Warning

Permanent damage may be done to the thermometer if the power supply connections are not done correctly.
In particular, do not connect the power input (18-24VDC) to any of the analog output connectors. Note that
the 20 mA analog output options are self-powered interfaces (by opposition to loop-powered interfaces), and
thus do not require any external supply.

Fiber optic probes are fragile, and will break if the bending radius becomes less than ~1cm, even temporarily.
Probe breakages are not covered under the standard Omega warranty.

NTRODUCTION

Congratulations on the purchase of your FOB100 Series thermometer product! Your new temperature

sensing system will soon allow you to take full advantage of the benefits inherent to fiber optic sensing
technology. It offers accurate and reliable temperature measurements, combined with extraordinary
insensitivity to EMI/RFI, high voltage insulation and disturbance free sensing due to the non-electrical nature
of the sensor element used.

Not only does the FOB100 Series of products gives users’ access to reliable measurements, but it also offers
a simple user interface that makes the technology easy to use. Moreover, no special calibration is required
when changing the fiber optic sensor elements.

The thermometer is packaged in a small splash proof package, which is ideally suited for industrial and
laboratory applications.

The standard configuration is offered with an RS-232 interface as well as an analog output feature (1, 2 or 4
channels) that can be used for remote interfacing purposes. In addition, a green fluorescent display makes it
easy to see the temperature for up to 4 channels, either in Celsius (oC) or in Fahrenheit (oF), even in dark
areas; it also includes a simple 3-key keypad that gives the user access to all built-in features; these standard
features are great for laboratory applications.

An optional software package, FOB100-SOFT, makes your thermometer even more useful. It is easy to use,
and allows the user to easily monitor even multiple thermometers at the same time, and to perform easy data
logging. PC compatible.

• Power supply module (universal input: 100-240VAC, 50/60Hz)

• RS-232C interface cable

• User manual (this manual)

• Calibration Certificate.

Options:

• Fiber optic temperature sensor probes

• Fiber optic extension cables

• Fiber optic coupling

• FOB100-SOFT software (CD).

Make sure all listed items have been received and are in good condition. Note any evidence of rough
handling in transit; immediately report any damage to the shipping agent. Should a part be missing or
damaged, please contact your distributor immediately. Returns must be made with the original packaging,
accompanied by an authorization number (RMA). Omega Customer Service Department will provide you with
information concerning the return of merchandise; you can contact Omega at [phone] or (203) 359-

1660.

The carrier will not honor damage claims unless all shipping material is saved for inspection. After examining
and removing contents, save packing material and carton in the event reshipment becomes necessary.

The following presents a full description of the user interface as well as detailed instructions on how to use
the thermometer.

1) Sensor status light(s): There is a total of up to 4 lights for this, one for each channel. These indicators
inform you about the system status, as applicable to each channel. If any remains off, this indicates that
either that channel is disabled or there is a problem with that sensor (or with the optional patch cord
connected to it). Check if all optical connectors are correctly mated or if the sensor fiber (or patch cord) is not
broken.

Warning: The fiber type that is used with your thermometer is of a special type, and it is
recommended that you get ALL of your patch cords (also called extension cables) from Omega.

9) Analog output connector(s): There are a total of 1, 2 or 4 such connectors, one for each channel. Prior
to shipment, your FOB100 thermometer was factory set to one of the following configurations: 4-20mA or
0-10V output. The minimum analog output value corresponds to minus 100°C and the maximum analog
output value corresponds to 300°C. The thermometer normal range is from minus 80°C to 250°C, so a
minimum value indicates an under-range error; likewise, a maximum value indicates an over-range error
condition. If there is a sensor problem for a given channel, the analog output may take one of the following 3
states (refer to the RS-232 “o” command, Section 5.3):

a) It will toggle between the minimum and maximum values, at approximately 0.5 Hz, this indicates a

sensor problem for that channel (o0). This is the default setting; to change it, you will need to use the

RS-232 “o1” or “o2” command.
b) The analog output is forced to its maximum value (o1); this would indicate a “too-hot” situation.
c) The analog output is forced to its minimum value (o2); this would indicate a “too-cold” situation.

Warning: Do not connect any external voltages to these outputs; this may cause permanent

damage to the thermometer unit.

Note: If the unit is in “sleep” mode, the analog outputs will keep their values until the FOB100 acquires new
temperature values.

10) 18 Volts DC power connector: You can use a DC power supply from 14V to 28V; note that at 15V or
less, you will be unable to use more than one (1) 500Ω load at the analog output, for all current output

configurations. There is an internal fuse, to protect the system in case of electrical problems; this fuse is not
user changeable.
