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).
•
Installed this transmitter in accordance with relevant local codes and instructions contained in this
operating manual. Also, note and comply with the transmitter’s technical specifications and ratings.
HELPFUL IDENTIFIERS

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 resistivity 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 TW O, Section 2), connect the GLI enhanced
performance contacting conductivity sensor, matching wire colors to terminals as indicated:
Sensor Wire Colors Connect To TB2
Red Terminal 1
No connection (unused) Terminal 2
Inner and Outer Shield Wires Terminal 3
White Terminal 4
Blue Terminal 5
No connection (unused) Terminal 6
Black Terminal 7
2. The transmitter is supplied factory-set for automatic temperature compensation using the Pt
1000 ohm temperature element built into GLI enhanced performance contacting 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.
It can be traditionally “wet” calibrated. However, since measured conductivity is greatly affected by
small changes in temperature, GLI strongly recommends
using its DRY-CAL method for highest
measuring accuracy of conductivity and temperature. Besides, DRY-CAL is actually a normal part of
configuring the sensor characteristics during initial startup, and
conductivity reference solutions.
This method also automatically sets the transmitter measuring
DRY-CAL eliminates the need for
range to match the inherent range of the sensor’s cell constant. For more details about the benefits
of DRY-CAL, refer to the “Calibration Tip!” in PART THREE, Section 4.1.
NOTE: DRY-CAL eliminates the need for periodic re-calibration! The only requirement, depending on
the application, may be to periodically clean the sensor. Only when the sensor is replaced is
it necessary to perform a new DRY-CAL calibration.
Calibration Tip!
Each contacting conductivity sensor has a unique zero point and offset. Consequently, when calibrating a sensor for the first time, always zero it according to step 1. Zeroing
provides the best possible measuring accuracy.
DRY-CAL calibration, routinely attained while configuring the transmitter for sensor characteristics,
requires entry of the sensor’s GLI-certified “CELL K” value and temperature “T FACTOR” which are
unique to each sensor.

Calibration Methods
The MEASURE screen (normal display mode) can provide

Measured temperature (°C or °F)
•
Measured conductivity, resistivity or TDS, and temperature
•
Measured analog output 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 3.5 for details.
It is highly recommended to calibrate the transmitter using
GLI’s simple DRY-CAL method, which eliminates the need
to prepare a reference solution. However, the transmitter
can be traditionally “wet” calibrated. For calibration details,
refer to PART THREE, Sections 4.2 and 4.3 or 4.4. The analog
output loop can also be calibrated (Section 4.4).

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.

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 appropriately-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!
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:

◆
To comply with European Community (CE) electromagnetic
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).
