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.

Part I: 1-3
1 Introduction Model 6000B
Data Entry Keys: Six touch-sensitive membrane switches are used to
input data to the instrument via the alphanumeric VFD display:
• Left & Right Arrows Select between functions currently
displayed on the VFD screen.
• Up & Down Arrows Increment or decrement values of
functions currently displayed.
• Enter Moves VFD display on to the next screen in a series. If
none remains, returns to the Analyze screen.
• Escape Moves VFD display back to the previous screen in a
series. If none remains, returns to the Analyze screen.
Digital Meter Display: The meter display is a Light Emitting Diode
LED device that produces large, bright, 7-segment numbers that are legible
in any lighting. It is accurate across all analysis ranges. The 6000B models
produce continuous readout from 0-10,000 ppm and then switch to
continuous percent readout from 1-100 %.
Alphanumeric Interface Screen: The backlit VFD screen is an easyto-use interface between operator and analyzer. It displays values, options,
and messages for immediate feedback to the operator.
I/O Power Button: The red I/O button switches the instrument power
between I (ON) and O (a Keep-Alive state). In the O state, the instrument’s
circuitry is operating, but there are no displays or outputs.
CAUTION: The power must be disconnected to fully
disconnect power from the instrument. When
chassis is exposed or when access door is open
and power cable is connected, use extra care to
avoid contact with live electrical circuits .
Access Door: For access to the electronics and interface panel, the front
panel swings open when the latch in the panel is pressed all the way in with
a narrow gauge tool. Accessing the main circuit board and other electronics
requires unfastening the rear panel screws and sliding the unit out of the
case.
1.5 Control Unit Interface Panel
The Control Unit interface panel, shown in Figure 1-2, contains the
electrical terminal blocks for external inputs and outputs. The input/output
functions are described briefly here and in detail in the Installation chapter of
this manual.

2 Installation Model 6000B
Primary Input Power: The power supply in the Model 6000B 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
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 = Low Range, 0.5 V = Medium Range,
0.75 V = High Range, 1 V = Cal Range.
2-4: Part I
Teledyne Analytical Instruments
Photometric Analyzer Part I: Control Unit
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 = Low Range, 12 mA = Me-
dium Range, 16 mA = High Range, 20 mA = Cal
Range.
Figure 2-5: Analog Output Connections
Examples:
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.

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).

The connectors are:
Threshold Alarm 1: • Can be configured as high (actuates when
concentration is above threshold), or low
(actuates when concentration is below thresh old).
• Can be configured as fail-safe or non-fail-safe.
• Can be configured as latching or nonlatching.
• Can be configured out (defeated).
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.

2 Installation Model 6000B
To reset a System Alarm during installation, discon-
nect power to the instrument and then reconnect it
Further detail can be found in chapter 3, section 4-5.
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.)
Remote Calibration Protocol: To properly time the Digital Remote
Cal Inputs to the Model 6000B 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:
2-8: Part I
Teledyne Analytical Instruments
Photometric Analyzer Part I: Control Unit
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 connector (paragraph 3.3) 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 three ranges are assigned to relays in ascending order—Low range
is assigned to RANGE 1 ID, Medium range is assigned to RANGE 2 ID,
and High range is assigned to RANGE 3 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.

The data sent is status information, in digital form, updated every two
seconds. Status is reported in the following order:
• The concentration in percent
• The range is use (HI< MED< LO)
• The span of the range 0-100%, etc)
• Which alarm - if any - are disabled (AL-x DISABLED)
• Which alarms - if any - are tripped (AL-x ON)
Each status output is followed by a carriage return and line feed.
Three input functions using RS-232 have been implemented to date.
They are described in Table 2-4.

Operation
3.1 Introduction
Although the Model 6000B is usually programmed to your application at
the factory, it can be further configured at the operator level, or even, cautious-
ly, 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 Data Entry and Function

monitors the thermal conductivity of the sample, displays the
percent or parts-per-million of target gas or contamination, and
warns of any alarm conditions.
• 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
• Initiate a Self-Test
Three of the subfunctions do auxiliary tasks:
• Checking model and software version
• Adjust electronic filter of the signal
• Display more subfunctions
• Display negative readings
Two of these are for programming/reprogramming the analyzer:
• Define gas applications and ranges (Refer to programming
section, or contact factory.)
• 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 three analysis ranges that can be
switched automatically with autoranging or used as individual
fixed ranges.
Any function can be selected at any time by pressing the appropriate button
(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

3.3 The System Function
The subfuctions 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.
• FILSOL: Select Span/Zero flag (filter) or Span/Zero solenoid
valve for calibration method.
• 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.
• APPLICATION: Used to define the analysis ranges and
application (gas used).
• MODEL: Displays model number and software version.
• OUTPUT: 4-20 MA: Adjust 4 and 20 mA output.
• SHOW_NEG: Whether to display negative readings or not; affects
analog output too. No negative readings is the default.
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.
