IMPORTANT SAFETY INFORMATION
This analyzer 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:
•
Opening the analyzer door exposes you to line power voltage, if present, at terminals on TB2 and TB3
inside the enclosure. This may be hazardous. Always remove line power before entering this area in
the analyzer. However, the analyzer door assembly contains only low voltage and is completely safe
to handle.
•
Wiring or repairs should only be performed by qualified personnel and only to an unpowered analyzer.
•
Whenever it appears that analyzer safety is questionable, disable the analyzer to ensure against any
unintended operation. For example, an unsafe condition is likely when:
1) The analyzer appears visibly damaged.
2) The analyzer fails to operate properly or provide the intended measurements.
3) The analyzer has been stored for long periods at temperatures above 158°F (70°C).
•
This analyzer must be installed by specially trained personnel in accordance with relevant local codes
and instructions contained in this operating instruction manual. Observe the analyzer’s technical
specifications and input ratings. If one line of the line power mains is not neutral, use a double-pole
mains switch to disconnect the analyzer.

temperature element, or for fixed MANUAL temperature compensation, you must change the
temperature element type (see PART THREE, Section 4.2, subheading “Select TEMP
ELEMENT Type”).
B. CONNECTING LINE POWER
Important:
Follow the instructions in PART TWO, Section 3.5 to connect line power to the analyzer.

D. CALIBRATING THE ANALYZER
The analyzer 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
measuring accuracy of conductivity and temperature. Besides, DRY-CAL is actually a normal part of

configuring the sensor characteristics during initial startup, and

This method also automatically sets the analyzer 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 5.1.
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, and eliminates any discrepancy between Sensor A
and B measurement channels.
DRY-CAL calibration, routinely attained while configuring the analyzer for sensor characteristics, requires entry of the sensor’s GLI-certified “CELL K” value and temperature “T FACTOR” which are
unique to each sensor. When using two sensors, enter each unique set of values using respective
sensor menu screens.
1. Zero the sensor if it is being calibrated for
the first time. If not, disregard this step and perform
steps 2 through 14.

Calibration Methods
Rev. 5-1000 Model C53 Conductivity Analyzer (universal-mount 1/2 DIN)
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.
It is highly recommended to calibrate the analyzer using GLI’s
DRY-CAL method, which is simple to do and eliminates the
need to prepare a reference solution. However, the analyzer
can be traditionally “wet” calibrated. For calibration details, refer to PART THREE, Sections 5.2 and 5.3 or 5.4. Each analog
output mA value can also be calibrated (Section 5.5).

PART ONE - INTRODUCTION SECTION 1 - GENERAL INFORMATION
Analog Outputs
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 one of the following:
•
Measured Sensor A conductivity, resistivity or TDS.
•
Measured Sensor A temperature.
•
Measured Sensor B conductivity, resistivity or TDS.
•
Measured Sensor B temperature.
•
*Calculated Sensor A and B measurement (% reject,
% pass, ratio A/B, ratio B/A, diff. A-B, or diff. B-A).
*An analog output can only represent the calculated measurement when
two sensors are used and the analyzer has been correctly configured for
CALCULATION.
Parameter (or calculated measurement) values can be entered to define the endpoints at which the minimum and
maximum analog output values are desired (range expand).
For analog output setup details, see PART THREE, Section
4.5.
During calibration, both analog outputs can be selected to:

The analyzer may have up to four electromechanical relays,
all with SPDT contacts. Each relay can be set to function as
a CONTROL, ALARM or STATUS relay. CONTROL and
ALARM relays can be assigned to be driven by one of these:
•
Measured Sensor A conductivity, resistivity or TDS.
•
Measured Sensor A temperature.
•
Measured Sensor B conductivity, resistivity or TDS.
•
Measured Sensor B temperature.
•
*Calculated Sensor A and B measurement (% reject,
% pass, ratio A/B, ratio B/A, diff. A-B, or diff. B-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.
Refer to PART THREE, Section 4.6 for relay setup details.
1.2 Modular Construction
1.3 Retained
Configuration Values
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.
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.

electromagnetic compatibility requirements, follow these
general wiring guidelines:
1. Keep all cable shields as short as possible inside
the analyzer, and connect them to the ground terminals provided. Performance may be improved by
using cable glands that enable the shield to directly
contact the analyzer chassis.
2. Use Steward ferrite 28 B0590-000 or equivalent on
the sensor cable -- two turns required.
3. In harsh conducted RF conditions, connect the earth
ground of the analyzer to a local, known earth
ground source.
