1 Introduction Model 5000B
1.4 Operator Interface
All controls and displays on the standard 5000B 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.
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.
1-6: Part I
-Zero This function zeros the instrument.
-Alarms This functions sets the alarm
preferences.

1 Introduction Model 5000B
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.

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: Current increases linearly with increasing sample
concentration, from 4 mA at 0% to 20 mA at full scale 100%. (Full scale = 100% of programmed 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.

Range Voltage (V) Current (mA)
Range 1 0.25 8
Range 2 0.50 12
Range 3 0.75 16
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 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.
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
2-6: Part I
Teledyne Analytical Instruments
Photometric Analyzer Part I: Control Unit
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 5000B 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.
Teledyne Analytical Instruments
Part I: 2-7
1 Introduction Model 5000B
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.

Operation
3.1 Introduction
Although the Model 5000B 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 Data Entry and Function Buttons
Data Entry Buttons: The < > buttons select options from the menu
currently being displayed on the VFD screen. The selected option blinks.
When the selected option includes a modifiable item, the DÑ arrow
buttons can be used to increment or decrement that modifiable item.
Teledyne Analytical Instruments
Part I 3-1
3 Operation/Control Unit Model 5000B
The Enter button is used to accept any new entries on the VFD screen.
The Escape button is used to abort any new entries on the VFD screen that are not yet accepted by use of the Enter button.
Figure 3-1 shows the hierarchy of functions available to the operator via the
function buttons. The six functions of the buttons on the analyzer are:
Analyze. This is the normal operating mode. The analyzer monitors
the concentration of the sample, displays the percent or parts-per­million of target fluid 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 fluid applications and ranges (Refer to programming section, or contact factory.)
Use the Curve Algorithm to linearize output. (Refer to programming section, or contact factory.)
