1.3 Main Features of the Analyzer
The Model 6600 Photometric Analyzer is sophisticated yet simple to
use. The main features of the analyzer include:
• A 2-line alphanumeric display screen, driven by microprocessor
electronics, that continuously prompts and informs the operator.
• High resolution, accurate readings of concentration from low
ppm levels through to 100%. Large, bright, meter readout.
• Versatile analysis over a wide range of applications.
• Microprocessor based electronics: 8-bit CMOS microprocessor
with 32 kB RAM and 128 kB ROM.
• Three user definable output ranges (from 0-1 ppm through
0-100 %) allow best match to users process and equipment.
• Calibration range for convenient zeroing or spanning.
• Auto Ranging allows analyzer to automatically select the proper
preset range for a given measurement. Manual override allows
the user to lock onto a specific range of interest.
• Two adjustable concentration alarms and a system failure alarm.
• Extensive self-diagnostic testing, at startup and on demand, with
continuous power-supply monitoring.
• RS-232 serial digital port for use with a computer or other digital
communication device.
• Analog outputs for concentration and range identification.
(0-1 V dc standard, and isolated 4–20 mA dc)
• Superior accuracy.
• Internal calibration-Manual or Automatic (optional).
1.4 Operator Interface
All controls and displays on the standard 6600 are accessible from
outside the housing. The instrument has two simple operator controls. The
operator has constant feedback from the instrument through an alphanumeric
display, and a digital LED meter. The displays and controls are described
briefly here and in greater detail in chapter 3. See Figure 1-1.

1.4.1 UP/DOWN Switch
The UP/DOWN switch is used to select between any subfunctions displayed
on the VFD screen such as in the main menue, the system menue, the Alarm
menue, etc. When modifiable values are displayed on the VFD, the UP/DOWN
switch can be used to increment or decrement the values.
1.4.2 ESCAPE/ENTER Switch
The ESCAPE/ENTER switch is used to input the data, to enter a function,
or to exit a function displayed in the alphanumeric display:
• Escape Moves VFD display back to the previous screen in a
series. If none remains, returns to Analyze mode screen.
• Enter Within a menue: the funtion selected is entered moving on
to the next screen in a series.
WARNING:
The power cable must be disconnected to fully remove power
from the instrument.
With Value selected: Enters the value into the analyzer as
data. Advances cursor on VFD to the next operation.
In the Analyze mode: it calls the main menue. Functions
called out by the main menue:
-System This function is a menu that calls a number
of functions that regulate the analyzer
operation.
-Span This function spans the instrument.
-Zero This function zeros the instrument.
-Alarms This functions sets the alarm preferences.
-Range This function selects whether analyzer is
autoranging or locked on one range.

Figure 2-3: Interface Panel of the Model 6600 Control Section
For safe connections, ensure that no uninsulated wire extends
outside of the terminal blocks. Stripped wire ends must insert completely
into terminal blocks. No uninsulated wiring should come in contact with
fingers, tools or clothing during normal operation.
Primary Input Power: The power supply in the Model 6600 will
accept a 115 Vac, 50/60 Hz power source. See Figure 2-4 for detailed
connections.
DANGER: Power is applied to the instrument's circuitry as
long as the instrument is connected to the power
source. The standby function switches power on or
off to the displays and outputs only.
115VAC

Figure 2-4: Primary Input Power Connections
Teledyne Analytical Instruments
Oil in Water Analyzer Part I: Control Section
Fuse Installation: The fuse holders accept 5 x 20 mm, 4.0 A, T
type (slow blow) fuses. Fuses are not installed at the factory. Be sure to
install the proper fuse as part of installation (See Fuse Replacement in
chapter 4, maintenance.)
Analog Outputs: There are eight DC output signal connectors on
the ANALOG OUTPUTS terminal block. There are two connectors per
output with the polarity noted. See Figure 2-5.
The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing sample con-
centration, from 0 V at 0% to 1 V at 100%. (Full
scale = 100% programmed range.)
0–1 V dc Range ID: 0.25 V = Range 1, 0.5 V = Range 2, 0.75 V =
Range 3.
4–20 mA dc % Range: (-M Option) Current increases linearly with increas-
ing sample concentration, from 4 mA at 0% to 20
mA at full scale 100%. (Full scale = 100% of
programmed range.)
4–20 mA dc Range ID: (-M Option) 8 mA = Range 1, 12 mA = Range 2,
16 mA = Range 3.
Examples:
Figure 2-5: Analog Output Connections
Teledyne Analytical Instruments
Part I: 2-3
2 Installation Model 6600
The analog output signal has a voltage which depends on the sample
concentration AND the currently activated analysis range. To relate the
signal output to the actual concentration, it is necessary to know what range
the instrument is currently on, especially when the analyzer is in the
autoranging mode.
The signaloutput for concentration is linear over currently selected
analysis range. For example, if the analyzer is set on a range that was
defined as 0-10 %, then the output would be as shown in Table 2-1.
Table 2-1: Analog Concentration Output-Examples
Concentration Voltage Signal Current Signal
% Output (V dc) Output (mA dc)
0 0.0 4.0
1 0.1 5.6
2 0.2 7.2
3 0.3 8.8

7 0.7 15.2
8 0.8 16.8
9 0.9 18.4
10 1.0 20.0
To provide an indication of the range, a second pair of analog output
terminals are used. They generate a steady preset voltage (or current when
using the current outputs) to represent a particular range. Table 2-2 gives the
range ID output for each analysis range.

Alarm Relays:
There are three alarm-circuit connectors on the alarm relays block
(under RELAY OUTPUTS) for making connections to internal alarm relay
contacts. Each provides a set of Form C contacts for each type of alarm.
Each has both normally open and normally closed contact connections. The
contact connections are indicated by diagrams on the rear panel. They are
capable of switching up to 3 ampers at 250 V AC into a resistive load
(Figure 2-6).

Threshold Alarm 2: • Can be configured as high (actuates when concen-
tration is above threshold), or low (actuates when
concentration is below threshold).
• Can be configured as fail-safe or non-fail-safe.
• Can be configured as latching or nonlatching.
• Can be configured out (defeated).
System Alarm: Actuates when DC power supplied to circuits is
unacceptable in one or more parameters. Permanently
configured as fail-safe and latching. Cannot be defeated. Actuates if self test fails.
To reset a System Alarm during installation, disconnect power to the instrument and then reconnect it
Further detail can be found in chapter 3, section 3-5.
Digital Remote Cal Inputs
Remote Zero and Span Inputs: The REMOTE SPAN and RE-
MOTE ZERO inputs are on the DIGITAL INPUT terminal block. They
accept 0 V (OFF) or 24 V dc (ON) for remote control of calibration (See
Remote Calibration Protocol below.)
Zero: Floating input. 5 to 24 V input across the + and – terminals
puts the analyzer into the ZERO mode. Either side may be
grounded at the source of the signal. 0 to 1 volt across the
terminals allows ZERO mode to terminate when done. A
synchronous signal must open and close the external zero
valve appropriately. See Remote Probe Connector at end of
section 3.3. (With the -C option, the internal valves automatically operate synchronously).
Span: Floating input. 5 to 24 V input across the + and – terminals
puts the analyzer into the SPAN mode. Either side may be
grounded at the source of the signal. 0 to 1 volt across the
terminals allows SPAN mode to terminate when done. A
synchronous signal must open and close the external span
valve appropriately. See Remote Probe Connector at end of
section 3.3. (With the -C option, the internal valves automatically operate synchronously.)
Cal Contact: This relay contact is closed while analyzer is spanning
and/or zeroing. (See Remote Calibration Protocol below.)
2-6: Part I
Teledyne Analytical Instruments
Oil in Water Analyzer Part I: Control Section
Remote Calibration Protocol: To properly time the Digital Remote
Cal Inputs to the Model 6600 Analyzer, the customer's controller must
monitor the Cal Relay Contact.
When the contact is OPEN, the analyzer is analyzing, the Remote Cal
Inputs are being polled, and a zero or span command can be sent.
When the contact is CLOSED, the analyzer is already calibrating. It
will ignore your request to calibrate, and it will not remember that request.
Once a zero or span command is sent, and acknowledged (contact
closes), release it. If the command is continued until after the zero or span is
complete, the calibration will repeat and the Cal Relay Contact (CRC) will
close again.
For example:
1) Test the CRC. When the CRC is open, Send a zero command
until the CRC closes (The CRC will quickly close.)
2) When the CRC closes, remove the zero command.
3) When CRC opens again, send a span command until the CRC
closes. (The CRC will quickly close.)
4) When the CRC closes, remove the span command.
When CRC opens again, zero and span are done, and the sample is
being analyzed.
Note: The Remote Bench terminal strip (section 3.6 Part III) provides
signals to ensure that the zero and span gas valves will be
controlled synchronously.
Range ID Relays: Four dedicated RANGE ID CONTACT relays .
The first four ranges are assigned to relays in ascending order—Range 1 is
assigned to RANGE 1 ID, Range 2 is assigned to RANGE 2 ID, Range 3
is assigned to RANGE 3 ID, and Range 4 is assigned to RANGE 4 ID.
Network I/O: A serial digital input/output for local network protocol.
At this printing, this port is not yet functional. It is to be used in future
versions of the instrument.
RS-232 Port: The digital signal output is a standard RS-232 serial
communications port used to connect the analyzer to a computer, terminal, or
other digital device. The pinouts are listed in Table 2-3.

Remote Bench and Solenoid Valves: The 6600 is a single-chassis
instrument. However, the REMOTE BENCH and SOLENOID RETURN
connectors are provided on the interface PCB. The Remote Bench is wired
at the factory as well as any optional solenoid valves included in the system.
2.3 Testing the System
After The Control/Analysis Unit is both installed and interconnected,
and the system gas and electrical connections are complete, the system is
ready to test. Before plugging the unit into its power sources:
• Check the integrity and accuracy of the gas connections. Make
sure there are no leaks.
• Check the integrity and accuracy of all electrical connections.
Make sure there are no exposed conductors
• Check that sample pressure typically between 0 and 30 psig,
according to the requirements of your process.
• Turn homogenizer power potentiometer fully counter-clockwise
(OFF), see section 3.3.8 for operation of homogenizer.
Warning: Do not operate the “ultrasonic homogenizer” in the
instrument for more than one (1) minute without a
liquid sample properly flowing through the homogenizer.
Power up the system, and test it by performing the following operation:
1. Repeat the Self-Diagnostic Test.
2. Zero the instrument.
3. Span the instrument.
For steps 2 and 3, refer to part II for gas calibration, and part III for Oil
in Water application.

Operation
3.1 Introduction
Although the Model 6600 is usually programmed to your application at the
factory, it can be further configured at the operator level, or even, cautiously,
reprogrammed. Depending on the specifics of the application, this might include
all or a subset of the following procedures:
• Setting system parameters:
• Establish a security password, if desired, requiring Operator
to log in (secure in safe file for referrence).
• Establish and start an automatic calibration cycle, if desired.
• Routine Operation:
• Calibrate the instrument.
• Choose autoranging or select a fixed range of analysis.
• Set alarm setpoints, and modes of alarm operation (latching,
fail-safe, etc).
• Program/Reprogram the analyzer:
• Define new applications.
• Linearize your ranges.
If you choose not to use password protection, the default password is
automatically displayed on the password screen when you start up, and you
simply press Enter for access to all functions of the analyzer.
3.2 Using the Controls
To get the proper response from these controls, turn the control toward the
desired action (ESCAPE or ENTER—DOWN or UP), and then release it.
Turn-and-release once for each action. For example, turn-and-release twice
toward UP to move the VFD screen two selections upwards on the list of
options (menu).
Teledyne Analytical Instruments
Part I 3-1
3 Operation Model 6600
The item that is blinking on the screen is the item that is currently selectable
by choosing ENTER (turn-and-release toward ENTER with the ESCAPE/
ENTER control).
In these instructions, to ENTER means to turn-and-release toward ENTER, and To ESCAPE means to turn-and-release towards ESCAPE. To scroll
UP (or scroll DOWN) means to turn-and-release toward UP (or DOWN) as
many times as necessary to reach the required menu item.
3.2.1 Mode/Function Selection
After the instrument has been powered up, and its initilization routine
performed, the instrument will settle in the Analyze mode. To call up the Main
menu from the Analyze mode, toggle the Enter switch. To return to the Analyze
mode, toggle the Escape switch. The Main menu screens looks as shown
below:
SYSTEM SPAN ZERO
ALARM RANGE STBY
The Main menue screen is the top level in a series of screens used to
configure the analyzer. The DOWN/UP selects the different options displayed
in the VFD screen. The selectable option blinks on the VFD screen when you
reach the desired option, toggle the Enter switch.
The Escape switch takes you back up to hierarchy of screens until you
return back to the Analyze screen mode. Here is a brief description of the Main
Menu:
• System. The system function consists of nine subfunctions.
Four of these are for ordinary setup and operation:
• Setup an Auto-Cal
• Assign Passwords
• Log out to secure system

• Use the Curve Algorithm to linearize output. (Refer to
programming section, or contact factory.)
• Zero. Used to set up a zero calibration.
• Span. Used to set up a span calibration.
• Alarms. Used to set the alarm setpoints and determine whether
each alarm will be active or defeated, HI or LO acting, latching,
and/or fail-safe.
• Range. Used to set up four analysis ranges that can be switched
automatically with autoranging or used as individual fixed
ranges.
Any function can be selected at any time in the analyze mode (unless
password restrictions apply). The order as presented in this manual is
appropriate for an initial setup.
Each of these functions is described in greater detail in the following procedures. The VFD screen text that accompanies each operation is reproduced, at
the appropriate point in the procedure, in a Monospaced type style.
3.3 The System Function
The subfunctions of the System function are described below. Specific
procedures for their use follow the descriptions:
• Dig_Filt: Adjust how much digital filtering should be on the
signal
• SELF-TEST: Performs a self-diagnostic test to check the integrity
of the power supplies, outputs, detector signal and preamplifier.
• PWD: Login security system for accessing to the setup functions.
• LOGOUT: Prevents an unauthorized tampering with analyzer
settings.
• AUTOCAL: Set the automatic calibrated timer schedule for Zero
and Span cycling.
• HMGNZR: Turn Ultrasonic homogenizer ON and OFF on the
analyze mode.
• TRACK: Set the system reading to be held or followed by the
concentration “gas or filter” during calibration.
• CAL-HOLD-TIMER: Set the timing for calibration holding and
timing for the sample reading after return to analyze mode.
• ALGORITHM: Linearize the output for nonlinear characteristic.

Oil in Water Analyzer Operation 3
• APPLICATION: Used to define the analysis ranges and application
(gas used).
• MODEL: Displays model number and software version.
• OUTPUT_CAL: 4-20 MA: Adjust 4 and 20 mA output.
The hierarchy of the system menu is shown in figure 3-1.
3.3.1 Setting up an AUTO-CAL
When proper automatic valving is connected, the Analyzer can cycle itself
through a sequence of steps that automatically zero and span the instrument.
Note: Before setting up an AUTO-CAL, be sure you understand the
Zero and Span functions as described in section 4.4, and
follow the precautions given there.
Note: If you require highly accurate AUTO-CAL timing, use external
AUTO-CAL control where possible. The internal clock in the
Model 6600 is accurate to 2-3 %. Accordingly, internally scheduled calibrations can vary 2-3 % per day.
To setup an Auto–Cal cycle:
Choose System from the main manu. TheVFD will display five subfunc-
tions.

Enter to turn ON the SPAN and/or ZERO cycles (to activate AUTO–CAL).
Use the UP/DOWN to toggle the field between ON and OFF. Press Enter to
return to The AUTO-CAL menu. You should be able to see that the screen has
been updated with your new input. Escape to return to the System menu.
For Oil & Water Samples only setting of the Zero schedule is needed. Instrument will automatically perform a Span at the end of a scheduled Zero.
If instrument is turned off, the next time the instrument is powered, the
instrument will automatically perform a calibration cycle after 3 minutes of
entering the sample mode if AUTOCAL functions were on prior to shut down.
3.3.2 Password Protection
Before a unique password is assigned, the system assigns TAI by default.
This password will be displayed automatically. The operator just uses the Enter
switch to be allowed total access to the instrument’s features.
If a password is assigned, then setting the following system parameters can
be done only after the password is entered: alarm setpoints, assigning a new
password, range/application selections, and curve algorithm linearization.
(APPLICATION and ALGORITHM are covered in the programming section.)
However, the instrument can still be used for analysis or for initiating a self-test
without entering the password. To defeat security the password must be
changed back to TAI.
NOTE: If you use password security, it is advisable to keep a copy of
the password in a separate, safe location.
3.3.2.1 Entering the Password
To install a new password or change a previously installed password, you
must key in and ENTER the old password first. If the default password is in
effect, using ENTER three times will enter the default TAI password for you.
Enter the System menu...

password has been previously installed.
