The T100’s exceptional stability is achieved with the use of an optical shutter to
compensate for sensor drift and a reference detector to correct for changes in UV lamp
intensity. Additionally, an advanced optical design combined with a special scrubber,
called a "kicker" that removes hydrocarbons (which fluoresce similarly to SO

Proprietary software allows configurable data acquisition capability that can be triggered
conditionally or periodically, enabling operators to perform predictive diagnostics and
enhanced data analysis by tracking parameter trends. Reports can be downloaded onto a
USB flash drive or via the I/O ports. Operators can also view real-time graphing with one

returned to the factory for repair and/or calibration service.
WARNING – Electrical Shock Hazard
• High Voltages are present inside the instrument’s case.
• Power connection must have functioning ground connection.
• Do not defeat the ground wire on power plug.
• Turn off instrument power before disconnecting or connecting
electrical subassemblies.
•
CAUTION – Avoid Damage to the Instrument
Ensure that the AC power voltage matches the voltage indicated on
the instrument’s model/specs label before plugging it into line
power.
CONNECTING POWER
Attach the power cord between the instrument’s AC power connector and a power outlet
capable of carrying at least the rated current at your AC voltage range. It is important to
adhere to all safety and cautionary messages, and ensure that the outlet is equipped with a
functioning earth ground.

CURRENT LOOP ANALOG OUTPUTS (OPTION 41) SETUP
If your analyzer had this option installed at the factory, there are no further connections to
be made. Otherwise, it can be installed as a retrofit for each of the analog outputs. This
option converts the DC voltage analog output to a current signal with 0-20 mA output
current, which can be scaled to any set of limits within that 0-20 mA range. However, most
current loop applications call for either 2-20 mA or 4-20 mA range. All current loop outputs
have a +5% over-range. Ranges with the lower limit set to more than 1 mA (e.g., 2-20 or
4-20 mA) also have a -5% under-range.
Figure 2-6 provides installation instructions and illustrates a sample configuration of one
current output combined with two voltage outputs. Next are instructions for converting
current loop analog outputs to standard 0-to-5 VDC outputs. To calibrate or adjust these
outputs use the Setup>Analog Outputs menu (Section 2.5.8).
CAUTION – Avoid Invalidating Warranty
Servicing or handling of circuit components requires electrostatic
discharge protection, i.e. ESD grounding straps, mats and
containers. Failure to use ESD protection when working with
electronic assemblies will void the instrument warranty. For
information on preventing ESD damage, refer to the manual,
Fundamentals of ESD, PN 04786, which can be downloaded from
our website at http://www.teledyne-api.com under Help Center >

Map the digital outputs

To convert an output configured for current loop operation to the standard 0 to 5 VDC
output operation:
1. Turn off power to the analyzer.
2. If a recording device is connected to the output being modified, disconnect it.
3. Remove the top cover.
• Remove the set screw located in the top, center of the rear panel.
• Remove the screws fastening the top cover to the unit (one per side).
• Slide the cover back and lift the cover straight up.
4. Remove the screw holding the current loop option to the motherboard.
5. Disconnect the current loop option PCA from the appropriate connector on
the motherboard (see Figure 2-6).
6. Each connector, J19 and J23, requires two shunts. Place one shunt on the
two left most pins and the second shunt on the two adjacent pins (see
Figure 2-6).
7. Return the top cover to the analyzer and secure.
The analyzer can now have a voltage-sensing recording device attached to that output.
CONNECTING THE STATUS OUTPUTS (DIGITAL OUTPUTS)
The 12-pin STATUS connector allows the digital status outputs to report analyzer
conditions (configured through the Setup>Digital Outputs menu) via optically isolated
NPN transistors that sink up to 50 mA of DC current. These outputs can be used to interface
with devices that accept logic-level digital inputs, such as Programmable Logic Controllers
(PLCs). Each status bit is an open collector output that can withstand up to 40 VDC. All of
the emitters of these transistors are tied together and available at pin D (see Figure 2-7).
ATTENTION
COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Most PLC’s have internal provisions for limiting the current that
the input will draw from an external device. When connecting to a
unit that does not have this feature, an external dropping resistor
must be used to limit the current through the transistor output to
less than 50 mA. At 50 mA, the transistor will drop approximately
1.2V from its collector to emitter.
