IMPORTANT SAFETY INFORMATION
This analyzer is compliant with safety standards as outlined in:
European Community low voltage directive (EN 61010-1)
Please read and observe the following:
•Opening the analyzer door exposes you to line power voltage, if present, at terminals TB5 and TB6 in
the base of 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.
•Install this analyzer in accordance with relevant local codes and instructions contained in this operating
manual. Also, note and comply with 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.
•Whenever it appears that analyzer safety is questionable, disconnect line power from 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 140°F (60°C).
•Only qualified personnel should perform wiring or repairs, and only when the analyzer is not powered.

1.1 Capability Highlights

Advanced Diagnostics
Data Logbook
Passcode-protected
Access
Calibration Methods
Dual Analog Outputs
The analyzer is equipped with one of two types of sensor
input (scaling) printed circuit boards. One board enables
any GLI Differential Technique pH sensor to be used with
the analyzer. The other is provided when using a conven-
tional combination electrode or electrode pair.
In addition to displaying pH, you can scroll the lower line
on the MEASURE screen using the
×
×
or
Ø
Ø
key to show
other important system information. See operational specifi-
cations in PART ONE, Section 2.1 for a complete listing.
True predictive diagnostics can forecast the date for end-of-
sensor life. Reactive diagnostics alerts you to changes in
vital sensor data including impedance, zero, and slope for
the measuring and reference electrodes. All diagnostics
data are logged and can be set to drive alarms. Analyzer
self-checks verify memory, keypad, and display status.
The analyzer logbook records up to 100 system events in-
cluding calibrations, warn and fail messages, power-up/
power-down, relay overfeed timer “time outs”, and configu-
ration activity. Each event is logged with its date and time of
occurrence.
For security, you can create a passcode to restrict access to
configuration settings to only authorized personnel. See
PART THREE, Section 5.13 for details.
Four methods are available to calibrate the analyzer for pH.
See PART THREE, Section 4.4 for details. Temperature
can also be calibrated. However, since the analyzer is
factory-calibrated for high, temperature measurement accu-
racy, this feature is typically not needed.
The analyzer provides two sets of analog outputs. Each set
consists of one 4-20 mA and one 0-5 VDC/0-1 mA signal.
Each output set can represent the measured pH or tem-
perature. When the analyzer is equipped with the optional
PID controller, Output 1 can be set to represent the con-
troller output (0-100%). Output 2 can be selected to provide

PID Controller
1.2 Modular Construction
a dedicated non-variable alarm signal of only 4 mA or 20
mA instead of its normal proportional output. When the
analyzer detects that one of the 4-20 mA loops is open, it
displays a “Current Load High”diagnostic message.
The analyzer has three relays. They may be the standard
electromechanical relays, or the optional solid state AC or
solid state DC relays.
The analyzer has three TTL (NAMUR) outputs. They can be
used to represent the established German NAMUR Com-
mittee standards for measurement and control:
•TTL Output A: Instrument is “off line”for calibration or
maintenance.
•TTL Output B: One or more software or system alarms
are in the “warn”state.
•TTL Output C: One or more software or system alarms
are in the “fail”state.
Each enabled TTL output can be set to operate as “fail
safe,”and assigned an “on delay”time.
The states of the analog outputs, relays, and TTL outputs
can be separately transferred to user-preset states. This is
especially useful during calibration or when performing
maintenance. See PART THREE, Section 5.9 for details.
The optional PID controller has a selectable algorithm (ISA
or velocity), all tuning functions including manual reset, and
timers for 0% and 100% controller output. In addition to its
normal automatic operation, the controller can be operated
manually using screens in the MAINT menu.
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 TB5/TB6.
WARNING:
REMOVE LINE POWER BEFORE NEARING THIS
AREA TO AVOID ELECTRICAL SHOCK.

Serial Number
1.5 EMI/RFI Immunity
All user-entered configuration values are retained indefi-
nitely, even if power is lost or turned off. The non-volatile
analyzer memory does not require battery backup.
Labels with the analyzer serial number are located on the
top of the enclosure and backside of the door assembly.
You can display the serial number by pressing the DIAG
key, selecting “Device Description,”and pressing ENTER.
The standard analyzer has an aluminum enclosure and fil-
ters for line power and low-level signals, all of which provide
substantial protection from most normally encountered
electromagnetic interference. Some applications, however,
may require additional protection. In these cases, the ana-
lyzer may be equipped with the EMI-hardened option that
includes extra shielding, special shielded glass for the dis-
play, and CE certification. (An EMI upgrade kit is available
for on-site retrofitting.) This protection exceeds U.S. stan-
dards and meets European IEC 801-series testing for
electromagnetic and radio frequency emissions and sus-
ceptibility. Refer to Figure 1-1 and the specifications in
Section 2.1 for more information.

Sensor-to-Analyzer Distance:
GLI Differential Tech. Sensor .. 3000 ft. (914 m) maximum (distances greater
than 500 ft./152 m may degrade sensor im-
pedance diagnostic readings)
Conventional Comb. Elect....... 100 ft. (30 m) maximum with electrode cable
capacitance of less than 30 pF/foot
Power Requirements .................. 105-250 VAC, 50/60 Hz. (20 VA max.); no
jumper or switch settings required
pH Calibration Methods:
Arbitrary (1 or 2-point) ............ Enter known value of buffer for each point
Pre-defined (1 or 2-point) ........ Automatic calibration and buffer recognition
using buffers from one of these built-in
buffer sets:
•GLI Buffers: 4.00, 7.00, and 10.00 pH
•NBS Buffers: 1.68, 4.01, 6.87, 9.18, and 12.45 pH
•DIN 19267 Buffers: 1.09, 4.65, 6.79, 9.23, and 12.75 pH
•Merck/Riedel de Haën Buffers: 2.00, 4.00, 7.00, 9.00, and 12.00 pH
•Ingold Buffers: 2.00, 4.01, 7.00, and 9.21 pH
Sample (1 or 2-point).............. Enter known value of sample determined by
laboratory analysis or comparison reading
Wash/Cal ............................... When used with a GLI Cal-Clean™system or
other appropriate hardware, initiates auto-
matic wash/cal cycle operation using pre-
defined buffer values from a selected built-in
buffer set (see five buffer sets listed above)
TTL Auxiliary Inputs (two)........... Dedicated for use only with automatic
GLI Cal-Clean™System
Outputs: Analog* (standard)...... Two sets (1 and 2) each with 4 microampere
(12-bit) resolution; each set consists of:
Isolated 4-20 mA (900 ohms max. load)
- and -
Isolated 0-5 VDC (1 megohm min. load)/
0-1 mA (100 ohms max. load)
*Each analog output set can be assigned to represent the measured pH or
temperature. When the analyzer has the optional PID controller, Output 1
can be set to represent the controller output (0-100%). Output 2 can be se-
lected to provide a special dedicated non-variable alarm signal (only 4 mA
or 20 mA) instead of its normal proportional output. pH or temperature val-
ues can be entered to define the endpoints at which the minimum and
maximum output values are desired (range expand). During calibration,
both output sets can be selected to hold their present values, transfer to
user-preset values to operate control elements by an amount corresponding
to those values, or remain active to respond to the measurement. The dis-
play indicates an error message for each output current loop that is open.
TTL (standard)............ Three isolated auxiliary TTL-level outputs for:
A. Use with automatic Cal-Clean™System
B. Use as NAMUR diagnostics:
TTL Output A: Instrument is “off line”for
calibration or maintenance.
TTL Output B: One or more software or
system alarms are in the “warn”state.
TTL Output C: One or more software or
system alarms are in the “fail”state.
PID Controller ............. One isolated 4-20 mA (uses analog out 1);
(optional) 900 ohms max. load

PART TWO - INSTALLATION
SECTION 1
After unpacking, it is recommended to save the shipping
carton and packing materials in case the instrument must be
stored or re-shipped. Inspect the equipment and packing
materials for signs of shipping damage. If there is any evi-
dence of damage, notify the transit carrier immediately.
SECTION 2
2.1 Location 1. It is recommended to locate the analyzer as close as
possible to the installed sensor:
•GLI Differential Technique Sensor: The maximum
allowable distance between this type of sensor and
the analyzer is 3000 feet (914 m). However, dis-
tances greater than 500 feet (152 m) may degrade
the electrode impedance diagnostics of the ana-
lyzer.
•Conventional Combination Electrode: The maxi-
mum allowable distance between this type of
electrode and the analyzer is 100 feet (30 m). A
preamp may be used to extend this distance to 3000
feet (914 m), but the preamp must be within 100 feet
(30 m) of the electrode. (Important: A preamp will
eliminate the electrode impedance diagnostics ca-
pability of the analyzer.)
2. Mount the analyzer in a location that is:
➥Clean and dry where there is little or no vibration.
➥Protected from corrosive fluids.
➥Within ambient temperature limits (-22 to +140°F;
-30 to +60°C).
CAUTION:
EXPOSING THE ANALYZER TO DIRECT
SUNLIGHT MAY INCREASE THE OPERATING
TEMPERATURE ABOVE ITS SPECIFIED
LIMIT.
