IMPORTANT SAFETY INFORMATION
This transmitter is compliant with safety standards as outlined in:
FMRC Class Numbers 3600, 3611, and 3810 (U.S.A.)
CSA C22.2 No. 142 and C22.2 No. 213 (Canada)
EN 61010-1 (European Community)
Please read and observe the following:
•
The transmitter (not intrinsically safe) must always be located in a safe (non-hazardous) area.
•
Since the transmitter is powered by only low DC voltage, it is completely safe to handle.
•
Wiring or repairs should only be performed by qualified personnel, and only when transmitter is unpowered.
•
Whenever it appears that transmitter safety is questionable, disable the transmitter to ensure against
any unintended operation. For example, an unsafe condition is likely when:
1) The transmitter appears visibly damaged.
2) The transmitter fails to operate properly or provide the intended measurements.
3) The transmitter has been stored for long periods at temperatures above 158°F (70°C).
•
Install this transmitter in accordance with relevant local codes and instructions contained in this oper-
ating manual. Also, note and comply with the transmitter’s technical specifications and ratings.
HELPFUL IDENTIFIERS
In addition to information on installation and operation, this instruction manual may contain

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.
tion.
These condensed instructions only pertain to basic conductivity measurement
To measure % concentration or TDS, or to use specific features of the instrument, refer to the
appropriate sections in this manual for instructions.
A. CONNECTING SENSOR/CONFIGURING TEMPERATURE ELEMENT TYPE
1. After properly mounting the transmitter (PART TWO, Section 2), connect the GLI electrodeless
conductivity sensor, matching wire colors to terminals as indicated:
Sensor Wire Colors Connect To TB2
White Terminal 1
Blue Terminal 2
Inner and Outer Shield Wires Terminal 3
Red Terminal 4
Yellow Terminal 5
No connection (not used) Terminal 6
Green Terminal 7
2. The transmitter is supplied factory-set for automatic temperature compensation using the Pt
1000 ohm temperature element built into GLI electrodeless conductivity sensors. For fixed
MANUAL temperature compensation, you must change the temperature element type (see
PART THREE, Section 3.2, subheading “Select TEMP ELEMENT Type”).
opera-
B. CONNECTING DC POWER
Refer to PART TWO, Section 3.2, 3.3, 3.4 or 3.5 to connect DC power to the transmitter.
C. CALIBRATING THE TRANSMITTER
The transmitter must be calibrated so that measured values will correspond to actual process values.
Preferably, use the “COND CAL” calibration method to enter the known value of a properly prepared
conductivity reference solution. (When using a sample of the process to calibrate, use the “SAMPLE
CAL” method to enter its known value determined by laboratory analysis or a comparison reading.)
Calibration Tip!
Each electrodeless conductivity sensor has a unique zero point and span. Consequently, when calibrating a sensor for the first time, always zero it according to step 1. Zeroing
provides the best possible measuring accuracy.
NOTE: An in-progress calibration can always be aborted by pressing the ESC key. After the
“ABORT: YES?” screen appears, do one of the following:
•
Press ENTER key to abort. After the “CONFIRM ACTIVE?” screen appears, press ENTER key
again to return the analog output to its active state (MEASURE screen appears).

Each sensor has a unique zero point and span. Therefore,
always ZERO the sensor in air if it is being calibrated for the
first time (PART THREE, Section 4.2). Specific methods to
calibrate for sensor span are available and dependent on
the transmitter’s configured measurement (conductivity, %

(NON-HAZARDOUS) AREA. THE TRANSMITTER
IS NOT INTRINSICALLY SAFE.
2. Mount the transmitter in a location that is:
➥
Clean and dry where there is little or no vibration.

2.2 Wall and Pipe
Mounting
Figure 2-1 illustrates how to wall or pipe mount the transmitter using the supplied GLI hardware kit. Determine the
mounting method, and attach the hardware as shown.
1. Fasten the wall/pipe adapter to the wall or pipe.
2. Using a blunt tool, open both cable entry knockout
holes in the back cover.
3. Insert-and-twist the back cover onto the installed
wall/pipe adapter, and tighten its screw to lock back
cover onto adapter.
4. Attach transmitter to back cover using its four captive screws.

2.3 Panel Mounting
☞
Figure 2-2 illustrates how to panel mount the transmitter
using the supplied GLI panel mount hardware kit.
1. Cut a 3.30-inch (84 mm) square cutout hole in panel.
2. Position panel-mount gasket over cutout in front of
panel, and place retainer plate behind panel with its
four threaded inserts facing away from back of panel.
3. Attach transmitter to retainer plate using its four captive
screws.
NOTE: If panel is too thick, remove captive screws
from transmitter, and use longer screws provided in hardware kit.

2.4 Integral Sensor
Mounting
☞
Figure 2-3 illustrates how to integrally mount the transmitter
onto a sensor using the supplied GLI mounting hardware kit.
1. Using a blunt tool, open knockout hole in bottom of
swivel ball for routing the sensor cable.
2. Attach swivel-mount assembly onto back end of sensor
using coupling provided with GLI sensor (only sensors
with “PRO1” suffix in their part number) or an appropriate-sized coupling that you provide.
3. Insert-and-twist back cover onto installed swivel-mount
assembly, and tighten its screw to lock back cover onto
swivel-mount assembly.
NOTE: To change mounting angle, loosen swivel-mount
assembly by lifting tab on bottom of swivel nut. Position to desired angle and re-tighten swivel nut.
4. Attach transmitter to back cover using its four captive screws.

Wiring Tip!
To comply with European Community (CE) electromagnetic
compatibility requirements, follow these general wiring guidelines:
1. Locate transmitter as far as possible from motors and other nonCE certified devices with excessive electromagnetic emissions.
2. Use GLI-specified ferrites and cables. Failure to do so may eliminate compliance. Locate all ferrites as close as possible to the
transmitter.
3. Loop these cables through the specified ferrite using the required
number of loops:
◆
DC Power Supply Cable (GLI 1W0980 two-conductor plus
shield): Connect cable shield to earth ground at the supply
end. Loop cable 4 times through ferrite (Fair-Rite Corp.
#2643102002 or equivalent).
◆
Sensor Cable: Keep cable shield as short as possible and
connect it to the SHIELD terminal. Loop cable 3-1/2 times
through ferrite (Fair-Rite Corp. #2643804502 or equivalent).
◆
Analog mA Output Cable (four-wire hookup only -- GLI
1W0980 two-conductor plus shield): Connect cable shield to
earth ground at the supply end. Loop cable 4 times through
ferrite (Fair-Rite Corp. #2643102002 or equivalent).

3.1 GLI Electrodeless
Conductivity Sensor
☞
☞
Refer to Figure 2-5 and connect the sensor (or interconnect) cable wires to Terminals 1 through 5 and to Terminal
7 on TB2, matching colors as indicated. (Terminal 6 is unused.)
Wiring Tip!
Route the sensor cable in 1/2-inch,
grounded metal conduit to protect it from moisture,
electrical noise, and mechanical damage.
For installations where the distance between sensor and
transmitter exceeds the sensor cable length, indirectly
connect the sensor to the transmitter using a junction box
and interconnect cable.
NOTE: Do not route the sensor cable in any conduit con-
taining AC or DC power wiring (“electrical noise”
may interfere with the sensor signal). Also, always
re-calibrate the system when the cable length between sensor and transmitter changes.
SENSOR
Depending on how transmitter is mounted, route the sensor
(or interconnect) cable into the transmitter as follows:
•
Wall/Pipe-mounted Transmitter: Route cable through left
side cable entry knockout hole in the back cover.
•
Panel-mounted Transmitter: Route cable behind panel to
the exposed TB2 terminal strip.
•
Integral Sensor-mounted Transmitter: Route cable
through swivel ball knockout hole and center hole in the
back cover. (Do not open left side cable entry knockout
hole in the back cover.)
