NOTES:

Introduction
1-1
Introduction
The OS4000 series high speed fiber optic infrared line of transmitters measures a
temperature range of 100ºC (212ºF) to 1600ºC (2912ºF) using nine different Fiber
Optic Lens Probes, three Polymer Bolt probes, and twelve Glass & Quartz tip
assemblies. The Lens Probe offers 3 standard optical field of views at 3 standard
fiber optic cable lengths. The transmitter offers many standard features such as
adjustable Emissivity from 0.05 to 0.99, adjustable Response time, 4 different
analog output options, 2 way RS232 communication, high & low alarm voltage
outputs, built-in Laser sighting for positioning the Lens Probe, and mounting
bracket & mounting nuts.
The OS4000 series can be ordered with one analog output and an optional Relay
contact closure outputs. The following describes the transmitter model number
selection:
OS4001-* - **
Add:
* - MV for 1 mV/Degree output
V1 for 0 to 5 Vdc output
V2 for 0 to 10 Vdc output
MA for 4 to 20 mA output
** - AL for optional relay contact closure outputs

The following steps outline how to install & operate the fiber optic transmitter:
• Install the fiber optic lens probe
• Connect the fiber optic cable to the transmitter front plate. Figure 8 shows the
fiber FC connector (keyed) to the mating transmitter connector. There are two
ports for connections. The temperature port is for measuring temperature. The
laser sighting port is for aligning & positioning the fiber optic lens probe.
• Connect the fiber optic cable to the laser sighting port.
• Connect the power/output cable connector to the mating connector on the
back plate of the transmitter.
• Power the transmitter using a DC power supply. Table 1 (page 2-6) & Figure 6
(page 2-3) show the wiring connections.

• Press the key on the back plate to turn on the laser beam. The laser
power red LED indicator will turn on. The laser beam is projected through the
lens probe. The laser spot represents the optical envelop of the lens probe field
of view. Align & position the lens probe for the proper spot size & distance.
Move the lens probe forward or back until the laser projection is in focus.
Figure 12 shows a typical laser projection through the lens.
• The lens probe is now positioned properly. Press the key again to turn off
the laser beam. The laser power indicator LED will turn off.
• Disconnect the fiber optic cable from the Laser sighting port of the transmitter
and connect to the temperature port for normal temperature measurement.
• Monitor the analog output for temperature measurement.

Main Operations
Figure 9 shows the back panel with all the controls & LED indications as
described below:
High Alarm LED – Red, It turns on when in high alarm condition.
Low Alarm LED – Red, It turns on when in low alarm condition.
Laser LED – Red, It turns on when the laser beam is on.
Power LED – Green, It turns on when the power is on.
Emissivity Dial – The dial allows the user to set the object Emissivity from 0.99 to
0.05 in 0.01 steps.
Gain Adjust – It allows the user to increase or decrease the optical gain. Over
time, some of the fiber strands inside the fiber cable may break due to handling
or stress which can reduce the overall optical gain and the accuracy of the unit.
The gain adjust compensates for the optical gain loss.
& keys – Table 2 shows the operation of the two keys. In order to
leave the Real time mode and get into configuration (Maximum Mode), the
key has to be pressed and held for 2 seconds.
The back panel also accommodates two terminal blocks for Relay options. Each
provides contact closure for high and low alarm built-in relays.

On the mV/Degree analog output models (OS4001-MV), the default output is 1 mV/°F. You can
change the output from 1 mV/°F to 1 mV/°C or vice versa by going through the Configuration menu
with Response time set for 25 msec or higher. At 1 msec response time, the output is fixed at 1 mV/°F.
Polymer Bolt Probe Assemblies
The Polymer Bolt probes are offered at Right angle with quick disconnect as
shown in Figure 13. They come in three standard models as listed below:
Model No. Temperature Range Cable Length
2108-650-RA-1 100 to 425°C (212 to 797°F) 0.3 m (1 Ft)

the time goes on, the temperature graph line gets updated as well as the time
stamping.
6 – The Settings button allows the user to get into the settings menu.
7 – The Go/Stop button allows the user to start/stop the temperature logging.
8 – The Laser button is active when the temperature logging is stopped. Pressing
the Laser button will turn on/off the laser beam in the unit. A laser warning
symbol will also flash when the laser beam is turned on.

9 – The Sound feature allows the user to hear a beep when the process
temperature goes below the low alarm or above the high alarm set points.
10 – COM port can be selected from 1 through 255.
11 – Temp unit allows the user to select the process temperature display in
degrees Fahrenheit or Celsius.
12 – Low & high alarm set points can be set from the two drop down menus.
13 – Output Response selection allows the user to select an analog output
response time anywhere from 1 msec to 3200 msec. You can also select the
Peak-Hold function which will enable the Holding Time drop down menu.
14 – When the History viewer is checked, you can view a history of all the events
with this program.
15 – Chart Time Base allows the user to select the chart speed from 1 minute/
frame to 1 hour/frame.
You can select the Automatic Scaling which will automatically select the chart
temperature range based on the process temperature and the Low & High alarm

set points. You can also set the chart temperature scale manually, if the
Automatic Scaling is not checked.
16 – Holding Time drop down menu allows the user to select the Peak Holding
time from 1 to 60 seconds. This is only active when the Peak-Hold function
is selected from the Output Response Time menu.
17 – When the Save to File is checked, the user can save the logged data into a
data file which can then be imported into Excel for further analysis. Fig 17
shows a typical data file in Notepad.
The data file starts with the starting time, ending time, and the Output response
time which is the data time interval. The first data is the oldest data point. The
last data is the latest data point in the file.

By clicking OK, in the Settings Menu, the program will save all the new settings
in the OS4000 transmitter.

Peak-Hold Function
The OS4000 can be selected for Peak-Hold analog output via. the PC interface
software. The holding time can be selected from 1 to 60 seconds. Figure 18 shows
a typical Peak-Hold analog output time diagram with a Holding Time of 2
seconds.

Signal Averaging (Sample & Hold) Function
The OS4000 provides analog output averaging. This function is desirable when
the process temperature is changing too rapidly and the user is more interested
in the overall trend of the process temperature. Fig 19 shows a fast process
temperature and the corresponding analog output when the response time is set
to 1.6 seconds. The analog output provides an update every 1.6 seconds where
the output is the average of all the sample temperatures within the 1.6 seconds
time period.
