped with the optional two sensor input
software, pressing the ðð or ïï key while viewing the
MEASURE screen sequentially shows these measurements:
• Measured Sensor A dissolved oxygen.
• Measured Sensor B dissolved oxygen.
• Measured Sensor A and B dissolved oxygen and
temperatures (all together on same screen).
The bottom auxiliary display line, shown in reverse video,
can be changed by pressing the òò and ññ keys to show
these other measurements:
• Measured Sensor A temperature (°C or °F).
• Measured Sensor B temperature (°C or °F).
• Analog Output #1 value (mA).
• Analog Output #2 value (mA).
For security, you can enable a passcode feature to restrict
access to configuration and calibration settings to authorized personnel only. See Part Three, Section 4.7 for details.
Calibration Guidelines
Rev. 0-599 Model D53 D.O. Analyzer (universal-mount 1/2 DIN)
Three methods are provided for D.O. calibration. It is highly
recommended to use the “AIR CAL” method for convenience and accuracy. For calibration details on all methods,
refer to Part Three, Sections 5.1 and 5.2. The analyzer also
provides two methods for calibrating temperature (Section
5.3). This feature, however, is typically not needed since the
analyzer is factory-calibrated for highly accurate tempera-

PART ONE - INTRODUCTION SECTION 1 - GENERAL INFORMATION
The analyzer provides two
isolated analog outputs (#1
and #2). Each output can be
set to be 0-20 mA or 4-20
mA, and assigned to represent the measured dissolved
oxygen or temperature.
The analyzer has four electromechanical relays, all with
SPDT contacts. Each relay can be set to function as a control relay, dual-alarm relay, status relay, or a timer relay,
and assigned to be driven by the measured dissolved oxygen or temperature.

Refer to Part Three, Section 4.6 for relay setup details.
Parameter values can be
entered to define the endpoints at which the minimum
and maximum analog output
values are desired.
During calibration, both analog outputs can be selected
to:
• Hold their present values
(HOLD OUTPUTS)
• Transfer to preset values
to operate control elements by an amount
corresponding to those
values (XFER
OUTPUTS)
• Remain active to respond
to the measured value
(ACTIVE OUTPUTS).
For analog output transfer
setup details, see Part Three,
Section 4.5 under the subheading “Setting Transfer
Value.”

1.2 Modular Construction
NOTE: When a relay is set to function as a status relay, it is
no longer configurable. Instead, it becomes a dedicated system diagnostic-only alarm relay that
automatically energizes when the “WARNING
CHECK STATUS” message flashes on the
MEASURE screen. This occurs when the analyzer
detects a “fail” diagnostic condition. See Part Three,
Section 6.1 for more details.
Except for status relays, during calibration the relay on/off
states are affected in the same way as the analog outputs
by the “(HOLD/XFER/ACTIVE OUTPUTS)” screen selection. These relays are also held at their present on/off
states, transferred to desired preset on/off states, or remain
active to respond to measured values. For relay transfer
setup details, see Part Three, Section 4.6, under the subheading “Selecting Transfer Mode.”
The modular construction of the analyzer simplifies field
servicing and provides electrical safety. The front door/
keypad assembly uses voltages no greater than 24 VDC,
and is completely safe to handle.

Configuration Values
1.4 Analyzer
Serial Number
Opening the analyzer door accesses terminals inside the
enclosure for electrical connections. Line power must be
connected to specifically designated terminals on TB3.
WARNING:
REMOVE LINE POWER BEFORE NEARING THIS AREA
TO AVOID ELECTRICAL SHOCK.
All user-entered configuration values are retained indefinitely, even if power is lost or turned off. The non-volatile
analyzer memory does not require battery backup.
A label with the analyzer model number, serial number,

3.2 Analog Outputs
☞
☞
Two isolated analog outputs (#1 and #2) are provided. Each
output can be set to be 0-20 mA or 4-20 mA. Also, each
output can be assigned to represent the measured dissolved oxygen or temperature.
NOTE: When the analyzer is equipped with the optional
two sensor input software, an analog output can
also represent the SENSOR B measured dissolved oxygen or temperature.
For details on configuring the outputs, refer to Part Three,
Section 4.5.
Wiring Tip! Use high quality, shielded instrumentation
cable for connecting the analog outputs. To protect the
output signal from EMI/RFI, connect cable shields to one
of the 5 open holes on the grounding strip at the bottom
of the case (Figure 2-3).
Each 0/4-20 mA output can drive a load of up to 600 ohms.
☞
• For Output #1: Connect the load to Terminals 1 and 2 on
TB1, matching polarity as indicated.
• For Output #2: Connect the load to Terminals 3 and 4 on
TB1, matching polarity as indicated.
NOTE: When using the HART communication option, a
digital signal is encoded onto the 4-20 mA analog
Output #1 signal. In a HART point-to-point wiring
configuration, Output #1 remains available for normal use. However, in a HART multi-drop wiring
configuration, Output #1 becomes dedicated to that
function and cannot be used. See Part Three, Section 8 for more HART communication information.

3.3 Relay Outputs
The analyzer is equipped with four electromechanical relays. For relay setup details, see Part Three, Section 4.6.
CAUTION:
DO NOT EXCEED THE CONTACT RATING FOR
EACH RELAY (5A 115/230 VAC). WHEN SWITCHING
LARGER CURRENTS, USE AN AUXILIARY RELAY
SWITCHED BY THE ANALYZER RELAY TO EXTEND
ANALYZER RELAY LIFE. WHEN USING RELAY
OUTPUTS, MAKE SURE THAT LINE POWER WIRING
CAN ADEQUATELY CONDUCT THE CURRENT
DRAW OF THE SWITCHED LOAD(S).
Four sets of SPDT relay outputs (Relays A, B, C, and D) are
provided at Terminals 1 through 12 on TB2. The relay out-
puts are not powered. The line power used to power the
analyzer may also be used to power control/alarm devices
or GLI air blast sensor cleaning systems with these relay
contacts. Refer to Figure 2-5 for a general wiring arrangement. Always check control wiring to insure that line power
will not be shorted by the relay switching action, and that
wiring conforms to local codes.
WARNING:
MAKE SURE THAT LINE POWER IS NOT PRESENT
WHILE CONNECTING WIRES TO TB2 RELAY
TERMINALS.

3.4 Closed Contact
TTL Input
3.5 Line Power
☞
The analyzer closed contact TTL input feature enables you
to conveniently:
• Hold analog outputs at their present values.
• Hold control and alarm relays in their present on/off
states.
• Suspend countdown, temporarily, of active timer relays.
To initiate these actions, simply locally or remotely jumper
TTL Terminals 8 and 9 on TB1.
NOTE: During a calibration, the selected output state
(“HOLD,” “XFER” or “ACTIVE”) overrides the actions of the TTL input feature.
Refer to Figures 2-6, 2-7 or 2-8 on the next page and connect line power to TB3 terminals using the standard threewire connection arrangement. Use wiring practices which
conform to local codes (example: National Electric Code
Handbook in the U.S.A.).
☞
☞
WARNING:
REMOVE LINE POWER WHILE CONNECTING LINE
POWER WIRES TO THE TB3 TERMINALS. ALSO,
USE ONLY THE STANDARD THREE-WIRE CONNECTION ARRANGEMENT FOR SINGLE-PHASE LINE
POWER TO PREVENT AN UNSAFE CONDITION, AND
TO ENSURE PROPER ANALYZER OPERATION.
NOTE: In all cases, connect the line power cable ground
wire (usually green) to one of the 5 open holes on
the grounding strip at the bottom of the analyzer
case.
The “115” and “230” voltage circuits are protected with internal, board-mounted slow-blow fuses.
NOTE: For 230 volt split phase line power, be sure to con-
form to local codes with regard to fusing the 115
volt line connected to the “N” terminal.
